Mr. Dan Jackson <br />Page 2 <br />does not compare closely with the baseline, discontinue the test (reduce pressure <br />by 10 psi and monitor closely). <br />8. If the pressure change compares favorably to the baseline, increase the pressure <br />by 25 psi (to 750 psi) a-hd continue the test. <br />9. Continue to increase by 10 psi increments (from 750-800 psi) and check against <br />the baseline until conditions warrant a reduction in pressure, or, an 800 psig <br />injection pressure is achieved. <br />The data from the step pressure test is provided for your review with this correspondence. <br />The results of the tests indicate that the 800 psi injection pressure for the wells tested <br />caused no formation fracturing. <br />American Soda would like to perform additional step pressure tests to demonstrate that <br />injection pressure can be raised in operating wells, without causing formation fracturing. <br />The next wells we would like to conduct the test on, along with a two (2] week notice are as <br />follows; <br />1. Well 20-12 EPA Permit # C03858-04552 at 8:00 AM on May 13`x, 2002 <br />2. Well 29-23 EPA Permit # C03858-04571 at 8:00 AM on May 15`", 2002 <br />3. Well 20-32 EPA Permit # C03858-04559 at 8:00 AM on May 20`", 2002 <br />4. Well 20-35 EPA Permit # C03858-04561 at 8:00 AM on May 22nd, 2002 <br />Based on the previous tests, we would like to modify the step pressure test procedure with - <br />the following change: <br />Have all step pressure increments between 700 - 800 psi ,be 25 psi versus <br />two steps at 25 psi and five steps at 10 psi. We will keep the one hour shut <br />in period for each pressure step. <br />Sincorahi_ <br />alth <br />Cc: Field Office Manager, BLM <br />White River Resource Area <br />73544 Highway 64 <br />Meeker, CO 81641 <br />Allen Sorenson <br />Colorado Division of Minerals and Geology <br />Department of Natural Resources <br />1313 Sherman St., Room 215 <br />Denver, CO 80203 <br />
