Pressure transient analysis for naturally fractured gas reservoirs: field cases
This paper presents the analysis of three field tests carried out in two particular naturally fractured gas reservoirs, whose interpretation could properly be accomplished by using a single infinite conductivity vertical fracture model. The model considers the intersection of the well by a planar fracture and that the matrix is homogeneous and isotropic. Conditions of the tests include approximately constant flow rate before shut-in in the first case and variable flow rate before shut-in in the second case. A square root group is discussed for test analysis where final flowing conditions were of linear flow. A new type curve corresponding to linear flow conditions under the effect of wellbore storage is presented.
