SUBJECT : Hydraulically Fractured Oil Well Completions

Eastern Research Group, Inc. (ERG) is currently under cont ract with EC/R Incorporated to provide

technical support under EC/R Work Assignment #1

- 11 with U.S. EPA. This memorandum describes ERG’s

findings relative to Task 2 of the support effort. Specifically, under this task ERG:



### • Identified wells which were hydraulically fractured in 2011;



### • Determined which of the hydraulically fractured wells completed in 2011 were oil wells;



### • Estimated daily associated gas production from the hydraulically fractured oil wells; and



### • Provided a summary of this informat ion at the national and county level (in Excel spreadsheet

format).

Wells Hydraulically Fractured in 2011

Starting with the most recent analysis and files delivered by ERG to the U.S. EPA Office of Compliance,

ERG queried DI Desktop, a production data base maintained by DrillingInfo, Inc.

covering U.S. oil and natural gas wells, to identify hydraulically fractured oil and gas well completions

performed in 2011. This was accomplished using a two

- step process:



### • Identification of wells completed in 201 1;



### • Identification of wells completed using hydraulic fracturing.

Wells completed in 2011 were identified as those wells meeting one of the following criteria: DRAFT MEMORANDUMA

- 3



### • The DI Desktop data for the well indicated it was completed in 2011; or



### • The DI Desktop d ata for the well indicated the well 1 st produced in 2011.

While the DI Desktop database is fairly comprehensive in its geographic and temporal coverage of

production data, completion date information can lag behind by a year or more afterwards and is no t

universally available for all areas of the country. Therefore, the list of wells with explicit well completion

dates of 2011 was supplemented with those wells having a date (month) of 1 st production of either gas

or oil in 2011. This methodology is con sistent with the methodology used to estimate well completions

in the “Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990

– 2011 (April 12, 2013)”.

Using this approach, 39,262 conventional and unconventional well completions were identified for 2011.

Once the population of wells completed in 2011 was identified, hydraulically fractured wells were

identified as those wells meeting either of the following:



### • Wells completed in a coalbed methane, tight, or shale formation as determined using the DOE

EIA formation type crosswalk; or



### • Wells identified in the DI Desktop database as horizontal wells.

The DOE EIA formation type crosswalk used in this analysis may be found in Attachment A. This

methodology is consistent with the methodology used to identify the number of hydraulically fractured

well completions in the “Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990

– 2011 (April 12,

2013)”.

Using this approach, 15,979 hydraulically fractured (or unconventional) well completions were i dentified

for 2011.

Oil Wells Hydraulically Fractured in 2011

Once the population of hydraulically fractured wells completed in 2011 was identified, each well was

then classified as either an oil well or a gas well. Gas wells were defined as those we lls with an average

gas to liquids ratio greater than or equal to 12,500 standard cubic feet per barrel over the lifetime of the

well, and oil wells were defined as those wells with an average gas to liquids ratio less than 12,500

standard cubic feet per b arrel over the lifetime of the well. Note that the “liquids” quantity used in this

analysis does not include produced water. This methodology is consistent with the gas

‐ oil ratio

methodology used in the 2012 Oil and Natural Gas Sector NSPS development.

Using this approach, 6,169 hydraulically fractured (or unconventional) oil well completions were

identified for 2011.A

- 4

Daily Gas Production of Oil Wells Hydraulically Fractured in 2011

Once the population of hydraulically fractured oil wells complete d in 2011 was identified, the average

daily gas production for each well was calculated based on the cumulative gas production from each

well during its first year of production. This information was then averaged at the county

- level, as well

as at the na tional level. Nationally, the average daily gas production at an oil well that was hydraulically

fractured in 2011 was 152 MCF.

Summary Information

Table 1 below presents a state

- level summary of the derived information on hydraulically fractured oil

wells completed in 2011. Attachment B contains the same information at the county and national level.

Observations

The analysis conducted under this task was performed in accordance with the procedures described

above. With respect to qualitative observations made while implementing these procedures, ERG notes

the fo llowing:A

- 5



### • In some instances, the date (month) of 1 st production only included oil production, with no

corresponding gas production recorded for that month;



### • In some instances, there were months within the 1 st year of production where there was no

produc tion (of oil, gas, or both) recorded for the well;



### • For 415 oil wells hydraulically fractured and completed in 2011, there was no gas production

reported for the well during the 1 st year of production.

The net effect of these situations is that the aver age daily gas production values may be skewed low, for

example, due to a well being shut in for some period of time after initially being brought into

production.

In the case of the 415 wells where there was no gas production reported for the well durin g the 1 st year

of production, summary data is presented in Attachment B excluding these records. This data is

reflected in the summary sheets indicating “WITHOUT ZERO”. The effect of this differentiation is easily

seen in the “UNCONV_OIL_NATIONWIDE” shee t, which shows an average daily gas production of 152

(MCF/day) for all records, and an average daily gas production of 189 (MCF/day) when including only

those records with some gas production.A
