In a faulted reservoir the principle of superposition for the pressure drop using diffusivity equation is applicable

Q. In a faulted reservoir, the principle of superposition for the pressure drop using diffusivity equation is applicable. This is due to

(A) high Reynolds number flow in the well.

(B) constant permeability.

(C) pressure dependent viscosity.

(D) linearity of the diffusivity equation.

Ans: linearity of the diffusivity equation.
