The CH4-hydrate equilibrium curve (dashed) and CO2-hydrate equilibrium curve (solid) on a pressure-temperature plane above 0°C are shown in the figure. The two curves divide the plane in four non-overlapping regions. In which region are CO2-hydrates stable and CH4-hydrates unstable?
Plot of ratio of pressure to gas compressibility factor (P/Z) vs. cumulative gas production (Gp) for a gas reservoir (represented by solid curve in the figure) was shown to a reservoir engineering student.
The student made the following statements:
(I) A water aquifer is attached to this gas reservoir.
(II) P/Z vs. Gp curve must always be a straight line for water encroachment in a gas reservoir.
(III) The ultimate gas recovery is diminished due to water encroachment.

Waste water from oil industry consists of oil in free and emulsified forms. The oil in the free form can be recovered by:
A reservoir model consisting of two porous matrices M and N, separated by a fracture, is shown in the figure. The matrices are strongly water-wet and are saturated with oil of specific gravity 0.8. Water is injected only in the fracture at injection well A. If the Reynolds number for the flow in the fracture conduit is assumed to be less than unity, which one of the following force will dominate oil recovery from the porous matrix M during the water-flood operation?
A fractional flow curve is given for a core for which the irreducible water saturation is 0.2 and the residual oil saturation is 0.3. The initial water saturation in the core is 0.3. If Welge’s method is applied to find the breakthrough saturation and fraction flow of water at breakthrough, which point should be used in the figure to draw a tangent line to the fractional flow curve.
Which one of the following curves represents behavior of oil phase viscosity as a function of pressure in the reservoir (where, Pb is the bubble point pressure of oil)?
Pick out the INCORRECT statement.
