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 vaxiance. 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. When providing notice for a representative of the Commission to witness any required test, contact the Commission's petroleum field inspector at (907~5~9-3607 (pager).

S-400A Permit to Drill Application Page 3 ~ Well Control ~ Well control equipment consisting of 5,000 psi working pressure pipe rams (2), blind/shear rams, and annular preventer will be installed and are capable of handling the maximum potential surface pressures. Based upon calculations below, BOP equipment will be tested to 3,000 psi.

Disposal No annular injection in this welL Cuttings Handling: No returned solids from this well may be considered EPA exempt until further investigation. Therefore, until further clarification solids must be stored at CC2A (or T- Pad) until a Class 1 solid disposal well is permitted, or until the returned cuttings can be designated as Class 2. Fluid Handling: All returned fluids not re-used or recycled must be considered either hazardous or class 1 waste. Only freeze protect fluids have been identified as potentially hazardous, therefore diesel and/or methanol recovered from the well should be recycled or reused as freeze protection at the end of the well construction. Returned acid and cement contaminated fluids must be neutralized to pH between 2.0 and 12.5 and sent to class 1 disposal. S-400A Permit to Drill Application Page 4 i • Drillinq Hazards and Continqencies POST THIS NOTICE IN THE DOGHOUSE I. Weii Control A. BOP equipment will require no more than 3000 psi pressure test due to the low potential shut-in pressure of this relatively shallow wel1. Gas hydrates in the SV-1 are mentioned on the pad data sheet as well as coal and gas at the top of the Ugnu 4 interval. 11. Lost CirculationlBreathing A. Lost circulation is not anticipated prior to the gravel pack completion in the non-depleted reservoir targets. Ample brine will be on location to manage any losses that may occur as LCM may not be used while drilling this well. ffl. Kick Tolerancellntegrity Testing A. Due to the relatively high KOP in this well, the kick tolerance will be just over 50 bbls with an 11.4 ppg FIT. Less than 11.4 ppg frac gradient will require drilling manager approval prior to drilling ahead. 10.4 ppg F{T is the minimum required for a 26 bbl kick tolerance and AOGCC permit.. B. Integrity Testing IV. Stuck Pipe A. This sidetrack will kick off in, and target, unconsolidated sands. Though these intervals have little history of contributing to stuck pipe, the potential remains if hole cleaning suffers. Maintain specified mud properties and monitor ECD readings for signs of hole loading. VI. Hydrogen Sulfide A. S-PAD is designated as an H2S site; Standard Operating Procedures for H2S precautions should be followed at all times. H2S levels of potentially lethal concentrations have been recorded on this pad. Perform H2S drills regularly and ensure all personnel are properly training and follow the SOP for H2S. VII. Faults A. No faulting is expected along the planned trajectory. S VIII. Anti-Collision Issues B. All wells pass major risk criteria for close approach. Several nearby wells have less than 80' allowable deviation from plan, however. Consult the anti-collision report for wells of interest afong the planned trajectory.
