GEOCHEMICAL CHARACTERIZATION OF THE BONE SPRING FORMATION, DELAWARE BASIN, USING CHEMOSTRATIGRAPHY AND INTEGRATED PETROPHYSICS
… Previous investigations have utilized cores and wireline logs to provide high-resolution chemo-facies segregation, which can be correlated with reservoir and rock properties; however,core and wireline logs are sporadically collected, whereas drill cuttings are available from most wells. For this …

Stratigraphic Analysis and Reservoir Characterization of the Late Oligocene-Early Miocene, Upper Yenimuhacir Group, Thrace Basin, Turkey
… of the target formations were determined using wireline logs from three wells. A right-lateral strike slip or reverse fault system and associated NW-SE trending asymmetric fold extend across the study area. Both the fault system and the fold are truncated beneath the Miocene unconformity and are …

State-Wide Sequence Framework of Mixed Carbonate-Siliciclastic Ramp Reservoirs: Mississippian Big Lime, West Virginia, USA
Well-cuttings data and wireline logs in conjunction with limited core and outcrop data are used to generate a regional, three dimensional high resolution sequence framework for Upper Mississippian (Chesterian), Big Lime carbonates, West Virginia, U.S.A.. The analysis was done using the washed …

Prediction and measurement of special core analysis petrophysical parameters in the Nubian sandstone of the North Africa
… parameters from minimal core training data and wireline logs. The SCAL data was obtained from measurements on core plugs undertaken at the Libyan Petroleum Institute (L.P.I). Previous neural network studies have attempted to predict routine core analysis parameters, such as permeability, but not …

Depositional Facies and Petrophysical Characterization of the Leonardian Carbonate (Lower Clear Fork), Tex-Mex, S.E. Field, Central Basin Platform, West Texas
… of Lower Clear Fork cored sample, core data, and wireline data from a key well. Key data utilized included core descriptions, wireline logs, routine core analysis data, petrographic thin sections, and whole rock mineralogical data from X-ray Diffraction. These data helped to (1) determine the …

Early and Middle Atokan Lithostratigraphy and Reservoir Development, Northern Arkoma Basin, Northwestern Arkansas
… record across the basin.</p> <p>Using PETRA, wireline logs were used to construct two sets of stratigraphic cross-sections that document the depositional changes that occurred during Arkoma Basin subsidence and associated structural events in northwestern Arkansas. Both sets of cross-sections …

Integrated approach to solving reservoir problems and evaluations using Sequence Stratigraphy, Geological Structures and Diagenesis in Orange Basin, South Africa"
… across the 5 blocks of the basin, digital wireline logs (gamma ray, resistivity, density and neutron), core (sidewall and core) and ditch cutting samples from 10 wells of interest. The digital seismic section and wireline logs were subjected to manual and computer interpretation using …

Deposition and diagenesis of a portion of the Frobisher-Alida Interval (Mississippian Madison Group), Wiley Field, North Dakota
… or the Mississippian Mission canyon Formation. Wireline logs and cores from closely spaced wells in, and adjacent to, the Wiley Field, Williston Basin, North Dakota were examined. Information derived from the wireline logs was used to construct several maps which show that there was little or no …

Stratigraphy and Depositional Environment of the Middle Atoka Formation, Central Arkoma Basin, Western Arkansas
<p>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.</p> <p>The middle Atoka formation …

Fluctuations in resistivity in the Tuscaloosa Marine Shale, southwest Mississippi and southeast Louisiana
… calibrated with the resistivity readings from wireline logs give evidence that the increase in resistivity is not due entirely to the generation of oil, but instead caused by the relationship of pore fluids, porosity, and mineralogy. The strongest influence is the amount of carbonate content …

Submarine channelforms and fans in the Miocene Moki and Mount Messenger formations, Taranaki Basin, New Zealand
… geomorphology, integrated with analysis of wireline logs, core, and outcrops, to better understand the occurrence of sediment conduits and fans within the Moki and Mount Messenger formations. Results show that in southern Taranaki Basin, increased sediment influx resulted in steepening of …

Tectonic history of Billings and southern McKenzie Counties, southwestern North Dakota
… </p><p> Data were collected from the wireline logs of 931 oil wells within the study area. From these, a total of 45 log markers were picked from the Precambrian basement and the Pierre Formation (Cretaceous). Structural maps were used in conjunction with trend surface residuals to …

Reservoir characterization using seismic inversion data
<p>Reservoir architecture may be inferred from analogs and geologic concepts, seismic surveys, and well data. Stochastically inverted seismic data are uninformative about meter-scale features, but aid downscaling by constraining coarse-scale interval properties such as total thickness and average …

Mesozoic geology of the Agulhas Bank, South Africa
… cores and sidewall cores and a variety of wireline logs. The existing Mesozoic litho-stratrigraphic framework was supplemented by defining reference stratotypes for the Swart¬kops end Sundays River formations. Subsurface stratotypes are defined for two new units; they are termed the Infanta …

The sedimentology and stratigraphy of Salt Creek Field, Kent County, Texas
… with 3D seismic data, and more than 250 wireline logs allowed the construction of the stratigraphic model. The reservoir is mid-late Pennsylvanian units composed of four composite sequences (Canyon-Cisco) in age, three of which are Canyon composite sequences and one Cisco composite …

OVERPRESSURE AND COMPACTION IN THE LOWER KUTAI BASIN, INDONESIA
… lateral reservoir drainage. The pressure data, wireline logs and other data such as temperature and vitrinite reflectance data have been re-examined to analyse the overpressuring in this area. Unloading mechanisms have been considered as alternatives to disequilibrium compaction. The reasons for …

A detailed gravity study over a known Devonian carbonate buildup: the Shell Golden Reef, northwestern North Dakota
… 2400 meters. Based only on information from wireline logs and core from two boreholes, the Shell Golden well #34X-34 has been previously interpreted as a pinnacle reef with 70 meters of relief and undetermined diameter. The basin regime of the Elk Point shelf created an environment that …
