Home My WebLink About196-069Memorandum State of Alaska Oil and Gas Conservation Commission To: Well File: Prudhoe Bay Unit 15-45 Permit # 196-069 August 15,2001 Re: Administrative Abandonment Action Prudhoe Bay Unit 15-45 Permit # 196-069 This memo will remain at the front of the subject well file. Well 15-45 was replaced by 15-45A (permit # 200-068, API# 50-029-22671-01) when the permit was approved 5/18/2000. The replacement well incorporates an extension to a new bottom hole location using the existing well bore. This extension, along with the original hole, will be used for production of hydrocarbons. A review of both well files indicates administrative abandonment of the originating well bore is appropriate according to current AOGCC procedures for wells where additional permitted extension is drilled from an existing well bore. 20 AAC 25.005(a) requires a Permit to Drill for each hole drilled below the conductor unless drilled to straighten the original hole, sidetrack junk, or correct mechanical difficulties. In addition, AOGCC data bases require each conductor has only one permit number and API number. Administrative abandonment of the original permit only eliminates duplication in the databases. Information for the original well and its replacement will be maintained in their respective files. The operator has been notified of this action. All future correspondence with the AOGCC should reflect the new permit number, API number and well data.

Commission, 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 10g. · 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-01, L-16, J-19, L-25, F-30, .L-21, K-38, NMP #1 & K-05, K-02,1t-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 mason 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.

This annulus had been used to inject rig water waste while the well was being drilled after the 7"casing had been set and after injecting approximately 1800 bbls. returns to surface appeared in the cellar. The well had been completed and the dg was move off. ! arrived at the location and met with Vance and he gave me the details of the cement job. B & J Cementing Services moved in and rigged up. They pumped 110 bbls. of fresh water down the well at a rate of 4.5 bbls/min. @ 800 psig. Then 51 bbls. (300 sks.) of 14.9 lb/gal. Cold Set 2 was pumped at a rate of 4.5 bbl/min. @ 900 psig which dropped to 300 psig at the end of the cementing. Then 21 bbis. of fresh water was pumped followed by 57 bbls of diesel to freeze protect with a final pressure of 1500 psig at 4.5 bbls/min, with the amount of cement pumped plus the 21bb/s. of fresh water and 57 bbls. of diesel the CTOC should be 1000' above and below the 9.625" casing shoe. Cement was in place at 00:30 AM and 750 psig left on the casing. ! monitored the cellars on 15-45 and the adjacent well and observed no influx in done of the cellers. Sunday, May 5, 1996: i returned to the location at 8:00 PM this date and a pressure test was performed. The casing was 0 psig at the start of the test and was pressured to 1500 psig and held for 20 minutes with no pressure loss. I told Vance that everything looked OK to me and the well was turned over to production. Summary: I witnessed the placement and testing of the cement set in the 9.625" X 7" andnuaus on ARCO PBU well DS 15-45.

AOGCC requests a field inspector to witness this work, contact 24hrs prior to the job. OBJECTIVE: Establish pressure integrity and seal in the 9-5/8" X 7" annulus and isolate the 9-5/8" casing from the Cretaceous formations. This objective will be achieved by down squeezing COLD SET II cement below the 9-5/8" casing shoe and leaving 500' of cement in the 9-5/8" X 7" annulus just above the 9-5/8" shoe. Rig up BJ lines to the 9-5/8" X 7" casing annulus. Pressure test lines to 3000 psi. Open the annulus valve on the wellhead and establish injection rate with water. Build up rate in steps to achieve 5 BPM but do not exceed 3000 psi injection pressure. Injection pressure is expected to be near 1300 psi at 5 bpm with water based upon prior injection of mud. Pump a total of 110 bbl of water ahead (annulus capacity is 108bbl) Mix and pump 37 bbl (220 sx) of Cold Set II cement at 14.95ppg, 0.961 ft3/sx, to provide 1000' of cement in the open hole X 7" casing and 500' of cement in the 9-5/8" X 7" annulus above the 9-5/8" casing shoe. Displace the cement slurry with 25 bbl of water followed by 69 bbl of diesel to place the TOC at 3329'MD (500' above the 9-5/8" casing shoe) and to freeze protect the upper annulus. Maintain injection rate and monitor squeeze pressure, especially when cement reaches the 9-5/8" casing shoe at about 71 barrels into displacement. Stop pumping, close annulus valve and rig down BJ. Monitor annulus pressure. 24 hours after cement is in place, pressure test the 9-5/8" X 7" annulus to 1000 psi or final squeeze pressure which ever is greater.

Arco PBU OS 1 5-45 Prudhoe Oil Pool PTD # 96-0069 Thursday, April 25, 1996: I traveled to Arco's PBU 0515-45 well to investigate the flow of fluid to surface from around the 9 5/8" casing into the cellar. I inspected Doyon 14 cellar area I did not see any visible fluid flow, however the 48" cellar was full of fluid. The adjacent cellars show no signs of fluid flow in or around them. I met with Shared Services rep. Gene Cooper and discussed the situation with him. Gene had only been on location for 1 day and was totally in the dark about the history of the well. Gene assured me that warning signs, prohibiting annular injection, would be made up and place on the well head after completion. Gene copied the morning drilling report covering days April 18 thru April 20, 1996, the time span in which the 7" production casing was run and cemented. The copies were of poor quality therefore I transcribed the important facts pertaining to the 7" casing job, this copy is attached for reference. From the information I gathered I do not understand why annular injection was permitted in this well in the first place.

I had conversation with a Shared Services representative concerning the lack of cement returns to surface on the 9 5/8" casing.

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. 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 contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. DavidChairmanW.

Drilling Supt. 564-5026 564-5219 345-8660 346-2026 275-4015 275-4539 Drilling Hazards Surface Hole Possible tight hole in both the permafrost and lower zone, hole enlargement and casing drag. Hole cleaning is critical, design flowrates high enough to clean the expected washed out hole, not gauge hole. It is recommended that all drills, except for a diverter drill, be scheduled for either casing point or lower section of hole. Drill, case and cement the surface hole as fast as possible. Faulting In many wells on Drill Site 15, drilling through faults has resulted in catastrophic lost returns. Be aware that faults are present on Drill Site 15 and are known to be conductive. The asset have listed as a major uncertainty the presence and location of smaller conductive faults. A fault with up to 50' of throw is possible just above the Sag River (Sag top at 9174'MD, 8209'TVD). No other faults have been prognosed within the target polygon. Close Approaches The nearest surface well, 15-33 is 30ft south from the 15-45 wellhead. The 15-19 well is located 30ft north of the 15-45. Both wells will be shut- in and secured during the move in and rigup/rig down. The wells can be returned to service after rig up and until just before rig release. There are no deep close approaches. Pore Pressure Expectations CRETACEOUS (3832'-7061'MD): The Cretaceous interval on Drill Site 15 has possible overpressured sands in the T-5 to K12 intervals. The degree of overpressuring will depend at any given time on the daily injection volume at GC3-D. The 15-48, drilling on Jan 23, 1996, had flow between 4000-5675 MD, (4000-5630 TVD). Mud weight had to be raised from 9.3 ppg to 9.8 ppg. Close contact with the onsite pad supervisor on the injection status at GC3-D is necessary. It is recommended that a 9.8 ppg mud is in the hole prior to 4500 TVD. K-5 to BASE HRZ (8245'-8863'MD): Pore pressures should be in the normal range considering shales (9.2-9.5 ppg) but 9.8 ppg should be maintained due to Cretaceous overpressure. PUT RIVER (8874'-8921'MD):(45'TVD thick) Some gas cut mud problems have been observed. It is recommended that mud weight be 10.4 ppg at the Put River. 15-48 drilled into the Put River with 10.0 ppg mud, the mud was gas cut and the weight was raised in steps to 10.4 ppg before drilling ahead while prior wells this year and late last year on DS 15 drilled the Put River with 10.0-10.1 ppg. The 10.4 ppg weight should produce sufficient overbalance for the Put River. High levels of cuttings gas should be expected from this interval. If gas-cut mud becomes a problem, pick up off bottom and circulate the gas cut mud out of the system. If after circulating bottoms up the gas still appears in the mud, raise the mud weight by 0.1-0.2 ppg and circulate the gas out. Continue drilling if the well appears stable. SAG RIVER (9174'-9225'MD): No DS 15 well drilled during the 1995-96 season has seen problems with the Sag while drilling with 9.0-10.4 ppg fluid. SADLEROCHIT (9289'-TD): Current pore pressure in the Sadelrochit is 3550 psi @ 8800' TVDss (7.7 ppg EMW). Mud weights used on DS 15 previously were 8.8 - 9.3 ppg. Lost Circulation Lost circulation has been a serious problem on Drill Site 15, but catastrophic losses have been primarily associated with crossing faults. Be prepared to handle massive lost circulation associated with faults following M-I's recommendations, a prototype (Damaging) massive loss circulation prevention fluid has been developed but not tested, use is decided on a case by case condition. Check with D. Nims before use. Lost circulation from seepage has been most common at mud weights greater than 10.2 ppg, with loss rates of 20 - 50 bph. Be prepared to handle lost circulation as we drill below the Put River. If lost circulation due to seepage occurs and is at a Iow rate, OM Seal and Liquid Casing have shown to be effective. In cases of catastrophic losses, pre-treatment with calcium carbonate followed by Maraseal has been effective in controlling losses. · Stuck Pipe There has been several cases of stuck pipe, 15-6 Cretaceous, 15-24 Ivishak and 15-4 Ivishak zone 2. There were also some cases of tite hole. Stuck pipe potential for this well is highest in the Sag River and Shublik due to the decrease in pore pressure, and in the Kingak due to mud weights too Iow for the stabilization of the shales · Surface Casing Shoe Kick Tolerance The smallest kick tolerance for the casing shoes is calculated as 29.3 bbls of influx assuming a swabbed gas influx at the top of the Put River along the planned directional path. Based on 10.2 ppg MW (8874'MD & 7927"TVD, 10.2 ppg reservoir pore pressure, and a 12.5 ppg shoe test. 15-45 DRILLING AND COMPLETION PROGRAM , MIRU drilling rig. N/U diverter and function test same.

All drilling and completion fluids can be annular injected. Well DS 15-45 is being permitted for annular injection. Request to AOGCC for Annular Pumping Approval For DS 15-45 1. Approval is requested for Annular Pumping for well DS 15-45 and any well on the pad/drillsite previously permitted for disposal activities by AGOCC. 2. The Base of the Permafrost for all wells located in the PBU Unit is 1900 feet. Aquifers in the PBU Unit have been exempted from Class II injection activities by the AOGCC by Aquifer Exemption Order #1 as referenced in Area Injection Order #4 (PBU-EOA). 3. The receiving zone to which the fluids will migrate is identified as the Sagavanirtok (Tertiary/Cretaceous Sands) geological formation at 3579 'TVD. The confining layer is the overlying shales above the SV3, defined by the base of the permafrost and 3574 'TVD. Additional data which demonstrates the confining layers, porosity, and permeability of the injection zone was submitted to the AOGCC on 7/25/95. 4. There are 54 wells on Pad/Drillsite 15. There may be additional unidentified wells within a quarter mile distance from the subject well. There are no domestic or industrial water use wells located within one mile of the project area. 5-6. The drilling wastes to be disposed of during this operations can be defined as drilling muds and cuttings, rig wash up and waste water, cement wash up water, brine, and formation fluids. The maximum volume to be disposed of in the annulus is 35,000 bbls. The maximum density is 17 ppg. 7. The Maximum Allowable Surface Pressure while annular pumping is calculated according to the following equation and is 1523 psi for a 17 ppg fluid in this well. MASP = 4325 psig - ((fluid density ppg - 1.9) X 0.052 X 9-5/8" Casing Shoe TVD 8. The 9-5/8" casing shoe will be set at 3820'md (3569' tvd) and cemented with 1547 sacks of cement. This depth is below the base of the permafrost (1900'TVD) and into the SV3 formation which has a long established history of annular pumping at PBU. 9. The burst rating (80%) for the 9-5/8" casing is 5496 psig while the collapse rating (80%) of the 7" 26# L80 casing is 4325 psig. The break down pressure of the Ugnu formation is 13.5 ppg equivalent mud weight. 1 0. Pumping into the hydrocarbon reservior will not occur. DO NOT EXCEED 35,000 BBLS IN ANY ANNULUS.
