Application of Pressure Test Analysis in G Oilfield Development Appraisal in Niger

G Oilfield of Niger belonged to a complicated fault block reservoir with both oil and gas in multiple pressure systems.Reservoir appraisal faced the challenges of uncertain gas cap area,uncertain reserves,hence it was difficult for making right development decisions in so short time.RFT pressure test data could be utilized determine fluid properties and fluid contacts and predicting reservoir distribution ranges through the evaluated pressure systems.Its successful use in G Oilfield indicates that the result of the pressure evaluation speeds up the progress of reservoir appraisal.It provides an important basis for development decision making when the oilfield is turned to the development stage.
