A STUDY OF GEOLOGICAL AND PETROPHYSICAL PROPERTIES OF COTTON VALLEY SANDSTONES IN EAST TEXAS AND NORTH LOUISIANA - Available in RAPID
Core Laboratories completed a study of Cotton Valley Sandstones in east Texas and north Louisiana to identify and provide data on the spectrum of Cotton Valley reservoir rock types to be applied in the discrimination of commercially viable reservoirs. The study defines the rock properties which control the preservation and/or development of pore space, delineates rock types and their associated pore structure as they relate to reservoir quality, and integrates rock petrophysical properties and rock type information with well log evaluation to develop criteria for the recognition of pay intervals.
The study consists of data generated on sixty (60) rotary sidewall sandstone samples from 12 wells located in Rusk, Panola, Harrison and Cass Counties, Texas and Bienville Parish, Louisiana. These wells represent nine (9) separate fields and all tested gas from one or more intervals. In addition to the petrographic and advanced rock property data, composite data files were created for measured and calculated well log curves covering approximately 10,000 feet of wellbore.
