Attempt to wash out fill currently across the perforations at 11,607' MD. Cleanout fill to the bottom of the perforations or as deep as possible. Lay a cement plug from the PBTD to at least 100' above the top perforation (top perforation at 11,600' MD -- cement top no deeper than 10,500' MD). 4. RU slickline unit. RIH and confirm cement top at least 100' above top perforations. Note: Tag to be witnessed by AOGCC representative. 5. RU E-line and make a tubing cut at +/-10,500' MD based on completion tubing tally. 6. Circulate well over to seawater and freeze protect well to 2000'. 6. Bleed tubing, inner annulus, and outer annulus to 0 psi. 7. Set 5-1/2" BPV and prepare Pad for RWO. 8. MIRU rig. Pull BPV. Circulate out freeze protection. Pull 5-1/2" tubing. 9. RIH with a 9-5/8" bridge plug and set at 10,300' MD. Test w/ 15,000#'s of pipe weight. After cutting a 60' section from the 9-5/8" casing from 10,050' MD to 10,110' MD, a kickoff cement plug will be laid with the base of the plug 100' MD below the section at 10,210' MD.

The 5½" tubing will be pulled and the packer retrieved. A fluid den- sity/HP tool left in the hole will be retrieved at this time. A retainer will be set at +11,550', above existing perforations at 11,750-11,705' and 11,695-11,644'. A ceme-nt squeeze using cement w/tracer will be done through these perfor, tions. The re- tainer and cement will be drilled out and a GR/CCL/CBL run to evaluate the squeeze. We / will then resqueeze if necessary. The well will be completed with 5½" plastic coated ~ tubing with gas lift mandrels. The well will be reperforated after the rig has been released. A 13-5/8" 5000 psi RSRRA BOP stack will be used on well work performed by the workover ri . The BOP equipment will be pressure tested each week and operationally tested each trip. A non-freezing fluid will be left in all uncemented annuli within the perma- frost interval. Necessary provisions for subsurface safety equipment will be run in the completion string. A 5000 psi WP wireline lubricator, tested to working pressure, will be used on all wireline work. The downhole safety valve will be installed and tested upon conclusion of the job.

A non-freezing fluid will be left in all uncemented annuli within the permafrost interval. Selected intervals within the Sadlerochit will be perforated and reported in a subsequent report. A 5000 psi WP wireline lubricator, tested to working pressure, will be used on all wireline work. Well will be flowed to production facilities during perforating & testing. The downhole safety valve will be installed and tested upon conclusion of the job. IN ABOVE SPACE DESCRIBE PROPOSED PROGRAM If proposal IS to deepen g~ve data on present productave zone and proposed new productive zone. If proposal m to drill or deepen d~rec~onally, g~ve pertment data on subsurface locations and measured and true vertical depths. G~ve blowout preventer program. 24.

To improve the readability of the Well History file and to simplify finding information, information of this nature is accumulated at the end of the file under APPENDIX. No special effort has been made to chronologically organize this category of information. _Basic The Basic information Tape (BIT) is a binary, partially multi- plexed Tape containing up to 20 daza curves. The daza samples are represented as IBM, 32-bit floating point numbers. The tape consists of a 2?6 byte heading record followed by a series of data records whose length is defined in the heading record. The last daza record is followed by two end-of-files. The tapes are 9 ~rack, 800 bits per inch. ,_ Headin~ Record The heading record contains the information necessary to recover the curve data from the data records and some identification information. 1. The Epilog Computation Center (BCC) number is a unique number assigned at one of the Dresser Computer Centers. Any questions regarding the data should, if possible, include this number. 2. Conpany name - Well name. These are free format fields used to identify the well. 5. The number of curves (N) is designated as a 16 bit binary integer nmmber. This number must be less than or equal to 20. It gives the number of curves of data that will be in the data records. 4. Curve names.--Each curve is designated by a 4 character name. A list of Dresser Atlas standard names is given in the appendix. These names appear in the order in which the data appears in the data record. 5. The starting and ending depth gives the first depth for which there is data on the tape and the last depth respect- ively. ;'~nen ~he starting depth is snalier than the end- ing depth the data is recorded downward. With field data, the ending depth may be snal!er since the data is recorded from the bottom of the well upward. The ending depth may be given as 0 or 99999 when it is not known during recording; this occurs on BIT tapes recorded in the fie Id. 6. Level Spacing (L). This field designates the depth incre- ment be+~.'~ -' ~ ..... ~ne data sar. o s the data samoles are taken at regularly spaced depth increments. 7. Nu...be."= ~ ~f samples (F). This field gives the number of sam- ples of each curve recorded in each. data record. This number will be less than or equal to !2S. DATA RECORDS · The samples in the data records are recorded as floating point members (IBM standard). This consists of a sign bit, 7 bit exponent and a 24 bit mantissa normalized to the nearest 4 bits. . sign bit. The exponent is biased by 40 . Th~s, 41100000 represents the number 1.0. ~G ~G The data record consists of N · F - 4 bytes of data where N is the number of curves and F is the number of samples of each curve. The first F samples in the record will be of curve !, the next F samples will be of curve 2, etc. . Each record will contain data for F · L feet of data, where L is the level sds . c_n= lne current standard usage at Dresser data center is- Level spacing = L = .5 feet Samples per record = F = 125 Thus each record represents 62.5 feet of data. These numbers are given as an example only, however, since Llnd F may vary from tape to tape, and will certainly be different for BIT tapes recorded in. the field.
