Question

PROBLEM No. 4: A 2-mile wide reservoir consists of several layers as shown below. An incompressible liquid with 1.5 cp viscosity flows through the reservoir at steady-state. Compute the flowrate (bbl/day) of the liquid through the layers P- 750 psia h- 50 ft h-30 f k-120 md P-2300 psia 140 md 200 md k-70 md h- 10 ft L-2.4 miles L-3.6 miles PROBLEM No. 5: A 3000-ft diameter unit in a reservoir has a permeability of 320 md, and is produced by a 9" well While drilling the well, the reservoir permeability is damaged down to 130 md in a zone 5 feet in diameter around the well. Acid stimulation of the well elevated the damage zone permeability up to 560 md. Compute the unit's average permeability before and after stimulation and write your conclusion.
