physical and chemical properties of  crude oil, including viscosity and api gravity, are commonly inherited  from the  early organic matter, environmental conditions in which they were deposited and depth of burial of the source beds. api gravity increases in deeper burial due to higher thermal maturation of organic matter in the source rocks and consequently, generation of lighter saturated hy...

The work flow of migration velocity analysis (MVA) is widely used in seismic exploration of hydrocarbon reservoirs to refine velocity models and obtain precise information about subsurface structures. Therefore the velocity uncertainty introduced in the MVA process directly affects assessments of structural uncertainty and reservoir volumes. In order to quantify the velocity uncertainty in MVA ...

Numerical simulation of uid ow in a hydrocarbon reservoir has to ac count for the presence of wells The pressure of a grid cell containing a well is di erent from the average pressure in that cell and di erent from the bottomhole pressure for the well Peaceman This paper presents a study of grid pressures obtained from the simulation of single phase ow through an isotropic porous medium using d...

The Upper Cambrian Xixiangchi Formation in the Southern Sichuan Basin, China, has favorable hydrocarbon accumulation conditions. factors and enrichment conditions of this formation were key considerations study. By analyzing core, thin section, seismic, geochemical data, research shows that there are many sets granular crystalline dolomite reservoirs vertically, with thickness single-reservoir....

The wetting of the liquid fluorocarbon (perfluoromethylcyclohexane) on the liquid hydrocarbon (eicosane) surface was studied just above the eicosane melting point, where the eicosane exhibits surface freezing (SF) behavior. The thickness of the wetting layer was controlled by changing the fluorocarbon chemical potential relative to the reservoir through temperature differences T. The evolution ...
