Changes To Updated Oil and Gas Well Data


Changes in the 8/3/05 Version of the Database Publication Since the Previous Release (1/31/05)

In addition to the addition of a few thousand new data records, many thousands of changes/modifications have been made to records in the database since the previous release. These modifications should improve the correctness of the data and its efficiency in operating within user software. A summary of these modifications is given below.

LOCATIONS: the values of well coordinate fields previously recorded as zero have been changed to "null"; a new variation of the file (WV_LOCS_NUMCOORDS.ASC) has been added in which double quotes around four data fields (LatDD, LonDD, UTME, and UTMN) have been removed.
OWNERS/COMPLETIONS: the length of the "Lease Number" field has been changed from vchar(6) to vchar(15); several "Operator" names have been updated to better reflect current data; where previously recorded as zero, the value of the "Total Depth" field has been changed to "null".
PAYS/SHOWS/WATER: where previously recorded as zero, the value of the "Top of Interval" field has been changed to "null"; the "Before" field for all Water records has been changed to "null".
PRODUCTION: several operator names have been updated to reflect current data; the 2004 monthly and annual production data are NOT included in this update.
MECHANICAL LOG CATALOG: the "Scanned Logs" field has been updated (with "Y" for "Yes") to reflect the availability of a digital scanned log (TIFF) for applicable wells in Hancock, Hardy, and Wyoming counties; updating this field is a work-in-progress, and many more scanned log files are actually available than are currently reflected in the database.
