... studied. Results of this work have shown that water production behavior in fractured gas reservoirs is mostly depending on production rate. Also, sensitivity analysis revealed that the sensitivity of coning time to the changes of fracture horizontal permeability is more than changes of matrix horizontal...

... Another approach can be demonatrated to the highly deformable rocks containing relatively incompressible fluids. Pressure drop and effective stress rise result with change in the permeability and well productivity. Depending on the geometry of porous media and boundary conditions variation...

The objectives of the present study are to: 1) Examine the thermal stability of several chelating agents and their salts up to 450°F, and 2) assess the effect of thermal decomposition products on the permeability of carbonate...

... 3 the point of diminishing returns appears to be in the region of 300,000 to 400,000 lb of proppant, a value that varies with formation permeability. With reference to Figure 3 , higher permeability will shift this point to the left (i.e. smaller treatments) whilst lower permeability will shift...
