~~ <br />Test Pressure <br /> <br />To assure that the test pressure will detect significant <br />leaks and that the casing is subjected to pressure similar to <br />that which would be applied if the tubing or packer fails, the <br />tubing/casing annulus should be tested at a pressure equal to the <br />maximum allowed injection pressure or 1000 psiq whichever is <br />less. The annular teat pressure must, however, have a difference <br />of at least 200 psiq either greater or less than the injection <br />tubing pressure. Walls which inject at pressures, of less than <br />300 psiq must test at a minimum pressure of 300 psiq, and the <br />pressure difference between the annulus and the injection tubing <br />must be at least 200 psi. _ <br />Test Criteria <br />1. The duration of the pressure test is 30 minutes. <br />2. Both the annulus and tubing pressures should be <br />monitored and recorded every five (5) minutes. <br />3. If there is a pressure change of 10 percent or more <br />from the initial test pressure during the 30 minute <br />duration, the well has failed to demonstrate mechanical <br />integrity and should be shut-in until it is repaired or <br />plugged. <br />4. A pressure change of 10 percent or more is considered <br />significant. If there is no significant pressure <br />change in 30 minutes from the time that the pressure <br />source is disconnected from the annulus, the test may <br />be completed as passed. <br />Recordkeeping and Reporting <br />The test results must be recorded on the attached form. The <br />annulus pressure should be recorded at five (5) minute intervals. <br />Tests run by operators in the absence of an EPA inspector must be <br />conducted according to these procedures and recorded on the <br />attached form or an equivalent form A pressure recording chart <br />documenting the actual annulus test pressures must be attached to <br />the submittal. The tubing pressure at the beginning and end of <br />each test must be recorded. The volume of the annulus fluid bled <br />back at the surface after the test should be measured and <br />recorded on the form. This can be done by bleeding the annulus <br />pressure off and discharging the associated fluid into a five <br />gallon container. The volume information can be used to verify <br />the approximate location of the packer. <br />Procedures for Pressure Test <br />1. Scheduling the test should be done at least two (2) <br />weeks in advance. <br />
