The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations.

Subject: 16-20 (PTD #1852850) UNDER EVALUATION for sustained casing pressure - TxlA Communication Attachments: 16-20.pdf Hi all, Well 16-20 (PTD #1852850) has been found to have sustained casing pressure on the IA. The wellhead pressures were 2050/2040/300 psi on 08/05/07. A TIFL failed on 08/08/07 on pressure build up. The well has been classified as Under Evaluation and placed on a 28 day clock. The well may be produced once Flow Station 2 begins operations again. The plan forward for this well is as follows: 1. D: TIFL - FAILED 2. S: Set DGLV 3. D: Re-TIFL A wellbore schematic has been included for reference. «16-20.pdf» Please call with any questions. Thank you, jlnna (j)u6e, æt£.

Numbering starts with the first full joint below the Christmas tree. PUt' IOINTS: are designated by decimal numbers. For example, joint 32.1 represents the first pup joint below joint no. 32. SPECIAL TOOLS & NIPPLES: are designated by letters. For example, "B" is the second special tool or nipple from the top of the well. GAS LIFT MANDRELS: are numbered down from the top, as shown: GLM (1), GLM (2), etc. TABULATION SYMBOLS We use a circle as the basic tabulation symbol. The Kinley Caliper records the simultaneous action of all fifteen or thirty feelers. Our survey, therefore, has either 15 or 30 lines. These lines provide a view around the circumference of the inner surface of the pipe. A complete circle on the tabulation sheet indicates that at least 14 of 15 feelers, or 28 of 30 feelers found tubing wall reductions at the same depth in the well. This would be described as a ring. The number of feelers that indicate tubing wall reductions at the same depth is also noted on the tabulation sheet. For a 1,5-Feeler Caliper F-] 3 to5 [-'! 6 to 9 F-] 10 to 13 F"] 14 to 15 For a 30-Feeler Caliper D6toll [~] 12t019 D20t027 028t030 MEASUREMENT SYMBOLS PIT- A number alone represents the depth of penetration, expressed in hundredths of an inch, of the deepest pit. In this example 0.08". A groove around ~ pipe, found by 14 of 15 feelers or 28 of 30 feelers. The number Inside the cirde represents the maximum depth of the ring, expressed in hundredths of an inch. A PARTIAL RING - A groove around the pipe, found by 3 to 13 of 15 feelers or 6 to 27 of 30 feelers. The number inside the partial drcle represents the maximum depth of the ring, expressed in hundredths of an inch. MINOR DAMAGE - Indicates a "minor" amount of damage that is not severe enough to warrant measuremenL D NO COMMENT - Indicates no damage was found in that joint. Arco (Alaska), Inc. Prudhoe Bay, AK Drill Site #16-20 July 3, 1994 Survey No. 23998 T-30 Chart No. M1397 This is the first survey of this well to be made with the Kinley 30- Feeler Microscopic Caliper. The condition of the internal surface of the ~ 1/2" 17# LTC tubing in the well, from 0' to 10,040' (WLM), is covered in this report. The deepest penetration recorded in the survey is in an area of corrosion located in Jr. #235. This penetration measures 0.18" or 59% of the tubing wall thickness. A cross-sectional drawing and a picture enlargement of the recordings for Jr. #235, at the location of the penetration, are included in this report. The condition of the tubing surveyed and analyzed ranges from good to poor with respect to corrosive damage. Indications of damage are recorded in the entire tubing in the forms of scattered pits, areas and lines of corrosion. As illustrated in the Body Corrosion Profile, the damage is recorded throughout the tubing, with the deeper penetrations below Jt. #216. Indications of corrosive damage are recorded in the pup joints above and below the GLM's and tool assemblies. The deepest penetration recorded in these areas measures .09" or 30% of the tubing wall thickness and is recorded in the form of corrosion in the lower pup joint of GLM's (5), (6), and (7). The corrosive damage that is recorded in the interval between Jr. #'s 70 and 166 appears circumferential and widespread. Picture enlargements of the recordings for some of the joints in this interval are included in the report. A line of corrosion is recorded between Jr. #200 through Jr. #245. In this interval, along with the line of corrosion, there appears to be some general corrosive activity, as well. In this interval, the line of corrosion measures deeper than the general areas of corrosion and it is difficult to determine the exact location of the nominal I.D. in some of the joints. The penetration values given for some of the joints in this interval are the best estimate of corrosive damage and may be slightly different than the actual wall loss.

After reaching TD, logs will be run across selected intervals. The well will be completed using a workover rig at a later date. A string of 5-1/2", 17#, L-80 tubing will be run and set above the Sadlerochit. A downhole safety valve will be installed and tested upon completion of the job. Non-freezing fluids will be left in all uncemented annuli within the permafrost interval. Selected intervals will be perforated in the Sadlerochit formation and reported on subsequent reports. Reserve pit fluids will be disposed of down the 9-5/8" x 13-3/8" annulus of this well. The 9-5/8" x 13-3/8" annulus will be left with a non-freezing fluid during any interruption in the disposal process. Upon completion of the disposal process, the annulus (see attached sheet) 23.

The log fil~s represent the aggregate nms of ARCO's high resolution induced spec ,uT~l gamma r~'tool in Prudhoe Bay wells DS3-6, DS3-9, and DS 16-20 in late spectra a~q~ with an AR~-- built logging tool consisting of a Kaman Instruments A- 320 neutron generator nm a~.,KHz with a 10% duty cycle, a high resolution germanium detector and ~dowrdiol~IlS-channel analyzer. Loading the Data/rom Tape \ The tape is a VAX/VMS file stru~ tape written at 1600 bpi. To copy the data from it: 1. Physically mount the tape. 2. Issue the VMS tape mount command: $ mount msa0:/den=1600 SDATA where SDATA is the tape label. 3. Copy the files to the desired destination, for example: $ copy rosa0:*.* duc9:[gary.dataout]*.* RECEIVED tu:~,ca Oil & Gas Cans.

Note that the second column is the length of the file in blocks and that the data files are fairly large. Contents of Data Files- Each data file is composed of a series of unformaned direct access binary records. The structure of the records is described in more detail below. Generally the odd numbered records contain inelastic scanerring gamma ray ~ and the next highest even numbered spectra contain the corresponding czpture gamma ray spectra. In a few cases, specifically DS3-9 records 1-150, the inelastic records are empty. This signifies that the generator was not firexL These particular ~ are passive (K U Th), token to evaluate nann-ally radioactive scale in the well bore. A few of the records are labeled with rough calibration numbers to help start the analysis process. The calibration numbers stored in the data records are not likely to be correct. Ftmher more the calibration drifts a little with time, particularly near the end of the detector warm up cycle and depends on the parficnlar hardware units in use. To use the calibration numbers, multiply the channel number (which is just the subscript of the array element) times the slope aha add the offset. For example Energy(KeV) = m * channel_number * b.

(UNUSED) [1_3956] Actual Specmxm Sample Access Program The tape also contains a sample FORTRAN program for accessing the spectral records, named RETRIEVE.FOR. It requires the include file, SPCTRM.GLB, which contains the actual data structure of the records. It is a simple minded program that prompts for spectral log file name and record number, then writes the results to a formatted ASCII file, one value per line. See the source code for more detail about what is written out and how the spectral records are accessed. Questions or Problems: Contact: Gary D.
