Pennsylvania Coalbed Methane Wells Spreadsheet
Open-File Report OF 00–01
The Pennsylvania Bureau of Topographic and Geologic Survey (PaGS) introduces Open-File Report OF 00–01, a Microsoft Excel 97 spreadsheet compiled exclusively from wells associated with coalbed methane (CBM). It includes successful and unsuccessful accounts of CBM exploration and production data, and serendipitous encounters with the gas in the state from wells completed between 1938 and 1998. The report was updated in December 2000.
The 580-page (legal size) spreadsheet contains 228 rows and 61 columns and is intended to present an overall view of geographic and geologic data on CBM wells. The information was gathered from hard copy files from our Pittsburgh office, the Wells Information System (WIS), the Pennsylvania Internet Record Imaging System (PAIRIS), North American CBM Forums, literature (includes historical gas contents and reference to coal analyses), and personal communication with the operators when available.
For convenience, the status of the wells are grouped in the following general categories: 1) new (active, newly permitted, and not drilled or completed yet [have one year to complete well]; at various stages of exploration, extraction, or production; production status unknown; well record not received; or well data not entered in the WIS or spreadsheet); 2) producing (active, known local or commercial production); 3) nonproducing and/or inactive/nonproducing, inactive, and intend to be plugged (no production after one year or not equipped for production within 60 days after completion [this qualifies for a shut-in period of five years, but the operator must demonstrate future well utility]; low, short-term, or unknown production; and not plugged/intend to be plugged); 4) nonproducing, plugged, and/or waiting on plugging certificate; 5) dry and inactive/dry, inactive, and intend to be plugged (not plugged yet or intend to be plugged); 6) dry and plugged (not equipped for production within 60 days after completion and operator unable to demonstrate future well utility; little or no production); 7) dry and/or junked and/or plugged (same as for category 6); and 8) cancelled, expired, and/or not drilled (cancelled by the operator; expired, not drilled within one year of permit issuance). Some of the above include wells originally intended for CBM with limited or no gas production or only gas shows from coals, and reclassified as 9) storage, core, or shallow, conventional natural gas production. Specific code breakouts and explanations for quick reference are listed below.
- (C&/ND): cancelled and/or not drilled
- (DI): dry and inactive
- (DIIP): dry, inactive, intend to be plugged
- (DJP): dry, junked, plugged
- (DP): dry, plugged
- (E&/ND): expired and/or not drilled
- (JP): junked, plugged
- (N): new, active
- (NP&/I): nonproducing and/or inactive
- (NPCR): nonproducing, core
- (NPIIP): nonproducing, inactive, intend to be plugged
- (NPP): nonproducing and plugged
- (NPWPC): nonproducing and waiting on plugging certificate
- (PROD): local or commercial production, active
- (S): storage
Among the 61 columns are the following parameters: permit number (identification number), county, quadrangle, field, pool, latitude/longitude, year well completed, operator, farm name, township/municipality, producing formation/group, coal/other reservoir, thickness and depth to top of the coalbed, driller's log, interpreted stratigraphy (geologist's log), perforation zone and stimulation method, deepest producing target interval and depth, target/completion interval and depth, volume and depth of gas and water, rock pressure, annual gas and brine production, historical gas content data and coal analyses from literature where available (details on hard copy in Harrisburg office), total depth and formation/group, well classification, well type, production status, name of mine, type of geophysical log, status reported from LUMIS (former Bureau of Oil and Gas Management database), records noted that are on the WIS and PAIRIS, and other related information. For an explanation of geophysical well log abbreviations and selected coal and rock unit names and abbreviations, please see columns 58-61 of the spreadsheet.
NOTE: "Target" zones do not necessarily produce gas; they are intended zones of production.
Total well entries to date: 228 well permits with locations documenting gas from coal/original intent CBM/gob
Total wells producing on a commercial level (approximate): 72 (not all well records received to date for confirmation); according to David Bajek (personal communication, August 25, 2000) 64 from Belden and Blake Corporation, in Indiana (52) and Fayette Counties (12); 1 from Jesmar Energy, Inc. (Washington Co.); 2 from LAHD Energy, Inc. (Cambria Co.); 5 from CBE, Inc. (Greene Co.)
