This same design will be used as a starting point for the Teapot Tensleep treatments. A small amount of 3,000 ppm could be used up front just to test injectivity. Treatment Volume Based on Marathon s experiences in the Big Horn Basin, a treatment volume based on 25 bbls per foot of perforated interval seems to be a prudent starting point. This number should be adjusted since the well spacing on the Big Horn Basin treatments was 5 acres and the Teapot Tensleep wells are 10 to 20 acre spacing. If 50 bbls per foot were used, a 2500 bbl treatment would be an appropriate volume for the first treatment.
Dehydration is a function of time and pressure.
Both of these variables should be minimized. Consequently, the rate should be maximized at a reasonable pressure. In no case should this be exceeded. It is recommended to treat the well at the maximum rate possible at a bottom hole treating pressure of 3100 psi. Surface pressure can be increased to account for friction pressure loss in the tubing during treatment.
