Cyclic steam stimulation effect on skin factor reviewed case study

摘要

High oil viscosity is a major concern for recovery from heavy oil reservoir, Introducing heat to the formation has proven to be an effective way improves mobility. Heat transfer to the oil and reservoir rock, this spread is good for recovery. Thermal recovery involves well-known techniques such cyclic steam stimulation which actually affect the nearby well area, Heavy oil reservoir which uses the thermal techniques is a candidate for the property changing after the technique. Fula North East (FNE) Sudanese field which located in the northeast of Fula sub-basin. According to the development program of FNE, Bentiu layer of (Bentiu group) is the targeted reservoir. The pressure gradient is 285.65 psi/100m, perforation intervals is 540-533 m the average oil production rate of single well by applying the cyclic steam stimulation (CSS) 236 bbl/d. For well-Q, (one of the hot wells) to void the bottom water the average production rate is 191 bbl/d. By comparing the skin effect in the well-Q in this case and comparing to the properties of the key well results showed there is slightly change.
