Neil Magee - BPXA GPB Rotary Drilling Subject: Reference: W-23 Application for Sundry Approval - Isolation for Sidetrack Operations APl # 50-029-21993-00 Approval is requested for the proposed well work of PBU well W-23 in preparation for a sidetrack (W-23A) of this well bore. Well W-23 was drilled and completed in January 1990. The well was completed with a series of sliding sleeves and CTC packers across the open hole interval, f The well initially produced 500 BOPD at 80% WC. A cement squeeze was performed on the well in March 1990 to isolate the lower 42P interval which was suspected of being the source of the produced water. The cement squeeze clogged up the open sliding sleeves above and the well was perforated through the tubing interval to restqre~"~ctivity in March and April of the same year. After a period of one year, production had fallen to~00' B~ Subsequent HCL stimulations were able to stabilize the well at approximately 600 BOPD. A ~~'performed on the well in 1997 with no increase in oil r..~tes. The production rate subsequently fell to 250 BOPD. The well is currently sanded back to 9900' and shut in due to well integrity issues. Currently the well appears to have a fish or perhaps collapsed tubing at 6976' and numerous holes in the completion tubing above the packer. (A video surveillance.r4:n'r was run to verify the tubing condition and to try and identify the fish.) Coil tubing operations are planned in late March to clean out the fish/ascertain if the tubing is collapsed. Based upon the poor tubing condition and added drainage by drilling a lateral through the existing completion interval (46P through 43P), the decision was made to pursue a sidetrack using a rotary rig. ~' The W-23A sidetrack is currently scheduled for Nabors Rig 0ES, beginning around 03. The pre-rig work for this sidetrack is planned to begin as soon as the attached Application'f~F~Sundry is approved. Proposal We would like to propose relief from the usual requirement for cement isolation in the current wellbore ahead of sidetracking due to the following: · The lower portion of the original well, 42P sand and below, was squeeze cemented in 1990 to provide isolation from the original open hole below and to eliminate the potential water encroachment. · The sidetracked well-will-'bew~mpleted with a slotted liner across the same zones as the parent well and in v~'close~' y. . · The prospect-~E;FalltTcult cleanout to current well TD in light of a tubing fish and sand placement from TD to 9900'. ·The limited benefit of performing a cement squeeze in the current completion due to the questionable isolation provided by the CTC packers in the original completion. · The risks associated with squeeze cement interfering with subsequent tubing cuts due to the known and unknown holes in the current completion tubing.

I've attached a current and planned schematic of the well as well as a geologic cross section for your review. Discussion: The sidetrack well will be completed with a slotted liner cross cuffing the Zone 4B (46,45,44 and 43 sands). The well will be kicked off with 20 degree doglegs just below the Sag river landing _in the 44 sand inverting at the 46 sand and TD'ing in the 43 or 42 sand depending on the OWC. The slotted liner completion will cover all sands currently open in the original completion with the exception of the 42 sand. The top sand will be cut when the sidetracked well is some 40' away from the parent well and the lower 43/42 sand will be cut when the sidetracked well is approximately 1200' from the parent well. From a reservoir cross flow perspective, further isolation of the original wellbore is not a requirement. The original completion was squeezed below 10,020' to shut off potential water encroachment from the open hole completion below. The completion was sanded back to 9900' as part of an unsuccessful frec job performed in 1997. The well is able to produce from the top perforation interval at 9850-9890'. There is an unknown fish in the tubing at 6976', which will have to be milled out or pushed to bottom ahead of the tubing cuts required to de-complete the well. This fish may prove problematic to remove and if we are successful in pushing the obstruction down to the top of sand at 9900', may prevent further clean out progress. The pre-rig entails a tubing cut at 9750' to allow for setting a whipstock. Well Status: The well is currently shut in. The wellhead was reported to be leaking at two small areas between the lower wellhead housing and the 13-3/8" casing. Well Integrity Engineers have been asked to inspect wellhead and make appropriate welding repairs prior to the rig mobilization. A video surveillance was run on the well 12/10/03 to determine the nature of the obstruction in the tubing at approximately 6976' (SLM). The obstruction appears to be metal debris laying over in the tubing at that depth. A bailer run was run without recovery. Tubing leaks have been identified at 6892', 6937', 6939', 6985', 6999' and 9448'. The pre-rig entails verifying the wellhead/13-3/8" casing leak has been corrected, in conjunction with safe out of the well for wellhead repair, performing a clean out run with coil, testing the wellhead pack-offs and performing tubing cuts. proposal We would like to propose relief from the usual requirement for cement isolation in the current wellbore ahead of sidetracking due to the following: · The lower portion of the original well, 42P sand and below, was squeeze cemented in 1990 to provide isolation from the original open hole below and to eliminate the potential water encroachment. · The sidetracked well Wi~i'~e completed with a slotted liner across the same zones as the parent well and in very close proximity. The prospect of a difficult cleanout to current well TD in light of a tubing fish and sand placement from TD to 9900'. · The limited benefit of performing a cement squeeze in the current completion due to the questionable isolation provided by the CTC packers in the original completion. · The risks associated with squeeze cement interfering with subsequent tubing cuts due to the known and unknown holes in the current completion tubing. I'm available to discuss this with you at your convenience and will contact you prior to any proposed pre-rig work ahead of the W-23a sidetrack.

The well is completed with a series of sliding sleeves and CTC packers and came on at 500 BOPD and 80% water. A cement squeeze WSO of the well in 3/90 clogged up all the sliding sleeves. Perforations through the sliding sleeves were added after the cement squeeze to restore productivity to 500 BOPD at lower watercut. W-23 quickly declined to 100 BOPD and an HCL stim of the perfs in 1/91 increased production to 1000 BOPD. A second HCL treatment in early 1992, kept the well producing at 600 BOPD. A frac in 1997, screened out and did nothing to improve oil rates. Since 1999, W-23 has declined to 250 BOPD. With the frac'd sliding sleeve completion, there are no further wellwork options to stimulate this well. Currently, W-23 is sanded back to 9900' MD and is shut-in due to integrity issues.- W-23 Integrity issues as follows: 07/12/97: Hole in tubing @ 9448' Pup joint at GLM #1.

The present oil-water contact (POWC) is inferred from well water cuts with the addition of one good recent control point to the east in well W-21A. There is a Iow chance of having some gas under-runs (UR) below TSad and the 45N Shale. We have three estimates of the Gross Light Oil Column based on three potential fluid scenarios. Low Case -8825 Expected Case -8825 High Case -8825 86' 115' The expected case (Figure 2) honors the existing log data and assumes a tabular rise in water with no coning of water near existing production. It is a somewhat conservative estimate, as recent drilling has indicated that the influx water level is highest near existing production The Low Case is similar to the expected case but has subtracted 10' from the Gross light Oil column for possible gas under-runs. The Hiqh Case assumes that the POWC approaches original levels away from existing offtake and that the well data represent coning of water near the well bore. Structure: The proposed W-23A well is located north-northwest of W Pad in the Main Fault Block shown on the attached Top Sadlerochit structure map (Fig. 1) and seismic continuity map (Fig. 4).

The target polygon is shown in yellow and red lines (hard-lines) Faulting: Overall the lost cimulation risk is considered Iow (20-40% chance for some losses). While both the W-21A and W-32A wells had significant losses, the majority of these losses are interpreted to be associated with fault crossings. No fault crossings are expected in the W- 23A well. Them is one region near the heel of the well that may be a southern extension of a small fault, but there is no seismic evidence for this fault, apart from a small change in the stratigmphic dip.

The northern side of the target polygon is a hard-line to maintain standoff from a small 5' fault, to the north. The southeastern side of the target polygon is a hard-line to maintain 400 ft. standoff from perforations in W-21A. As shown in Fig. 4, no major faults are mapped between W-23A and W-24i. Significant impact on sweep efficiency is not expected.

Seismic Quality Seismic quality (Hurl-West end survey) is moderate to good (Fig. 5). The seismic velocity gradients, while generally smooth, do not have a large amount of well control to the Northeast. The W-23A well is located in an area of changing velocity (Fig 6), and will be going from a zone of lower to higher velocity. Formation depths are expected to be close to estimation near the kickoff point. However, due to uncertainty in the velocity gradient, depths are estimated to be within +/-30 feet of prognosis away from the two existing control points (W-23 and W-21A).

Currently the parent well is shut-in due to tubing collapse. The parent well has a small remaining value that requires a tubing change-out to be realized. This is an alternative case to sidetracking the well. The relevant drainage patterns and MI sectors are shown in Figure 7. The target length of the lateral is 1330 feet with an 900 foot effective reservoir section. It is assumed that 400 feet will be non- contributing (shales, high Sw, or blanked off faults). W-23A is one of four production wells in the W-24i MI injection pattern (Figure 7); the other wells are W-18, W-22 and W-32A. The heel of W-21A may also receive some benefit from W-24i. Volumetric estimates are summarized in Table 1. For primary recovery, W-23A will drain 226 acres containing 8.444 MMSTB OIIP. Presently, 24% of OIIP in this drainage area has been produced (2.00 MMSTB) by W-23. Drilling the proposed W-23A-is- expected to raise primary recovery to 37%, yielding 1.129 MMBO SLP. Table 1.

'The MI benefit is estimated at 10% of this OOIP, or 0.278 MMBO. The parent W-23 MI recovery (if the well is repaired instead of drilling a sidetrack) is estimated at 0.119 MMSTB (10% of an OOIP of 1.189 MMBO). MI injection starts 1Q04. The MI slug is estimated to last about one year (350-400 days effective injection time at 12-15 MMSCFPD). The MI injection period is based on a slug size of 40% of the HCPV in the target MI zones. The MI slug is followed by water injection to displace and sweep out the mobilized oil before additional slugs of MI are applied. Currently the parent well is shut-in because of its mechanical condition. An alternative to sidetracking the well would be to repair the well (tubing change-out). Decline curve analysis indicates that the parent well would recover an additional 0.508 MMBO SLP if we can restore production levels to those before the tubing collapse. With MI benefits, the total IOR reserves for fixing the parent well are 0.572 MMBO. A conservative cost estimate for a tubing change-out is $1.2 MM, yielding $2.10/BO. As seen in Table 2, S:\GPB\Well Files\W~W-23A\Planning\W-23A Tech Package\W-23A Rig Technical package.doc 20-M~r-03 Page 13 of 20 repairing the well is not competitive with sidetracking the well. Hence, for the purpose of this analysis, it is assumed that the parent well remains shut-in. The sidetrack trajectory attempts to minimize loss of parent well reserves. 1311 Figure 7.

THE HALLIBURTON 3.5" RCP PACKER/PATCH IS RETRIEVABLE. THIS WAS SET FROM THE TOP SEAL AT 9433.5' TO 9451' PROVIDING 17 FEET OF COVERAGE. THE HOLE WAS LOCATED AT 9448'.

GLM # 1 @ 9440' and tbg leak @ 9448' should be totally isolated. Top of tbg patch assembly @ 9431.75'. Min ID thru patch = 1.31". Total length of patch - 22.37'. '1" Fluids Pumped BBLS. Description FRAC Operation 11/13/97 A Hydraulic Fracture treatment was performed using the following fluids:: SUMMARY The job was pumped without problems. There was not much reaction to acid treatment and subsequent soak sequence. There was still significant near well bore friction observed through out job, although treating pressures were lower than previous frac attempt. Well screened out while'in flush stage with 3 ppg on perfs. Got 4,500 lbs of 20/40 carbolite behind pipe and leaving 16,305 lbs in liner and tubing. Estimated sand top at 1724'. Recommend attempting to pull fit before cleaning out with coil.There were several changes to the program to note: First, the acid was change from 15% Hcl to 12% 90:10 Dad based on recent stim results out a W-Pad. Second, there was discrepancy in the frac design where 60' and 70' frac height had been used in the frac and data frac design. The 1st data frac was recalculated using the 60' parameter. Third, there was difficulty concluding fluid efficiency from the 1st data frac and so a the 2nd was pumped. Last, the frac design had changed significantly, such as increased pad volume and reduced total sand volume, based on all the previous data. ! Fluids Pumped BBLS.

The Drilling fluid program will consist of an 8.5-9.5 ppg spud mud in the 17- 1/2" hole, a 9.0 - 9.7 ppg water base mud in the 12-1/4" hole and a 9.5 ppg water base mud in the 8-1/2" hole. Directionally drill 17-1/2" hole (a surface nudge is required to avoid well W-24) to 2700' MD and cement 13-3/8" L-80 Buttress casing to surface. Install blowout prevention equipment consisting of 5000 psi W.P. pipe rams, blind rams, and annular preventer. Maximum possible bottomhole pressure is 4390 psi at 8800' TVDss based on original reservoir pressure. Maximum possible surface pressure is 3330 psi based on a gas column to surface from 8600' TVDss and an oil column to 8800' TVDss. Directionally drill 12-1/4" hole to the 9-5/8" casing point 60' below the top of the Shublik formation. Run 9-5/8" 47# NT-80S NSCC casing to within 5' of 12- 1/4" TD and cement using Class G cement around the 9-5/8" shoe. Drill 8-1/2" hole to TD. Run open hole logs and if appropriate run tailpipe tubing completion, incorporating external casing packers and sliding sleeves for slective zone isolation and production. A 9-5/8" production packer will be run on the 3.5" tubing. A subsurface safety valve with dual control lines will be placed 200' below base of permafrost. Install and test Xmas tree. Release Rig. Rig up Coiled Tubing Unit and inflate the external casing packers with cement. Reverse out cement to PBTD. Rig down the CTU and bring the well on production by opening the sliding sleeves with a slick line unit. If the open hole logs or hole conditions dictate running a liner, a 5 1/2" liner will be run from TD to 250' inside 9-5/8" casing shoe and cemented using Class G cement. Clean out to 5 1/2" float equipment. Change over to 8.9 ppg. filtered NaC1 completion fluid. Test casing and lap to 3000 psi. Run CET/CBT/CCL-GR and GYRO. Perforate with wireline conveyed guns. Fluids incidental to the drilling of a well will be pumped down the 9-5/8" x 13-3/8" annulus of the well. Tubing Size: 3-1/2", 9.2# L-80 TDS TBG with GLM's.
