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.

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.
