Pressure Derivative Studies of a Laterally Infinite Reservoir with a Horizontal Well
Dimensionless pressure derivatives of a laterally infinite reservoir drained with a horizontal well are studied. The effect of anisotropy on the derivative response is also studied. It is revealed that anisotropy mainly affects the start of the late radial flow regime, and for cases where LD is small (<0.5), affects the end of the first radial flow regime. Time criteria equations were also developed to delineate flow periods and have been shown to give good results for the range 0.00005 ≤ rwD ≤ 0.01 and 0.1 ≤ LD ≤ 100.
