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 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 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).

Sundry approval is requested for Prudhoe well 18-24AL2. The pazent wellbore, 18-24 was drilled as a rig sidetrack in May 1995 with a slotted liner completion. The well produced very lift a oil and a second slotted liner leg (18-24AL1) was drilled with coil in October 1995. This additional leg restored the well to full-time status for a year and a half, followed by almost 2 yeazs of cycling. In May 1999, an IBP, sand and to its current location. Although the well was named 18-24AL2, there is only one leg currently open and it is not possible to return to the parent wellbores. 18-24AL2 has 775' of Z1A perfs open, and required gas lift to flow for the first 2 years of production. After 3-1/2 yeazs of full-time production, the well was choked back in an effort to control the GOR and then monthly hot oil treatments were begun to try to boost the rate. The effect of choking back this well was a negligible impact on gas rate paired with an immediate 200+ bopd oil rate impact. Ultimately, the higher backpressure associated with the lower choke setting dropped the oil rate to an average of less than 400 bopd, and finally the well would no longer produce liquids. After being shut in for almost 3 years for no flow, aloes-pressure test was performed that brought in about 200bopd. This test demonstrated the well's sensitivity to choke setting but was not a high enough rate to keep in competitive with the current GPB well stock. Mechanically the well is in sound condition. It passed it's pressure testing (MITIA and MITOA) and had a caliper run in April 2008. The caliper showed the tubing to be in very good condition with no significant areas of wall penetration or cross-sectional loss noted. The 5-1/2" liner is in slightly worse condition with 40-50% penetrations noted in 5 joints. The liner is still in sufficient condition to sidetrack. 18-24A has been shut in for almost 3 years due to lack of fluid production. Although aloes-pressure, open choke test showed the well to be capable of producing 200+ bopd, that rate is not sufficient for the well to be competitive with the current GPB well stock. 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-Rig Work: 1. MIT-IA, and OA. 2.

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 permitting determinations are made. The permit is for a new wellbore segment of existing well 18-24A, Permit No. 95-33, AP! 029-21952- 01. Production should continue to be reported as a function of the odginal APl number stated above. 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. Notice may be given by contactin ~ mission petroleum field inspector on the North Slope pager at 659-3607. . · BY ORDER OF THE COMMISSION /enci c: Dept of Fish & Game, Habitat Section - w/o encl Dept of Environmental Conservation - w/o encl STATE OF ALASKA ALASKA OIL AND GAS CONSERVATION COMMISSIL)N PERMIT TO DRILL 20 AAC 25.005 la.
