Attachment 2 - EIA UOG Resource Potential

Last updated: 3/31/2015

TDD Chapter TDD Table/Figure Tab Description

UOG TDD Chapter B, Section 4.2 Unconventional Oil 

and Gas Resource Potential N/A Raw EIA Data

EUR and TRR reported by EIA (obtained from Table 9.3 in 

SGE00486). This tab also includes ERG's calculation of new well 

potential for each formation or sub-formation reported by EIA.

UOG TDD Chapter B, Section 4.2 Unconventional Oil 

and Gas Resource Potential Table F-3 and F-4 Potential by Formation

EUR, TRR, and new well potential by UOG formation.

UOG TDD Chapter B, Section 4.2 Unconventional Oil 

and Gas Resource Potential Table B-3 Potential by Resource Type

EUR, TRR, and new well potential by resource type (shale gas, 

shale oil, tight gas, tight oil).

Sources are noted within each tab. Full citations are located in the References section of ERG's Data Compilation Memorandum for the Technical Development Document 

(TDD) for Proposed Effluent Limitations Guidelines and Standards for Oil and Gas Extraction (DCN SGE00693) .

Notes:

Except for column headings with "_ERG", data is presented here as reported in Table 9.3 of DCN SGE00988.

Column headings with "_ERG" indicate columns that ERG added for consolidation purposes.

The "Resource Type_Justification_ERG" column lists the references ERG used to assign each formation to a resource type (i.e., shale oil, shale gas, tight oil, tight gas).
