A Subsurface Stratigraphic Study of the Middle Atoka, Sebastian County, Arkansas
… to study the subsurface stratigraphy of the Middle Atoka in the Arkoma Basin of the western portion (Sebastian County) of Arkansas. The most significant sandstone units of the Middle Atoka in this area were determined to be two generally coarsening-upward sequences in the lower portion of the …

Stratigraphy and Depositional Environment of the Middle Atoka Formation, Central Arkoma Basin, Western Arkansas
… analysis of the subsurface stratigraphy of the middle Atoka Formation, Central Arkoma Basin, Western Arkansas. SP log, Gamma ray log, resistivity log and conductivity log provide valuable information to construct cross sections.</p> <p>The middle Atoka formation is composed of a succession of …

Diagenesis and Reservoir Characterization of the Pennsylvanian Middle Atoka Formation, Sebastian and Logan Counties, West-Central Arkansas
<p>The Middle Atoka Formation evolved from a stable passive margin during the early Pennsylvanian time to a rapidly subsiding basin, with the sedimentary fill thickening greatly southward during the middle Pennsylvanian time. The basin dips in north-south direction. An east-west anticlines and …

Stratigraphic and Structural Analysis of Middle Atoka Formation in Aetna Gas Field, Franklin, Johnson and Logan Counties, Arkansas
… basin. The defining feature of this basin is the Atoka Formation that was deposited in the early-middle Pennsylvanian. The Atoka is held equivalent to the tectonic and structural evolution of the basin. This study focuses on one of the many gas fields in the Arkoma Basin in Arkansas to assess the …

Early and Middle Atokan Lithostratigraphy and Reservoir Development, Northern Arkoma Basin, Northwestern Arkansas
… Dome to the north. Sedimentary rocks of early to middle Atokan age are present in the shallow subsurface at the northern margin of the Arkoma Basin in northwestern Arkansas. Sedimentary units of this time interval reflect basinal subsidence, and the transition of the Arkoma Basin from a passive …

Structural Cross Sections and Subsurface Maps of the Atoka Formation in the Northern Arkoma Basin, Western and Northwestern Arkansas
… is a short one in terms of latitude. The Atoka Formation in Arkansas comprises the bulk of the sediments in the Arkoma Basin. Three divisions of the Atoka Formation have been informally assigned as the Upper, Middle, and Lower based on differences in sedimentary response to tectonic …
