Appendix A – Documentation of Exploration Sources Emissions 
A.1. Drilling Rig Activities - Diesel Fuel Combustion

Year 2005 drilling rig engine emission estimates were generated using information obtained from the Texas 

Rairoad Commission (TRC) website, and by making several assumptions regarding drilling activity. Emissions

data are provided at the county-level using a bottom-up estimation approach as outlined below.

According to TRC, 9,754 wells were drilled in 2005, and drilled well counts are available by TRC District.

However, there is no compiled list of these wells on the TRC website. Additionally, fuel consumption for

drilling rigs were not available. To generate emissions, power output needed was calculated.

Approved oil and natural gas drilling permits were obtained for 2005 from TRC website. A total of 11,234

permits were retrieved. It is assumed that the drilling characteristics from the Approved permits are similar

to and overlap with the actual drilled wells. Table A.1-1 contains the data fields obtained from each permit.

Using the approved well permits, an "Approved Permitted to Active" adjustment factor was developed for each

TRC District. This factor will be applied to the final activity data prior to the emissions calculations. For

example, in District 1, 360 drilling permits were approved in 2005. According to the TRC website, drilling

activity occurred at 347 wells. Thus, an adjustment factor of 0.964 (347/364) was applied to drilling activity

data. Table A.1-2 presents the adjustment factors by TRC District

Horsepower by individual rigs were also not available. It was assumed that the horsepower for drilling rigs

is similar for certain depths. Rig Classifications and typical horsepower are presented in Table A.1-3. Each

Approved Permit was assigned a horsepower based on approved well depth.

6,500 to 11,500 1300

11,500 to 26,250 2000

26,250 to 32,800 3000

The emission factors for drilling rigs were taken from AP-42, and are presented in Table A.1-4. Based on the

approved well depths, all rigs were assumed to be greater than 600 horsepower.

VOC 0.29 grams/hp-hr

S = sulfur weight%; Assume 0.34% (3400 ppmv for each county)

Spud Date (date at which drilling began) and completed drilling date are available for most permits via the TRC

website. Using this information, number of drilling days can be computed. However, the effort to obtain this

information for over 11,000 permits would have been too resource-intensive. Thus, Drilling Profiles by county

and wellbore profile type were developed as surrogates. There were 430 unique county-wellbore profiles, and

the actual number of drilling days was obtained for the maximum well depth; these data are presented in 

Table A.1-5.

Using the applicable Drilling Profile, estimated drilling days can be calculated for each Approved well depth.

Equation 1. Active Drilling Well Emissions Equation:

Epoll_A,API = POAPI * EFpoll_A * CF

where,

Epoll_A,API = Emissions of pollutant A for API well number (tons)

POAPI = Power output for the American Petroleum Institute (API) well number (hp-hr)

EFpoll_A = Emission Factor of pollutant A (g/hp-hr)

CF = Conversion Factor from grams to tons (1.1025E-6 ton = 1 gram)

Equation 2. Power Output Equation

POAPI = WD * DPdays * Aadj * DH * HPclass 

DPdepth

where,

WD = Well depth (ft)

DPdays = Drilling profile days

Aadj = Approved Permitted to Actual activity adjustment factor (by TRC District)

DH = Drilling hours (assume 24 hours per day)

HPclass = Rig Classification Horsepower (hp)

DPdepth = Drilling profile well depth (ft)

Substituting Equation 2 into Equation 1 yields:

Epoll_A,API = WD * DPdays *Aadj * DH * HPclass * EFpoll_A * CF

An example calculation for Gonzales County, TX (FIPS = 48-177) is presented in Table A.1-6.

A.2. Mud Degassing Activities

Year 2005 mud degassing emission estimates were generated using information obtained from the Texas 

Rairoad Commission (TRC) website, and by making several assumptions regarding drilling activity. Emissions

data are provided at the county-level using a bottom-up estimation approach as outlined below.

According to the TRC, 9,754 wells were drilled in 2005, and drilled well counts are available by TRC District.

However, there is no compiled list of these wells on the TRC website.

Approved oil and natural gas drilling permits was obtained for 2005 from TRC website. A total of 11,234

permits were retrieved. It is assumed that the drilling characteristics from the Approved permits are similar

to and overlap with the actual drilled wells. Table A.1-1 contians the data fields obtained from each permit.

Table A.2-1. Data Fields Obtained from Approved Drilling Permits

Approved Date Well Number

Status Number TRC District

API Number County Name

Operator Name/Number Wellborne Profile

Lease Total Depth

Using the approved well permits, an "Approved Permitted to Active" adjustment factor was developed for each

TRC District. This factor will be applied to the final activity data prior to the emissions calculations. For

example, in District 1, 360 drilling permits were approved in 2005. According to the TRC website, drilling

activity occurred at 347 wells. Thus, an adjustment factor of 0.964 (347/364) was applied to drilling activity

data. Table A.1-2 presents the adjustment factors by TRC District

The total hydrocarbon (THC) emission factor for mud degassing was taken from the MMS Gulfwide Inventory 

(MMS, 2007), and is presented in Table A.2-3. It was assumed that the weight percent of the gassed VOCs

was 8.61% of the THC emissions. This calculated factor is also provided in Table A.2-3.

THC 881.84 lb/day

VOC 75.93 lb/day

Spud Date (date at which drilling began) and completed drilling date are available for most permits via the TRC

website. Using this information, number of drilling days can be computed. However, the effort to obtain this

information for over 11,000 permits would have been too resource-intensive. Thus, Drilling Profiles by county

and wellbore profile type were developed as surrogates. There were 430 unique county-wellbore profiles, and

the actual number of drilling days was obtained for the maximum well depth; these data are presented in 

Table A.2-4.

Using the applicable Drilling Profile, estimated drilling days can be calculated for each Approved

well depth.

Equation 1. Active Mud Degassing Well Emissions Equation:

EVOC,countyX = CDcountyX * EFVOC * CF

where,

EVOC,countyX = VOC Emissions for County X (tons)

CDcountyX = Calculated drilling days per county (days)

EFVOC = VOC Emission Factor (lb/day)

CF = Conversion Factor from lbs to tons (2000 lbs = 1 ton)

Equation 2. Calculated Drilling Days

CDcountyX = ∑(WDAPI * DPdays * Aadj/DPdepth)

where,

WDAPI = Well depth (ft)

DPdays = Drilling profile days

Aadj = Approved Permitted to Actual activity adjustment factor (by TRC District)

DPdepth = Drilling profile well depth (ft)

Substituting Equation 2 into Equation 1 yields:

EVOC,countyX = ∑(WDAPI * DPdays * Aadj/DPdepth) * EFVOC * CF

An example calculation for Zapata County, TX (FIPS = 48-505) is presented in Table A.2-5.

A.3. Well Completion Activities at Gas Wells - Flaring 

Year 2005 gas well completion emission estimates from flaring activities were generated using information

obtained from the Texas Railroad Commission (TRC), and by making several assumptions concerning gas 

well completion practices. 

According to the TRC, 7,197 gas wells were completed in 2005. However, there is no compiled list of these 

wells on the TRC website. The TRC website provides a summary of completed gas well counts by TRC 

District. Additional information on the well completion flowrate was needed to calculate emissions from flaring 

operations during the well completion testing.

Well completion information was obtained from The Drilling Observer, a third-party entity that compiles

Texas-specific drilling information from the TRC. Completion data from 5,156 wells were matched with 

approved drilling permit data to obtain the necessary data for calculating flaring emissions. Table A.3-1 

presents information that was provided for each gas well completion.

According to TRC Statewide Rule 32, flaring of gas during well completion can occur for 1 day after 10

days of venting. After that, a flaring permit is required for additional testing. Based on a Gas Research

Institute (GRI) report, this typically does not occur, as the flare testing lasts no more than 1 day (GRI, 1992).

Thus, the emission estimates reflect only 1 day of flaring for each well completion. It was also assumed that 

flaring occurs for 24 consecutive hours, although this practice may not be typical (GRI, 1992).

The volume flared per gas well completion was summed to the county-level. TRC District adjustment factors 

were developed to account for the differences in actual gas well completions (7,197) and gas well 

completions information from the Drilling Observer data set (5,156). The adjustments were made to the 

volume flared data prior to developing emission estimates, and these factors are presented Table A.3-2.

Emission factors for CO, NOx

, and VOC were applied to the adjusted county-level flaring volumes

to develop these emission estimates. It was assumed that H2S is not a component of the gas being

tested for completion, thus no SO2 emissions were created during flaring activities. Table A.3-3

presents the gas well completion flaring emission factors. It was also assumed that the VOC

weight percent of the total hydrocarbon (THC) is 8.61%. Thus, a VOC emission factor can be calculated:

A.4. Well Completion Activities at Oil Wells - Flaring 

Year 2005 oil well completion emission estimates from flaring activities were generated using information

obtained from the Texas Railroad Commission (TRC), and by making several assumptions concerning oil 

well completion practices. 

According to the TRC, 3,454 oil wells were completed in 2005. However, there is no compiled list of these 

wells on the TRC website. The TRC website provides a summary of completed gas well counts by TRC 

District. Additional information on the well completion flowrate was needed to calculate emissions from flaring 

operations during the well completion testing.

Well completion information was obtained from The Drilling Observer, a third-party entity that compiles

Texas-specific drilling information from the TRC. Completion data from 2,876 wells were matched with

approved drilling permit data to obtain the necessary data for calculating flaring emissions. Table A.4-1 

presents information that was provided for each gas well completion.

According to TRC Statewide Rule 32, flaring of gas (e.g., casinghead) during well completion can occur for 1

1 day after 10 days of venting. After that, a flaring permit is required for additional testing. Based on a Gas

Research Institute (GRI) report, this typically does not occur, as the flare testing lasts no more than 1 day.

(GRI, 1992). Thus, the emission estimates reflect only 1 day of flaring for each well completion. It was also 

assumed that flaring occurs for 24 consecutive hours, although this practice may not be typical (GRI, 1992).

The volume flared per oil well completion was summed to the county-level. TRC District adjustment factors 

were developed to account for the differences in actual oil well completions (3,454) and gas well 

completions information from the Drilling Observer data set (2,876). The adjustments were made to the 

volume flared data prior to developing emission estimates, and these factors are presented Table A.4-2.

Emission factors for CO, NOx

, and VOC were applied to the adjusted county-level flaring volumes

to develop these emission estimates. 

Table A.4-3 presents the oil well completion flaring emission factors. It was also assumed that the VOC 

weight percent of the total hydrocarbon (THC) is 33.2%. Thus, a VOC emission factor can be calculated:

Because casinghead gas typically contains hydrogen sulfide (H2S), SO2 emissions were assumed to be

created during flaring activities. It was assumed that the H2S component in the casinghead gas is 0.84%

by weight. Emission estimates for SO2 were developed using the Displacement Equation.

A.5. Well Completion Activities at Gas Wells - Venting 

Year 2005 gas well completion emission estimates from venting activities were generated using information

obtained from the Texas Railroad Commission (TRC), and by making several assumptions concerning gas 

well completion practices. 

According to the TRC, 7,197 gas wells were completed in 2005. However, there is no compiled list of these 

wells on the TRC website. The TRC website provides a summary of completed gas well counts by TRC 

District. Additional information on the well completion flowrate was needed to calculate emissions from 

venting operations during the well completion testing.

Well completion information was obtained from The Drilling Observer, a third-party entity that compiles

Texas-specific drilling information from the TRC. Completion data from 5,156 wells were matched with 

approved drilling permit data to obtain the necessary data for calculating venting emissions. Table A.5-1 

presents information that was provided for each gas well completion.

Table A.5-1. Gas Well Completion Information Obtained

The 24-hour casinghead gas flow potential test is the amount of casinghead gas that is vented from the oil

well during the completion process. This data is assumed to represent daily volume vented.

According to TRC Statewide Rule 32, venting of gas during well completion testing can occur up to 10 days.

Based on a Gas Research Institute (GRI) report, this typically does not occur, as venting lasts no more than

1 or 2 days (GRI, 1992). However, no information could be obtained on typical venting practices, thus

the emission estimates reflect 10 continuous days of venting for each gas well completion.

The volume vented per gas well completion was summed to the county-level. TRC District adjustment factors 

were developed to account for the differences in actual gas well completions (7,197) and gas well 

completions information from the Drilling Observer data set (5,156). The adjustments were made to the 

volume vented data prior to developing emission estimates, and these factors are presented Table A.5-2.

VOC emission estimates were developed using the Displacement Equation. It was assumed that the VOC

weight percent for the dry gas is 8.61%. All emission estimates were converted to tons.

Equation 1. Displacement Equation

Epoll_A,API = D * QAPI * CF1 * WT%VOC,ppm * MWVOC * CF2 *WCadj

C * CF1 * CF3

where,

D = Number of venting days (assume 10 days)

QAPI = Flow rate of the 24-hour potential test (Mscf/day)

WT%VOC,ppm = Weight percent of VOC in dry natural gas (8.61% = 86100 ppm)

MWVOC = Molecular weight of VOC in dry natural gas (1.545 lb/lb-mol)

CF1 = Conversion Factor from pounds to tons (2000 lb = 1 ton)

CF2 = Conversion Factor from Mscf to scf (1 Mscf = 1000 scf)

CF3 = Conversion Factor: 1 E-06 = 1 ppm

C = Ideal gas constant (379 scf/lb)

WCadj = Adjustment for actual number of Well Completions

A.6. Well Completion Activities at Oil Wells - Venting 

Year 2005 oil well completion emission estimates from venting activities were generated using information

obtained from the Texas Railroad Commission (TRC), and by making several assumptions concerning oil 

well completion practices. 

According to the TRC, 3,454 oil wells were completed in 2005. However, there is no compiled list of these 

wells on the TRC website. The TRC website provides a summary of completed oil well counts by TRC District.

Additional information on the well completion flowrate was needed to calculate emissions from venting 

operations during the well completion testing.

Well completion information was obtained from The Drilling Observer, a third-party entity that compiles

Texas-specific drilling information from the TRC. Completion data from 2,876 wells were matched with 

approved drilling permit data to obtain the necessary data for calculating venting emissions. Table A.6-1 

presents information that was provided for each oil well completion.

Table A.6-1. Oil Well Completion Information Obtained

API Number

Oil Lease Number

Operator 24-hour casinghead gas flow potential test

Lease

The 24-hour casinghead gas flow potential test is the amount of casinghead gas that is vented from the oil

well during the completion process. This data is assumed to represent daily volume vented.

According to TRC Statewide Rule 32, venting of gas during well completion testing can occur up to 10 days.

Based on a Gas Research Institute (GRI) report, this typically does not occur, as venting lasts no more than

1 or 2 days (GRI, 1992). However, no information could be obtained on typical venting practices, thus

the emission estimates reflect 10 continuous days of venting for each oil well completion.

The volume vented per oil well completion was summed to the county-level. TRC District adjustment factors 

were developed to account for the differences in actual oil well completions (3,454) and oil well 

completions information from the Drilling Observer data set (2,876). The adjustments were made to the 

volume vented data prior to developing emission estimates, and these factors are presented Table A.6-2.

VOC emission estimates were developed using the Displacement Equation. It was assumed that the VOC

weight percent for the casinghead gas is 33.2%. All emission estimates were converted to tons.

Equation 1. Displacement Equation

Epoll_A,API = D * QAPI * CF1 * WT%VOC,ppm * MWVOC * CF2 *WCadj

C * CF1 * CF3

where,

D = Number of venting days (assume 10 days)

QAPI = Flow rate of the 24-hour potential test (Mscf/day)

WT%VOC,ppm = Weight percent of VOC in casinghead gas (33.2% = 332,000 ppm)

MWVOC = Molecular weight of VOC in casinghead gas (7.687 lb/lb-mol)

CF1 = Conversion Factor from pounds to tons (2000 lb = 1 ton)

CF2 = Conversion Factor from Mscf to scf (1 Mscf = 1000 scf)

CF3 = Conversion Factor: 1 E-06 = 1 ppm

C = Ideal gas constant (379 scf/lb)

WCadj = Adjustment for actual number of Well Completions

A.7 - Gas Well Pneumatic Pumps

Year 2005 pneumatic pump VOC emission estimates from gas wells were generated using the 

displacement equation and making some assumptions on how pneumatic pumps operate. County level

counts of producing gas wells are provided on the Texas Railroad Commission (TRC) website. 

According to the TRC, there were 74,251 regular producing gas wells in 186 counties. It is assumed that

pneumatic pump activities are similar across all gas wells, and operate at a rate of 5 scf/hour.

For gas wells, it is assumed that as the dry natural gas is extracted through the well, some of the gas is

released via pneumatic pumps during normal operations. Additional assumptions include:

- the molecular weight of the dry natural gas is 17.963 lb/lb-mol.

- the VOC content of the natural gas was assumed to be 8.61%.

- the gas production wells were operating continuously

These assumptions, along with others are summarized in Table A.7-1.

Table A.7-1. Gas Well Pneumatic Pump Assumptions

Parameter Value Units Notes

Typical Pump Rate 5 scf/hr value from MMS Inventory

MW, dry natural gas 17.963 lb/lb-mol

VOC Wt % 8.61 %

# hours per year 8760 hours

Ideal Gas Constant 379 scf/lb-mol

Using the displacement equation, county-level VOC emission estimates can be generated. All emission

estimates were converted to tons.

 Evoc = n *Q * MW * Xvoc * 8760 *(1/C) * (1/2000) 

where,

Evoc = VOC emissions

n = # active gas wells

Q = Pneumatic Pump rate

MW = Molecular weight of the gas

Xvoc = VOC mass fraction of the gas

C = Ideal gas constant

Example calculation for Tarrant County, TX (FIPS = 48-439)

# gas producing wells, 2005 = 573

 Evoc = n *Q * MW * Xvoc * 8760 *(1/C) * (1/2000) 

 Evoc = 573 *5 * 17.963 * 0.0861* 8760 *(1/379) * (1/2000) 

 Evoc = 51.21 tons

A.8 - Oil Well Pneumatic Pumps

Year 2005 pneumatic pump VOC emission estimates from oil wells were generated using the 

displacement equation and making some assumptions on how pneumatic pumps operate. County level

counts of producing oil wells are provided on the Texas Railroad Commission (TRC) website. 

According to the TRC, there were 150,505 regular producing oil wells in 208 counties. It is assumed that

pneumatic pump activities are similar across all gas wells, and operate at a rate of 5 scf/hour.

For oil wells, it is assumed that as the casinghead gas is extracted through the well, some of the gas is

released via pneumatic pumps during normal operations. Additional assumptions include:

- the molecular weight of the casinghead gas is 23.149 lb/lb-mol.

- the VOC content of the casinghead gas was assumed to be 33.21%.

- the oil production wells were operating continuously

These assumptions, along with others are summarized in Table A.8-1.

Table A.8-1. Oil Well Pneumatic Pump Assumptions

Parameter Value Units Notes

Typical Pump Rate 5 scf/hr value from MMS Inventory

MW, dry natural gas 23.149 lb/lb-mol

VOC Wt % 33.2 %

# hours per year 8760 hours

Ideal Gas Constant 379 scf/lb-mol

Using the displacement equation, county-level VOC emission estimates can be generated. All emission

estimates were converted to tons.

 Evoc = n *Q * MW * Xvoc * 8760 *(1/C) * (1/2000) 

where,

Evoc = VOC emissions

n = # active oil wells

Q = Pneumatic Pump rate

MW = Molecular weight of the gas

Xvoc = VOC mass fraction of the gas

C = Ideal gas constant

Example calculation for Harris County, TX (FIPS = 48-201)

# oil producing wells, 2005 = 366

 Evoc = n *Q * MW * Xvoc * 8760 *(1/C) * (1/2000) 

 Evoc = 366 *5 * 23.149 * 0.332* 8760 *(1/379) * (1/2000) 

 Evoc = 162.54 tons

Table A.8-2 presents the county-level emission estimates.

Annual VOC emissions from gas wellheads were calculated by multiplying the total 2005 gas production 

(gas plus casinghead gas) in each Texas county (as obtained from the TRC) by the AP-42 (US EPA, 

2005) emission factor of 35.3 lb/MMscf (see Table B.2-1).

B.3 Compressor Engines 

Emissions from natural gas-fired compressor engines at oil and gas production facilities were calculated 

using the methodology employed in the Houston Advanced Research Council’s (HARC) study “Natural 

Gas Compressor Engine Survey and Engine NOX Emissions at Gas Production Facilities” (HARC, 2005). 

Based on that methodology, emission factors were calculated using the following equation: 

EFijk = F1i * F2j * Ci * Hj * EFjk * 1/2000 

Where: 

EFijk = Emission factor for county i, for engine type j, and pollutant k (tons/MSCF) 

F1i = Fraction of wells requiring compression in county i 

F2j = Fraction of compression load represented by engines of type j 

Ci = Compression requirements for county i (hp-hr/MSCF) 

Hj = Brake specific fuel consumption for engine type j (MMBtu/hp-hr) 

EFjk = Emission factor for engine type j, and pollutant k (lb/MMBtu) 

1/2000 = Conversion from lbs of emissions to tons of emissions 

Since the HARC study focused on eastern Texas, some of the factors in the above equation were applied 

to the rest of Texas on a county-by-county basis. 

Fraction of wells requiring compression (F1i) was estimated by HARC as the fraction of wells greater 

than one year old in three TRRC Districts (2, 3, and 6) as shown in Table B.3-1. ERG applied these 

fractions to the counties in each respective district and calculated an average fraction to apply to other 

counties:

Total 2,127 20,555 0.8965 

* Assumed to be the fraction of wells requiring compression. 

Fraction of compression load by engine type (F2j) was determined by the HARC report for eight 

engine types in three areas categorized by their attainment status, including attainment areas, the 

Houston nonattainment area, and the Dallas nonattainment area. Using these data, ERG calculated an 

average of the two nonattainment areas to apply to other nonttainment areas in Texas as shown in Table 

B.3-2:

Compression requirements by county (Ci) were calculated by HARC for TRRC Districts 2, 3, and 6 based 

on inlet and discharge pressures (see Table B.3-3). Those compression requirements were applied to 

counties in each respective TRRC District and an average was calculated for application to the rest of 

Texas:

B.4 Dehydrators 

Annual VOC emissions from glycol dehydrators were calculated by multiplying the total 2005 gas 

production (gas plus casinghead gas) in each Texas county (as obtained from the TRC) by the Wyoming 

Department of Environmental Quality (WYDEQ) emission factor of 75.3 lb/MMscf as presented in the 

Western Regional Air Partnership (WRAP) report on “Oil and Gas Emission Inventories for the Western 

States” (WRAP, 2005). The results of these calculations are presented in Table B.4-1.

B.5 Heater Treaters 

Annual emissions from heater treaters were calculated by multiplying the 2005 total of oil and condensate 

production (BBL) in each Texas county (as obtained from the TRC) by the Wyoming Department of 

Environmental Quality (WYDEQ) emission factors of 0.005 lb/BBL (NOX) and 0.001 lb/BBL (CO) as 

presented in the Western Regional Air Partnership (WRAP) report on “Oil and Gas Emission Inventories 

for the Western States” (WRAP, 2005). The results of these calculations are presented in Table B.5-1.

B.8 Oil and Condensate Loading 

Annual VOC emissions during oil and condensate loading were calculated using the following AP-42 (US 

EPA, 1995a) equation: 

LL = 12.46 * S * P * M / T 

Where: 

LL = Loading loss (lb/1,000 gal of liquid loaded) 

S = Saturation factor (based on type of loading operation) 

P = True vapor pressure of liquid loaded (psia) 

M = Molecular weight of tank vapors (lb/lb-mole) 

T = Temperature of bulk liquid loaded (oR) 

For the purposes of these emission estimates, ERG assumed the type of loading operation to be 

submerged loading with a dedicated vapor balance. The corresponding saturation factor (S) for this type 

of loading is 1.00. 

The true vapor pressures (P) and molecular weight of tank vapors (M) for oil and condensate were 

determined for each county based on the physical properties of similar substances. The properties of oil 

were assumed to be equivalent to “Crude Oil RVP 5” while condensate was assumed to be similar to 

“Gasoline RVP 7.” The physical properties of these substances as provided by AP-42 (US EPA, 2006) 

are summarized in Table B.8-1: 

Table B.8-1.

Crude oil RVP 5 50 2.3 2.8 3.4 4.0 

Gasoline RVP 7 68 2.9 3.5 4.3 5.2 

Since the true vapor pressures of these liquids are temperature-dependent, ERG performed a linear 

regression analysis on the data so that county-specific vapor pressures could be generated based on 

county-level temperature data. The linear equations relating the true vapor pressure (P) to temperature 

(T) in degrees Fahrenheit for each type of liquid are as follows: 

Oil (Crude oil RVP 5): P = 0.057 * T – 0.58 

Condensate (Gasoline RVP 7): P = 0.077 * T – 1.03 

The average annual temperature for each county in Texas (NCDC, 2007) was then applied to each 

equation to calculate the average annual true vapor pressure for oil and condensate, respectively. 

The temperature of the bulk liquid loaded (T) was assumed to be equal to the ambient temperature. ERG 

used the average annual temperature for each Texas county (NCDC, 2007) in oF and added 459.67 to 

obtain oR for use in the equation to determine loading losses. 

Once loading losses (lb/1000 gallons loaded) were determined for each county, ERG assumed that all oil 

and condensate produced in Texas would be loaded into truck or railcars and the loading losses were 

multiplied by the 2005 oil and condensate production for each county (as obtained from the TRC) to 

determine annual VOC emissions. These results are presented in Table B.8-2 and B.8-3 for oil and 

condensate, respectively.

B.9 Pump and Piping Component Fugitive Emissions 

Fugitive VOC emissions from pump and piping components were estimated using a methodology based 

around component-specific emission factors from the American Petroleum Institute (API, 1995). Because 

the API emission factors are component-specific, it was first necessary to estimate the number of pump 

and piping components at oil and gas production facilities in Texas. The Canandian Association of 

Petroleum Producers’ (CAPP) report on “CH4 and VOC Emissions from the Canadian Upstream Oil and 

Gas Industry – Volume 2” (CAPP, 1999) provided the information necessary to estimate the number of 

components at typical oil and gas production facilities. These data are shown in Tables B.9-1 and B.9-2 

for oil and gas production facilities, respectively:

Using these counts of equipment at typical oil and gas production facilities (assumed to be a 

group/central battery), an average of 2.8 wells per battery based on two independent surveys of Texas oil 

and gas batteries (HARC, 2005), (HARC, 2006b), and the number of oil and gas wellheads in each Texas 

county, ERG estimated the total number of pump and piping components in each Texas country as 

shown in Table B.9-3 and B.9-4 for oil and gas production, respectively. 
B.9-2 

Once the number of components was calculated, the API emission factors could be applied. These 

factors are shown in Table B.9-5:

Light Crude 8.66 E-03 6.38 E-02 1.68 E-02 7.00 E-02 3.97 E-01 

Gas Production 1.70 E-02 3.63 E-02 1.03 E-02 1.39 E-01 4.86 E-01 

“Others” includes instruments, loading arms, pressure relief valves, stuffing boxes, compressor seals, 

dump lever arms, and vents. 

Since the API factors are for total hydrocarbons (THC), they were multiplied by the average weight 

fraction of VOC in THC for onshore light crude (0.292) and onshore gas production (0.035) to determine 

average VOC emissions as shown in Tables B.9-3 and B.9-4. The estimated emissions from components 

in oil and gas service were then summed to show total VOC emissions from each component for oil and 

gas facilities

C.2. Texas State Waters Oil and Gas Platform Emission Estimates

Offshore oil and natural gas production and exploration emission estimates for platforms operating in Texas

state waters were developed at the county-level. The emission sources identified are similar to those

developed for the Mineral Management Services (MMS) Gulfwide emissions inventory (MMS, 2007). The

MMS inventory applies to emission sources operating in federal waters, defined as being 10 miles or greater 

off the Texas coast. It was assumed that the same general emission units operated in both federal and state

waters. Table C.2-1 presents the fourteen general source categories assumed to be operating in Texas state

waters.

The MMS emission inventory contains the same source categories; however, additional source categories

of amine units and losses from flashing were not included in the inventory of Texas state waters. In the 

2005 MMS inventory, there were less than 10 amine units operating in 2005, so these emission sources are

not typical on a platform. Additionally, it was assumed that flashing losses that typically occur during 

storage operations are included in the STO source category.

Since TCEQ does not maintain an emissions inventory of all state waters platforms, a model platform 

was developed. The assumption is that all platforms contain similar types and counts of equipment. Some

exceptions are noted:

1 Drilling operations do not typically occur on each platform. For this source category, the actual

number of drilling days from the Texas Railroad Commission (TRC) was obtained to calculate

fuel usage.

2 Mud degassing during drilling operations are assumed to have the same level of activity as the

drilling rig operations.

3 Most platforms operating in state waters were assumed to have pipelines for distribution of 

oil and/or condensate. However, a few platforms used barges for loading oil. Actual amounts

of oil loaded on barges were also obtained from TRC.

4 Storage tank emissions are based on actual barrels of oil or condensate produced.

Typical equipment counts were developed for the remaining platforms using the MMS inventory, and these.

data are presented in Table C.2-2.

Oil and gas production data were available at the lease block level from the TRC website. As stated before,

information on specific oil and gas platforms was not available. The approach for calculating per county

activity data is as follows:

1 Use the MMS data to calculate typical platform activity data. 

2 Multiply the typical platform activity data by the estimated number of operating platforms per county.

3 Apportion total emissions to the county-level by the county-level proportion of oil and gas 

production to total oil and gas production.

Table C-2.3 presents oil and gas production data retreived from TRC for 2005.

It is assumed that each oil lease represents one oil platform. It was also assumed that 6 gas leases represent 

one gas platform (TCEQ, 2000). Thus, a total of 17 oil platforms and 18 gas platforms were assumed to be 

operating in state waters.

Boiler/Heater natural gas fuel usage was calculated as follows:

Boiler/Heater natural gas fuel used per platform = operating hours * heat input rate * # units/platform

9,781.31 MMBTU/platform

Diesel fuel usage was calculated as follows:

Diesel fuel used/platform = operating hours * operating horsepower * fuel usage rate * # units/platform

(1,000,000 BTU/MMBTU)

13,033.79 MMBTU/platform

Natural Gas Engine fuel usage was calculated as follows:

NG Engine fuel used/platform = operating hours * operating horsepower * fuel usage rate * # units/platform

(1,000,000 BTU/MMBTU)

63,772.06 MMBTU/platform

Natural Gas Turbine fuel usage was calculated as follows:

NG Turbine fuel used/platform = operating hours * operating horsepower * fuel usage rate * # units/platform

(1,000,000 BTU/MMBTU)

593,086.62 MMBTU/platform

It was assumed that each platform contained 1 flare. It was also assumed that a continuous pilot light was

installed with each flare. Emissions from flaring occur from both the flaring operations and from the

continuous pilot light. The pilot fuel feed rate was assumed to be 2.28 MSCF/day, which was the default

feed rate used in the MMS emissions inventory. The average hours of operation for the 73 identified

pilot lights in the MMS inventory was 7,126 hours. Emissions are calculated as:

Fuel consumed, continuous pilot light = 365 days * Fuel Feed Rate * Average # operating hours

Drilling Rigs and Mud Degassing

Drilling rig and mud degassing activity are derived from the number of days drilling. According to the 

TRC website, sixteen platform locations in Texas state waters engaged in active drilling. Using the

spud date (the date when drilling commenced) and the completed drilling date, the actual number

of drilling days in 2005 were calculated. Rig classification and assigned horsepower were based

on total well depth. It was assumed that drilling and mud degassing activities occur 24 hours/day.

Power output required for the drilling rig was calculated using the following equation:

POAPI = DD * 24 hrs/day * HPclass 

where,

POAPI = Power output for API well number (hp-hr)

DD = Drilling days

HPclass = Rig Classification Horsepower (hp)

 which equates to 0.34%. The actual emission fatctor is 1.01*weight % of sulfur

B = It was assumed that the flares were smokeless, thus no PM emissions would occur

C = The emission factor was derived from MMS data. See table C.2-28.

Production-based emission factors for storage tanks were obtained from a HARC report (HARC, 2006b)

Barge loading of oil emission factors are calculated using a procedure in AP-42 (AP-42, pg.5.2-9).

Table C.2-30 presents the data inputs needed for developing the loading emission factor (AP-42, pg 7.1-63).

The emission factor equation is:

Loading EF, crude = (Ca +1.84*(0.44 * P - 0.42) * M * G * (1/T)) * VOC wt% *42 gal/bbl) * (1Mgal/1000gal)

where,

Ca = Arrival factor, any condition (lb/1000 gallons)

P = true vapor pressure of loaded crude oil (psia)

M = molecular weight of vapors (lb/lb-mole)

G = growth factor (dimensionless)

T = temperature of vapors (degrees R)

Equipment Control Information

The final piece of data need to calculate platform emissions were information on equipment controls found

on typical platforms. As stated earlier, platform emissions were available for 5 platforms. In some cases,

operating parameters for certain units were also provided, thereby calculating uncontrolled emissions 

estimates. A control efficiency percentage can be calculated using the reported and uncontrolled emissions.

Based on analysis of the uncontrolled and reported emissions, it was determined that only the natural gas

engines required a control system. No determination could be made on the non-combustion sources, as

the necessary information to calculate emissions were not provided. Table C.2-33 presents a summary of the

fuel used for each natural gas engine.

Emission estimates at the county-level for the various equipment types are presented in Table C.2-38. The general 

emissions equation is:

C.2-26
 Emissions = Activity Data * Emission Factor * (1-Control Efficiency/100) * Conversion Factor * (1 ton/2000 lb)

For Boilers/Heaters, the Conversion is equal to: 1 MMSCF/1050 MMBTU

For Flaring-pilot light activities, the Conversion Factor is equal to: 1 MMSCF/1000 MSCF 

For Flaring-flaring activities, the Conversion Factor is equal to: 1.05 MSCF/1 MMBTU

For Drilling Rig Engine activities, the Conversion Factor is equal to: 1 lb/453.54 grams

For the remaining source categories, the Conversion Factor is equal to: 1

All emission estimates are converted from lb to ton. 1 ton = 2000 lb
