Farnsworth Field Unit (FWU), a mature oilfield currently undergoing CO2-enhanced oil recovery (EOR) in the northeastern Texas panhandle, is study area for an extensive project undertaken by Southwest Regional Partnership on Carbon Sequestration (SWP). SWP characterizing field and monitoring modeling injection fluid flow processes with intent of verifying storage CO2 timeframe 100–1000 years. Co...

Reef and temperate carbonate units alternate in the upper Miocene^Pliocene stratigraphic record of Betic basins palaeogeographically connected to the Mediterranean. Shallow-water coralline algal assemblages in temperate units differ in taxonomic composition from those in reef carbonate units. The difference attains the subfamily level since the temperate lithofacies are characterised by assembl...

Shale oil has become a global hotspot of unconventional exploration and development. In this study, the latest drill core experiment analyses Qingshankou Formation in northern Songliao Basin were used to evaluate its lithofacies classification, sedimentary environment, pore types, pore-throat structure characterization, shale potential. Lithofacies classification was determined according total ...

The Tirgan Formation (Barremian – Aptian) is exposed in the Kopet Dagh in northeast Iran. One stratigraphic section in Zavin was measured with a thickness of 110 meters. This Formation in section consists of three parts (including lower carbonate, limy shale – marl and upper carbonate rocks). Based on the study of 94 thin sections, 10 carbonate and 2 siliciclastic lithofacies have been identifi...

The lattice of the set partitions of [n] ordered by refinement is studied. Suppose r partitions p1, . . . , pr are chosen independently and uniformly at random. The probability that the coarsest refinement of all pi ’s is the finest partition {1}, . . . , {n} is shown to approach 0 for r = 2, and 1 for r ≥ 3. The probability that the finest coarsening of all pi ’s is the one-block partition is ...

the kashkan formation (paleocene to middle eocene), consists of conglomerate, sandstone, and siltstone in the zagros folded zone, southwest iran. type of the sedimentary facies, architectural elements and trace fossils show that kashkan deposits were formed in a low sinuosity braided stream system, with north to south flow direction. the formation displays coarsening-upward succession reflects ...

Internal wave packets propagating vertically in the oceanic thermocline are investigated with numerical simulations. For a typical set of environmental and packet parameters, it is shown that linear dispersion will have a significant effect on the spreading and decay in amplitude of these packets. Sufficiently strong packets are shown to generate turbulence that forms a continuous ‘scar’ of sma...

The investigation of a two-phase flow in porous media has significant implications for wide range applications. Previous research focused on exploring the variations and phase fields using experimental numerical methods. However, complex structure introduces many uncertainties that can impact outcomes. In recent years, some scholars have tried to study dynamic mechanics through typical structur...

Lithofacies are the fundamental geological units for shale oil and gas exploration development, soluble organic matter (SOM) is most similar to crude in composition. Both aspects attract our attention interpretation of SOM different lithofacies, which can provide direct evidence predict “sweet spots”. Here, twenty-five samples were collected from Eocene Shahejie Formation Dongying Sag subjected...

The current study depends on lithofacies analysis of Kolosh Formation at Tigran region in north-eastern Iraq. Depending the physical criteria as grain size, color, texture, and etc., formation is divided to five lithofacies: pebbly sandstone, coarse graded mudstone shale lithofacies. Several sedimentary cycles depositional regimes were fixed studied section represent by high energy regime sands...
