Mitchell Energy Development Corp. has completed the largest, deepest, and most expensive nitrogen foam fracture job ever undertaken. One of Mitchell's wells, No. 1 stone well in the tight Cotton Valley limestone, had been drilled and completed in 1969, and was producing 50 to 75 MCFD of natural gas. The fracturing process used followed the following steps: sand mixed into gelled water slurry, pumpers raised pressure of sand mixture to 9000+ psi, sand concentration in slurry raised by a special process, foamer added, liquid nitrogen heated under pressure, and the nitrogen/sand/gelled water was blended and injected into the well. The interval treated was between 10,930 and 11,130 ft. The treatment increased production from the well to 1.3 MMCFD. Results demonstrate the stability of the nitrogen foam designed for this well at the given depth and temperature.
