Experiments in the presence of crude oil were carried out under the same conditions in native cores at a steam residual oil saturation of 7% and 13%. These experiments showed that the optimal steam quality is shifted to approximatively 10 wt...

... Abstract The difficulty of determining effective water saturations in shaly-sand oil reservoirs is an old industry problem. Zones with high water saturation may not be developed even though the resistivity logs show that hydrocarbon exist and production data indicate low water cuts. Reservoirs...

... by the reservoir as the water invades the gas reservoir, the displacement is not 100% efficient ( M.Kelkar, 2008 ). On the other hand it has long been realized that gas recovery from a water-drive gas reservoir may be poor because of high residual saturations under water drive. The Agarwal study (Agarwal, 1965...

... Abstract BP Trinidad and Tobago LLC ("bpTT") operates offshore, along the east coast of Trinidad in predominantly retrograde gas condensate fields, some of which contain reservoirs with thin oil rims. As part of the company's surveillance philosophy, saturation logs have historically proven...

... is inadequate, electric logs are very old or not available. Production from the reservoir has changed the profile of the fluid content over the years and an electric log run in the past does not give a true reflection of the current fluid saturations. This leads to failed NRT’s. Net Oil sand maps in the past...

... oil and gas decreases. It is consistent with the reduction in gas-oil interfacial tension. In addition, the gas phase trapping caused by hysteresis effect is weakened by the confinement effect, resulting in a lower critical gas saturation and a better oil production during CO 2 injection. PVT...

... Abstract Low-salinity waterflooding (LSW) is an enhanced technique that improves oil recovery by lowering and optimizing the salinity of injected water. Previous research demonstrated that the initial water saturation and oil aging during LSW affect oil recovery. This work aims to validate...
