Modeling Hydraulic Fracture System For Low Recovery Gas Reservoir { Fracture Gas Wells in Low Permeability Layers ( AG Sand Formation) } In Jake South Field

Abstract

In this searching in order to Enhance the productivity of low permeability wells in JF “JAKE FIELD” hydraulic fracture was performed specifically on low permeability layers( AG Formation charactristic with low permeability due the compaction of layers ) in this case permeability less than 0.05 darcay , Hydraulic fracture is performed to well-JS-01 and well –JS-04 In order to increase the well productivity & field recovery factor ,CMG software used with given model (Jake field) and by alternating the fracture parameter and trying different scenario of production, The parameters of fracture to achieve permeability improvement and they are: The fracture width ( 0.3048m )& the fracture half length ( 95.0976m ) The change in oil & gas production and water production was also monitored with the change in the permeability of layers on which the hydraulic fracture was performed , Then it was concluded that the productivity of wells improved after performing hydraulic fracture processon them , and that the process also lead toan improvement the field recovery factor .
