ITEM 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. ITEM 4b: TPI (Top of Producing Interval). ITEM 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. ITEM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). ITEM 20: True vertical thickness. ITEM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITEM 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). ITEM 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). ITEM 27: If no cores taken, indicate "None".

The sidetrack, 18-31A, will exit the existing 5 1/2" liner from a whipstock in Zone 2 and will target Zone 1 sands. Existing perforations will be cement squeezed past a ~ whipstock set at 8850'MD. 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. Pre CTD Summary 1) Complete integrity testing. .~_ 2) Set mechanical whipsto k"ât 850' MD (-8283ss). 3) Pump a minimum of 0 b s cement past whipstock to shut-off existing perfs.

Commi~on Anchorage On October 28, 1998 you requested an update from Shared Service Drilling regarding Annular Disposal Records from July 25, 1995 through present time. We compared your list with our records and are able to provide you with the following data: · Individual Annular Disposal Logs from the ssD database which coincide with the approved wells on your attached AOGCC Annular Log. The ~SSD records are provided to you in the same order as listed on your log. · There were .some wells on your list which were not injected into. These wells are identified as follows: · Endicott wells 1-03/P-16, 1:65/N-25, 1-59/0-24 · Exploration well Pete's Wicked #1 · Milne Point wells E-22, E-23, F-O1, L-16, J-19, L-25, F-30, L-21, K-38, NMP #1 & #2, K-05, K-02, H-07, K-25, K-37, E-17, F-21, K-30, K-34, K-21i, F-66, K-06, K-54, K-33, F-49i, K-18 · PBU Wells E-38, 18-34, 15-42, 'S-29A, 15-46, B-36, 15-43, 11-38 · The reason many of these annuli were not used is because the waste materials generated from these wells were injected into other approved annuli. Hopefully the injection logs submitted with this letter will clarify this. In addition, please note that our records show: · The wells listed above in italics were permitted but not used for annular disposal. · The wells listed above in BOLD were not permitted for annular disposal. Wells drilled after June 6, 1996 were required by SSD procedure to be permitted with a Sundry Approval (10-403) form. Our records show that no Sundry Approval for Annular Disposal was filed for these wells. Wells drilled between July 25, 1995 and June 6, 1996 were automatically approved for annular disposal with the Permit to Drill. · We also provide .you with a cumulative report from our database of records from July 25, 1995 through the present. From those records, we show the following wells not listed on your report were used for annular dispOsal: ,_Annular Disposal Letter 12/14/98 · Endicott wells i-23/O-15, 1-61/Q-20, 2-40/S-22 · Exploration well Sourdough #3 - ~oo ~4 ,~ - ~t~-oa. 9~'- ~g,~'- tS- / · Mi~e Point wells F-06, H-05, H-06, J'13, L-24 - ~s-o~o · PBU wells-18-30, 18-31, 14~,~-43, E-34, E-36, G- , -33- · ~dividu~ logs ~e provided to you tot these logs ~ woi. · Finally, our records show that the B-24 outer annulus was left open (see attached correspondence) Thank you for the opportunity to provide clarity to these records.

As discussed this morning we propose setting three plugs in this well as detailed in the attached form. This will allow us to retain the wellbore for potential future sidetrack or service well use. We would like to keep the well's 9-5/8" x 7" annulus available for the injection of liquid wastes. There are no other well annulii on thispad for injection. The annulus for MPB-24 was approved for injection as part of the permit dated 25 January 1996. The annulus will be freeze protected before moving the rig. Thank you for your help in this matter.

Fluid Handling: All drilling and completion fluids can be annular injected. Request to have well DS 18-31 for annular pumping. Request to AOGCC for Annular Pumping Approval for DS 18-31: 1. Approval is requested for Annular Pumping into the DS 18-31 10-3/4" x 7-5/8" casing annulus. 2. As referenced in Area Injection Order #4, there are no drinking water aquifers in the Prudhoe Bay Field Eastern Operating Area (including the Lisburne Oil Pool), as the average level of Total Dissolved Solids (TDS) at the ambient water within the proposed project area is above 10,000 ppm. There are no domestic or industrial use water wells located within one mile of the project area. 3. The 10-3/4" casing shoe is set at 3680' MD (3678' TVD) which is below the Permafrost and in shale formations in the Sagavanirtok above the Ugnu Formation. 4. The burst rating (80%) for the 10-3/4" 45.5# NT-80 casing is 4170 psig while the collapse rating (80%) of the 7-5/8" 29.7# L-80 casing is 3830 psig. The break down pressure of the-Ugnu formation is 13.5 ppg equivalent mud weight. The Maximum Allowable Surface Pressure while annular pumping is calculated according to the following equation and is 2465 psi for a 10.0 ppg fluid in this well (Assumes worst case in which 7-5/8" casing is filled with gas). MASP = 3830 psig - ((fluid density ppg - 1.9) X 0.052 X 10-3/4" Casing Shoe TVD) 5. A determination has been made that the pumping operation will not endanger the integrity of the well being drilled by the submission of data to AOGCC on 7/24/95 which demonstrates the confining layers, porosity, and permeability of the injection zone. 6. The cement design for this well ensures that annular pumping into hydrocarbon zones will not occur.

As the attached AOGCC Diverter Systems Inspection Report form indicates, the diverter system was in compliance. A tall spool had to be installed to elevate the vent line above the flow lines. The 120' of vent line was necessary to extend a safe distance beyond the Production Module directly behind the rig. Doyon did an excellent job of solving the Flow Line and Production Module clearance problem at this location.

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 permitling 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.

Drilling Hazards: · Minor gas zones have been encountered around the K5 (7425' TVDss) to HRZ interval. · The Put River is a gas bearing sand at 7950' TVDss, It is not well developed in this area and is probably in pressure oommunioation with the Sadelroohit. The required mud weight should be 9.8-10.2 PPg. · The Sag River may be overpressured in this area, The required mud weight should be 10,1 - 10,2 ppg, · Gas zone from Top of ,Sag River to the current GOC. · The target is on the downthrown side of a SW-NE trending fault that has about 50-80' of throw, Standoff from the fault at the base of the Sadelrochit is 200-400'. ,.~tlt._ 7_5 '~995 Alas~ 0ii & 6as Cons.
