Production of gases from gas-condensate reservoirs are known to bear certain challenges largely due to the formation of retrograde condensates that hinder gas flow. The drop out of this liquid creates flow regions that are characterized by the liquid saturation as it affects the mobility of the two phase flow, thereby preventing the effective modeling of well productivity. In this study, a pred...

Carbon Dioxide Storage in Natural Gas Reservoir — The general idea of CO2 disposal in gas reservoirs is that the underground volume of the ultimately recoverable hydrocarbons (gas and condensate) is replaced by CO2. This paper investigates the feasibility of carbon dioxide disposal in depleted gas reservoirs. Gas reservoirs are a practical storage site for the carbon dioxide, because the presen...

The fluid mobility characteristics in the pores with various apertures for tight-sandstone would finally determine and production of tight oil gas reservoirs. In this study, core samples collected from Middle Jurassic Xishanyao Formation Santanghu Basin were launched measurements under centrifugal speeds. With NMR fractal theory pore classification method, types classified, different also inves...

In addition, one of the following statements should be included. Abstract The Piceance Basin, CO is a type locale for unconventional tight-gas sandstone in the Rocky Mountains (Law, 2002). Productive Williams Fork sandstones are extremely heterogeneous fluvial to marginal marine reservoirs that have very low permeability (<0.1 md) that typically require expensive hydraulic fracturing with 10-20...

nowadays one of the most important energy sources is natural gas. by depletion of oil reservoirs in the world, natural gasâ will emerge as the future energy source for human life. one of the major concerns of gas suppliers is being able to supply this source of energy the entire year. this concern intensifies during more consuming seasons of the year when the demand for natural gas increases, r...
