Commission Anchorage ~,4d~ Enclosed please find a spreadsheet with a list of wells from the Kuparuk field (KRi1). Each of these wells was found to have a void in the conductor. These voids were filled with a corrosion inhibitor, engineered to prevent water from entering the annular space. As per previous agreement with the AOGCC, this letter and spreadsheet serves as notification that the treatments took place and meets the requirements of form 10-404, Report of Sundry Operations. The corrosion inhibitor/sealant was pumped between August 19 & 21, 2007. The attached spreadsheet presents the well name, top of cement depth prior to filling, and volumes used on each conductor.

It appears that no harm was done despite drilling the additional measured footage. Your FIT plot indicates that there was no leakoff. Hopefully, the remainder of the well will go smoothly. Keep us informed if any other difficulties are encountered. Tom Maunder, PE AOGCC Billingsley, Tim A wrote, On 10/28/2005 2:28 PM: Tom, Attached is the sequence of events regarding the last few days at Doyon 15 and the drill pipe tally errors which resulted in drilling 119' MD (15' TVD) of new formation below the 7-5/8" intermediate casing before stopping to do the FIT. Also attached is the 12.5 ppg EMW formation integrity test conducted at 14,919' MD which passed. We are drilling ahead at 15, 200' now and doing well.

This resulted in drilling out the float collar and to within 26' of the float shoe before doing the 7-5/8" casing test which failed. Then the 7-5/8" test packer was run and verified that the leak was out the shoe and not in the 7-5/8" casing. The second drill out assembly drilled with the incorrect tally and ended up drilling 119' instead of 40' of new formation before the mistake was discovered. The FIT to 12.5 ppg was conducted at that time and a 12.5 ppg EMW FIT was successful. A summary of events is as follows: 1 Drilled 9-7/8" hole to 14,800' with correct 5" drill pipe tally. 2 Ran 7-5/8" casing with correct tally, float shoe at 14,781', float collar at 14,691'. 3 Pumped cement, plug did not bump. (shut down pumping due to calculated displacement of volume to float collar plus % of float track). 4 Drilling assembly with incorrect 4" drill pipe tally tagged top of cement at 14,598' (correct depth was later determined to be 14,683') 5 Drilled up cement down to incorrect depth of 14,670' (correct depth later determined to be 14,755' which is 26' above the 7-5/8" shoe at 14781') 6 Performed 7-5/8" casing test to 3500 psi. Test failed, pressure Peaked off to 1100 psi in 40 min. 7 POOH with drilling assembly, found a +6.3' correction to drill pipe tally due to jars not being fully included in tally (there will be a larger correction made late in step #9 below) 8 Ran 7-5/8" test packer and tested casing good at 14,660' (correct depth later determined to be 14,739') Leak was below test packer depth. 9 Ran drilling assembly, drilled up cement and 40' of new formation to 14,840'. Drill pipe tally mistake was discovered by LWD resistivity tool logging the bottom 7-5/8" casing shallower than expected. Checked tally and determined that some Lo-Tad torque reduction subs were not included in 4" drill pipe tally. Correction was +78.69'. Corrected tally shows casing shoe at 14,779' on LWD log which is real close to casing tally of 14,781'. Corrected tally shows total depth drilled to was 14,119' or 119' of new formation instead of the intended 40' of new formation. 10 Performed FIT test to 12.5 ppg EMW by pressuring up to 1100 psi (TVD = 6508', MW=9.2 ppg), no break over on the increase in pressure up to 1100 psi and lost only 30 psi in 10 min after the pumps were shut down. Plan Forward: Drill 6-3/4" horizontal production hole. Run 4-1/2" slotted liner, run 4-1/2" tubing.

Good luck with the continuing operations. Send a message if further issues develop. Tom Maunder, PE AOGCC Billingsley, Tim A wrote, On 10/27/2005 10:49 AM: Tom, On 1C-28, the 7-5/8" cement job went well but we stopped the displacement at the calculated volume plus 1/2 of the shoe track without bumping the plug. (There was 14,781' of 7-5/8" casing so a large displacement volume of 654 bbls. If the mud pump efficiency was a little off, then the calculated displacement volume might have been a little short) The drilling assembly drilled up cement and plug from 14,598' to 14,670', just above the float collar at 14,691'. The casing was tested at this point and the 3500 psi test pressure leaked to appx 1200 psi in 30 min. A 7-5/8" test packer was run to 14,660' MD (the float collar is at 14691' and float shoe at 14,781') and tested the 7-5/8" good to 3500 psi above 14,660'. The leak must be going out the bottom of the shoe. The problem probably occurred because we did not bump the plug on the cement job and then drilled up the plug and cement from 14,598' to 14,670' before testing the casing. There might be small channel on the high side of the inside of the 7-5/8" casing due to the 73 degree hole angle. This allowed the test pressure to exit out the bottom of the shoe and into the contaminated rathole and into the formation between the shoe at 14,781' and the TD of the 9-7/8" hole at 14,800'. As we discussed yesterday, we will proceed with drilling out the rest of the cement inside the 7-5/8" shoe track and 20' on new formation. Then perform a FIT to 12.5 ppg EMW and proceed with drilling the production hole. We should have pressure tested the casing before drilling up any cement or the top plug and then probably would have obtained a good casing test.
