STARR Field Studies 1995-present [PDF]


STARR reservoir characterization studies result in step-out wells, well deepening, recompletions, targeted infill drilling, injection-profile modification, waterflood optimization, and drilling of untested deeper targets in producing fields.

Fields characterized by STARR are widely distributed in Texas and include reservoirs in a variety of stratigraphic units (see map below). Areas in Texas represented by sandstone reservoirs are located in the Gulf Coast and in the East Texas Basin, the Permian Basin in West Texas, and the Anadarko Basin in the Texas Panhandle.

Carbonate reservoirs include the Marble Falls Formation, Ranger Limestone, and Caddo Formation in North Texas, and the Glorieta Formation in West Texas. Unconventional reservoirs in southwest Texas (Austin Chalk and Eagle Ford Formation) and the Permian Basin (Spraberry and Wolfcamp Formations) round out the remainder of the field studies.
