... Abstract Most analytical and numerical flow modelling presuppose isothermal flow behavior in the reservoir. However, for high rates and large consequent drawdown gas reservoirs, the nonisothermal behavior becomes the norm due to the Joule-Thomson (J-T) effect. Other factors, such as a fluid's...

... There are four primary reasons that a depleted gas reservoir be a good candidate for CO 2 storage. First of all, the gas reservoir is a container with a proven integrity. One big concern of CO 2 subsurface storage is that it potentially leaks out to aquifer and surface ( Maldal and Tappel 2004...

... Abstract Shale gas production has gained worldwide attention over the past several years. Production from shale gas reservoirs requires horizontal drilling with multiple hydraulic fracturing to obtain the most economical production. However, there are high cost and uncertainty due to many...

... Abstract Core data from various North American basins with the support of limited amounts of data from other basins around the world have shown in the past that process (or delivery) speed provides a continuum between conventional, tight and shale gas reservoirs ( Aguilera, 2010 ).

... is compensated by larger width. Non-Darcy effects in the fracture are also considered for gas reservoirs. Post-treatment well performance is then estimated, using the optimized well geometry, leading to cumulative production estimates over the well life. Finally, a NPV analysis is employed as the criterion...

... gas reservoir in Haynesville formation. Numerical Modeling of Multi-Fracture Horizontal Shale Gas Wells In conventional reservoir simulation, the size of a simulation grid block is in the order of 10-100 ft. This usually results in simulation models on the order of O(10 5 -10 6 ) grid cells...

... method for production data analysis. To evaluate this model, we selected 50 wells in some gas reservoirs from Xinjiang oilfield, China. The 50 wells have been developed for several years. Therefore, we have enough data on the 50 wells to be applied in this model. It is demonstrated that this model...

... Abstract Crossplots of porosity vs. permeability from various North American basins show that there is a continuum between conventional, tight and shale gas reservoirs. This is significant as some of the key issues, particularly in shale and tight gas reservoirs, are having good estimates...

Abstract This paper presents a simplified, yet rigorous, method of production forecasting for tight/shale gas reservoirs exhibiting extended periods of linear flow, without the use of complex tools. The method is simple as it relies principally on a plot of inverse rate versus square root time...
