Your given the following well configuration in a reservoir (Borrowed from Craft and Hawkins). Two wells are located 2850 ft apart. The static well pressure at the top of perforations 9315 ft subsea) in well 2 is 4370 psia and at the top of perforations (9610 ft subsea) in well 1 is 4365 psia. The reservoir fluid gradient (i.e. (static) hydraulic pressure gradient) is 0.30 psi/ft, reservoir permeability is 55md, and reservoir fluid viscosity is 0.84 cp. Assume area open to flow is constant everywhere between the wells. Well #1 Top Perf. 9610 ft 3880 psia 20 ft 2850 ft sin(0)=0.1035 Cross section between two wells. Scales are exegarated! Well #2 As == Datum_2 9100 ft Top Perf. 9315 ft 3850 = 1. Asuming steady state flow calculate the Darcy velocity (i.e. v q/A) in this reservoir between these two wells? Is the flow from well 1 to well 2 or vice versa? 2. If the reservoir consists of two layers, the lower layer is 15 ft thick and its permeability is 55 md and the upper layer is 5 ft thick and its permeability is 100 md. Calculate the average permeability of this layered system. k μ.
