This was discovered while computing the bottom hole location for the Completion Report. Originally Permitted (Incorrectly) Location of well at total depth 4570' NSL, 3869' WEL, SEC. 13, T10N, R14E Should Have Been Permitted Location of well at total depth 4570' NSL, 3869' WEL, SEC. 18, T10N, R15E (or 1193' EWL) This information was listed correctly under Global and Local Coordinates on the directional attachments to the Permit to Drill, but not translated correctly. Additionally because the section was incorrect the ADL changed as well. I apologize for any inconvenience this may have caused. Please let me know if there are any further action required.

To: Date: From: Subject: Gentlemen: Short Summary: The State of Alaska, A.O.G.C.C. April 30, 1998 Matt Scheuring Doyon 14 Operations Drilling Engineer 13-02B Operations Summary: The liner on well 13-02B has been set approximately 800-900' high. (See attached diagram) Detailed Explanation: On the evening of April 29, 1998, Doyon Rig 14 was running a slotted production liner on Drill Site 13, when deeper progress was not possible due to hole drag which stuck the liner at a measured depth of 13,148' MD, between 800'-900' short of TD. The slotted production liner was not planned to be cemented.

The well had been 'Shutdown of Well Operations' on 03/17/98 due a contractual agreement that Doyon rig 141 would leave PBU field to drill at the Alpine field. Prior to rig 141 leaving for Alpine, a cement plug was set in the sidetracked wellbore 25' below the 7" casing window at + 9,200' MD. 3,000' of 4 1/2" tubing was hung below a tubing hanger and a dry hole cap was installed on top of the well prior to shutdown. When Doyon rig 14 arrived, the 4 1/2" tubing was pulled and a directional drilling assembly RIH to re-enter the sidetrack and drill off the cement plug through the Kingak formation to the original Sag River target. After drilling 130' of the Kingak the shale packed off (as it had 375' into the original sidetrack wellbore). The pipe was worked free, but it was decided to move up hole + 150', set another whipstock, mill a new window, displace the well to 11 ppg, Oil Base Mud, and drill a new wellbore to the original Sag River target. After drilling 324' of new 6" hole out of the new window (45° to 80° inclination) the Kingak shale once again packed off the drill string. The pipe was worked free but could not drill back to bottom (TD + 9,362' MD, window at + 9,038'). A 6" fixed blade hole opener with rotating assembly was RIH but, it too, could not open the hole back to bottom. A 20 bbl, 15.8 ppg, Class 'G' cement plug was set in the open 7" casing from 9,026' to 8,500'. The plan ahead is to safely displace the oil base mud out of the hole. Set an EZSV plug + 3,450', set a 9 5/8" Whipstock on top of the EZSV, mill a new window through the casing into the SV3 formation, directionally drill to the original target in the Sag River. The plan is to drill the Kingak at 40° inclination rather than 85° (we have learned that the Kingak Shale is mechanically unstable under DS 13). Set 7" liner in TSAG, short radius drill to the original target polygon of the Sag River formation to TD. Run and test 4 1/2" slotted liner and complete well with 4 1/2" tubing, (3) GLM's and EOA tail assy. Revision to the ©riqinal Well Plan 1. Carefully and safely displace Oil Base Mud to Seawater. POOH. 2. Change rams, Test BOPE 3. RU e-line set EZSV + 3,450' (7" scab liner top at 3,460'). Follow Whipstock Sidetracks RP. Note' Will need Gyro Data to orient Whipstock and tool face. Shut in well and test casing to 3,000 psi for 30 minutes against the Bridgeplug to insure casing integrity. If casing leaks PU a RTTS for 7", 29# and identify the leak depth (notify ODE). 4. MU 8 ¥2" GT-LG1XL bit with Sperry Sun MWD assembly (no GR), RIH, drill ahead to bit exhaustion. Note: This bit should drill this upper section 70' - 120'/hr. 5. MU Hycalog DS 70 PDC, MWD/GR drill to 10' into Sag River. Circ and clean hole for csg. POOH SLM. Note: Will be crossing a 30-50' throw fault @ 600' before TSAG. Need to PU GR to help find Sag River. 6. Run and cement 7", 26#, L-80 liner. Space the liner hanger/packer at 1,000' MD inside the 9 5/8" csg ( there is a weak spot in the 9 5/8" csg at _+ 1,250'). Cement the liner in place with the total lead cement volume based on 50 % excess in the openhole, plus 80' shoe joint. Displace at 8-10 bbl/min. Put cement top 1000' above the 7" shoe. 7. MU 6" STR 09D bit, MWD/GR BHA and PU 4,000' 3 1/2" DP. Clean out to 7" float collar and test casing to 3000 psi for 30 mins. Perform a well kill drill prior to drill out. Drill 20' of new hole and run a formation integrity at 0.5 ppg or more than expected mud weight to be used to drill the section. Displace to 8.7 ppg Quikdriln mud system. Drill ahead as per directional plan to TD. Circ and clean hole to run slotted liner. 8. RIH with 4 ~/2", L-80, 12.6# slotted liner. Set hgr/pkr + 150' above the 7" shoe. Drop neutral weight ball, set pkr. Test packer on annulus 3500 psi for 30 mins. Release from packer, pressure up and shear out seat. Circ until clean seawater. POOH lay down DP. 9. RIH with 4 1/2" L~80 completion with SSSV, 3 GLM's and 7" production packer with standard EOA tailpipe assy. Circulate corrosion treated seawater into the annulus. Set packer and test tubing to 4000 psi for 30 minutes. Bleed off tubing pressure to 2000 psi after test, pressure up annulus to 3500 psi for 30 minute test. Follow RP for Running Tubing 10. Set BPV and test. ND BOPE. NU tubing head adapter and tree. Test tree to 5000 psi.. Pull BPV. Freeze protect through shear valve in top GLM. Set BPV and test. 11. Release rig to K pad.

The well had been 'Shutdown of Well Operations' on 03/17/98 due a contractual agreement that Doyen dg 141 would leave PBU field to ddll at the Alpine field. Prior to rig 141 leaving for Alpine, a cement plug was set in the sidetracked wellbore 25' below the 7" casing window at +. 9,200' MD. 3,000' of 4 1/a" tubing was hung below a tubing hanger and a dry hole cap was installed on top of the welt prior to shutdown. When Doyen rig 14 arrived, the 4 1/2" tubing was pulled and a directional ddiling assembly RIH to re-enter the sidetrack and drill off the cement plug through the Kingak formation to the original Sag River target. After ddlling 130' of the Kingak the shale packed off (as it had 375' into the original sidetrack wellbore). The pipe was worked free, but it was decided to move up hole +_ 150', set another whipstock, mill a new window, displace the well to 11 ppg, Oil Base Mud, and drill a new wellbore to the original Sag River target, After drilling 324' of new 6' hole out of the new window (48° to 80= inclination) the Kingak shale once again packed off the drill string. The pipe was worked free but could not drill back to bottom (TD _ 9,362' MD, window at ;I; 9,038'). A 6" fixed blade hole opener with rotating assembly was RIH but, it too, could not open the hole back to bottom. A 20 bbl, 15.8 ppg, Class 'G' cement plug was set in the open 7" c~sing from 9,026' to 8;500'. The plan ahead is to safely displace the oil base mud out of the hole.

As we discussed over the phone yesterday, this e-mail is to inform you that on the above captioned well we will be changing the drilling fluid from the standard 8.9 ppg Flopro fluid to 8.5 ppg seawater. The reasons for this change is that a BHP measured inthis well on 2/28/99 showed a BHP of 1500 psi which is considerably less than the original presure of 3200 psi. This pressure yields a gradient of 3.3 ppg @ 8800' ss. Also in killing this well prior to running the whipstock assembly, the well would not hold a fluid column to the surface. We anticipate that we will drill the wel with fluid losses and therefore will continually pump down the CTx tubing annulus throughout the drilling and completion operation. If you have any questions, please call me at 265-1305 or e-mail me.

A 6" hole was then directionally drilled with 10.5 ppg 6% KCL Gel Free Shale Inhibited Mud in the Kingak Shale to a depth of 9,965' at 90° horizontal where the pipe got stuck while making a connection. The pipe was jarred and worked up hole to a depth of 9,836' where the pipe packed off completely. An e-line string shot was RIH and the drill pipe was backed-off at 9,619' MD. The fish left in the hole consisted of one (1) it. of 3 1/2" DP, (1) PBL circulating sub, (1) drilling jar (up and down), (3) 4 3A" flex drill collars, Sperry Sun MWD, (1) short flex DC and float sub, 1.75° shod pack drilling motor and 6" bit. A screw-in fishing assembly was RIH and successfully engaged the fish. The fish could not be retrieved after eleven hours of jarring and working the fishing assembly. It was decided to set a cement plug on top of the fish and up to the milled window, then abandon this section of the hole. After the cement plug is set in place the well will be Shutdown of Well Operations leaving the original sidetracked wellbore cemented, a 4 1/2" hanger with 3000' of 4 W', L-80 tubing hung in the existing wellbore and the rig will be released to move to the ARCO Alpine field. Doyon Rig 14 is expected to resume operations on the well as soon as February 16, 1998 but no later than May 15, 1998. Objective: Unscrew out of the fish at 9,619' and POOH with the fishing assembly. RIH with a cement stinger on 3 1/2" DP, tag the top of the fish and pick-up 2-3'. Pump a one stage drill-off cement plug from + 9,619 to 9,200' MD (25' below the casing window). Reverse circulate excess cement, POOH laying down DP. Prepare well for shutdown of operations and release rig to ARCO. Revision 1. Back out the fishing assembly from the fish at 9,619'.

Mud Program: Special design considerations The final mud used on well 13-06A will be stored and re- conditioned to be used to drill the short 6" Kingak interval on this 13-02B well. Calcium carbonate bridging material will be removed and re-weighted with barite. Some additional Barotrol and Baranex will need to be added but the salvaged mud does contain shale inhibition products.

If Cl I wastes are generated, they will be taken to the Pad 3 disposal site. Drilling Discussion Well Objective 13-02B is a horizontal sidetrack targeting the Sag River Sandstone. This well is in the gravity drainage area in northern DS 13 near the Sag gas cap. Favorable results from 12-13B Sag pilot well and the large undeveloped area of the Sag reservoir north of 13-02A promote dedicated Sag offtake in this region. This well is part of the "opportunity exploitation" of the Sag reserves near the gas cap which utilizes existing assets with marginal Sadlerochit targets. An estimated 10 mmstbo of EOA Sag recovery is at risk in this "gas cap drive" area if it remains undeveloped. This well drains an area of 160 acres below the gas cap with expected 6 month average production rate of 1,300 bopd. Because of the low permeability of the Sag River this well is expected to produce at 1,000 bopd for years. Drilling Objective The objective is to cut and pull the existing 5 ½" x 4 ½" x 3 ½" completion tubing above the 7 x 3 ½" production pkr @ 9,490' MD, mill a window by whipstock in the 7" scab liner @ 9,200' MD, directionally drill 6" hole _+ 250' into the Sag River formation @ 10,273' MD. Run, cement and test a _+ 1,350', 4 ½" liner. Drill out the shoe with a 3 ~" PDC bit and directionally drill Sag River horizontal to TD at +_ 14,570'. The well will be completed as a Sag River producer with a 2 7/8" slotted liner set in the Sag horizontal section and hung in the 4 ½" liner. The 4 1/2" liner will have a MLAS joint in the string at the Sag River formation top (for a future CT Sag River well to the east). A 4 ½" tbg. completion crossed-over to 5 ½" (to fit the hanger) with (3) GLM's will be run. The 7" x 4 ½" production pkr. will be set at _+ 8,988'. The well will be directionally drilled out of the 7" window to TD where none of the build or turn angles will exceed 12°/100'. The soft dog legs will minimize drag in the extended wellbore. DRILLING HAZARDS AND CONTINGENCIES Always have two levels of tested isolation before NU/ND. SURFACE CLOSE APPROACH WELL SHUT-INS There are no wells which need to be shut in during the rig move. Surface well spacing of the adjacent wells is 120'. Careful coordination with any ongoing pad or facility operations or activities will be initiated prior to commencing the rig move. DRII,LING CLOSE APPROA~4 WELL SHUT-INS No shut-ins identified on Sperry Sun directional well plans. Wells 13-03, 13-20, and 12-19 failed the PBU anticollision guidelines and will require exemption from 9,200' to 11,930' MD. The closest actual point to point separation falls within the area where proximity is still 'passing', but the proposal fails proximity from 9,300' to 11,930' MD. Presently, Well 13-03 is shut-in at surface, Wells 13-20 and 12-19 are water injectors. ~ DS 13 has had H_2S reported: The highest levels of H2S from currently producing wells is 122 ppm from 13-05 measured on 10-17-95. Four other wells on DS 13 have reported H2S of _< 36 ppm. H2S precautions will be in effect at all times. These include (but are not limited to): · Regular H2S drills (minimum of two per week) · Proper training of all permanent onsite personnel, unescorted visitors and temporary onsite personnel · H~S monitors with both audible and visual alarms · Access to 5-minute emergency escape air packs · Personal H2S monitors · Functional wind indicator · Posted evacuation routes (minimum of two) · Muster points in designated safe areas; H__~_S · Functional communications between rig camp and rig floor. Surface Casing Shoe Kick Tolerance The smallest kick tolerance for the kick off window is calculated as infinite of influx assuming a swabbed gas influx at the top of the Sag River along the planned directional path. Based on 8.7 ppg MW (Sag at 10,682' MD & 8,841' TVD 7.0 ppg reservoir pore pressure), and frac at the window 12.0 ppg. Pre-Rig Work 1. RU slickline and drift 3 V2" tbg.
