5. In Problem 2, the 30 nD shale is fracked, creating a 0.1 mm wide fracture in it all along the 300 ft length. What is the flow rate through the fracture, neglecting the rest of the shale? C. 1 IL 2. A sandstone is 300 ft long, with a cross-sectional area of 20 ft? An oil of viscosity 9 cP is flowing through it. The pressure at one end is 3000 psia, and at the other end it is 200 psia. If the permeability of the sandstone is 30 mD (1 millidarcy = 10-2D), what is the oil flow rate in B/D? Repeat for a permeability of 30hD for a shale (1 nanodarcy=10-9D)
