L-205 has major damage at the L5 junction and has produced sand and rocks, rendering it unfit for production. There is currently an obstruction at the L5 junction restricting access below. All remaining options to re-access the L- 205 laterals have been exhausted. Due to the history of solids production and the inability to clean the wellbore, it has been released for sidetrack. (o4 ,115M(/7y�� Scope of Work: Prior to rig arrival, a bridge plug will be set in the 4-1/2" scab liner and 25' of dump bail cement will be placed on top of the plug. Top of cement will be tagged and wellbore integrity will be verified. The tubing will then be cut above the production packer. The rig will pull the 4-1/2" tubing and cut and pull the 7- 5/8" casing from —3000' MD. A bridge plug will be set above the 7-5/8"casing stub.A whipstock will be set on the bridge plug and a window will be milled in the 10-3/4" surface casing. BP is requesting a variance from 20 AAC 25.112 Well Plugging Requirements c.1.E. The objective of the L-205A sidetrack is to drill a slant well near the existing L-205 laterals so that their remaining reserves may be accessed via hydraulic fracturing and produced through the new sidetrack. For this reason, it is not desired to abandoned the existing laterals with cement. Instead of cementing individual laterals, it is proposed that a bridge plug will be set in the 4-1/2" scab liner(above all lateral junctions) with 25' of dump bail cement on top to satisfy abandonment requirements. However, it is proposed to set the bridge plug at —4100' MD which is greater than the 50' maximum above perfs as stipulated in 20 AAC 25.112.c.1.E. The shallower set depth is proposed due to obstructions encountered near the L5 junction and to help ensure successful setting of the plug. Note that the 4-1/2" scab liner has been fully cemented and that the top of annular 7-5/8" casing cement is estimated at—4000' MD. Thus, the dump bail cement at—4100' MD will complete a full lateral cement barrier above the Schrader reservoir.

A depth somewhat closer to the junction would be desirable. Thanx, Victoria From: Raese,J.

Note that this drift run was performed two years ago with tools slightly under gauge to the OD of the proposed 4-1/2"CIBP. My intent in proposing to set the CIBP at 4100'was keep away from the obstructions in order to avoid issues setting the CIBP.That being said, it is likely possible to set the CIBP deeper than 4100'. Do you have a preferred depth range? The 7-5/8" annular TOC estimate was determined using volumes recorded during the cement job with an assumed 30%open hole washout(typical for our intermediate sections). No losses were noted during the job.

Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of"Suspended." Step Task Responsible 1 The initial reviewer will check to ensure that the "Plug for Redrill"box Geologist in the upper left corner of Form 10-403 is checked. If the "Abandon" or "Suspend" boxes are also checked, cross out that erroneous entry and jinitial it on both copies of the Form 10-403 (AOGCC's and operator's copies). 2 If the "Abandon"box is checked in Box 15 (Well Status after proposed Geologist work) the initial reviewer will cross out that erroneous entry and initial then it on both copies of the Form 10-403 (AOGCC's and operator's copies). Instead, check the "Suspended"box and initial that change. Drilling Engineer The drilling engineers will serve as quality control for steps 1 and 2. (QC) 3 When the Stat Tech receives a Form 10-403 with a check in the "Plug Stat Tech for Redrill" box, they will enter the Typ_Work code "IPBRD" into the History tab for the well in RBDMS. This code automatically generates a comment in the well history that states "Intent: Plug for Redrill." 4 When the Stat Tech receives any Form 10-407, they will check the Stat Tech History tab in RBDMS for the "Intent: Plug for Redrill"code (IPBRD). If present and there is no evidence that a subsequent re-drill has been COMPLETED, the Stat Tech will assign a status of SUSPENDED to the well bore in RBDMS no matter what status is listed on the 10-407. The Stat Tech will also change the status on the 10-407 form to SUSPENDED, and date and initial this change. If the Stat Tech does not see the "Intent: Plug for Redrill" comment or code, they will enter the status listed on the Form 10-407 into RBDMS. 5 When the Form 10-407 for the redrill is received, the Stat Tech will Stat Tech change the original well's status from SUSPENDED to ABANDONED. 6 The first week of every January and July, the Stat Tech and one of the Stat Tech Geologists will check the "Well by Type Work Outstanding"user query Geologist in RBDMS to ensure that all of the Plug for Redrill wells have been handled properly. At this same time, they will also review the list of suspended wells for accuracy. • Image Project Well History File Cover Page XHVZE This page identifies those items that were not scanned during the initial production scanning phase.

We wanted to stay with the naming convention of naming the laterals in the order in which they are drilled and that is why we proposed the changes below. I think this will make it a lot less confusing when looking back at post well data. Please let me know which convention you wish to go with. Thanks for your consideration. Scott From: Kolstad, Scott R Sent: Tuesday, June 10, 2008 4:49 PM To: 'Maunder, Thomas E (DOA)' Subject: L-205 Ll-Ol name change permit 208-058, 208-055, 208-056, 208-OS7 Tom, Due to some difficulty running past the L-205 aluminum billet liner top we would like to make some changes to the location of the L-205 L1 liner top location and exit point for the Obd lateral that was permitted as L-205 L1-01. This will intern change the well bore names from the permitted names. Well targets will remain as permitted. The L-205 L1 liner top will be run to 5,750' as depicted in the attached schematic and will cover up the L-205 billet to reduce the risk of further problems with the L-205 billet. This will change the KOP for the Obd lateral to kicking off from the L-205 well bore and not the L-205 L1. We would like to propose the following changes to the naming of the Obd lateral and subsequent laterals.

The permit is for a new wellbore segment of existing well PBU L-205, Permit No 208- 053, API 50-029-23388-00. Production should continue to be reported as a function of the original API number stated above. This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. When providing notice for a representative of the Commission to witness any required test, contact the Commission's petroleum field inspector at (907) 659-3607 (pager). Sincerely, Daniel T.

The intermediate hole well control equipment consisting of 5000 psi working pressure pipe rams(2), blind/shear rams, and annular preventer will be installed and is capable of handling maximum potential surface pressures. BOP equipment will be tested to 3000 psi. The BOP test frequency will be conducted on a 14 day frequency, with a function test every 7 days. Except for significant operational issues that may effect well integrity or pose safety concerns, an extension to the 14 day BOP test period should not be requested.

Any metal cuttings will be sent to the North Slope Borough. • Fluid Handling: Haul all drilling and completion fluids and other Class II wastes to DS-04 for injection. Haul all Class I waste to Pad 3 for disposal. Varience Request: • To avoid the risk of plugging the flow line with large rocks and wood encountered while drilling surface hole, it is requested to drill without a flow paddle for the first portion of the surface hole. While the flow paddle is removed from the flow line, PVT alarms will be used and the pit levels accurately monitored for any pit gain. Also, a visual check will be made during connections by looking down the riser to ensure the well is not flowing. After returned debris that could plug the flow line diminishes the flow paddle will be reinstalled. 6 L-205 Permit to Drill 3/25/2008 • Drilling Hazards and Contingencies POST THIS NOTICE IN THE DOGHOUSE Well Control A. The Schrader in the target fault block is expected to be normal pressured at 8.5-8.6 ppg EMW. II. Hydrates and Shallow gas A. Gas Hydrates are expected at L-pad from the SV5 thru the SVi sands below the base of the permafrost. Setting casing through the SV1 should keep hydrate exposure from extending past the surface hole. Recommended practices for drilling hydrates should be followed in the surface hole. Occasionally hydrates are encountered below the SV1. III. Lost Circulation/Breathing A.
