Water Influx Models Ppt. K < 1 md results in neglible water influx, independent of aquifer size. Is the cumulative water effiux from the aquifer or influx into a reservoir. Where t = time, days k = permeability of the aquifer, md φ = porosity of the aquifer μw = viscosity of water in the aquifer, cp ra = radius of the aquifer, ft re = radius of the reservoir, ft cw = compressibility of the water, psi−1 cf. For an active aquifer as pressure drop due to expansion moves out the expanding water has to move a greater distance to the oil or gas zone.
Aquifer sizes often range from 1 to 10 times the hcpv, and may sometimes be 100s of times the hcpv. When influx is small schilthuis steady sate can usually be used. For an active aquifer as pressure drop due to expansion moves out the expanding water has to move a greater distance to the oil or gas zone. The separation of the water influx problem into a rate equation and a material balance equation, not requiring superposition, makes the concepts and calculations quite simple and easy to apply. Is the initial encroachable water in place at initial pressure p;, and w.

Is the initial encroachable water in place at initial pressure p;, and w. Is the cumulative water effiux from the aquifer or influx into a reservoir. K < 1 md results in neglible water influx, independent of aquifer size. When influx is small schilthuis steady sate can usually be used. 1 and 2 (see appendices a and b for complete derivation), we can obtain the equation expressing the instantaneous rate of. Water Influx Models Ppt.
Tank model indicates that unsteady state model is the exact solution. The separation of the water influx problem into a rate equation and a material balance equation, not requiring superposition, makes the concepts and calculations quite simple and easy to apply. The mathematical water influx models that are commonly used in the petroleum industry include: When influx is small schilthuis steady sate can usually be used. 1 and 2 (see appendices a and b for complete derivation), we can obtain the equation expressing the instantaneous rate of. K < 1 md results in neglible water influx, independent of aquifer size.
