bentonite pellets. A cement (Portland type II with 5% bentonite) plug was then <br />placed from a depth of 515 feet to 585 feet. <br />4.0 PERMEABILITY PACKER TESTS <br />Permeability tests were conducted in each of the three new monitor wells. <br />These tests were constant -head packer tests run in the following manner. Once <br />the portion of the formation to be tested was penetrated by the drill bit the hole <br />was thoroughly flushed and cleaned. The packer was then attached to the <br />bottom of the drill string and lowered into the hole. The packer was then <br />positioned and inflated in order to isolate the strata to be tested. The equipment <br />set -up is shown in Figure 5. <br />Water was then pumped into the cavity until a selected pressure was <br />attained and stabilized. The water flow was monitored until it remained constant. <br />These static conditions were monitored for a period of 20 minutes at which time <br />the pressure and flow were recorded. Permeability was then calculated from the <br />data obtained from the tests. The Results are presented on <br />4.1 CM93 -1 <br />An interval, within the Summerville formation, was packer tested in this <br />well (Table 1). The depth of the test was 183 feet to 199 feet. A pressure of 270 psi <br />was attained without any observable water "take" by the formation. In order to <br />estimate a maximum permeability for the formation a flow rate of 0.025 gal /min <br />was used in the permeability calculations. This rate was used as it was the lowest <br />detectable flow rate with the equipment used. A permeability of 8.0E - 08 cm /sec <br />was calculated for this interval in the Summerville formation. It should be <br />understood that the calculated permeability value is only an estimate and in <br />actuality could be much lower. <br />16 <br />
