A better understanding of reservoir densification mechanisms is very important for petroleum exploration and controlling the quality distribution in low-permeability reservoirs. Low porosity low permeability, difficult reconstruction, economic infeasibility are factors restricting its efficient production. Systematic analysis was performed to study evolution different microfacies deltaic deposi...

Abstract The mid-Cretaceous thermal maximum (KTM) during Cenomanian to Santonian times from ca. 100 83 Ma is considered among Earth's warmest sustained intervals of the Phanerozoic. time interval also characterized by major paleoceanographic changes in form an oceanic anoxic event and flooding epicontinental seaways, such as Western Interior Seaway North America. We report carbonate clumped iso...

Our objectives are to examine sediment PAH distributions in environments representing contrasting depositional regimes within the York River, VA, a sub-estuary of the Chesapeake Bay. Our study utilizes a suite of geochemical tools to quantify sediment processes influencing the distribution of dissolved and solid-phase PAHs. These tools will enable us to quantify particle residence times in surf...

The carbon-13/carbon-12 ratios of the carbonate and collagen fractions of bone of the sympatric hyrax species Procavia johnstoni and Heterohyrax brucei indicate that the former obtains most of its diet by grazing while the latter is primarily a browser. The carbon-13/carbon-12 ratios of these fractions in fossil bone will record information about diet if they have not been altered during diagen...

Reservoir characteristics and influences by diagenesis sedimentary environment of the Qingshuihe clastic formation Shinan area, Junggar Basin, are studied in this paper SEM, casting thin sections, X-ray diffraction, combining geology logging well data, providing a theoretical guide for further exploration development. The results show that Formation region interest was developed braided river f...

As we move to developing object-oriented programs, the complexity traditionally found in functions and procedures is moving to the connections among components. Different faults occur when components are integrated to form higher level structures that aggregate behavior and state. Consequently, we need to place more effort on testing the connections among components. Although object-oriented te...
