The oil production after fracturing is mainly affected by the net pressure, oil saturation, pumping scale, plugging distance and formation pressure. With the increase of pumping scale, the horizontal fracture...

Abstract Field A is located offshore Malaysia, identified as the candidate for a pilot project to evaluate the effectiveness of alkali-surfactant (AS) slug to improve recovery factor through the reduction of residual oil saturation. The pilot project utilized single well chemical tracer test...

... permeability curves, particularly including a reduction of the residual oil saturation. Cores that originally display oil-wetness may retain much oil at the outlet of the flooded core due to capillary pressure being zero at a high oil saturation. This end effect is difficult to overcome in high permeable cores...

It provides high-resolution spectroscopy with a much-improved accuracy and precision of all elements measured, including the key element for oil saturation, carbon. The carbon measurement is used conventionally for C/O, and it is used directly to derive total...

... model that was previously carried out suggests that water flood will ultimately achieve high volumetric sweep in the UZSD and MZSD but will also leave remaining oil saturation (ROS) of the order of 30% ( Haliburton Phase 2 Report, 2012 ). This combination of high water flood volumetric sweep and ~30...
