<br />2. Information on the well completion (location of the <br />packer, location of perforations, previous cement work <br />on the casing, size of casing and tubing, etc.) and the <br />results of the previous MIT test should be reviewed by <br />the field inspector in advance of the test. Regional <br />UIC Guidance #35 should also be reviewed. Information <br />relating to the previous MIT and any well workovers <br />should be reviewed and taken into the field for <br />verification purposes. <br />3. All Class I wells and Class II SWD wells should be <br />shut-in prior to the test. A 12 to 24-hour shut-in is <br />preferable to assure that the temperature of the fluid <br />in the wellbore is stable. <br />4. Class II enhanced recovery wells may be operating <br />during the test, but it is recommended that the well be <br />shut-in if possible. <br />5. The operator should fill the casing/tubing annulus with <br />inhibited fluid at least 24 hours in advance, if <br />possible. Filling the annulus should be undertaken <br />through one valve with the second valve open to allow <br />air to escape. After the operator has filled the <br />annulus, a check should be made to assure that the <br />annulus will remain full. If the annulus can not <br />maintain a full column of fluid, the operator should <br />notify the Director and begin a rework. The operator <br />should measure and report the volume of fluid added to <br />the annulus. If not already the case, the <br />casing/tubing valves should be closed, at least, 24 <br />hours prior to the pressure test. <br />Following steps are at the well: <br />6. Read tubing pressure and record on the form. If the <br />well is shut-in, the reported information on the actual <br />maximum operating pressure should be used to determine <br />test pressures. <br />7. Read pressure on the casing/tubing annulus and record <br />value on the form. If there is pressure on the <br />annulus, it should be bled off prior to the test. If <br />the pressure will not bleed-off, the guidance on well <br />failures (Region VIZI UIC Section Guidance ,~35) should <br />be followed. <br />8. Ask the operator for the date of the last workover and <br />the volume of fluid added to the annulus prior to this <br />test and record information on the form. <br />9. Hook-up well to pressure source and apply pressure <br />until test value is reached. <br />
