... than the no-risk-of-leakage bound in any given reservoir. Thus we also examine the form of the gas cap established by the rising CO 2 plume, and we simulate leakage from this gas cap through the top seal. Our leakage scenario is simulated in different cases with homogeneous and heterogeneous capillary...

... bubble point pressure is 1950 psia; the reservoir was undersaturated and no gas cap present at initial conditions. Two core samples were taken. The primary drive mechanism is solution gas expansion aided by gravity segregation. Over two thousand acres were studied with well spacing between eighty and 160...

To exploit this oil column, we can enact a few options, such as Placement of horizontal wells in a thin-oil column (< 40 ft) is a challenge and depends on relative drive indices of the gas cap and the aquifer. Typically, the gas-cap expands easily as depletion occurs in the system...

Abstract This study of Friendswood Field reviews a 60-year history of reservoir management that includes an efficient depletion of the oil column and a successful high-rate blowdown of the gas cap.

... Abstract The Panna field is a heterogeneous limestone reservoir consisting of a thin oil column overlain by a gas cap and underlain by a water column. The reservoir is coning dominated and the wells show a marked increase in Gas Oil Ratio (GOR) and water cut very early in the production history...

.... Conventional methods generally fail to produce robust results because of the variations in the Archie exponents m , and n , both in space and time. The saturation variations originate from the double displacement processes employed for improved recovery, which have generated a sizable gas cap and a moving...

... with significant permeability, that have low porosity (5-6 PU). The challenge was to monitor gas cap expansion, fluid movement due to re-injection, and voidage. At the same time the objective was to identify low GOR intervals behind pipe for possible recompletion. A number of different examples are shown...
