The Bureau of Economic Geology is conducting a multiyear reservoir characterization and resource recovery analysis of Texas State Lands that indicates that proved oil reserves (that is, oil that will be produced using currently deployed technology) total only 270 MMSTB. This figure compares with the 3.43 BSTB of oil that is projected to remain in the ground at reservoir abandonment, 1.6 BSTB; of which is mobile oil. The amount of mobile oil that will be foregone unless advanced geological and engineering technology continues to be applied to State Lands reservoirs is substantial. A similar picture emerges for natural gas in Texas State Lands. Cumulative gas production is 10 Tcf. The amount of natural gas remaining in the largest State Lands gas reservoirs, however, is estimated to be another 10 Tcf. 'Me amount of natural gas projected to remain unrecovered at reservoir abandonment under currently deployed technology thus equals the amount of gas produced to date. Clearly, with regard to in-place volumes of oil and gas, Texas State Lands reservoirs are nowhere near depletion.

The State of Texas advanced resource recovery (Project STARR) initiative is designed to capture a substantial portion of that large volume of unrecovered oil and gas remaining in State Lands fields. To identify the residency of the remaining State Lands oil and gas resource base, Project STARR's approach has been to define and deploy on a field-by-field basis, in conjunction with field operators, advanced resource recovery strategies to ensure maximal recovery efficiency. Twelve State Lands fields, comprising eight West Texas and four Gulf Coast fields, are undergoing characterization and extended development side by side with Texas operators.
