The purpose of the re-entry was to perforate the intervals with potentially productive sands, and increase the level of production of natural gas, according to the company.
It was expected the proposed re-entering of the Dahlstrom No 1 well would reduce the hydrostatic weight of the water in the well, which in turn could lead to production increases of 10 to 15 times the level of output achieved at the time of the announcement.
The pressure was low due to suspected sandlocks (build up of sand in the tubing), however, upon completion of the initial work, the well had 600PSI and finally rose to 1625PSI.
The company estimated about 30+ barrels of sand were removed from the well, which had been about 12 inches thick all along the bottom of the open top tank.
The company reported a total of 17 sandlocks at differing depths in the tubing, which inevitably caused the partial blockage in the well.
