Question: (20 points) A 100 ft thick, 10 md sandstone pay zone at a depth of 10000 ft is to be acidized with an acid solution

  1. (20 points) A 100 ft thick, 10 md sandstone pay zone at a depth of 10000 ft is to be acidized with an acid solution having a specific gravity of 1.07 and a viscosity of 2 cp down a 2-in.-ID coiled tubing. The formation fracture gradient is 1.0 psi/ft. The wellbore radius is 0.328 ft. Assuming a reservoir pressure of 5,000 psia, drainage area radius of 1,000 ft and skin factor of 15, calculate
