Problem # 4 (not from textbook): As a Summer Intern you are tasked to evaluate 2 completion designs that have the same productivity index and in the same reservoir (i.e., same fluid viscosity, formation volume factor, and In(re/rw)=8). Design 1 has the product of k1* h1 be half of Design 2 ( i.e., k*h = (0.5) k*h ). The skin for Design 2 is 9 (i.e., S = 9). Find the skin for Design 1 (i.e., find s). Which design (Design 1 or Design 2) would you recommend? (hint: check or compare skin pressure drop for both Designs)
