For a reservoir with the following data: → pore-volume compressibility is 17x10-6 psi-1 overburden pressure gradient...
3. For a reservoir whose pore-wolume compressibiliy is 1Tx10 psi, and where overburden pressure and pore pressure increase by 1 psi and 0.5 psi, respectively, per foot of depth, show that the porosity decreases by 1%(00,-0.99) for every 1000 feet increase in depth.
16. (6 pts) Porosity = pore volume/total volume of hydrated cement specimen. The capillary pore volume can be estimated based on the following equation: Ve=w/e-0.360 cm /g of original cement powder where Ve= capillary pore volume; and a = degree of hydration. The specific gravity of cement is 3.15. For a cement paste with w/c=0.5, a =0.75, and assuming the total (external) volume of cement paste does not change after mixing, calculate the following: 1) (3 pts) The capillary porosity...
1. Consider the following 2D reservoir (different pressure boundaries), where unsteady-state single-phase oil flow is taking place. Use a time step of 10 days and generate the system of equations (implicit, backward-difference scheme), but DO NOT attempt to solve the equations.

Problem 3 A pipeline delivers water from Reservoir 1 to Reservoir 2 as shown in the following figure. The water levels at Reservoirs 1 and 2 are 50 ft and 20 ft, respectively. A globe valve is installed in the pipeline with a minor head loss coefficient k 10. The pipe from Reservoir 1 to the globe valve is 1000 ft long and 6 inches in diameter. The pipe from the globe valve to Reservoir 2 is also 1000 ft...
C). The following data are available for a newly discovered gas reservoir: GWC = 9700 ft, Centroid depth = 9537 ft, Net bulk volume (V) = 1.776 × 1010 ft3, ∅ = 0.19 Swc = 0.20, γg = 0.85 Although a gas sample was collected during a brief production test, the reservoir pressure was not recorded because of tool failure. It is known, however, that the water pressure regime in the locality is Pw = 0.441D + 31 psia and...
