2INTRODUCTION TO MASTER THESISFirst Part IntroductionProduction of oil is divided into three phases such as primary, secondary and tertiary.Enhanced oil recovery refers to symbolize oil recovery beyond primary and secondary oilproduction. Primary oil recovery is restricted to hydrocarbons, which naturally gets up to thesurface, or those that exercise artificial lift devices such as pump jacks. Secondary recovery alsoproduces oil through water flooding. This method employs water and gas injection, which let theoil to be displaced and risen to the surface. US Department of Energy found that these twomethods are only capable to remove 25% oil from the oil (Lake et al., 2014). It is only tertiaryrecovery method which remove 75% oil from the well. Enhanced oil recovery is an initiation,which targets to improve oil production up to 75% from the well. Oil recovery problems nowadaysThe energy of the oil reservoir required to produce oil is not enough because of thedistribution of permeability in the reservoir that has been uncertain at certain stages. Thestatistical approaches are based on limited numbers of assumptions related to the heterogeneityof the reservoir. The recovery of oil from the gas drive reservoirs is quite low that ranges inbetween 5 to 30 percent. The oil reservoir is not much effective to produce oil because thepressure has dropped significantly. Due to this, the expansion of gases that are dissolved in thewater and oil has taken up most of the drive energy present in the reservoir. The demands haveincreased though the supply is not sufficient to cater the needs and requirements of people(Yousef, Al-Saleh & Al-Jawfi, 2012).
