They were pressure tested and ready when I arrived. Checked the gauges and paper work out. Good test. Down hole temp was 120 degrees and they heated the diesel to as close to that as possible but it ended up 130 degrees going in. Which I believe accounts for some of the initial pressure loss in the first 15 minutes.

Apply to 4 -year AOGCC test requirement to reset testing clock. PBU 11 -26 (PTD #1861340) Initial AOGCC witnessed MIT -IA performed 01/28/2012 post rig work over operation to repair TxIA communication and PC leak. PBU Z -102 (PTD #2070500) 4 -year AOGCC MIT -IA was due while well was secured for drilling operations on Z- 116. MIT -IA performed 01/28/2012 to put well in compliance to allow injection. The following two wells on your list do not have AOGCC witnessed MIT -IA's performed: PBU W -216 (PTD #2071680): Last AOGCC MIT -IA was performed 10/02/2008 for evaluating IAxOA communication witnessed by Mr. John Crisp. The MIT -IA form was submitted noting the interval as "0". BP will complete a 4 -year AOGCC witnessed test prior to 10/02/2012. I have attached the MIT -IA form pulled from the AOGCC website for reference. PBU P WW1 -2A PTD #1901180): Last 4 -year AOGCC MI - A was performed 01/04/2008. A non - witnessed MIT -IA was performed on 07/19/2009 at which time the test was incorrectly flagged as a witnessed test in our database. A witnessed test will be immediately scheduled (weather permitting) and the test data submitted to the AOGCC as soon as completed. Please call if you have any concerns or require further information.

Run open hole logs. R/D E-Line. 3. Run and cement 9-5/8" casing. 4. Clean out 9-5/8" to float collar. Test 9-5/8" casing to 3000 psi. Displace cement with 8.9 ppg NaCh Retest casing to 3000 psi. 5. R/U E-Line. Run CET / CBT / GR. R/D E-Line. 6.Run Baker 9-5/8" x 5-1/2" packer on drill pipe. Set packer at 3200'. Test packer to 3000 psi. Lay down drill pipe. 8.Run 7" seals, tubing, and SSSV. 9. Displace well with diesel treated with corrosion inhibitor. 10. Land tubing. Test tubing to 3000 psi. Test packer and casing to 3000 psi. 11. Set BPV. Nipple down BOP, nipple up tree. Test tree to 5000 psi. Secure well. 12. Release rig. 13. RAJ E-Line. Run GCT gyro. Perforate well. R/D E-Line. NOTE; a. Excess non-hazardous fluids developed from the well operations and as necessary to control the reserve pit fluid level will be pumped down the 9-5/8" x 13-3/8" annulus. The annulus will be left with a non-freezing fluid during any extended period. The annulus will be sealed with 300 sx of cement followed by Arctic Pack. b. There are no surrounding wells within 200 ft. of the proposed well. c. The drilling fluid program and surface system will conform to the regulations set forth in 20AAC25.033. d. Maximum surface pressure is based on BHP and a full column of gas to TD (0.10 psi/fi). e. Based on previous logs, no potential productive zones are antidpated above 3500' TVD. f. No potential hazardous levels of H2S are antidpated in this well.
