Natural gas production from marine hydrate reservoirs has become attractive to the oil and industry in recent years. It is still a great challenge recover natural efficiently mainly due sand wellbore collapse problems associated with scheme of depressurization. The thermal recovery method not been proven economical high cost energy consumption. This study focuses on using geothermal assist depr...

When drilling or exploiting fractured formations, gas fluid displacement and invasion often occur, is very subtle difficult to find. The in the fracture enters wellbore arrives near wellhead with fluid. Improper treatment may lead serious accidents such as lost circulation blowout. In this study, using computational dynamics (CFD) simulation software for modeling grid generation, based on volum...

Background Considerable effort has been devoted to the development of reservoir simulation tools for the oil industry, and there are high-quality simulators available that handle effectively many of the flow problems appropriate to oil and gas reservoirs. One area where simulator development is continuing, however, is in the simulation of processes in which multiple components transfer between ...

Weiyuan gas field, located in the Sichuan basin of south China, is a large marine gas field with the oldest reservoir (the Sinian sequences) in south China. The hydrocarbon origin of the gas field has long been debated by petroleum geologists. Recently, it was recognized that a paleo-oil pool maybe the significant contributor to the gas field. Consequently, when the paleo-oil pool had been crac...

Oil-reservoir management using measurements and control techniques have been in use by oil and gas industries to improve the production and maintenance of the existing oil reservoirs. In the course of this project the applications of UWB radar systems and techniques to acquire near real-time information about the oil reservoir conditions are studied. Various oil reservoir structures such as oil...

RESULTS Drilled four wells based on the model, successfully predicting the type and thickness of reservoir facies, enabling the operator to pursue optimal field development strategies with higher confidence in the distribution and connectivity of critical flow units. Modeling reservoir architecture with limited data After successfully developing Cretaceous reservoirs in several northern Kuwait ...

Tight gas reservoirs are characterized by single-phase (gas) or two-phase (gas and liquid) flow in extremely low-permeability, highly heterogeneous porous/fractured, and stress-sensitive rock. Gas flow in such tight formations is further complicated by other co-existing processes, such as Klinkenberg effect, non-Newtonian or non-Darcy flow behavior, due to strong interaction between fluid molec...
