Successful exploitation of tight sandstone gas is one the important means to ensure “increasing reserves and production” oil initiative also ways national energy security. To further improve accuracy historical matching field data such as production bottom-hole pressure during process this type reservoir, in study, a new expression wellbore for uniform flow vertical fractured wells Laplace spac...

A lot of oil and gas reservoirs have been or will be abandoned in petroleum industry. In this study, we pointed out that these oil and gas reservoirs might be transferred into exceptional enhanced geothermal reservoirs with very high temperatures by oxidizing the residual oil with injected air. A concept to generate power from these exceptional enhanced geothermal reservoirs by using geothermal...

The physical properties of tight gas reservoirs are poor. During the stable production period wells, most recoverable reserves produced in declining stage. It is great significance to accurately study law gas. However, declines rapidly early stage and slower middle late stages, single model fitting prediction results have large errors. In view above problems, according change characteristics de...

Although gas desorption is a known phenomenon, modeling fluid flow in tight reservoirs often ignores the governing effect, assuming that viscous transport predominant controller, resulting an erroneous prediction of mass and calculations. Thus, developing new model accommodating all major contributing forces such medium essential. This work introduces comprehensive suitable for unconventional r...

Low to ultralow permeability formations require "special" treatments/stimulation to make them produce economical quantities of hydrocarbon and at the moment, multi-stage hydraulic fracturing (MSHF or MHF) is the most commonly used stimulation method for enhancing the exploitation of these reservoirs. Recently, the slot-drill (SD) completion technique was proposed as an alternative treatment met...
