Facies modeling is an essential part of reservoir characterization. The connectivity of facies model is very critical for the dynamic modeling of reservoirs. Carbonate reservoirs are so heterogeneous that variogram-based methods like sequential indicator simulation are not very useful for facies modeling. In this paper, multiple point geostatistics (MPS) is used for facies modeling in one of th...

The Permian Council Grove Group in the Panoma Field of southwest Kansas has yielded 80 x 10 meter of gas from approximately 2600 wells from a 60-meter interval at depths of 800-1,000 meters since its discovery in the 1960’s. Initial gas saturation, production rates and cumulative production in the Panoma Field are controlled by the distribution of porosity and permeability in the field, which a...

The Trout Valley Formation of Emsian–Eifelian age in Baxter State Park, Maine, consists of fl uvial and coastal deposits that preserve early land plants (embryophytes). Seven facies are recognized and represent deposits of main river channels (Facies 1, 2), fl ood basin (Facies 4), storm-infl uenced nearshore shelf bars (Facies 3), a paleosol (Facies 5), and tidal fl ats and channels (Facies 6,...

[1] Clay-rich mass transport deposits (MTDs) in the Ursa Basin, Gulf of Mexico, record failures that mobilized along extensional failure planes and transformed into long runout flows. Failure proceeded retrogressively: scarp formation unloaded adjacent sediment causing extensional failure that drove successive scarp formation updip. This model is developed from three-dimensional seismic reflect...

The western Tianshan high-pressure/low-temperature orogenic belt in NW China contains eclogite-facies metavolcanic rocks and omphacite-bearing blueschists. Previous Sm-Nd (omphacite, garnet, glaucophane, whole rock) and Ar/Ar (crossite) dating of eclogite-facies rocks has suggested an age of ca. 345 Ma as the best approximation for the timing of peak metamorphic conditions. The samples describe...

Integration of ichnologic, sedimentologic, and stratigraphic studies of cores from Lower Pennsylva-nian oil and gas reservoirs (lower Morrow Sandstone, southwest Kansas) allows researchers to distinguish between estuarine-and open-marine deposits. This study represents one of the first published ichnologic analyses of a Paleozoic reservoir and, therefore, provides a unique opportunity to test t...

Palimpsests are large, circular, low-relief impact scars on Ganymede and Callisto. These structures were poorly understood based on Voyager-era analysis, but high-resolution Galileo images allow more detailed inspection. We analyze images of four Ganymedean palimpsests targeted by Galileo: Memphis and Buto Faculae, Epigeus, and Zakar. Ganymedean craters and Europan ring structures are used as t...

The aim of this research was to accurately measure the surface of the semi lunar articular surface of the pelvis (facies lunata acetabuli) and the variability of the acetabular geometry, as well as to determine the correlation between measured parameters. 30 macerated anatomical specimens of pelvic bones were measured. The radius and depth were measured in the classical way, while cartilaginous...

The occurrence of power law relationships in the spatial distribution of sedimentary lithotopes has been identified in both modern and ancient carbonate depositional bodies. In this study, facies patterns and their spatial relationships are investigated quantitatively in an Arabian Gulf shallow subtidal carbonate ramp setting, using a synergy of IKONOS satellite imagery and vessel-based acousti...

6 [1] Clay-rich mass transport deposits (MTDs) in the Ursa Basin, Gulf of Mexico, record 7 failures that mobilized along extensional failure planes and transformed into long runout 8 flows. Failure proceeded retrogressively: scarp formation unloaded adjacent sediment 9 causing extensional failure that drove successive scarp formation updip.
