2. 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.
