IreM 1a: 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. IreM 4b: TPI (Top of Producing Interval). IreM 8: The Kelly Bushing elevation in feet above mean low low water. Use same as reference for depth measurements given in other spaces on this form and in any attachments. IreM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). IreM 20: True vertical thickness. IreM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. IreM 23: 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).

The ftT only made it to 9.5ppg before it started taking some fluid. We ran he numbers and this still gives us anirt~inite kick tolerance at 9.5ppg. I wanted to give you the notice since the hermit was submitted showing a 10.Oppg FIT. In reality, we should have only submitted the permit with a 9.5ppg FIT. The 6-1 /8" production hole is only 500' for this well and our planned ECD's at the shoe should only reach 9.4ppg with a cuttings load. If you have any questions or need further clarification please give me a call or ~-mail using the contact information listed below.

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. When providing notice for a representative of the Commission to witness any required test, contact the Commission's petroleum field inspector at (907) 659-3607 (pager).

THIS WELL WAS DRILLED FROM A WHIPSTOCK IN THE 16-06 WELLBORE. THE TOP OF THE WHIPSTOCK WAS AT 6712'MD/6385'TVD. 4. THE PURPOSE OF MWD RUN 1 WAS TO POSITION THE WHIPSTOCK, MILL THE WINDOW, AND DRILL A BIT OF RAT HOLE. 5. MWD RUNS 1-3 COMPRISED DIRECTIONAL AND DUAL GAMMA RAY (DGR) UTILIZING GEIGER-MUELLER TUBE DETECTORS. MWD RUN 2 ALSO INCLUDED PRESSURE WHILE DRILLING (PWD). RUN 3 ALSO INCLUDED ELECTROMAGNETIC WAVE RESISTIVITY- PHASE 4 (EWR4). UPHOLE TIE-IN SGRC DATA ACQUIRED WHILE RIH AFTER A SHORT TRIP DURING RUN 2 WERE MERGED WITH RUN 1 MWD DATA. 6. LOG AND MERGED DIGITAL DATA ONLY (LDWG) WERE SHIFTED TO A CASED HOLE GAMMA RAY LOG RUN IN 16-06 ON 7 MAY 1981. LOG HEADER DATA RETAIN ORIGINAL DRILLER'S DEPTH REFERENCES.

MWD RUNS 1-3 REPRESENT WELL 16-06B WITH API#: 50-029-20584-02. THIS WELL REACHED A TOTAL DEPTH (TD) OF 12100'MD/9172'TVD. SROP = SMOOTHED RATE OF PENETRATION WHILE DRILLING. SGRC = SMOOTHED GAMMA RAY COMBINED. SEXP = SMOOTHED PHASE SHIFT-DERIVED RESISTIVITY (EXTRA SHALLOW SPACING). SESP = SMOOTHED PHASE SHIFT-DERIVED RESISTIVITY (SHALLOW SPACING). SEMP = SMOOTHED PHASE SHIFT-DERIVED RESISTIVITY (MEDIUM SPACING). SEDP = SMOOTHED PHASE SHIFT-DERIVED RESISTIVITY (DEEP SPACING). SFXE = SMOOTHED FORMATION EXPOSURE TIME.
