Book excerpt: The Mansfield sand is an informally named member of the Pennsylvanian Atoka Formation in Arkansas. Once a productive gas reservoir, the Mansfield is situated in a double plunging anticline in the southern portion of the Arkoma Basin. The formation is internally composed of sandstone units ranging in thickness from tens of feet to over a hundred feet interbedded with shale units ranging in thickness from several tens of feet to hundreds of feet. Previous studies have focused on the stratigraphy of the lower and middle Atoka. A detailed subsurface study of the stratigraphic framework of the Mansfield sand was conducted using conventional lithostratigraphy and sequence stratigraphy. Four progradational parasequences have been identified within a highstand systems tract. Deposition of the Mansfield occurred in a deltaic environment on a sandy, fluvial or wave dominated shoreline.

Book excerpt: Wire line logs are widely used in 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. The middle Atoka formation is composed of a succession of shale and sandstone alternations with thickness reaching approximately 3000 feet in the study area. It contains several sandstone units which include Morris, Tackett, Areci, Bynum, Casey and Dunn "A" separated by shale intervals. The purpose of this study is to identify these units and predict sequence stratigraphy and depositional environment by constructing cross-sections, observing wireline logs and associating previous research. Several isopach maps are made, explaining the development of sandstone in target units such as Tackett and Casey. The sequence stratigraphy of the middle Atoka formation is mainly composed of transgressive systems tracts and part of a highstands systems tract. The intervals indicate successive sea-level cycles associated transgression and regression from shallow marine to shoreface. The middle Atoka formation has been proved as a significant exploration target since 1950's. In order to understand geologic setting and find potential reservoirs within the Arkoma basin, it is vital to comprehend the sequence development and depositional environment of the intervals within the middle Atoka.

This book was released on 2018 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arkoma Basin is one of several peripheral foreland basins situated on the front of the Ouachita orogenic fold and thrust belt. The transition from the foredeep to the Ozark Plateaus 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 processes that occurred during the formation and subsidence of the Arkoma Basin. In the Arkansas portion of the Arkoma Basin, the lower Atoka marks the onset of tectonic subsidence in between the Mulberry and the Cass Fault systems and displays a maximum of almost 1,000 feet of thickening in the study area. The middle Atoka in the same area gains a maximum of 4,000 feet of sediment. The upper Atoka achieves a maximum thickness of 1,800 feet. Entrapment of hydrocarbons within the Atoka Formation in the Arkoma Basin has led many oil and gas companies to penetrate and log the formation with electric, gamma ray and other mechanical logs while exploring for natural gas. This study uses these raster logs to provide a variety of maps and cross sections that illustrate the coastal systems of the lower and upper Atoka Formation and aid in the interpretation of the sedimentary response of the three Atoka divisions with respect to structural timing and sedimentology. With the subsurface maps and cross sections, a more synthesized version of the Atoka Formation in the northern Arkoma Basin of western version is produced.

This book was released on 2014 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arkoma Basin of Arkansas and Oklahoma formed in the Ouachita foreland during the late Mississippian and Pennsylvanian periods (about 290- to 330 million years ago). The basin developed in response to convergent tectonic boundaries that closed obliquely from west to east associated with Ouachita orogenic event. The Backbone anticline in the northern Arkoma Basin is a prominent product of this convergence, and represents the first major component of this study. The structure is asymmetric with beds on the southern limb dipping steeply to the south. It is also expressed topographically as a prominent ridge that trends eastward from the Oklahoma-Arkansas border approximately 30 miles. The ridge is bounded on the northern side by a steeply dipping normal fault with most of the sedimentary exposure occupying a position on the southern hanging wall of the structure. Strata involved in the structure are sandstone and shale 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. A subsurface stratigraphic study of the middle of the Backbone anticline was also conducted. Several normal and some reverse faults were noted from cross-sections of the subsurface using IHS PETRARTM software program. The upper 5400 feet of the Atoka Formation includes intervals from the middle and upper part of the formation. This interval extending from the Casey Sand to the Upper Alma Formation was examined by means of three cross-sections prepared from wire line logs to determine the role of faulting in the sedimentary section

This book was released on 2018 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arkoma Basin is a Carboniferous peripheral foreland basin creating a structural depression covering an approximate area of 33,800 miles2 that extends through east-central Oklahoma and west-central Arkansas. The entire basin fill includes Pre-Mississippian carbonate shelf deposits, Mississippian marine carbonates and black shales, and Pennsylvanian mixed carbonated/clastic and shore zone/deltaic deposits. The Lower Atoka formation (Pennsylvanian) occurs in outcrop along the southern Boston Mountain Plateau in northern Arkansas and extends into the subsurface of the Arkoma Basin over an area of 2,300 miles2. The Lower Atoka ranges from 600 to 1500 feet in thickness and represents a cyclic succession of stacked shelf to shore zone/deltaic deposits recording a single 3rd order (1-10 m.y.) Vail/Exxon depositional sequence. It was deposited across a broad, tectonically stable platform along the southern margin of Laurasia just before its collision with the Gondwana and the formation of Pangea at the end of the Paleozoic. Tectonic influences meant that it was not a 100% stable platform during the Lower Atoka deposition. This affected the deposition of all the sequences in the Lower Atoka. Topographic relief on preceding deposition also helped create areas of accommodation space filled by offset, compensation bedding. Finally, subsidence on a passive margin has been argued to be up to almost 4 km. This helps explain the "long distance" shoreline shifts and cyclicity in the current time of deposition. This means that these 4th to 5th order cycles (10's to 100's k.y.) may reflect glacio eustacy and sediment supply and can be correlated across the entire area or a very large area. In addition, there appears to be a tectonic over print that influences onlap edges that define northern limits and areas of bypass and nondeposition.

This book was released on 2019 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The east-to-west oriented Arkoma Basin is a peripheral foreland basin or depositional trough that developed during the Carboniferous Period. This formation covers an aerial extent of approximately 33,800 square miles and spans from west-central Arkansas into southeastern Oklahoma (McGilvery, Manger, and Zachry, 2016; Perry, 1995). The Atoka Formation, deposited during the early Pennsylvanian, is the largest Paleozoic formation by aerial extent in the state of Arkansas and is located within and comprises the bulk of Arkoma Basin sediments (McFarland, 2004; Nance, 2018). This formation has been informally divided into three divisions, the lower, middle, and upper, based on their stratigraphic response to differing tectonic processes. A tectonostratigraphic interpretation was made for each division of the Atoka Formation using high resolution cross sections; correlated using well log, seismic, and surface data. Five condensed regional transects were constructed that aided in the development of a cross section "grid" meant to represent the deep marine to shallow marine depositional hinge lines. Each of the three Atoka divisions have a different dominant depositional force. The Lower Atoka deposition was dominated by eustasy, and with sediment supply from the start of Arkoma Basin tectonics, the middle division was dominated by tectonic subsidence and the upper was dominated by sediment supply. The transition between the Atoka divisions and the magnitude of migration between each deep marine hinge line indicates the progradation of the Upper Atoka depositional cycles occurred more rapidly than the retrogradation of the Middle Atoka. The maximum flooding of the formation occurred within the Middle Atoka's uppermost informal member, the Morris Member. The Lower Atoka was deposited on an extensive tectonically stable structural platform, which is supported by no lithostratigraphic transition to deep marine deposits within this project's study area. The deep marine deposition is characterized by shales encapsulating tumultuously distributed and isolated sandstone complexes. These sandstone complexes are not correlated to the shallow marine sandstones by anything but a condensed geologic timeline.
