Well names currently include a forward slash "/" followed by an obsolete bottom hole location designator. HAK would like to retain the well number as well as the "A, B, C...." sidetrack designations but remove the "/suffix". For example, "DUCK IS UNIT SDI 1-09A/L21" would become "DUCK IS UNIT SDI 1-09A". The attached spreadsheet includes original and new names for all Duck Island wells. While performing the review of Duck Island well names, HAK found a single well, "DUCK IS UNIT SDI 4-20/M35" (PTD# 1861730), that should also be modified to include an "A" label to reflect the fact that the well is a sidetrack from the original "DUCK IS UNIT SDI 4-20/T34" (PTD # 1861500). The original wellbore, abandoned 10/13/1986, was sidetracked to a new bottom hole location completed on 9/9/1987. This well appears to be one of the first sidetracks performed at Endicott. While the bottom hole code was changed, no letter was added to reflect the sidetrack. "DUCK IS UNIT SDI 4-20A" is also included on the attached spreadsheet.

PO Box 196612 Anchorage AK 99519 Re: Cancelled or Expired PTD's. Dear Gunkel: The Alaska Oil and Gas Conservation Commission ("AOGCC") approved the following referenced permit to drills. The AOGCC has a long-standing policy of releasing cancelled or expired permits two years from the date the application was approved by the AOGCC. The following files are scheduled to be released October 1,2001.

Our adopted conventions for assigning APl numbers, permit numbers and well names did not specifically address expired or cancelled permits. This omission has caused some inconsistencies in the treatment of these kinds of applications for permit to drill. Operators have asked us to adopt formal procedures for this class of permit application in order to prevent future database disparities. If a permit expires or is cancelled by an operator, the permit number of the subject permit will remain unchanged. The APl number and in some instances the well name reflect the number of preexisting redrills and or multilaterals in a well. In order to prevent confusing a cancelled or expired permit with an active well or multilateral these case sensitive well identifiers will be changed for expired and cancelled applications for permits to drill. The APl number for this cancelled or expired permit is modified so the eleven and twelfth digits is -95. The well number for a cancelled or expired permit is modified with an appended XX. EXPIRED PERMITS ARE RELEASABLE 2 years from the date on the application was issued by the commission, unless the operator ask for extended confidentiality. AOGCC database has been changed to reflect these changes to this permit.

The formation also has the potential for lost circulation (see Geologic Prognosis for faulting details). Lubricant additions (see above) should be utilized if torque and drag become troublesome, and after extensive testing of mud on location. Flex collars should be utilized in the BHA to minimize potential differential sticking. Liquid casing and OM seal should be on location to help combat severe lost circulation. NOTE: See-the Geologic Prognosis for a detailed description of the expected fault locations and sizes. Review the Pad Data Sheet for trouble highlights throughout MPI history. Well Control: Well control equipment consisting of 5,000 psi W.P. pipe rams, blind rams, and annular preventer will be installed and is capable of handling maximum potential surface pressures.

We will have to abandon the existing perforation in the 3-21/L-34 well by pumping cement down coil-tubing, setting a through tubing whipstock and kick off through the 7" casing to the K-35 BHL utilizing the 2.875" liner design. We will not pull the existing production packer or tubing in this well. The 2.875" liner length will be _+ 1886 feet, with the top of the liner hanger back into the 4.5" production tubing. The existing 6 valve (ultra)slimhole (4.5" x 1.5" for 9.625" casing) GLM design for the completion on a 4.5" L-80 tubing design with a X/XN nipple profile. Directional Plan: The directional plan for the 3-21a/K-35 well consists of kicking off with a whipstock and conventional BHA's fOr the Kekiktuk Flow sands. Current plans call for up to 8°/100' doglegs in this section, but this may be adjusted pending results during the drilling process. After sidetracking, drilling the tangent at 81° degrees, and steering directionally back into the Sands with 74° of inclination, the well will be drilled to _+13,947 MD (10,256' TVD). Ensure that any and all tolerance lines are not crossed to avoid policy violations. Please coordinate this through both the Operations Drilling Engineer and the Endicott Drilling Superintendent. There are not any known close approaches which require wells be shut in. Any BHA's indicating less than required BUR should immediately be pulled for a more aggressive assembly. Recommended BHA's All motors should NOT be jetted to account for the proposed flowrate and motor performance. Hole conditions and directional objectives should dictate actual flowrates. As mentioned previously, flex collars should be utilized in the 8.5" hole sections to minimize potential differential sticking. We will be using bent housing motors with either 7/8 for a roller cone or 5/6 rotor/stator configurations for PDC bits IF run. Sperry proposed BHA's are attached, however the actual BHA with motor design, MWD/LWD tool configuration, MWD battery life, bit hydraulics will be discussed at the daily wellsite meeting. Directional Survey Program The survey program for 3-21a/K-35 calls for use of Sperry's SOLAR MWD surveys the entire well. Because of Sperry's standard practice of changing the MWD probes after every bit run, an electronic single shot (ESS) will not be needed, and a gyro is not warranted. Close attention to JORPS is required, with the use of checkshots and survey data validation. Bit Program We will kick off the in the HRZ with a conventional directional BHA and PDC bit, which should make it to the Kekiktuk. After milling the window, a 3.75" tangent section is planned to the Kekiktuk. The penetration rate will vary due to the variable lithology, but these bits have proven durable enough to drill through most of this interval. However, if there is any indication of bit failure such as torque spikes, the bit should be pulled at the descretion of the rigsite team. Recommended Jet Sizes Expected Interval Bit Type Flowrate HSI Casing Section Standard Window Mills 90 - 120 gpm 3.75" Kickoff STAR 09 90 - 120 gpm 3 x 12 2.9 - 4.8 3.75" Tangent PDC Bit 90 - 120 ~lpm 3 x 15 2.9 - 4.8 3-21a/K-35 Drilling Permit 1/26/98 Directional Plan #2 NOTE: Real time rigsite information such as condition of bits previously pulled, hole conditions, drilling fluids, downhole motor constraints (if any) will be instrumental in actual final bit selection. Mud Program: We will use LSND on this well to both mill the window and drill to TD. There should not be any additions of any lubricants in this well without extensive testing of the actual fluid on location. A new Gel/Biozan polymer will be used for milling the window. Ditch Magnets should be used and WEIGHED to ensure metal cuttings removal. Rheology control can be maintained using Gel and Biozan polymer. At this time raise the LSR YP to the recommended range using Biozan. Biozan sweeps should be pumped to assist in hole cleaning and to prevent the build up of cuttings beds. Mud sweeps are essential for good hole cleaning while drilling. Additions of 3#/BBL each of Baranex and Barotrol should be maintained throughout this well. This treatment should result in an HPHT of <14 which is our target. Maintain the pH in the 9-9.5 range using caustic soda. If torque problems arise, a treatment of 1- 2% Lubetex should be used. If the torque persists, the ERD lubricant mix should be evaluated. The LSND mud will be taken to TD on this well. Maintain the weight at the density required in the intermediate section. The Barotrol and Baranex treatments should be maintained at 3#/bbl untill the ICP. The APl filtrate should be reduced to the 4 cc range with PAC and starch. This will reduce the chances of differential sticking and reduce filtration invasion. Tripping Practices / Stuck Pipe / Hole Cleaning Tripping should be undertaken with caution due to swabbing possibilities with high viscosity fluids in the tight annular clearance. The bottom hole pressure is approximately 4800 psi (7.4 to 9.5 ppg ). It is recommended that mud weights be maintained in the 10.2 to 10.4 ppg range to control the hydrocarbon intervals, maintain shale stability and minimize the possibility of differential sticking. Faulted intervals may require additions of LCM prior to tripping to insure that the hole remains full at all times. Keep the pipe moving and have an ample supply of lost circulation materials on hand. Baroid recommends utilization of Iow viscosity sweeps to assist with hole cleaning and to minimize the formation of cuttings beds on the Iow side of the hole. No potential hazardous levels of H2S are anticipated in the 3-21a/K-35 well. There have been H2S reading on offset SDI wells of over 1000 ppm. Ensure rig gas detectors are calibrated prior to N/D tree and/or circulating to kill the well. 3-21a/K-35 Drilling Permit Directional Plan #2 1/26/98 Logging Program: Logs: 3.75" Hole Curve and Tangent MWD-GR DPC logs In open hole Slim hole QUAD Combo Cased Hole: NA Sample catchers and a wellsite Geologist are planned to be used while drilling reservoir. Casing and Cementing This TTRD sidetrack will require a 2.875" 6.4# L-80 liner to be run across the entire interval. This will be hung off in the 4.5" tubing at 12,061 feet. Ensure that prior to running liner that the hole is in good condition and that the mud has been conditioned to run casing. Before POH to run liner spot lubricant across the open hole section. If this is considered essential to getting the pipe to bottom ensure that adequate lubricant testing has been performed prior to doing this. Also, consideration must be given to a hole opener trip prior to running liner if hole conditions suggest that there may be problems running pipe. This liner will use STL connections to allow rotation and reciprocation. Special equipment will be required for this including XO for safety valve and having the liner hanger cut with a STL connection on bottom. The liner should be filled every 5 joints, and circulated prior to going into open hole. Any problem intervals identified while drilling, such as ledges, will require special care while running casing through. The liner will require 1 straight blade centralizers on every other joint to the window. If the liner starts to packoff in the open hole, establish circulation and try to wash through. Do not continue to run casing without circulation. If necessary, we will pull casing and make a wiper trip prior to running the liner. The liner running procedure in the detail section should be reviewed. The cementing program is designed place cement to at least1000 feet above the top of the Kekiktuk formation, or to the liner hanger. The approximate volume will be 68 sacks of Class 'G' with additives as speficied in the casing detail section. Cementing operations at Endicott are continue to be critical with the advancement of both the waterflood and gas fronts. Close attention to detail for this part of the well is critical for the economical success of our drilling program. DPC Perforating This sidetrack well will require a DPC perforating across the intervals picked from LWD logs. 3-21a/K-35 Drilling Permit Directional Plan ~¢2 1/26/98 SDI WELL ,3-21A / K-35 (Wp2) - SURFACE & DOWNHOLE LOCATIONS 1/27/98 ITEM NAME COMMENTS ALASKA STATE PLANE ZONE 3 (NAD 27) I DECIMAL DEGREES (NAD 27) S & E SEC LINE OFFSETS SECTION, TOWN., i NEAREST SECTION LINE OFFSETS NO.
