Understanding the rock/fluid interaction is key to the success of any enhanced oil recovery (EOR) method. However, EOR methods are significantly affected when the reservoir …
It is widely accepted that oil recovery during waterflooding can be improved by modifying the composition of the injected brine. A typical approach is diluting the formation water to a …
More than half of the oil and gas resources of the world are hosted in carbonate reservoirs. Also, a total of 60% of their residual oil is left unswept during conventional primary and …
The spontaneous combustion of coal in goaf was effectively prevented by adding nano- aluminum hydroxide (Nano-ATH) into the composite foaming agent solution in the …
In mature reservoirs, over 60% of oil remains trapped after waterflooding and can only be recovered using enhanced oil recovery (EOR) methods, including chemical EOR …
Injection of surfactant and polymer at the same time is one of the challenges that reduce their performance in reservoirs. Using a polymeric surfactant (PS) as a single new material …
Surfactant-polymer (SP) flooding is considered an efficient technique to increase the recovery of oil, especially from carbonates reservoirs, because of their complex nature. The …
Several core-flooding-based experimental studies demonstrated the effect of calcium and magnesium ions and it is found that these hard ions have detrimental effects on oil recovery …
With the ever-growing demand for oil and gas today, and the increasing difficulty of recovering hydrocarbons from carbonate reservoirs, it is vital to apply enhanced oil recovery …
