Paper presented at the Annual Technical Meeting, June 7–9, 1998
Paper Number: PETSOC-98-25
... Abstract Experiments performed on immiscible displacement of heptanes and mineral oil by water in capillary tubing showed that capillary pressure during drainage and imbibitions were constant over a range of velocity from 10 −4 to 10 −2 m /s. The results obtained were quite different from...

... In a previous study, we have simulated gas-oil gravity drainage in fracturedporous media. Numerical simulation results showed that fracture capillarypressure is an important two-phase flow parameter in a matrix/fracturesystem. The main focus of this paper is to analyze experiments on viscousdisplacement...

... phase system flowcannot be described as simply "drainage" or "imbibition ". Rather, flow must bedescribed as "drainage / drainage ". "drainage / imbibition" or "imbibition /imbibition " to account for the change in saturation of all three phases. Thispaper elaborates on the issues governing three phase...

... Abstract We propose a simple approach to simulate gas-oil gravity drainage process in fractured porous media by using an appropriate fracture capillary pressure curve and an expression for effective fracture liquid permeability. The effective fracture liquid permeability is approximated...

... Abstract Accurate drainage and imbibition relative permeability data are essential for the accurate prediction of the performance of heavy oil reservoirs undergoing cyclic steam stimulation or steam drives. There is very little published data regarding steady state relative permeability...

... producers. However, even with these frac- turing techniques, much of the reservoir may be left unrecovered because of the unique drlinage pattern in low permeability reservoirs. Smith1 (1979) has dem- onstrated chat the drainage around a fracture-stimu- lated well is elliptical rather than radial...

... derived from observations that counter-current imbibition and gravity drainage are time-dependent recovery mechanisms and can more effectively contribute to ultimate recovery at lower reservoir withdrawal rates. This paper describes results of a study to determine the effects on oil recovery of production...
