BOX 7034 ANCHORAGE, ALASK~ Dear Mr. Tabl er: In your May 27 letter you requested that the confidentiality of all reports and information from the subject well be extended pursuant to AS 31.05.035(c). The bottomhole location of this well is situated approximately one-half mile from unleased state land in northeastern Alaska. Data from the well are currently scheduled to be released on September 7, 1986. Under ll AAC 83.153 if the commissioner finds that reports or information required under AS 31.05.035(a) contain significant information relating to the valuation of unleased land within a three-mile radius of the well, the commissioner .will, upon the written request of the owner of the well, keep the reports or information confidential. The nearby unleased land is currently scheduled to 'be offered "exempt" in proposed Lease Sale 51 (Prudhoe Bay Uplands) in January 1987. Under ll AAC 83.153(b)(2) reports or information for which extended confidentiality is requested or has been granted under AS 31.05.035 will not be eligible for extended confidentiality when the unleased land within a three-mile radius of the well from which the reports or information are obtained is offered in a competitive lease sale, but receives no bids greater than or equal to any minimum bid established for that sale. Therefore, under the departmental delegation of authority I agree to extend the confidentiality of the Union E. de K. Leffingwell Well information until 30 days after the first lease is issued as a result of proposed Lease Sale 51 (Prudhoe Bay Uplands). By copy of this letter I am directing the Alaska Oil and Gas Conservation Commission (AOGCC) to extend confidentiality of data from the Union E. de K. Leffingwell ,~.Well until further notice.

Leff- ingwell ~l well located near the Canning River, request, pursuant to Alaska Statute 31.05.035 (c), that the Commissioner find the required reports and information pertaining to said well, which have been submitted to the State, contain significant information relating to the valuation of unleased land in the vicinity. This well lies within 3 miles of unleased state acreage which is not on the present Oil and Gas Lease Sale schedule. A portion of this acreage block has not been offered for leasing since the drilling of Union's well. Rroprietary information derived from the drilling of this well also has significant application to the evaluation of unleased lands to the east on the Coastal Plain of the Arctic National Wildlife Refuge (ANWR).

A liner will be set through the sidetrack depth as mechanical protectiom An appropriate plaque will be provided to Union Oil Company of California for attachment to the wellhead. CER:md cc: H.

Monday, Au~_ st 6, 1984: The cement above the 7" retainer was ~agge~ ~t 13,555-feet with 30,000 pounds. The retaining was pressured tested with 1,500 pounds of pressure for 15 minutes with no pressure loss. The liner lap plug (between the 9 5/8" casing and 7" liner) (see drawing). A cement retainer was set at i,~1=,757 feet and 75 sacks of cement was set on top o~the retainer.~ retainer was pressure tested to 1,500 for 15 minutes with no pressure loss. Neat cement with 3/10 of 1% R-5 was used. Tuesda~_A_ugus_t 7, 1984: On duty; waiting for the drilling con- tractor to'replace ~A~ing on main drawworks shaft.. Wednesday, August 8, 1984: The surface plug, a cement plug was set ~ /-00 feet With 42 sacks of Cold Set II cement. I filled out the AOGCC plug and abandOnment report which is attached to this report along with a casing drawing of the retainers with cement on top of them. In summary, ! witnessed the plug on the open hole isolation, the 9 5/8" to 7" liner, lap plug and the surface plug on Union Oil's Leffingwetl No. 1, Arctic Alaska Drilling Rig 6. Attachments ~ ....

Leffingwel! #1. The hole conditions are excellent and the~'e has been no evidence of abnormal pore pressures. The present mud weight is 9.8 ppg and the 13 3/8" casing shoe at 4030' has been tested to a 14.2 ppg ENW. The originally proposed 9 5/8" casing setting depth of 12,500' was based on an anticipated pressure Transition Zone beginning at + 12,000' with a formation pressure at ± 12,500' of 13.0 ppg mud weight equivalent. This transition zone has not yet occurred and, in fact, may not at all. It is proposed to extend the 9 5/8" casing setting depth either to such a point that deteriorating hole conditions or elevated mud weights (12.5 to 13.0 ppg) dictate early cased hole protection or, if conditions remain normal, to 16,200' , si,.~~~ District ~dg Superintendent D~,. oa/19/sa Th~ below for Commission use ¢ ~ ?*-, ~t ~ns of Approval, if any: .... - .'

Wednesday, February..29, 1984: Standby to witness function test of 20~' diver'ter system. Th'e 20" casing was cemented w/3725 sacks cold set #3 high yield cement--and 900 sacks cold set #2 low yield. Cement dropped out of sight. Thursday, M~rch 1, 1984: Standby to witness function test of the 20"-diverter system. A top cement job of 250 sacks of cold set ~2 was performed at 12:15 am. The cement was dropping out again. After observing cement for 15 hours another top cement job of 118 sacks of cold set #2 was performed. Cement was still dropping out at one foot an hour. Friday, March 2', 1984: Before the function test of 'the diverter ~~-~he two ~alve~ that divert 'the gas and/or fluids in different directions according to the prevailing winds were upside down and frozen into the ground and could not have operated in that manner when hooked up with the 30" diverter. I informed Larry McCalister supervisdr for Union Oil that the diverter valves were not appro- priately installed, he' immediately gave orders to the Pool Arctic tootpusher to turn the valves upright to the correct position, this was performed. I witnessed the successful function test of the 20" diverte~/'syStem according to A.O.G.C.C. specifications. ~,~Fnen ! left the location, Union Oil was preparing to perf:'~.~!~-" / -" another top cement job. - In summary, I witnessed a successful function test of the system on E. de K.
