She said that this is rare and we almost always run an MCNL. For Y-33A we only ran a GR/CC1,. Sorry for the mix up and let me know if you need anything else from me. We will hand correct our copy of the 10-407 Completion report to show no MCNL run. Thanks!

We have received the missing data for the PBU B-20A well. I checked it in this morning. At that time, I also looked for the PBU Y- 33A data, but could not find it. I just checked again in case I missed it this morning and it is not in house. Maybe it will come in later this afternoon. At any rate, a couple of us are on the look out for it. The isolation scanner log (run 22-Dec-2011) is the only cement log that we have for PBU Y-33A.

We are currently in discussion to determine the ETA for delivery of the missing Z-116 logs, I'm trying to confirm that the Isolation Scanner sent on the attached transmittal was the Cement log, or if there was another cement log run after. Please let me know if you have any questions and thank you for letting me know that these weren't delivered. Thanks!

TNX for the update. Now for PBU Z-116 API 50-029-23455-00-00. We have not received the OH logs digital nor hard copy paper logs. According to the 10-407 GR, Res, Neu, Azimuthal Density, Caliper, & CBL (CBL needed because it is an injection well) logs were run. We do not have the digital data nor the hard copy paper logs. This well was completed December 2011. Could you please send the missing data to us as soon as possible.

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.

Disposal: • All Class I & II non-hazardous and RCRA-exempt drilling and completion fluids will go to GNI at DS4orPad3atDS6. • Fluids >1% hydrocarbons or flammables must go to Pad 3. • Fluids >15% solids by volume must go to GNI. • Fluids with solids that will not pass through 1/4" screen must go to GNI. • Fluids with PH >11 must go to GNI. Hole Size: • 4.5" From 11,145' MD to 13,636' MD - Expandable Liner Program: • 4.35", 9.3#, MTX-60, R2M-2 Solid Liner Opportunistic setting depth, 150' in length Liner Program: • 3-1/2", 9.3#, 13Cr, STL Solid Liner 10,620' MD — 11,000' MD • 2-7/8", 6.5#, 13Cr, STL Solid Liner 11,000' MD — 13,636' MD • A minimum of 42 bbls of 15.8 ppg cement will be used for liner cementing. (TOC 10,620' MD) • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3,500 psi. • The annular preventer will be tested to 250 psi and 3,500 psi. Directional: • See attached directional plan. Maximum planned hole angle is 103.7°, inclination at kick off point is 60.8°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property— 19,807'. • Distance to nearest well within pool — 775'. Logging: • MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. • Cased hole GR/CCL/MCNL logs will be run. Perforating: • SWS 2" PJ 6 spf pert guns, 1-1/4" CSH work string, & 2-1/16" CSH. • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Anti-Collision Failures: • None. Hazards: • Y pad is considered a H2S pad. Well Y-33 had 350 ppm H2S on 2/23/2011. • Most recent H2S level on Y-33 is 350 ppm recorded on 2/23/2011. • • • The lost circulation ris,. in Y-33A is considered to be mediui,. .iue to open perforations and . fault crossing. Reservoir Pressure: • The reservoir pressure on Y-33A is expected to be 3,384 psi at 8,800' TVDSS. (7.4 ppg equivalent). - — • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,504 psi. - • An EMW of 8.4 ppg for this well will provide 459 psi over-balance to the reservoir. .
