Presentation Transcript

  1. AWS AWS uses acoustic well sounding data and fluid levels, to calculate the pressure at midpoint of perforations of oil wells. The program calculates the gas and fluid column pressures separately, and adds or subtracts these, to determine the pressure at MPP. Several different methods are available to calculate the gas column pressure. The results can be plotted, checked and reported on a well, group, pool or total basis.

  3. Well Data • Wells are defined with a pool, group and a lease. • Basic Data: Well name, UWI, group and lease. • Elevations: KB, CF, Perforations, Tubing, and Casing. • Fluid shots: Type of test, date, casing / tubing pressure, watercut and fluid level. AWS, Sirius Petroleum Software
