Subsurface analysis of the Spencer Consolidated Oil Field, Posey County, IndianaFisher, David M. January 1981 (has links)
In this paper, I will determine the subsurface structure of the Spencer Consolidated Oil Field occupying Sections 1, 2, 11-15, 22, 26, and 27 of Township 8 South, Range 14 West, Posey County, Indiana (Uniontown 7 1/2" Quadrangle).Oil production in the Spencer Consolidated is from three principal formations. These are, in descending stratigraphic order, the Renault Formation, Aux Vases Sandstone, and Ste. Genevieve Limestone, in which the producing zones are referred to as either McClosky sands or oolitic bodies. Mapping the configuration of the oilbearing rocks and defining the distribution of these rocks will be my main concern.Structure contour maps of these three formations were prepared, as were isopach maps of the base of the lower Renault limestone and the Aux Vases Sandstone. There are insufficient data points defining the Ste. Genevieve.For the possible recovery of new hydrocarbons within the Spencer Consolidated and the exploration of existing traps, electric log correlation sections, both transverse and parallel to the surrounding faults, were made. For reliability and consistency, only those wells with electric logs were used.

Integrating depositional facies and sequence stratigraphy in characterizing carbonate reservoirs: Mississippian limestone, western KansasMartin, Keithan January 1900 (has links)
Master of Science / Geology / Matthew W. Totten / The Mississippian-aged St. Louis Limestone of Western Kansas is a carbonate resource play that has been producing oil, gas, and natural gas liquids (NGL) for over 50 years. The Mississippian Limestone is made up of heterogeneous limestones with interbedded layers of porous and non-porous units, abrupt facies changes, and diagenetic alterations. These factors combine to characterize the St. Louis Limestone's internal complexity, which complicates hydrocarbon exploration. This study focuses on improving the understanding of the geometry, distribution, and continuity of depositional facies within Kearny County, Kansas. Petrophysical analysis of a suite of geophysical logs integrated with core provided the basis for establishing facies successions, determining vertical stacking patterns within a sequence stratigraphic framework, and correlating areas of high porosity with a respective facies. The following depositional facies were identified; 1) porous ooid grainstone, 2) highly-cemented ooid grainstone, 3) quartz-carbonate grainstone, 4) peloidal grainstone, 5) micritic mudstone, and the 6) skeletal wackestone/packstone. The porous ooid grainstone is the chief reservoir facies, with log-derived porosity measurements between four and eighteen percent. In areas without available core, depositional facies were predicted and modeled using a neural network analysis tool (Kipling2.xla). Values derived from the evaluated core intervals and their respective geophysical logs served as the framework for the neural network model. This study illustrates the advantages of correlating depositional facies with reservoir quality and correlating those specific facies to geophysical logs, ultimately to create a greater understanding of the reservoir quality and potential within the St. Louis Limestone of western Kansas.

The Social Costs of War: Investigating the Relationship between Warfare and Intragroup Violence during the Mississippian Period of the Central Illinois ValleyJanuary 2015 (has links)
abstract: War exacts a great social cost, not only upon its direct participants, but also upon the lives of the friends, family, and community of those who experience it. This cost is particularly evident in the increased frequencies of aggressive behaviors, including homicide, assault, and domestic violence, enacted by Western military veterans with posttraumatic stress disorder (PTSD). Similarly, among contemporary non-Westernized peoples, a cross-cultural conducted by Ember and Ember (1994) found a relationship between war and various forms of intragroup violence, including domestic violence, assaults, homicides, and violent sports. It is unknown, however, if this positive association between warfare and intragroup violence extends longitudinally for prehistoric populations uninfluenced by modern states.
To test Ember and Ember’s (1994) results in an archaeological culture, this study examines whether or not an association between war and intragroup violence was present during the Mississippian Period (ca. AD 1000-1450) of the Central Illinois Valley (CIV). The Mississippian Period of the CIV represents an ideal context for examining war and violence questions, as considerable evidence of war and violence has been amassed from archaeological and bioarchaeological analyses. High rates of skeletal trauma, fortification construction, and the placement of habitations sites in defendable areas indicate war was of particular concern during this period. Yet, little is known regarding the diachronic and synchronic variation in violence in this region.
In this research, skeletal remains representing 776 individuals from five CIV sites (Dickson Mounds, Larson, Berry, Crable, and Emmons) were analyzed for violence-related skeletal trauma, biodistance, and mortuary data. From the aggregation of these data, two models of intergroup violence and two models of intragroup violence were explored. The intergroup models examined were: 1) warfare victims from the local community and 2) warfare captives. The intragroup models assessed include: 1) domestic violence and 2) male-male fights. Results support the hypothesis that as intergroup violence increased during the Mississippian Period in the CIV, intragroup violence increased concomitantly. While warfare and intragroup violence occurred in low frequencies early in the Mississippian Period, after AD 1200, both intragroup and intergroup violence were likely endemic. / Dissertation/Thesis / Doctoral Dissertation Anthropology 2015

Comparison of Prehistoric and Protohistoric Components at the Lighthouse Bayou Shell Midden, 8Gu114, Northwest FloridaGold, Theodore Gold 04 November 2016 (has links)
The dawn of the eighteenth century in the Apalachicola delta region of the Florida panhandle was a time of major social upheaval that has been underexplored by current research. There are no historic records that describe the events and peoples in the region during establishment of the Spanish missions in the Tallahassee area to the east. Archaeological evidence shows the disappearance of the late prehistoric Mississippian Fort Walton people and the brief emergence of the protohistoric Lamar archaeological culture during the time of the destruction of the Spanish mission system around 1704. The Lighthouse Bayou site, 8Gu114, in Gulf County, has both a Fort Walton and a Lamar component, and therefore offers an opportunity to understand this tumultuous time period better. Comparison of the ceramics shows a transition from incised rectilinear scrolling motifs during Fort Walton to a series of incised and stamped designs, along with the emergence of check-stamping as common surface decorations during Lamar. Temper choices are further indicative: pottery of both components has extensive sand and grit tempering, with only limited shell- or grog-tempered vessels, suggesting that indigenous peoples here did not identify with the missionized Apalachee Indians. The lithic data, while limited, show that both the Fort Walton and Lamar inhabitants were more likely retouching existing tools rather than creating new ones; however, the proportion of flake types suggest that the Lamar inhabitants may have exploited chert to a greater extent than did their Fort Walton counterparts. The faunal data show considerable difference in food source exploitation strategies. The Fort Walton inhabitants used the Lighthouse Bayou site specifically to procure shellfish and fish, while the Lamar inhabitants made use of a wider variety of protein sources throughout the area. These differences suggest a contrast between the two time periods: Fort Walton existed under the relatively stable aegis of the late prehistoric Mississippian era. The Lamar people, while not Apalachee Indians, must have been another group fleeing the conflict amid the destruction of the Spanish missions and the general social collapse in Florida’s early eighteenth century.

Faunal Succession and Depositional Environments within the Lodgepole Limestone (Early Mississippian) of Samaria Mountain, IdahoHines, Gary Keith 01 May 1981 (has links)
Community succession, the orderly changes a community experiences with time, is considered to be the result of either autogenic or allogenic factors working singularly or in combination. It has been further suggested that, as communities undergo succession, certain biological parameters change in a predictable manner. Examination of members 2 through 4 of the Mississippian (KinderhookOsage) Lodgepole Formation of Samaria Mountain, Idaho provides a means to evaluate these concepts.
Within the study section comprised of 125 beds (61.5 m thick), four rock types are recognized. These include: (1) fossiliferous wackestone (78% of beds), which ranges in color from dark-gray (N3) to medium-light gray (N6), is fine to coarse crystalline, has an average insoluble content of 3.1 percent by weight, and an average organic content of 0.25 percent by weight; (2) fossiliferous mudstone (1S% of beds), which ranges in color from dark-gray (N3) to medium-gray (NS), is very fine to fine crystalline, has an average insoluble content of 2.3 percent and an average organic content of 0.30 percent by weight; (3) fossiliferous packstone (6% of beds), which ranges in color from medium-gray (NS) to light-gray (N7), is medium to coarse crystalline, has an average insoluble content of 3.3 percent by weight and an average organic content of O. 17 percent by weight; and (4) crystalline carbonate (1% of beds), which is light-gray (N7) in color, is coarse crystalline, has an insoluble content of 9.3 percent by weight, and an organic content of 0.2 percent by weight. However, at ninety-five percent confidence level, no statistical relationship could be seen between the rock types and either the insoluble contents or the organic content.
Twenty-one taxa, including corals, brachiopods, crinoids, blastoids, gastropods, echinoids, and sharks were recognized, with most taxa ranging throughout the study section. Well-preserved fossils are generally rare. However, this deficiency seems to be due to weathering of the containing strata rather than to currents acting on the skeletons prior to burial. Orientational data support this conclusion. Measurements of the direction (vector) from the apical end to the calical end of the horn coral Zaphrentis show that the orientations of toppled corals is random.
Two biological parameters are calculated for each of the bedding surfaces examined, i.e., diversity and calcified biovolume. Diversity is calculated two ways, i.e., in terms of equitability, and in terms of richness. For richness, values range from 0.0 to 7.41, with a mean of 4.12, and for dominance diversity, values range from 0.0 to 1.95, with a mean value of 0.87. Calcified biovolume, which is used as the basis for inferences involving biomass, ranges from 0 to 30,015 cubic centimeters per bedding surface, with a mean value of 744.1 cubic centimeters per bedding surface.
Three faunal associations, as well as several sub-associations within the three major associations, are indicated by the clustering of indices of affinity. These associations include: (1) Zaphrentis-Crinoid- Syringopora-Echinoid-Cleiothryridina-Unispirifer-Spirifer-Orthotetes- Flexaria-Camarotoechia-Schizophoria-Lithostrotionella; (2) Cruziana-Dwelling tube; (3) Shark-Blastoid-Helminthopsis. Trophic relationships within the three associations suggest that they were the result of two factors: (1) the tendency towards a vertical stratification of the association's members, which resulted in a more efficient use of the water column; (2) direct physical interaction among association members, in the form of predator-prey or symbiotic relationships. The former type of interaction may have been operative between the sharks and blastoids of faunal association 3.
Environmental reconstruction involved the determination of four parameters: (1) paleocurrent direction and intensity; (2) sedimentation rate; (3) bathymetry; and (4) substrate. From the study of both physical and biological evidence, it is concluded that, during the time of Lodgepole deposition a very weak, unidirectional current, or multidirectional currents of similar competency operated over a carbonate-mud substrate. Evidence suggests that the sedimentati on rate was extremely low, and that the Eh= 0 line was just below the sediment-water interface. The water depth at this location was probably below normal effective wave base, but above the zone of oxygen depletion.
Study of fossils on bedding surfaces overlying barren bedding surfaces or surfaces containing fossil hash, suggests that four successional stages can be recognized. Because changes in the faunal composition between the various successional stages appear to take place both with (10 times), and without lithologic changes (16 times), it is concluded that succession may result from either biological modifications of the environment or physical changes. Therefore, succession was both autogenically or allogenically controlled. Additionally, the comnrunities were retrograded to an "earlier" successional stage 24 times within the 125 bed succession.
As succession proceeded through the successional sequence, values for equability-diversity and calcified biovolume generally increase. This trend is in agreement with previously predicted trends. With succession the overall trend observed in the trophic structure appears to be one of an increase in the proportion of filter feeders in the community relative to the proportion of deposit feeders in the community.

Autecology of Selected Genera of Mississippian, Permian and Triassic Ammonoids: Analysis of Coiling GeometriesChatelain, Edward Ellis 01 May 1978 (has links)
Ammonoids were collected from the Chainman Formation (Mississippian) of southeastern Nevada and southwestern Utah, the Phosphoria Formation (Permian) of southeastern Idaho and westernmost Wyoming, and the Thaynes Formation (Triassic) of northeastern Nevada and southeastern Idaho. The collections are interpreted to represent unwinnowed, untransported death assemblages of ammonoids which were subject to chemical conditions of the nekto-benthic environment. Associated lithologies were sampled and geochemically analyzed for content of phosphate and organic matter. Ammonoid fossil collections, combined with ammonoids ilustrated in the literature, were subjected to the graphical W and D analysis of Raup (1967). The basic parameteres involved in the description of shell-coiling geometry are whorl expansion rate, W, and the distance of the generating curve from the axis of coiling of the shell, D. Values of W determined range from 1.32 to 3.96, which correspond to slight and rapid increases in whorl height during coiling. Values of D determined range from 0.02 to 0.55, which correspond to extremes of involute and evolute coiling· geometries, respectively.
Body chamber length corresponds with shell coiling geometry. Values determined in this study range from 10° to 540°. Corresponding W values are 3.96 and 1.50, whereas corresponding D values are 0.02 and 0.40, respectively. Average body chamber length in analyzed ammonoids
is observed to decrease from 297° to 209° from Mississippian to Triassic time. Increase in apertural area accompanied this trend, and a possible consequence was that a greater range of prey sizes was afforded ammonoids with shorter body chambers.
Life-orientation, described as the angle between the apertural plane and the gravitational vector, is calculated entirely on shell form and other geometrical considerations. Recent observations concerning Nautilus, combined with fossil evidence of epizoan encrustation suggest that ammonoids had an ability to control orientation, which is not observed from preservable morphology.
From Mississippian to Triassic time, no trends in reconstructed life-orientation can be substantiated, based solely on Wand D values.
Rotational stability during directed locomotion is important for conservation of the energy budget of this nektonic carnivorous organ ism. This property is calculated by the distance between the center of buoyancy and the center of gravity of the ammonoid. Values deter mined range from .04 (very unstable) to .16 (very stable). Corres ponding W values are 1.50 and 4.00 where corresponding D values are 0.20 and 0.02, respectively. A trend toward increasing average rotational stability (.07 to .10) is noted for amrnonoids from Mississippian to Triassic time.
Efficiency in the utilization of calcium carbonate is the ratio of internal volume of the shell to volume of shell material. Values determined range from 5.80 to 7.25. Corresponding W values are 4.00 and 1.50, corresponding D values are 0.02 and 0.54, respectively. Abundant ammonoids found in black, phosphatic limestones rich in organic matter have an average efficiency value of 6.2. Abundant ammonoids from corresponding light-colored crystalline carbonates have an average efficiency value of 6.02, and indicate no correlation between efficiency and abundance.
Size-frequency distributions are utilized in recognition of opportunistic species of ammonoids. High numerical abundance, high mortality rate of juveniles, small size and conservation of calcium carbonate typifies the paleo-opportunistic species Cravenoceras, Psuedogastrioceras and Ophiceras.
Biovolume-relative abundance distributions are useful in discerning the carrying capacity of the habitat both in number of individuals and species diversity. A large area under the biovolume-relative abundance profile indicates diversification under optimum environmental conditions; a small area under the profile indicates colonization of a stressful habitat. The Chainman, Phosphoria and Thaynes (Columbites Zone) Formations have ammonoid assemblages which show small areas under the biovolume-relative abundance profile, characteristic of anoxic environmental stress. The Permian stratigraphic units correlative with the Phosphoria Formation have ammonoid assemblages which show large areas under the profile and the associated lithologies, i.e., light gray,crystalline carbonates, suggest environments which could support a diversified ammonoid fauna, including large-sized species. Ontogenetic variation produces changes in the body chamber length, life orientation, rotational stability, and utilization of calcium carbonate of the analyzed genera of ammonoids. These ontogenetic variations usually resulted in the development of more involute shell-coiling geometries. Corresponding size-frequency distributions suggest increased mortality rates during ontogeny for some genera (Paracravenoceras, Medlicottia) which show decreasing efficiency in the utilization of calcium carbonate.
