Abstract Oil rim reservoirs are characterised with a small thickness relative to their overlying gas caps and underlying aquifers the development these planned very carefully in order avoid water coning maximise oil production. Studies have shown low recoveries from injection, while foam alternating injections resulted positive recoveries, it is viewed that an option of application chemical enh...

Oily sludge is one of the most significant solid wastes generated in the petroleum industry. It is a complex emulsion of various petroleum hydrocarbons (PHCs), water, heavy metals, and solid particles. Due to its hazardous nature and increased generation quantities around the world, the effective treatment of oily sludge has attracted widespread attention. In this review, the origin, characteri...

In recent years, many core displacement experiments of oil by seawater performed on chalk rock samples have reported SO4 2−, Ca, and Mg as potential determining ions for improving oil recovery. Most of these studies were carried out with outcrop chalk core plugs. The objective of this study is to investigate the potential of the advanced waterflooding process by carrying out experiments with re...

Steam-Assistant-Gravity-Drainage (SAGD) has become one of the most commonly used thermal recovery processes to extract heavy oil from oil sand reservoirs, especially in Northern Alberta, Canada. However, due to geological history, interbedded shales (IBS) in the reservoir act as barriers due to their low permeability and as such hinder the progression of the steam chamber. Cap-rock integrity al...
