Unformatted text preview: simply remembering that the flow is always from point 1 to point 2, or in this case from the well bore (point 1) to the reservoir boundary (point 2). For example, the radial flow equation for fluid injection has fluid entering the reservoir at the well and flowing towards the boundary, rather than the other way around for production. 141.2 ln e w e w kh q r r Φ - Φ = - where the flow rate now is an injection rate into the reservoir. Using this equation please compute the injection pressure at the well bore for the following conditions. 30 md 25' =1 cp 3,000 psi 1 bbl/min = +20 deg 745' 0.2' e e w k h p q r r μ θ = = = = = = Note that the angle of the formation now indicates the well is the lowest part and injection must flow up hill....
