Stratigraphy, Depositional Environments, Petrology, Diagenesis, and Hydrocarbon Maturation Related to the Red Fork - - Sandstone in North-central Oklahoma

Abstract

This study focuses on the stratigraphy, depositional environments, petrological characteristics, diagenetic sequences, and hydrocarbon maturation related to the Red Fork sandstone in north-central Oklahoma. Approximately 700 electric logs were used to construct nine regional cross sections and four diagnostic subsuface maps. These maps and cross sections were used to delineate the stratigraphy of the Red Fork sandstone. Depositional environment(s) were interpreted based upon vertical and lateral relationships generated from core descriptions�, cross sections, log, net sand, and isopach maps. Petrologic and diagenetic analysis were established upon detailed thin section examination, bulk and extracted X-ray diffraction� analysis, and scanning electron microscopy of the cores. Burial history and hydrocarbon maturation interpretations were based upon the depositional and tectonic history of the region, and vitrinite reflectance values obtained from the cores.
