"What's New" in the 5/1/2018 Version of the Oil and Gas Well Database Since the Previous Release (4/20/2017)

Since the previous release of the database, "current" well completions (i.e., new well completions, deepenings, workovers, etc.) were added to the database from weekly batches received from the State regulatory authority for oil and gas and from direct submissions to WVGES from operators through April 13, 2018. There were no changes in the structure of any of the data tables this year. A total of more than 134,000 records were added or updated in all nine tables in this release of the database, as a result of ongoing work in the agency. The entire database contains more than 3,250,000 records.

Among the major changes in this version of the database are:

LOCATIONS:

More than 1,000 well location records were added or modified in this version of the database.

BOTTOMHOLE LOCATIONS:

More than 1,600 records were added (or modified) for proposed (or actually drilled) bottomhole locations for deviated/horizontal wells. In the case where an "as drilled" bottomhole location was submitted, the "as proposed" bottomhole location remains in the database.

OWNERS/COMPLETIONS:

More than 38,800 records have been added or modified since the previous release of the database, including thousands of records updated in the 30000-series of pre-1929 wells in the State, a comprehensive review of farm names, well numbers, and company numbers in several counties in the State, correction of some spud date/completion date issues, the addition of estimated formation pressures, and other ongoing validations of data in the database.

PAYS/SHOWS/WATER:

More than 15,800 data records were added or updated, for both recently completed wells and as updates to wells already in the database. Many of the new records were added from recently completed horizontal/deviated wells which have a large number of perforation zones. Records were also added from an ongoing comprehensive review of the 30000-series older wells in the State and from editing/review of stratigraphic units assigned to pay/show/horizon zones in this table, especially Devonian shale units.

STRATIGRAPHY:

More than 14,800 records were added or edited, including both current well completions and considerable updates/additions to wells already in the database. Records were also added from an ongoing comprehensive review of the 30000-series older wells in the State. Interpretations of several Upper Devonian stratigraphic units have been refined.

PRODUCTION:

Monthly and annual well production data for 2016 were added to the database for 61,423 wells. There are more than 1,648,000 production records in the database, from 1979 to 2016.

PLUG:

More than 270 plugging records were added or updated since the previous release.

MECHANICAL LOG CATALOG (MLC):

More than 300 records were added to or modified in this table. The scanned images themselves are not included in this database release; they are available for free download from the Geological Survey's website at http://www.wvgs.wvnet.edu/www/news/dataslgs.htm. Information about the e-logs in the WVGES Log Library is included in this database so that users can search and query for available e-logs meeting user needs.

WELL SAMPLES AND CORES (WSC):

25 records were added to the database or updated since the previous release of the database; most of these were for newly-acquired cores and cuttings.
