To most efficiently estimate oil and gas reserves for the State of Colorado, a county-by-county analysis was undertaken. This report is the sixth in a series of oil and gas reserve investigations undertaken for those counties in which oil and/or gas was being produced at that time. 32 pages. Digital PDF download. OF-84-08D

Baca County, located in the southeastern corner of Colorado. The eastern edge of this county is part of the Hugoton Embayment. In this county, oil and/or gas are produced from, in descending order of age, the Red Cave (Lyons) Sandstone, Wabaunsee Carbonate, Topeka Carbonate, Lansing Limestone, Morrowan Sandstone, and Keyes Sandstone. There are 10 fields considered active producers as of September 30, 1983. Of these, 3 are classified as oil fields (based on cumulative gas-oil ratio (GOR) of 15:1).

Production decline curves are plotted for each currently producing horizon within each field (field-horizon). There are 17 production decline curves plotted, one for each field-horizon. Decline rates were calculated where there were sufficient production histories. Estimated oil reserves for Baca County totaled 1,064,172 barrels. Estimated gas reserves for Baca County totaled 32,556,964 MCF. Note that the gas reserve calculations are based on a 20-year projection, therefore they do not account for gas production after the year 2002. These figures also do not account for production increases due to secondary and/or tertiary recovery not already in progress, or account for undiscovered reserves, nor do they reflect changes in economics and demand.
