OXY May Pit
The survey revealed that the pit maintains consistent depths. The deepest part of the pit
is at the sump and on the southwest corner. All water should drain to the sump area. At
least 90% of the water in the pit can be utilized for a frac.
Suggestions to improve Utilization and Safety:
1. Gauging this will be difficult with no Gauge installed. For a pit this size, we
recommend a digital Hydrostatic sensor to be installed to provide accurate readings.
These readings would provide accurate measurements down to the gallon.
2. The levee in the SE corner is the lowest and overfilling would result at that point.
3. This pit is constructed with 20 mil string reinforced liner and has been sewn at the
seams. These stitches are pulling out in the corners of the pit. Transwater can Heat-
Weld these seams and provide increased strength

Pit can only safely hold 10 more additional ft.
**These numbers are extrapolations based on actual data
**This pit measured 23 ft to the top. Those numbers for levels above 13 ft have been extrapolated to
provide volumes at those increased depths.
