Good work. Guy Schwartz Senior Petroleum Engineer AOGCC 793-1226 (office) 444-3433 (cell) From: Phillips, Ron [mailto:Ron.Phillips@bp.com] Sent: Tuesday, June 22, 2010 9:19 AM To: Schwartz, Guy L (DOA) Subject: RE: Z-16A report (PTD 192-012) ~; .+~,~~~f.~ ~~ `_ er ~ ~~~~ yr: Guy Schwartz, Sorry it took a little time to find the correct person that was on tower 3/28/10. The Nordic 2 tourpusher said, "The problem was a failing 3" shock hose on the kill side. We had found some rubber at the shaker and after inspection of the 3" shock hose, it was determined to be shedding internally. We then rigged down the 3" flexible kill hose and replaced it with 3" hardline with Graylock clamps. At no time have we ever used threaded 1502 type connections in either our choke or kill lines." The Nordic 2 WSL amended the openwells report to reflect that the hardline had graylock connections. If you need more information please call or email. Thanks, Ron Phillips Coil Tubing Drilling Engineer Alaska Drilling & Wells Office (907) 564-5913 From: Schwartz, Guy L (DOA) [mailto:guy.schwartz@alaska.gov] Sent: Friday, June 04, 2010 9:35 AM 6/28/2010 Page 2 of 2 To: Phillips, Ron Cc: Regg, James B (DOA) Subject: Z-16A report (PTD 192-012) Ron, As I was reading the drilling report for Z-16 I noticed on 3/28/10 on the initial BOP rigup that the shell test had mentioned a failed PT on the Kill line. It appears that it was replaced with a new section but that also failed. Finally "hardline" was installed and passed a pressure test. This happened before the official witnessed BOP test. Can you elaborate on the type of pipe used ... was it knock-up 1502 type connections? Regulations require the kill line to be rigid pipe without hammer unions (20 AAC 25.285 (e) There is no mention of this in our BOP report submitted by the inspector.

Z-16 is a conventional waterflood well drilled in 1992. This well has suffered from abnormally low gross fluid rate and low PI even after acidizing and reperforating. This well is no longer competitive for the limited gas lift in the area. After being shut in from 2006 to 2008 it has seen minimal on time recently. REASON FOR SIDETRACK Given the low fluid rates and high water cut Z-16 is a good candidate for a coil sidetrack. The proposed plan for Z-16A is to drill a through tubing sidetrack with the SLB/Nordic 1 Coiled Tubing Drilling rig on or around October 1, 2009. The existing perforations will be isolated by a cement downsqueeze after setting the whipstock, as well as the primary cement job. The sidetrack, Z- 16A, will exit the existing 5-1/2" liner and kick off in Shublik and drill an S shape well in Zone 4. The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack is attached for reference.

I. Supervisor DATE: April 21, 2001 FROM: Lou Gdmaldi, SUBJECT: Petroleum Inspector SVS Tests BPX Z-pad Prudhoe Bay Field Saturday, April 21, 2001; I witnessed the three-month SVS retests on BPX Z pad in the Westem Operating Area of the Prudhoe Bay Field. Merv Liddelow performed the SVS tests today. The test results (one SSV Failure) are noted on the accompanied SVS test spreadsheet. All well houses were in "OK" condition. This was the first experience I have had with the new SV control system on Z pad and found it to operate quite well. The temperatures today were somewhat mild (+15) and it remains. . to be ~seen how.. they will hold up dudng next winter's cold season. Wells Z-5 and Z-8 had slow clOsing SSV's (+ 2 minutes), Merv called the Automation crew and these were being worked on before I left the pad. The pad is being used as a staging area for some pipeline fabrication and has some equipment and material stored on it. This was kept for the most part neat and orderly. SUMMARY: I witnessed the three-month SVS retests on Z pad in the Prudhoe Bay Field. 20 wells, 40 components, One'failure, 2~4% 34 Wellhouse inspections, no problems.

I. Supervisor Jeff Jones, SUBJECT: Petroleum Inspector Safety Valve Tests Prudhoe Bay Unit Z Pad Friday, JanUary 19,.2001' I traveled to BPX's Z Pad in the Prudhoe Bay Field and witnessed surface safety valve system'testing. Merv Liddelow was the BPX representative in charge of testing. As the attached AOGCC Safety_ Val.~e System Test Report indicates I witnessed the testing of 21 wells and 43 components with 6 failures. The pilot on well Z-03 failed to trip and the pilot on well Z-08 was frozen and once thawed it passed a retest but the SSV on this well had an unacceptable closure time (12-min.). The SSV on well Z~18 also had an unacceptable closure time (15-min.) and the SSV's on wells Z-22B and Z-24 failed to pressure test. The high failure rate on Z Pad requires it be placed on a 90- day test interval. Mr. Liddlow indicated to me today that all failures have been repaired except the slow SSV closure of wells Z-08A and Z-18. The hydraulic lines on these wells need to be flushed and he has arranged for the maintenance crew to perform the work. Wellhouse inspections were conducted on the 21 wells tested with no exceptions noted. Summary: I witnessed SVS testing at BPX's PBU Z Pad. 21 wells, 43 components, 6 failures. 13,9% failure rate. 21 wellhouse inspections conducted. .A.ttac. hme,nt: SVS PBU Z Pad 1-19-01 JJ Alaska Oil and Gas Conservation Commission Safety Valve System Test Report Operator: BPX Operator Rep: .Merv Lidde. low AOCff2C Rep: ' 'jeff Jones Submitted By: Jeff Jones Field/Unit/Pad: PBF/PBUf-Z Pad Separator psi: LPS 159 Date: 1/19/01 ' ' " ' .......

The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness, the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

PBU I The Drilling fluid program will consist of an 8.5 - 10.2 ppg spud mud in the 13- 1/2" hole, a 9.5 - 10.5 ppg water base mud in the 9-7/8" hole and a 9.3 ppg water based mud in the 6-3/4" hole. Drill 13-1/2" hole to 3000'. Run and cement 10-3/4", 45.5 #,'NT-80LHE Buttress casing to surface. Install blowout prevention equipment consisting of 5000 psi W.P. pipe rams, blind rams, and annular preventer. Maximum possible bottomhole pressure is 4390 psi at 8800' TVDss based on original reservoir pressure. Maximum possible surface pressure is 3330 psi based on a gas column to surface from 8600' TVDss and an oil column to 8800' TVDss. A formation leak-off test will be performed 10' below the 10-3/4" shoe. Directionally drill 9-7/8" hole to the 7-5/8" casing point above the top of Sag River Sandstone. Run a 7-5/8" casing string of 29.7# NT-95HS NSCC to within 10' of 9-7/8" TD and cement with Class G cement around the 7-5/8" shoe. The annulus will be freeze protected by dry crude. Directionally drill the 6-3/4" hole to TD. Run 5-1/2" liner from TD to 250' inside 7-5/8" casing shoe and cement using Class G cement. Clean out to 5-1/2" float equipment. Change over to NaCI completion fluid. Test casing and lap to 3500 psi. Run 7-5/8" production packer on tubing. Set packer 50' above top of liner. A subsurface safety valve with dual control lines will be placed 100' below base of permafrost. Install and test Xmas tree. Displace tubing to diesel. Set and test packer. The well will be perforated after the rig has been released. Fluids incidental to the drilling of a well will be pumped down the 7-5/8" x 10- 3/4" annulus of the well.
