Introduction 

In December, 2001, and January, 2002, the U.S. Geological Survey (USGS) and 

the Louisiana Geological Survey (LGS), through a Cooperative Research and 

Development Agreement (CRADA) with Devon SFS Operating, Inc. (Devon), 

participated in an exploratory drilling and coring program for coal-bed methane in northcentral Louisiana. The USGS and LGS collected 25 coal core and cuttings samples from 

two coal-bed methane test wells that were drilled in west-central Caldwell Parish, 

Louisiana (fig. 1). Table 1 provides location and other pertinent information for both test 

wells; Devon SFS Operating Co Etal 5 no. 1 (SFS 5-1), and Devon SFS Operating Co 

Etal 9 no. 1 (SFS 9-1). Table 2 provides a list of the sample intervals and a summary of 

the results contained in this report. Field sample depth intervals were later corrected to 

true depth intervals using geophysical logs. Both depths are given on Table 2 because 

many of the analytical data sheets use the original field sample depth intervals. Both, 

USGS/LGS and Ticora Geosciences, Inc. (Ticora; contract laboratory for Devon), 

collected coal core from the two test wells. The purpose of this report is to provide the 

results of the analytical program conducted on the USGS/LGS samples. Analytical data 

from Ticora are not contained in this report; however, their sample intervals are indicated 

on Table 2 and appear on other tables in this report. After the desorption tests were 

complete, splits of the samples collected by Ticora were sent to the USGS laboratories in 
2

Reston, VA, and combined with samples collected by USGS/LGS to form composite 

interval samples used for sorption isotherm analyses. A detailed description of individual 

and interval isotherm samples is contained in the Methane and Carbon Dioxide 

Adsorption Isotherms section of this report. 

The data generated from this project are summarized in the various topical 

sections below. The raw analytical data are contained in several appendices. A summary 

of the analytical results from both wells, including molecular and isotopic data from coal 

gas samples are found in the Summary of Results section below. The results of lowtemperature ashing and X-ray analysis to determine ash mineralogy are summarized in 

the text. The palynology section contains a review of palynological data collected from 

selected samples. Down-hole temperature data from both wells are discussed in the text. 

Appendix 1 contains detailed core descriptions and selected core photographs from both 

wells. Proximate, ultimate, forms of sulfur, ash fusion temperatures, free swelling index, 

apparent specific gravity, and trace and minor element data for samples collected from 

both wells are contained in Appendix 2. Coal gas desorption results are contained in 

Appendix 3, whereas methane and carbon dioxide sorption data from selected samples 

are summarized in the text. Analytical data are presented in Appendix 4. Coal 

petrographic results, including coal maceral composition and vitrinite reflectance data, 

are compiled in the Petrographic section below and in Appendix 5. Images of the 

geophysical logs (natural gamma, caliper, gamma-gamma density, and resistivity) and 

mud logs from both wells are contained in Appendix 6. Digital spread-sheet files for 

various data in this report are found in Appendix 7. Finally, a copy of the CRADA and a 

letter from Devon Energy Corporation that allows release of CRADA proprietary 

information is contained in Appendix 8. 

Summary of Results 

A review of the organic petrology and the low-temperature ash/X-ray mineralogy 

of the coal samples, along with the results of palynological analyses from selected 

intervals of both drill holes are found in subsequent sections of this report. Below is a 
3

summary of the sample intervals and the associated geochemical and gas 

desorption/adsorption and geochemical data found in Tables 2a, 2b, and 3. 

Devon SFS Operating Co Etal 5 no.1 

Cuttings and non-core coal sample intervals: In order to compare desorption results 

from coal cuttings and coal core, the USGS desorbed a total of 33.9 ft of 

predominately coal cuttings in 4 canisters (Table 2a). The cuttings sample 

intervals were selected based on an abundance of coal chips in cuttings: 

composite samples were collected from the following intervals: 1,686.2 to 1,696.0 

ft; 2,039.0 to 2,042.0 ft (non-core); 2,244.2 to 2,247.2 ft; and 2,673.0 to 2,689.0 

ft. All samples were from the Wilcox Group (Paleocene-Eocene; fig. 2). 

Cored intervals: The following intervals were cored during the drilling operation: core 

1: 1,671 to 1,701 ft; core 2: 2,240 to 2,256 ft; and core 3: 2,673 to 2,689 ft. All 

core was from the Wilcox Group (Paleocene-Eocene, fig. 2) (Table 2a). 

Total coal core recovered: A total of 25.9 ft of coal were recovered from three cored 

intervals: core 1 contained 8 ft of coal; core 2 contained 4 ft (includes 1 ft of 

carbonaceous shale); and core 3 contained 13.9 ft. The USGS desorbed a total of 

7 ft of coal core in 5 canisters (Table 2a). 

Moisture contents of coal: The moisture content of the coal samples ranges from 

15.21% to 21.19% on an equilibrium moisture (EM) basis. Equilibrium moisture 

values are used because as-received values may be influenced by the water added 

to the canisters to eliminate headspace and to prevent coal oxidation. (See a 

discussion of desorption methods in the coal gas desorption section of this report.) 

The cuttings samples did not have equilibrium moisture values determined in the 

laboratory (Table 2a). For these samples, equilibrium moisture values were 

estimated using an ash function relationship as illustrated on figure 3. Appendix 2 

contains all values obtained from proximate and ultimate analyses of the coal and 

cuttings samples. Trace and minor element data are also contained in Appendix 

2. 
4

Ash yields of coal: Ash yield of the coal samples ranges from 5.77% to 41.81% on an 

equilibrium moisture basis (Table 2a). Equilibrium moisture values are used 

because as-received values may be influenced by water added to the canisters. 

Appendix 2 contains all values obtained from proximate and ultimate analyses of 

the coal and cuttings samples. 

Estimated coal rank: Estimated ranks using the Parr Formula (ASTM, 2004; standard D 

388) for the coal samples range from subbituminous B to subbituminous A (Table 

2a).

Gas contents of coal: As determined by canister desorption (see Barker and others, 

2002), gas content of the coal core ranges from 31.39 standard cubic ft/ton 

(SCF/ton) to 166.16 SCF/ton on a raw coal (as analyzed) basis, or 73.04 SCF/ton 

to 233.43 SCF/ton on a dry, ash-free basis. Gas content for the coal cuttings 

ranges from 18.23 SCF/ton to 59.06 SCF/ton on a raw coal basis, or 40.67 

SCF/ton to 121.57 SCF/ton on a dry, ash-free basis (Table 2a). Because of rapid 

desorption and presumably high lost-gas values, the coal cuttings gas content 

values on a dry ash-free basis are increased by 25% in an effort to better estimate 

the true gas content of the original coal (Mavor and Nelson, 1997; Nelson, 1998; 

Barker and others, 2002). A plot of the gas content values of the coal cuttings and 

coal core is shown on figure 4. Gas content values obtained from coal cuttings do 

not match the values obtained from the coal core that was obtained from similar 

depths. Mavor and Nelson (1997) and Nelson (1998) attribute decreased cuttings 

gas content to a reduction in the average gas diffusion distance within cuttings 

particles and a general mixing with rock cuttings extraneous to the reservoir. The 

rank and gas content of the coal samples increases with depth. A complete set of 

desorption data sheets are contained in Appendix 3. (Note that field depths and 

thicknesses are used in Appendix 3.) 

Adsorption isotherm data: Multiple adsorption isotherm analyses were run on both 

individual and composite coal samples from the Devon SFS Operating Co Etal 5 

no. 1 (SFS 5-1) well. A list of samples selected from each well is contained in 

Appendix 4. Figure 5 shows plots of sorption isotherm data and measured gas 

desorption data from two samples from the SFS 5-1 well. The shallow coal 
5

sample (4-LA-1, depth 1,685.2-1,686.2 ft) is under-saturated with respect to 

methane, whereas the deep sample (4-LA-2, depth 2,679-2,680 ft) is above the 

predicted saturation with respect to methane. The complete data set for all 

sorption isotherms are contained in Appendix 4. 

Gas molecular and isotopic data: No coal gas samples were collected from the SFS 5-1 

well. 

 

Devon SFS Operating Co Etal 9 no.1 

Cuttings and non-core coal sample intervals: In order to compare desorption results 

from coal cuttings and coal core, the USGS desorbed a total of 9.2 ft of 

predominantly coal cuttings in 5 canisters (Table 2b). The sample intervals were 

selected based on an abundance of coal chips in the cuttings. The sample 

intervals (corrected depths) are from 2,053 to 2,055 ft (non-core); 2,688 to 2,689 

ft, 2,689 to 2,690 ft, and 2 composite samples were collected from 2,692.3 to 

2,697.5 ft depths. All samples were from the Wilcox Group (Paleocene-Eocene, 

fig. 2). 

Cored intervals: The following intervals (corrected depths) were cored during the 

drilling operation: core 1: 1,646.6 to 1,676.6 ft; core 2: 2,214.3 to 2,231 ft; core 3: 

2,256 to 2,284 ft (base depth of core 3 is not certain); and core 4: 2,682.6 to 

2,698.5 ft depths. A total of 90.6 ft of core was recovered. All cores were from 

the Wilcox Group (Paleocene-Eocene, fig. 2) (Table 2b).

Total coal core recovered: A total of 24.8 ft of coal was recovered from the four cored 

intervals: core 1 (30 ft) contained 2.4 ft of coal; core 2 (16.7 ft) contained 6.2 ft; 

core 3 (28 ft) contained 6.5 ft (includes 0.5 ft carbonaceous shale); and core 4 

(15.9 ft) contained 9.7 ft (includes 1 ft carbonaceous shale). The USGS desorbed 

a total of 6.3 ft of coal core and 4.9 ft of composite coal core in 11 canisters 

(Table 2b).

Moisture contents of coal: The equilibrium moisture (EM) content of the coal samples 

(Table 2b) ranges from 19.94% to 28.83%. For the carbonaceous shale core 

samples, moisture ranges from 9.96% to 18.54% (EM). Equilibrium moisture 
6

values are used because as-received values may be influenced by the water added 

to the canisters. (See a discussion of desorption methods in the coal gas 

desorption section of this report.) The cuttings samples did not have equilibrium 

moisture values determined in the laboratory (Table 2b). For these samples, 

equilibrium moisture values were estimated using an ash function relationship as 

illustrated on figure 3. Appendix 2 contains all values obtained from proximate 

and ultimate analyses of the coal and cuttings samples, along with trace, and 

minor element data.

Ash yields of coal: Ash yield (EM Ash %) of the coal samples ranges from 8.47% to 

44.7% (EM), and for the carbonaceous shale samples ash yield ranges from 

49.17% (technically coal) to 75.27% (EM) (Table 2b). Equilibrium moisture 

values are used because as-received values may be influenced by water used in 

the canister. Appendix 2 contains all values obtained from proximate and 

ultimate analyses of the coal and cuttings samples.

Estimated coal rank: Estimated ranks using the Parr Formula (ASTM, 2004, standard D 

388) for the coal samples range from subbituminous C to subituminous A (Table 

2b).

Gas contents of coal: As determined by canister desorption (see Barker and others, 

2002), gas content of the coal core ranges from 32.39 standard cubic ft/ton 

(SCF/ton) to 127.83 SCF/ton on a raw coal basis, or 83.38 SCF/ton to 183.83 

SCF/ton on a dry, ash-free basis. Gas content for the carbonaceous shale core 

samples ranges from 11.87 SCF/ton to 51.31 SCF/ton on a raw coal basis, or 

38.41 SCF/ton to 293.17 SCF/ton on a dry, ash-free basis. Gas content for the 

coal cuttings ranges from 21.34 SCF/ton to 31.97 SCF/ton on a raw coal basis, or 

40.24 SCF/ton to 71.67 SCF/ton on a dry, ash-free basis. Because of rapid 

desorption and presumably high lost gas values, the coal cuttings gas content 

values on a dry ash-free basis are increased by 25% in an effort to better estimate 

the true gas content of the original coal (Barker and others, 2002). A plot of the 

gas content values of the coal cuttings and coal core is shown on figure 4. Note 

that coal cuttings gas content values do not match the values obtained from the 

coal core canisters. The rank and gas content of the coal samples increases with 
7

depth. A complete set of desorption data sheets are contained in Appendix 3. 

(Note that field depths and thicknesses are used in Appendix 3.) 

Adsorption isotherm data: Multiple adsorption isotherm analyses were run on both 

individual and composite coal samples from the Devon SFS Operating Co Etal 9 

no. 1 (SFS 9-1) well. A list of samples selected from each well is contained in 

Appendix 4. Figure 5 shows plots of sorption isotherm data and measured gas 

desorption data from one sample from a middle Wilcox coal bed from the SFS 9-1 

well. The coal sample (4-LA-8) is under-saturated with respect to methane. The 

complete data set for all sorption isotherms is contained in Appendix 4.

Gas molecular and isotopic data: Five coal gas samples were collected from the 

manometer during the desorption of coal core and cuttings samples from the SFS 

9-1 well in Caldwell Parish, LA. The results of molecular and isotopic analyses 

are listed on Table 3. Because\of air contamination in the manometer, the 

molecular data have been corrected to an oxygen-free (O-free) basis. Methane 

(C1) content for the coal core samples ranges from 90.93 to 97.11%, O-free basis. 

The methane content of the cuttings gas sample (62.83% O-free) is lower than 

that of the coal core samples and is probably due to strong air contamination of 

the cuttings sample (9.73% O, raw basis). Coal gas isotopic data indicates δ13C1

values range from -62.66‰ to -60.73‰ relative to the Pee Dee Belemnite (PDB), 

and δDC1 values range from -196‰ to -193‰ relative to Standard Mean Ocean 

Water (SMOW). Using the Whiticar and others (1986) δ13C1-δDC1 diagram to 

interpret the origin of natural gases, the coal gases from the SFS 9-1 coal samples 

were determined to be derived from bacterial reduction of CO2 (fig. 6). 

Petrography 

Methods 

Coal and carbonaceous shale samples from two test wells in northern Louisiana 

(Devon SFS Operating Co Etal 5 no. 1, and Devon SFS Operating Co Etal 9 no. 1; fig. 1) 

were ground to pass -16 mesh, cast in epoxy, and polished following the procedures 
8

outlined in Pontolillo and Stanton (1994). Two sample mounts were made from each 

sample. Measurement of maximum huminite reflectance in immersion oil (Rmax) was 

performed according to the ASTM D2798 protocol (ASTM, 2002). Results of 

reflectance measurements are found in Appendix 5. 

The samples also were examined in blue-light fluorescence by a modification of 

ASTM D2799 (ASTM, 2002). Identifications of liptinite or non-fluorescing 

organic/mineral matter were made at 500 points on each sample mount. Identifications of 

huminite and inertinite macerals were made at 500 points on each mount under oil 

immersion in white light. Identification of coal macerals follows the maceral 

nomenclature proposed by the International Committee for Coal and Organic Petrology 

(ICCP System 1994) (ICCP, 2001; Sýkorová and others, 2005). Volume percent mineral 

matter was calculated from the Parr formula (ASTM, 2004, standard D388). Results of 

petrographic analyses are found in Appendix 5. 

Petrographic Analyses 

Coal sample macerals (Appendix 5, Tables 2a and 2b) are dominated by huminite 

(avg. 71 vol.%; range 49-96 vol.%, mineral-free basis), followed by inertinite (avg. 20 

vol.%; range 1-40 vol.%), and liptinite (avg. 9 vol.%; range 3-19 vol.%). Mineral content 

as determined by the Parr formula averages 26 vol. % (range 4-82 vol.%). Most samples 

contain approximately equal proportions of telohuminite and detrohuminite; however, 

some samples are dominated by one huminite type over another (e.g., 4-LA-1). Inertinite 

content typically is dominated by semifusinite or inertodetrinite, followed by 

approximately equal amounts of fusinite and macrinite. Funginite, macrinite, and 

secretinite (sensu fusinitized corpohuminite) are present in amounts of <1 vol.%. 

Liptinite group macerals typically are dominated by liptodetrinite (avg. 5 vol.%), 

followed by sporinite (avg. 1.5 vol.%). Structured liptinite macerals cutinite and 

suberinite are rare or absent. A summary of the volume percent of the major maceral 

groups and mineral matter for each well is illustrated on figure 7. 
9

Huminite Reflectance 

The maximum reflectance of huminite (telohuminite) ranges from 0.28-0.47%. 

Measured values of reflectance increase with depth. Measured values are limited to a 

maximum of 0.40% at the bottom of SFS 9-1 and are slightly higher in SFS 5-1 

(maximum values 0.42-0.47%). Coal rank as determined by reflectance is lignitesubbituminous B. 

Low Temperature Ashing and X-ray Analysis 

 Eighteen representative samples from the two test wells in northern Louisiana 

(Devon SFS Operating Co Etal 5 no. 1, and Devon SFS Operating Co Etal 9 no. 1; fig. 1; 

Table 4) were ground to -200 mesh (75 μm) in a rotary mill, oven-dried overnight, and 

ashed in a LTA-504 asher at 100o

C. The samples were weighed daily on a five-decimalplace balance until no more weight loss could be determined. Table 4 lists the lowtemperature ashing results. The samples were then cast into pressed pellets and analyzed 

on a Scintag X1 automated powder diffractometer. The mineralogical quantification 

program used to determine mineralogy is a modified version from Hosterman and Dulong 

(1989). The kaolinite/chlorite ratio (K/K+C) was calculated from the quantification 

program’s determination of the integrated intensities for the 002 and 004 kaolinite and 

chlorite peaks. The peak width at half maximum (PW) in degrees two-theta of the 001 

illite peak was determined using the raw intensity (CPS) data. Table 5 contains a 

summary for each sample describing the semi-quantitative mineralogy. Samples LASWC-00-3 (RBF15614) and 3-LA-8 (RFB15617) contain a rectorite (illite/smectite). 

The factor used in the quantification of rectorite was not experimentally determined and 

therefore the entire quantification of those samples are a “best guess”. Table 6 contains a 

narrative for each sample describing the semi-quantitative mineralogy. 
10

Palynology 

Nine samples from multiple coal zones in the Wilcox Group were selected from 

both wells (Devon SFS Operating Co Etal 5 no. 1, and Devon SFS Operating Co Etal 9 

no. 1; fig. 1) for palynological analysis (Table 7). All samples analyzed are coal. The 

drill holes are located 1.8 miles apart (fig. 1), and given their close proximity, the 

different results from each are somewhat surprising. 

The sampled interval in the SFS 5-1 well ranges from 1679.2 to 2679.5 feet in 

depth; the sampled interval in the SFS 9-1 well ranges from 1651.6 to 2693.3 feet in 

depth. The age of the sampled intervals in both wells is Paleocene, and the palynofloral 

assemblages in each are closely similar, comprising common Wilcox species. Species 

having more specific biostratigraphic significance, for example species indicative of late 

Paleocene age, are present in samples from the SFS 9-1 well that were not recorded in 

samples from SFS 5-1. For this reason, close correlation of the two intervals is not fully 

supported on the basis of palynostratigraphy. Slightly differing assemblages in the two 

wells could be due to slight differences in the floras of the ancient mires, although such 

differences are subtle, involving only a few species. Detailed biostratigraphic age 

determinations are based on comparisons with palynomorph species ranges in the Rocky 

Mountain region. Table 8 contains a species lists and photomicrograph reference number 

for Plates 1 and 2 of common Wilcox palynomorphs. Tables 9 and 10 illustrate the 

pollen distribution versus depth for the two wells. 

Coal Gas Desorption Analyses 

The coal and carbonaceous shale core and cuttings samples collected from the two 

test wells in northern Louisiana (Devon SFS Operating Co Etal 5 no. 1, and Devon SFS 

Operating Co Etal 9 no. 1; fig. 1; Tables 1 and 2) were placed in canisters and desorbed 

gas was measured and lost gas was estimated following the procedures outlined in Barker 

and others (2002). The target desorption water bath temperatures used for the canisters 

were determined by Devon to be an estimate of reservoir temperature and were based on 
11

down-hole temperature data obtained from nearby well logs. Samples from the upper and 

middle Wilcox coal-bearing intervals were desorbed at 100o to 110oF, and samples from 

the lower Wilcox coal-bearing interval were desorbed at 120o

F (Tables 2a and 2b). The 

desorption results, lost gas estimates, and estimated total gas content for each sample are 

contained in Appendix 3. The analytical results are also summarized on Table 2 and in 

the Summary of Results section above. Residual gas was not measured for the samples in 

this study and therefore the estimates of total gas content should be considered a 

minimum value. Nelson and others (2000) report that residual gas in subbituminous coal 

from the Powder River basin in Wyoming is as much as 6 percent of the total gas content 

of the coal. The coal and carbonaceous shale samples analyzed in this study were 

allowed to fully desorb in the canisters; therefore the residual gas content should be very 

low. Residual gas probably only accounts for 2 to 3 percent of the total gas content and 

most likely will not be producible. 

Coal Physical and Chemical Analyses 

After the gas desorption process was complete, the coal and carbonaceous shale 

core and cuttings samples were removed from the canisters, described in the laboratory, 

and split and packaged for further analyses. Photographs and lithologic descriptions of 

the desorbed samples are contained in Appendix 1. Solid core samples were split in half 

using a rock trim saw. One of the half splits of each core sample was packaged in airtight plastic bags and sent to contract laboratories for proximate, ultimate and other 

physical and chemical analyses. The results of these analyses are found in Appendix 2. 

The remaining core sample half was split again into halves (quarters of the original core). 

One half (or quarter of the original core) of the remaining split was placed in archive 

storage at the USGS laboratories in Reston, VA; the other half (quarter of the original 

core) was used for individual or composite samples that were submitted for sorption 

isotherm analyses. Tables 1a and 1b of Appendix 4 list the individual samples and 

sample intervals that were used to form the composite samples for sorption isotherm 

analyses. 
12

Methane and Carbon Dioxide Adsorption Isotherms 

High-pressure methane adsorption analysis was carried out on three individual 

core samples and seven composite samples collected from two test wells in northern 

Louisiana (Devon SFS Operating Co Etal 5 no. 1, and Devon SFS Operating Co Etal 9 

no. 1; fig. 1; Appendix 4 Table 1). High-pressure carbon dioxide adsorption analysis was 

carried out on the three individual core samples from both wells and the composite 

samples from the Devon SFS Operating Co Etal 5 no. 1 well (Appendix 4 Table 1). The 

composite samples of the upper, middle, and lower coal zones were compiled by adding 

10 g of sample for every 0.1 ft of coal or carbonaceous shale core. For example, if a 

sample interval was 1 ft thick, then the contribution to the composite sample was 100 g; 

if a sample interval was 0.3 ft thick, then the contribution to the composite was 30 g. All 

composite samples consisted of representative splits derived by the quartering method. 

Samples desorbed by both USGS/LGS and Ticora were used to form the composite 

samples. The analytical methods to determine the adsorption isotherms are summarized 

below and the analytical results are contained in Appendix 4. Adsorption isotherm 

temperatures for the various samples were determined by comparing the sample depth 

interval to down-hole temperature log data from the two wells (fig. 8). The sorption 

isotherm temperature for upper Wilcox coal samples was 97o

F; middle Wilcox coal 

samples was 108oF; and lower Wilcox coal samples was 118oF. 

Methods 

The samples were received at the RMB Earth Science Consultants laboratory wet 

and in a mud-like or slurry state. Because of the susceptibility of the samples to over 

drying and oxidation, they were carefully dried in an inert atmosphere and then placed in 

an equilibrium bath. If low-rank coals are dried it is virtually impossible to return them 

to equilibrium moisture and, at less than equilibrium moisture, the capacity of the coals is 

much higher. On the other hand, excess moisture does not adversely affect sorption apart 
13

from the moisture diluting the samples. Hence the samples were, if anything, left 'wetter' 

than equilibrium moisture. If the in-situ moisture content of the coals were known, the 

results from this study could be adjusted by considering the moisture in excess of 

equilibrium moisture as a diluent. 

The sorption analyses were carried out following the general procedures outlined 

below. 

Obtaining and interpreting isotherm data and Langmuir 

Isotherms 

These high-pressure methane, carbon dioxide or mixed gas adsorption analyses 

were performed using a high-pressure volumetric adsorption technique. The isotherms 

were measured on a custom-made apparatus based on Boyles Law. A known volume of 

gas within a reference cell is used to dose a sample cell containing the sample. The 

amount of gas adsorbed, using the real gas law, in the sample cell is then determined 

based on change in pressure in the sample cell. Normally 100 g of sample is utilized in 

such analyses although a full 3.5 inch core, up to 12 inches in length, can be used. Tests 

show that reproducible results can be obtained on samples as small as 5 g but the larger 

samples yield better quality data. Each sample has multiple adsorption analyses using a 

constant temperature (usually reservoir temperature) and increasing pressures to simulate 

overburden pressures related to depth of burial. 

The pressures in the reference and sample cells are measured using pressure 

transducers that are interfaced to a computer equipped with specialized boards and 

software for this purpose. The computer monitors the transducers, determines when 

equilibrium is reached, and controls valves and switches for dosing and purging the 

reference and sample cells. Following dosing of the sample cell with a known volume of 

gas (CH4 or CO2, depending on the test), the pressure in the sample cell is monitored. As 

gas is adsorbed by the sample the pressure drops until equilibrium is reached; that is no 

more gas can be adsorbed by the samples at that particular specified pressure. Critical to 

obtaining quality isotherms is deciding when the equilibrium is reached. In the current 
14

instrumentation, test equilibrium is reached only when the pressure in the cell does not 

change over a designated period of time. When equilibrium is reached, the sample is 

dosed at a higher pressure. Normally, nine to 12 separate pressure points are collected so 

that the best Langmuir regression can be obtained. Data points can also be collected at 

pre-determined pressures if needed. The temperature of the references and sample cells 

is maintained at the exact temperature requested by the client. The temperature is 

maintained within a tolerance less than 1/10 of one degree centigrade. 

For a routine adsorption analysis about five to seven days are required once 

equilibrium moisture has been determined. 

For calculation of the head space (space not occupied by sample in the bombs) 

and helium density, 12 separate helium expansions are automatically performed and 

averaged. The compressibilites of the various gases required for volumetric calculations 

at each pressure and temperature are obtained using the Peng-Robinson equation of state 

(Peng and Robison, 1976) utilizing the SUPERTRAPP program (Huber, 2003). 

Quality assurance of the isotherms: potential sources of error 

and recognition of problems 

With the apparatus that is used, the only potential error is a change in the 

characteristics of the pressure transducers, a leak in the system, or non-isothermal 

conditions. 

Pressure transducers were selected for optimum performance within the range of 

pressures that isotherms are collected. The transducers are not only factory guaranteed, 

but are also cross-calibrated periodically to test for drift. The accuracy of the transducers 

used is better than 0.001 MPa. 

Prior to running the experiment, the reference and sample cells and plumbing are 

pressure tested for leaks using helium. Leak tests are performed at 9 MPa. Because the 

He molecule is smaller than either methane or carbon dioxide (the gases normally used 

for adsorption work), He assures a leak free system. If a leak were to develop during 

analyses (one never has) it would be readily apparent because the cells would never come 
15

to equilibrium at a given pressure (the leak would appear as an infinitely adsorbing 

material). 

Non-isothermal conditions are not a potential problem with the instrument used, 

unless a prolonged power failure occurs. The bath temperature is maintained by a 

submerged electric heater and a circulating pump. The heater is controlled by a 

temperature controller to a tolerance less than 1/10 of a degree centigrade. 

Standard samples periodically are run in the apparatus to confirm system 

performance. 

The Langmuir model 

The classic theory used to describe the Type I isotherm for microporous materials 

with small external surface area is based on the Langmuir (1916) equation. The Type I 

isotherm displays a steep increase in adsorption at low relative pressures due to enhanced 

adsorption caused by the overlapping adsorption potentials between walls of pores whose 

diameters are commensurate in size with the adsorbate molecule. The Type I isotherm 

then flattens out into a plateau region at higher relative pressure, which is believed to be 

due to the completion of a monolayer of adsorbed gas. The micropore volume is then 

thought to be filled by only a few molecular layers of adsorbate, and further uptake is 

limited by the dimensions of the micropores. 

The Langmuir model assumes that a state of dynamic equilibrium is established 

between the adsorbate vapor and the adsorbent surface and that adsorption is restricted to 

a single monolayer (Gregg and Sing, 1982). The adsorbent surface is thought to be 

composed of a regular array of energetically homogeneous adsorption sites upon which 

an adsorbed monolayer is assumed to form. The rate of condensation is assumed to be 

equal to the rate of evaporation from the adsorbed monolayer at a given relative pressure 

and constant temperature. The Langmuir equation was developed with these assumptions 

and takes the following form: 
16

m Vm

P

V BV

p = +1

 

where P is the equilibrium pressure, V is the volume of gas adsorbed at equilibrium, Vm

is the volume of adsorbate occupying a monolayer, and B is an empirical constant. A 

plot of P/V versus relative pressure should yield a straight line whose slope will yield Vm

from which the surface area may be obtained. As shown on the figures in Appendix 4, a 

best fit Langmuir isotherm and the data points have been plotted for each sample. 

The Langmuir Isotherm can be written: 

P P

V P V P

L

L

+

( ) =

 P = gas pressure 

V(P) = predicated amount of gas adsorbed at P 

VL = Langmuir volume parameter 

PL = Langmuir pressure parameter 

The difference between the measured amount of gas adsorbed (V(P)) and that predicted 

using the Langmuir Equation (Vi(P)) is a measure of error and is given as: 

Err(P) = Vi(P) - V(P)

This error may be positive or negative. The square of the error is always positive and is a 

measure of the how well the calculated isotherm matches the data. This error can be 

calculated for each point and summed giving a measure of the overall error: 

∑=

=

N

i i

SSE Er r

1

2

N= number of measured points. 
17

The goodness of fit of the isotherm can be expressed by calculation of the correlation 

coefficient between the measured points and the calculated points. Results generally 

yield correlations that are better than r2 = 0.99 and standard errors of Langmuir volumes 

of 2%. The errors for the Louisiana samples can be found on the bottom of the data 

sheets that are included for each sample in Appendix 4. 

 In examining the data, note that adsorption values are provided for the raw data 

and corrected for ash yield. The ash yield will also be corrected for equilibrium moisture 

content. 

 Results 

The results of the high-pressure methane analysis of the samples are summarized 

in Appendix 4 in Imperial and SI units. Note that STP in SI units is at 0°C whereas in 

Imperial units (standard oil industry convention) STP is at a temperature of 60° F. 

Detailed plots of the isotherm results are provided in Appendix 4. 

Down-hole Temperature Data 

 Temperature surveys were run on both wells (Devon SFS Operating Co Etal 5 no. 

1, and Devon SFS Operating Co Etal 9 no. 1; fig. 8) and the data were used to estimate 

the reservoir temperatures for adsorption isotherm analyses (Appendix 4). The 

temperature data were obtained by shutting-in the well at various depths and allowing the 

down-hole temperature to equilibrate with down-hole ambient conditions. The data 

shows a gradient of around 2 degrees/100 ft through the Wilcox interval. Both wells are 

about the same temperature near the top of the Wilcox (~1,700 ft), but the Devon SFS 5-1 

well is slightly hotter than the Devon SFS 9-1 (about 2 degrees) at a depth of 2,700 ft. 

The elevated down-hole temperatures for the Devon SFS 5-1 well may be related to the 

well’s proximity to the Chester salt dome (fig. 1) and possible increased geothermal heat 

flow through the salt.

Report Information 

Results of petrographic analyses of coal and rock samples in the U.S. Geological 

Survey Organic Petrology Laboratory usually are reported in three parts; 1) a summary 

table, 2) a petrographic analysis report, and 3) a vitrinite reflectance report. 

The summary table includes the name of the sample submitter, the name of the 

analyst or report writer, and the date of report preparation. The petrographic data are 

summarized in tabular format and usually include vitrinite reflectance values, gross 

maceral group composition, and mineral matter content. 

The petrographic analysis report includes five components; 1) a header with basic 

sample information including sample submitter, submission date, project name, sample 

identification, sample type, date of analysis, the name of the analyst, the number of points 

counted, and the sample rank as determined by vitrinite reflectance, 2) a bar chart 

showing gross maceral group composition on a mineral-matter-free basis (volume percent 
444

of organic matter basis), 3) a bar chart showing organic composition on a mineralcontaining basis (volume percent of whole coal/rock), 4) a data table listing the measured 

amounts of the individual organic components on mineral-containing and mineral-free 

bases, and 5) a comment section which allows the analyst to record any pertinent details 

about the petrographic character of the sample. 

The vitrinite reflectance report includes five components; 1) a header with basic 

sample information including sample submitter, submission date, project name, sample 

identification, sample type, date of analysis, and the name of the analyst, 2) results, 

including the number of vitrinite reflectance measurements, the type of vitrinite maceral 

analyzed, the mean maximum or mean random reflectance value, the standard deviation 

of the mean reflectance value, and the sample rank, 3) data, which contains all of the 

measured reflectance values to three decimal places, the maximum and minimum 

measured values, and the number of V-types (reflectance ranges of 0.1 percent), 4) a 

histogram of the reflectance data, and 5) a comment section which allows the analyst to 

record any pertinent details about the petrographic character of the sample. Contained 

within the reflectance digital spreadsheets in Appendix 7 are worksheets for “Data entry” 

and “Chart data” (contains frequency data) used to generate the graph on the “Report and 

chart” worksheet.

COMMENT

Pyrite-rich, some cleat-filling pyrite. Difference in inertinite content A vs B pellet probably reflects poor polish on B pellet. Beautiful suberinite 

present. More likely difference in pellet point counts reflects destruction (vs enlightenment) of B pellet via etching. So report uses data only 

from A pellet, whereas data for both pellets are recorded in LA-SWC-01-3 spreadsheet.

Sample described as shaley in field notes. Coal particles in sample mount are mineral-rich attrinite, probably greater than 50 percent of particles 

are dispersed inertodetrinite-vitrodetrinite in bituminite-mineral matter groundmass. 250 points counted on each pellet in oil immersion. 

Dispersed vitrinite particles <10um counted as attrinite. n.d. = not determined.

COMMENT

beautiful exudate in bogen fusinite texture in flourescence. Resinite poor compared to other Wilcox samples. In oil, sample appears to contain 

mostly attrital huminite, some durite fragments, most of the telohuminite appears to have undergone some oxidation, shrinkage cracks, etc. 

Sample may have been stressed during preparation, creating microfaults, disaggregated texture. This texture is present in both mounts and 

probably reflects in situ stress.

Statement of Work 

Cooperative Research and Development Agreement 

between 

U.S. Geological Survey, Devon SFS Operating, Inc., 

and Louisiana State University, Louisiana Geological Survey 

for 

North-Central Louisiana Coalbed Methane Investigations 

Purpose 

Domestic and international shortages of natural gas are prompting a reevaluation of coal and natural gas 

resources in the United States. A major mission of the U.S. Geological Survey (USGS) is to find and 

identify the energy resources of the country. In many locations, reliable information on the thickness of 

various coal beds and the presence of coal bed methane (CBM) is not available. Many coal-bearing areas 

have not been characterized by gas desorption data from coal core samples and by modern geophysical logs 

that include gamma and neutron density. 

The purpose of this Collaborative Research and Development Agreement (CRADA) is to obtain and 

characterize necessary modern coal core samples from the largely un-explored north-central Louisiana coal 

basin. The findings of this research will be published so that, if economic CBM is present in the region, the 

resources can be developed in a systematic and environmentally sound manor that benefits the American 

public and the economics of the region. 

The parties to the CRADA are the USGS Energy Resources Team, (ERT), the Louisiana State University, 

Louisiana Geological Survey (LGS), and the industrial partner, Devon SFS Operating, Inc. (Collaborator/ 

Devon) engaged in the exploration, development and production of oil and natural gas. 

Objectives 

Recent investigations by Devon, the LGS, the USGS, and others suggest the potential for significant CBM 

stored in the coals of the north-central Louisiana coal basin. To date, only two or three CBM wells have 

been tested in the area, and the data are not publicly available. Available data from conventional oil and gas 

wells in the area, suggests that there are three or more coal zones within Wilcox Group (Paleocene-Eocene) 

strata in the north-central Louisiana coal basin that may have potential for significant coalbed methane 

accumulations. The primary goal of this joint project is to core portions of the three primary coal zones of 

the Wilcox Group and develop geologic models for the occurrence of coal and CBM in the Wilcox coals of 

north-central Louisiana. The possibility of CBM sourced from coals in this region has been discussed by 

the USGS and LGS with multiple state and private organizations for several years. This project constitutes 

the first major effort in the region to quantify the stratigraphy and facies of coal occurrence as well as 

provide more data on total coal tonnage and the basin gas content and character. 

Under the project plan, two initial wells will be drilled in late 2001 and early 2002. Devon will cover the 

cost of site preparation and reclamation, drilling, coring, mud logging, geophysical logging, testing of 

selected coal samples for gas content (by desorption), insurance, well capping or completion, all required 

permits, and other activities related to normal testing and completion of Wilcox coal zones for two wells 

508
located in Caldwell Parish, Louisiana. The USGS will provide additional advanced analytical 

characterizations (including desorption) for selected core and cuttings samples from the two wells. For 

selected coal samples, tests will include: proximate and ultimate analyses; adsorption isotherms for CH4 and 

CO2; X-radiograph and detailed megascopic description; vitrinite reflectance and standard petrography. In 

addition molecular and isotopic analyses will be run on selected gas samples. Other tests such as 

palynology, trace element characterization, and radiometric age dating may be performed on a few samples. 

If the wells are productive, USGS may provide analyses of co-produced water. The LGS will provide wellsite support for sample collection and will help to integrate the analytical results into regional subsurface 

maps and models that can be used to estimate and predict the CBM resources of the north-central Louisiana 

coal basin. It is expected that initial analytical data (desorption, adsorption, and gas analyses) will be 

complete within 4 to 6 months after the first two drill holes are completed. Coal petrography and other 

mentioned analytical work might take several months longer to complete. 

The data developed by the Parties under the scope of work will be considered as Protected CRADA 

Information for a period of three years from the time that core-data is shared, and becomes available for 

joint public reports, publications and presentations describing the geology, occurrence and geochemistry of 

coal and CBM in the north-central Louisiana coal basin. 

The results of this research will be a boost to the potential commercial development of the CBM resources 

in the north-central Louisiana coal basin. 

Collaborator’s Role 

Devon SFS Operating, Inc will select the drill sites, provide all construction, maintenance and rehabilitation 

of drill site access roads, drilling pads, mud pits, and diverter flow pits, insurance, and permitting required 

for the operation. The drill sites will be selected to maximize the gain of new data by being placed far away 

from all existing CBM wells. 

Devon will also assist USGS and LGS in cooperative mapping of the depth to the Wilcox coal zones, the 

extent of the coal basin, number of coalbeds, the net coal thickness for the north-central Louisiana coal basin 

using existing subsurface logs and seismic data. To accomplish these goals, Devon will provide 

management, personnel, funds and technology transfer as listed in Specific Tasks below. Devon’s in-kind 

contribution to this project is estimated to be $500,000. 

Specific Tasks

Devon SFS Operating, Inc.

1) Provide drill site selection, determination of core point and cored interval thickness. Provide logs and 

any other relevant data (excluding seismic) that they possess by virtue of the two wells in Caldwell Parish, 

LA. 

2) Provide all drilling permits, bonds, and insurance or other State of Louisiana or U.S. Government 

requirements for drilling CBM test wells. 

3) Provide road grading pad clearing and preparation of mud pits, diverter blow pits or other necessary 

improvement for drilling rig access. 

4) Provide contract support for drilling, coring, mud logging, geophysical logging, normal site maintenance, 

and CBM desorption data acquisition for selected coal samples from the cored intervals. 

5) Provide the appropriate personnel to assist with real time collection of coal, rock, gas, water samples, and 

509
general well drilling and contractor supervision. 

6) Assist with the interpretation of all data including desorption, log, and reservoir test data and in the 

preparation of reports and presentations. 

7) Devon will pay the cost of abandonment, in the event that one or both wells have to be abandoned. 

8) Provide for reclamation of the wellhead and drilling pad as required by the permits or bonds issued by the 

State of Louisiana or the U.S. Government. Devon SFS Operating, Inc. will also indemnify the USGS and 

the LGS from any liability for environmental or land reclamation caused by drilling activities or injury or 

damage to Devon SFS Operating, Inc. personnel or equipment resulting from drilling operations unless 

caused by negligence on the part of the USGS, LGS or their agents. 

9) At the conclusion of the drilling operations for each of the two wells in Caldwell Parish, Devon SFS 

Operating, Inc. will have full control of the wellbore and it may use it for whatever purposes it so desires 

(including gas production). 

USGS Role 

The USGS role is to assist in collection of samples selected for their specialized analytical tests. All 

equipment and coal and rock, gas and water samples developed or collected by the USGS during this 

program will be retained by the USGS. Such coal and rock samples gained during this cooperative project 

will be stored in the USGS ERT core facilities in Reston (VA) or Denver (CO) for the term of the 

agreement. Coal and rock cores collected by the Devon will be stored at C&M Storage Inc., Schulemburg, 

TX by Devon for the term of the agreement, Devon will have access to study the coal and rock core samples 

in the USGS Library in Reston or Denver by giving written notice to the USGS of its desire to do so. The 

USGS and /or LGS will have access to study the coal and rock core and samples stored by the Devon by 

giving written notice of their desire to do so. 

With prior Devon approval, coal and rock cuttings may be sampled from subsequent developmental drill 

holes drilled by Devon for the purposes of comparison between the original two cored holes and subsequent 

non-cored drill holes. The USGS is especially interested in those holes that may be sited over salt domes. 

The purpose of this portion of the study is to compare rank, gas content, adsorption isotherm, gas 

hydrocarbon and isotopic composition of the coal and produced water over the salt dome with similar data 

gathered from coals sampled from the previously drilled holes. 

USGS will arrange for the appropriate chemical and physical characterization of the all coal and selected 

rock samples at their analytical facilities in Denver and Reston. Commercial or university laboratories may 

characterize some samples. USGS in-kind contribution to this project is estimated to be $75,000. 

Specific USGS scientific tasks include: 1) determination of gas content by canister desorption of selected 

coal cuttings and core (not analyzed by Devon’s contract desorption company) that are cut from the two 

cooperative exploration drill holes in north-central Louisiana; 2) determination of coal rank, facies and 

properties from ultimate and proximate analysis, X-radiograph and detailed megascopic description, 

adsorption isotherms for CH4 and CO2, vitrinite reflectance and standard petrography; 3) study of coal cleat 

frequency and orientation in appropriate coal core; 4) origin of CBM using C, O and H isotope analyses and 

hydrocarbon GC/MS analysis with thermal history and gas generation modeling; 5) other tests such as 

palynology, trace element characterization, and radiometric age dating may be performed on a few samples. 

6) If the wells are productive, The USGS may provide analyses of produced water to assess the potential 

environmental impact of produced water disposal from the coal zones. 

510
Devon SFS Operating, Inc., USGS and LGS will share in data interpretation and in report writing. All 

reports derived from the cooperative project will be published in the open literature (journal and proceeding 

articles) or as USGS or LGS open-file reports. Publication will commence no sooner than three years after 

the wells are drilled and the data is collected unless USGS, LGS, and Devon SFS Operating, Inc. agree to 

release the information sooner. 

Specific Tasks

USGS 

1) In consultation and with Devon SFS Operating, Inc. and the LGS, the USGS will conduct coal quality, 

coal petrography, vitrinite reflectance and geochemical analyses on approximately 16 one-foot coal core or 

selected coal interval cuttings samples collected from the two cored wells. The selected geochemical 

analyses will be appropriate to the sample characteristics and selected by consensus between Devon SFS 

Operating, Inc. and the USGS. The analyses include, but are not limited to: vitrinite reflectance, coal 

maceral composition, Rock-Eval pyrolysis, solvent extraction and GC/MS analysis of whole rock samples 

extracts as well as samples of produced and desorbed gases and liquids by isotopic and GC/MS methods. 

Several coal samples from each well will be selected for adsorption isotherms for CH4 and CO2 (CO2 is for 

USGS sequestration studies). Formation water samples, if available, will be chemically analyzed for total 

dissolved solids and elemental composition as well as oxygen and hydrogen isotopes. 

2) USGS personnel will assist with the interpretation of the data and in the preparation of reports and 

presentations. 

3) The USGS will be responsible for any lost or damaged USGS-owned sampling and field-testing 

equipment. 

4) The USGS will be responsible for the salaries, expenses, insurance and other costs needed to provide 2 

geologists and 2 technicians to the drill site. 

LGS Role

The LGS will provide 1) well-site support for sample collection and 2) will help to integrate the analytical 

results into regional subsurface maps and models that can be used to estimate and predict the CBM resources 

of the north-central Louisiana coal basin. With the USGS and Collaborator, LGS will provide subsurface 

maps that show the depth to Wilcox coal, the extent of the coal basin, number of coalbeds, the net coal 

thickness for the north-central Louisiana coal basin using among other data, the existing subsurface 

geophysical logs and seismic data. 

3) The LGS will be responsible for any lost or damaged LGS-owned sampling and field-testing equipment. 

4) The LGS will be responsible for the salaries, expenses, insurance and other costs needed to provide 1 

geologist at the drill site. 

The LGS in-kind contribution to this project is estimated to be $10,000.
