Question:

Consider a geothermal reservoir (see Figure 32.17)

-wellhead caprock wellbore radial flow reservoir Pw Pr т.


At a depth of 1.5 km, modeled as a cylindrical volume of radius r = 5 km and height h = 500m, with pressure at the periphery of pr ≅ 15 MPa, pressure at the bottom of the well of pw ≅ 12 MPa, and permeability of K ≅ 50 mD. Use the answer to Problem 32.6 to estimate the mass flow rate through a well bore of radius rw ≅ 0.125 m. Assume that the fluid is water at roughly 180 C, where the viscosity is η ≅ 0.15 cP.
