The 4.5" liner is mostly well cemented .., do you have a general idea where you will be perforating this well? That would help me determine if UIC requirments are being met. If you are well below from the 7" shoe with the injection zones you should be ok. Please cc Schomyer and Montague since I don't have their email.

This well is currently a producer that will be converted to WAG injection in the next couple of years. Has there been any progress on this well? Also, please respond to Al Schmoyer or Stuart Montague with your response. I am moving to Cairo to work with the GUPCO group and Al is watching P -Pad until a new PE comes in at the end of August.

Date Monday, June 25, 2012 3:46:28 PM To Schwartz, Guy L (DOA) Cc Subject P -28 Concurrence of Cement Behind Pipe p-U 7-4 0 E 9 To Guy Schwartz Petroleum Engineer Ancrr: Guy, P -28 was a new well drilled in May /June of 2010 and has been on production since July of 2010. The intent of this well is to pre - produce for -3.5 years and then convert it to a WAG iniector, As an infector it will support P -08 and W -08 in addition to a future W -Pad Ivishak well and possibly Sag producers. In Preparation for the future conversion, cement bond logs have been run to confirm proper zonal isolation. ➢ USIT run on 6/8/10 (log run 3 days after cement was in place. DIMs report indicates that cement was displaced with 11 ppq mud. Prior to milling out cement shoe. 11 DPP mud was displaced with 8.5/8.6 ppq Flo Pro, same fluid when USIT was run.) ➢ The second log was a Sonic CBL run after the 4.5" liner was run (6/14/10). This log was run at 1000 psi and 0 psi surface pressures. However, the log run in the 7" casing had to be re- processed by Schlumberger due to miscommunication on how far up the hole the log should be run at the time. Attached below are Schlumberger's analysis about the cement quality In general the intermediate cement job on P -28 is not of good quality, however there are competent sections of cement as listed below. The criteria that I used to determine competent cement was 95% radial coverage of what the tool determined to be cement touching the casing, or the presence of microanulus (also indicating cement bond to the casing.) 12746 -12750 4' 12443 -12453 10' 12422 -12424 2' 12353 -12357 4' 12245 -12252 7' 12236 -12240 4' 12197 -12205 8' 12024 -12027 3' 11515 -11517 2' 11506 -11511 5' https:// ancev02 .soa.alaska.gov/EnterpriseV ault/ViewMessage .asp ?VaultId= 17A3EF6017F... 8/14/2012 P -28 Concurrence of Cement Behind Pipe- Enterprise Vault Archived Item Page 2 of 2 • • 11387 -11395 8' 11369 -11371 2' 11116 -11119 3' 62' of non - continuous bonded pipe was observed.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations.

Terrie Hubble, 564 -4628 Well Number Permit No. / Approval No. Drilling Engineer: Abby Warren, 564 -5480 INSTRUCTIONS General: This form is designed for submitting a complete and correct well completion report and log on all types of lands and leases in Alaska. Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. Item 1 a: Classification of Service Wells: Gas Injection, Water Injection, Water - Alternating -Gas Injection, Salt Water Disposal, Water Supply for Injection, Observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. Item 4b: TPI (Top of Producing Interval). Item 8: The Kelly Bushing and Ground Level elevation in feet above mean sea level. Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13: The API number reported to AOGCC must be 14 digits (ex: 50- 029 - 20123- 00 -00). Item 20: Report true vertical thickness of permafrost in Box 20. Provide MD and TVD for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: If this well is completed for separate production from more than one interval (multiple completion), so state in item 1, and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 27: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut -In, or Other (explain). Item 28: Provide a listing of intervals cored and the corresponding formations, and a brief description in this box. Submit detailed description and analytical laboratory information required by 20 AAC 25.071. Item 30: Provide a listing of intervals tested and the corresponding formation, and a brief summary in this box. Submit detailed test and analytical laboratory information required by 20 AAC 25.071.

This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit.

P -28 Permit Application Page 8 • • DRILLING CRITICAL ISSUES POST THIS NOTICE IN THE DOGHOUSE I. Well Control / Reservoir Pressures: A. Normal pore pressures are expect throughout surface hole drilling operations. Normal ressures are also expected throughout the intermediate hold drilling operations, however, there was Ugnu overpressure encountered in P -24 and P -25 (10.2 ppg required in P -25). Both of these wells were drilled in 1997 where the P -27 well was drilled in 2004 and a 9.8 ppg was used. The current plan is to run with a minimum of a 9.2 ppg in this section of the hole. The Ivishak Zone in P -28 is expected to be under - pressured at 7.2 ppg EMW. This pressure is estimated based on offset well pressures. II. Faults / Lost Circulation / Breathing A. P -28 is expected to cross 4 faults. There is a possible fault crossing in the Upper Kingak that would have a minimal throw (10' -15'). There is three faults in zone, two of which that are expected to be minor crossings and another should be easily detected. Also out past 16250' there is a possibility of intersecting 1 -3 minor faults /fracture zones in which lost circulation risk is considered high. III. Hydrates and shallow gas A. No gas hydrates are anticipated, however, follow good drilling practices in this regard at all times. B. Shallow gas is noted on the pad data sheet for intermediate hole, and gas cut mud is noted for the production hole. P -27 there was no indication of any shallow gas. IV. Kick Tolerance /Integrity Testing A. The Kick Tolerance for the intermediate hole section is 112 bbls with a 11.3 ppg FIT out of the 9- 5/8" window. The production hole section's kick tolerance is infinite with a 9.6 ppg FIT. These given FIT's will be our minimum for kick tolerance, and may increase due to ECD management. B. Integrity Testing Test Point Test Depth Test EMW (1b/gal) type 9-%" 20 -ft minimum from the 9-%" LOT 11.3 window window minimum 7" shoe 20 -ft minimum from the 7" shoe FIT 9.6 minimum V Hydrogen Sulfide A. P -Pad is not designated as a high H2S pad, but standard precautions will be followed at all times.

There may be some differential sticking tendencies across upper sands in the the intermediate hole with the planned 10.6 ppg mud weight in the hole and in the production interval of the well while drilling with the 8.5 ppg plys FloPro, therefore, follow good drilling practices and good casing /liner running practices for both intervals.
