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 stratigraphic and structural evolution that the strata in this particular field display. Aetna Gas Field extends from T. 8N. R. 27 W to T. 9 N, R. 27 W and T. 8 N, R. 26 W to 8N, R. 27. Geographically, Aetna field covers parts of Franklin, Johnson and Logan counties. It is one of the pioneer gas fields in the Arkoma Basin. First discovery of gas in Aetna Field was made in March 1928. The first three producing wells were completed in the upper Carpenter and middle Alma sands of the middle Atoka Formation. An analysis of structures and stratigraphy of the gas field through well log correlations reveal a combination trap for the gas. Using IHS Petra, stratigraphic correlations were performed on 49 wells in 10 cross sections. The wells selected were sorted by several criteria. Gamma ray logs were given priority. Stratigraphic tops were determined for correlation purposes. The stratigraphic tops were picked and correlated. The middle Atoka Formation was addressed exclusively for the purpose of this study. Structural analysis indicates an arch-and-trough setting that led to gas accumulation in this field. The stratigraphic analysis confirms a thickening to the south following the general southern thickening trend of Atoka Formation in the Arkoma Basin.

This book was released on 2012-12-06 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 32 (thesis year 1987) a total of 12,483 theses titles from 22 Canadian and 176 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 32 reports theses submitted in 1987, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

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 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
