The upper leak is in a 4-5' interval with 25-35% wail loss in the casing, probably associated with casing wear. We're still looking at trying to determine what or when the wear may have occurred. It was isolated to just this one spat.

Been chasing things all morning. ,~~~ The 13-318'" x 9-518" annulus is full of diesel right now.... we're actually pumping some additional diesel down the backside as we speak to ensure it's full after doing some injection testing this morning. We're going to pump our normal Arctic Set 1 cement we use far surface casing since we're so shallow (2000 - 2300' TVD) and ensure we spot cement across the leaks prior to circulating cement to minimize any brine in the annulus (we have 9.6 in there now). We've been working on a plan where we actually squeeze the upper and lower leaks together.., figure it can't hurt to get cement in the bottom leak as well and this will save us a drill out of a plug. This will also help get cement across the upper leak before opening up the backside and taking returns to bring the cement into the annulus. The upper leak takes fluid much easier than the lower as expected (the tower's already been squeezed a couple times as you probably recall) which is fine since it's our primary focus.

As we discussed this morning, I was able to find some prior messages regarding the leak at/near the liner hanger and the remaining work of drilling and equipping the laterals was conducted according to the plans transmitted in those messages. At this point, it is probably appropriate to designate this as an "operational SD" and a sundry is necessary. My reasoning is that the rig will be changed and there is a some amount of new work that will be planned for 3 S to accomplish. Starting the 3 S work will also require submitting a sundry to transmit the work plan. Based on the information you have provided, you may continue with the work to secure the well and move off the rig. I will look forward to receiving the sundries. Sharon, just send in theforms. I will attach this message as back up. Tom Maunder, PE ~p-3 AOGCC McKeever, Steve wrote, On 9/9/2005 10:50 AM: Tom- As we discussed this morning, we are in the process of suspension operations on our well 1E-170, in anticipation of moving off Doyon 15 and completing the work with Nabors 35 later this month.. I have attached a summary of our recent Doyon 15 operations on this well. Summarizing those operations, we successfully ran a liner into the upper lateral and ran the LEM assembly into the upper hook hanger. This LEM assembly had a joint of 7" casing just below the ZXP packer, allowing us to set and test a retrievable bridge plug in that joint of 7", providing full hydraulic isolation from all three laterals. Following the test of the bridge plug with a retrievable test packer, the wellbore above the plug was displaced to 9.6 ppg NuCI brine, and the 3-1/2" work string and test packer were hung off from the tubing hanger. Currently we are preparing to nipple down the BOP, nipple up and test the tree, and move off the well. Nabors 3s will move onto the well later this month. Once they have nippled up and tested their BOP stack the plan is to: • Re-locate and confirm the presence of a single leak in the 9-5/8" casing from approximately 4858' - 4860' MD (x-over below the 9-5/8" liner hanger) using the 3-1/2" work string and test packer currently hung off in the well as a kill string. 1 of 2 9/9/2005 1:55 PM xe: i~-i iu li-i anu L~~ suspension vpera~iv~a rian • • Install a Baker expandable casing patch over the 9-5/8" casing leak from '' 4858' - 4860' MD.

The latest test is 690 psi on top of the mud column you have in the hole. When Pat and I talked, it was indicated that the EMW calculated with that pressure and the mud column 14.8 if I remember correctly. That was better than 2 ppg greater than the LOT at the 13-3/8" shoe and (assuming 9.0 ppg mud) better than 5 ppg greater than the MW. It is not likely that further applications of cement will improve the pressure tollerance. The plan to ultimately set a patch across the leak is a sound one. You are proposing to continue drilling the laterals as planned and then install the patch when the laterals are complete. Since your 12-1/4" hole penetrated all the sands of the West Sak without experiencing any pressure problems, there is little risk that drilling the laterals will result in encountering higher pressures than previously experienced. Your plan to proceed is acceptable. Pat, please contact me on Monday for an update. Feel free to call if there are additional developments.

From the pressure response, it appears that the leak was successfully squeezed. 2400 psi at 2 bpm isn't bad at all. I agree that testing the casing/squeeze to a lower pressure due to the potential to damage the tieback is appropriate at recommended by your equipment provider. The MASP lies between the 1000 and 1500 psi test pressures that have been proposed. The MASP is calculated with a gas gradient of (0.1 psi/ft) making the calculated pressure high and therefore conservative. In normal drilling operations well pressures should not approach this value even when a well control situation is considered. The ultimate test pressure value is CPAI's to determine, but I agree with what appears to the minimum of 1000 psi. Tom Maunder, PE AOGCC NSK Fld Drlg Supv wrote: Tom, Mike has called the rig and they have agreed to pressure testing the 9 5/8" casing to 1000 psi in order to prevent any further damage to the suspect crossover. The squeeze operations took 20 bbls of cement with all that volume going into the 13 3/8" X 9 5/8" annulus as calculated from the displacement. At 2 bpm the pressure stepped up progressively to +/-2400 psi making it appear that a good squeeze was obtained on the lap area. The leakoff tests in this area of the West Sak have normally been in the range of 450 to 600 psi surface pressure with a 9.0 ppg mud, which is what they should be drilling out with. Once the three laterals have been drilled and all the liners are run a 9 5!8" casing patch will be run across the area of the damaged crossover for improving casing integrity in the future. Upon the successful execution of that procedure the ESP completion will be run.

The leak was determined to be in a collar on a crossover pup joint directly below the liner hanger. Last night we squeezed the: leak with 20 bbls of Class "G" cement. We pumped 18 bbls through the Icak and left 2 bbls inside the 9-5/$" casing. The volume below the RTTS packer to the leak was slightly over 4 bbls. The 9-S/8" ~ 13-3/8" annulus volume from the leak to the 1.3-3/8" shoe was 11.9 b61s. We are currently picking up our BH~1 to @ in. and drill out what cement is left inside the 9-518" casing. Casing movement calculations from Baker indicate that if we pressure to 3,000 psi we tiviil be putting the rnaxi_muan load on the tieback string packer. I am recommending that yve onl:y pressure to 1,500 psi with the plan to place a casing patch across the leak area. after we have .~ni.shed placing into the well all the liner hook equipment and :lateral entry equipment ghat «•e :hare to run. i_n th.e ~.vell. The casing patch is to ensure future casing integrity as a back up to the cement squeeze.
