A Subsurface Stratigraphic Study of the Middle Atoka, Sebastian County, Arkansas
… 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
… 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 shale and …

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 …

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 …

Sedimentary Petrology of the Hartshorne Formation, Southeastern Arkoma Basin, Arkansas
… the Stanley Formation (Mississippian) and the Atoka Formation (Pennsylvanian) of the frontal Ouachita Mountains contain abundant lithic fragments (Atoka) and feldspar (Stanley). The lithic composition of the Stanley and the Atoka is consistent with the lithic composition of the Hartshorne. This …

Early and Middle Atokan Lithostratigraphy and Reservoir Development, Northern Arkoma Basin, Northwestern Arkansas
… 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 margin …

Structure and Stratigraphy of a Complex Anticlinal Feature, Backbone Anticline, Arkoma Basin, Arkansas
… units from the middle and upper part of the Atoka Formation. A recent road cut in southern Sebastian County, Arkansas exposes a complete and continuous section of more than 600 feet in thickness through an upper Atoka sandstone unit along the Backbone anticline. </p> <p>A subsurface …

Framework Grain Composition and Texture of the Wedington Sandstone Member, Fayetteville Shale, as a Provenance and Sediment Dispersal Indicator for Clastic Depositional Systems Across the Northern Arkansas Structural Platform During the Late Mississippian
… the Batesville Sandstone (older) and the Basal Atoka-Spiro Sandstone (younger) has addressed three questions: 1) Is there similarity in sediment provenance for the three sandstones? 2) Do these three sandstone units have a similar sediment dispersal vector? 3) What are likely sediment source …

RESOLUTION OF SUB-SEISMIC RESERVOIRS BY THE APPLICATION OF SPECTRAL DECOMPOSITION AND SPECTRAL INVERSION METHODS IN BOONSVILLE FIELD, NORTH CENTRAL TEXAS.
… patterns created by thin layering within Atoka conglomerate that forms the producing unit in this field. The Atokan conglomerate is a case of thin bed reservoir with discontinuous beds that depict seismic resolution below the typical Widess limit, making bed thickness estimation using …

Petrology and Weathering Environment of Sub-unconformity Limestone unit: The Kessler Limestone member of the Bloyd Formation, Morrowan (Pennsylvanian) Northwest Arkansas
… and overlain by the Trace Creek Shale of the Atoka Formation. The contact between the Kessler Limestone Member and the Trace Creek is a regional unconformity in the midcontinent, marked by a manganese-enriched crust filled with various nodules and concretions. Methods used in this study began …

Reservoir Characterization and Depositional System of the Atokan Grant Sand, Fort Worth Basin, Texas
<p>The Atokan Grant Sands are a tight gas sand play that would add new reserves to the Fort Worth Basin. The Fort Worth Basin is located in north-central Texas just west of Dallas, Texas. Within the basin, the study area consists of Denton, Wise, Tarrant, and Parker Counties in Texas. The basin is …
