Factors that affect pressure distribution of horizontal wells in a layered reservoir with simultaneous gas cap and bottom water drive

Understanding the behaviour of pressure distribution completed in two layered reservoir subject to both active gas cap and bottom water drive mechanisms is very important in reservoir management. To determine the factors that affect pressure distribution of horizontal wells in a layered reservoir subjected simultaneously with a gas-cap at the top and bottom water drives, well completion was carried out in a particular...

Sensitivity study of low salinity water injection in Zichebashskoe Oilfield

Presently, low salinity waterflooding is considered one of the most promising and cost-effective EOR methods. Although the recovery mechanisms are still uncertain, decrease of residual oil saturation and alternation of rock wettability are considered to be main mechanisms of the incremental oil recovery. In addition, laboratory and mathematical studies conducted over recent years suggested that mobility control is also...
