Presentation Transcript

  1. Gas Buildup Analysis GasBU uses standard buildup tests from individual wells and performs a buildup analysis using various methods. The program allows for easy determination of Reservoir Permeability, and Skin Effect using graphical and numerical analysis. Results are summarised by well, group, pool, lease and company.

  2. GasBUAgenda • Well data • Pool data • Lease data • Gas analysis data • Special Features, System Options, Methods and Correlations • Output Reports and Graphs • Demo • Questions GasBU, Sirius Petroleum Software

  3. Well Data • Wells are defined with a pool, group and a lease. • Basic Data: Well name, UWI, group and lease. • Reservoir Data: Netpay, porosity, water saturation, drainage radius, wellbore radius, equivalent production time and extended gas flow rate.. • Test Data: Shut-in Pressure and shut-in time..
