Box 196612 Anchorage, AK 99519-6612 Attention: Nabors 2ES Drilling Engineer I have compiled a summary of Anadrill's performance on DS 18-9A, Nabors 2ES. SERVICES PROVIDED Directional slim hole MWD (SLIM 1) was used to kickoff the well and provide tool face orientation and surveys. OPERATING STATISTICS Total SLIM 1 operating time (pumping over 150 gpm) for the well was 326 hours. Total SLIM 1 footage was 2595'. JOB PERFORMANCE SLIM 1 can transn'fit two types of surveys. A long survey contains all the raw sensor data and can be used to determine magnetic interference. In a short survey the survey is calculated down hole and only drift and azimuth are sent to the surface. On the kickoff the tool was programmed to send long surveys only so we could determine when the surveys were free of magnetic interference. On subsequent runs the tool was programmed to send long or short surveys as needed. If the survey station was to be calculated a long survey was sent. If it was just a 30 foot check survey a short survey was sent. A total of 53 surveys were taken of which the directional driller used 26. Some of these surveys were recovered from the tool memory on the last two bit runs because the pulser was jammed by nut plug and no surveys were transnfitted to the surface. We encountered some problems due to excessive wear on the internal solenoid coupler pins. These pins are machined to exact specifications, and if they become grooved from wear, then latching problems occur with the pulsing device. On the bit runs that we did experience real time survey problems, we were still able to provide recorded surveys when the tool memory was dumped at surface. The problems began when the flowrate was increased after going from a mill tooth bit to a PDC bit. The 1 7/8" pulser configuration was used so that the Slim 1 tool could be wireline retrieved through the 2 1/4" ID jars. When the mill tooth bit was being used, the flowrate was approximately 240 gpm which is the optimum flowrate for a 1 7/8" pulser configuration. When the PDC bit was used, the flowrate increased to approximately 260 gpm which is at the high end of the operating spectrum for the 1 7/8" pulser configuration. This flowrate put excessive torque on the pulser configuration, and this in turn caused premature wear on the solenoid coupler pins. One option was to use a 2 1/8" pulser configuration with the higher flowrate. This would have alleviated the pin wear problern, but we could not have wireline retrieved the tool through the jars. Our final solution was to machine down the 2 1/8" pulser configuration to 1.7/8". This fixed both problems. One, by machining down the pulser, the torque was decreased and therefore the premature pin wear was reduced. Two, the Slim 1 tool was wireline retrievable through the 2 1/4" ID jars. Since this situation occurred, Slim 1 manufacturing has developed a 1 7/8" pulser configuration to handle flowrate ranges from 190 to 300 gpm, and also handle approximately 10 lb/bbl of medium nutplug (well dispersed). Anadrill appreciates your patience during the time which we experienced problems. We feel confident that we have identified the problem, and that we have procedure in place to prevent its reoccurrence. As an extra precaution, we are bringing in a Slim 1 expert from our Calgary manufacturing facility to perform an in-depth check on the tools.

Cor¢l[ffission AJ~chorage ~.~q:. ROPOSED REDRILL PROGP~'~'~ WELL 18-9A OBJECTIVE: The primary objective of the 18-9A redrill is to return the well to production by drilling a new hole to a location approximately 900' to the northwest of the current BHL. Justification for the move is found in the near wellbore faulting of the existing well which is believed to be responsible for three failed GSO attempts and severely limits further remedial options. The proposed redrill will be in a better position to recover reserves from both the targeted 18-T location and the existing drainage area; current recovery from 18-9 is estimated to be only 2.3% of the OO1P. Well 18-9 is currently shut-in following the failed September 1991 GSO attempt. It is believed a sidetrack of the well is preferable to a fourth squeeze attempt given the 200 bbls already behind pipe in 1 8-9 and the poor squeeze record for DS 18 in general (1 success in 10 attempts for CT squeezes). Post-sidetrack production rates are estimated at 1300 BOPD at 0.0% WC and 1200 GOR. The scope of work is as follows: Plug and abandon the original perforations. Pull the existing 3-1/2" 9.2# N-80 PC tubing completion. Mill a section in the 7-5/8" casing and lay a cement plug below and across the section. Kick-off and drill a new 6-3/4" hole to TD of 150' MD below the prognosed top of Sadlerochit Base and 900' departure from the current wellbore. Install a 5-1/2" 17# 13CR liner. Run cased hole logs. Perforate with casing guns. Recomplete with 3-1/2" 13CR tubing. CURRENT STATUS: Well 18-9 is currently shut-in due to high GOR. 18-9 is a graben well drilled by Nabors 26E in April, 1986 and completed by Pool 102 in August, 1986. The well was worked over in January of 1987 because it would not flow, and it was believed the Van guns used to perforate had not fired. Finding the guns had in fact fired, the tubing was re-run and the well received it's first mud acid stimulation. Production after the stimulation went immediately to high GOR and the gas mechanism was identified as a channel up later that year. To date, 18-9 has undergone one other pre squeeze mud acid stimulations and three cement squeezes (October '87; 40+ bbls behind pipe, January '89; 64 bbls behind pipe, and September '91; 104 bbls behind pipe) to shut off channels both up and down. The down channel is suspected of communicating with a fault mapped less than 50' away on the top of the Wahoo. As a result of the fault proximity, over 200 bbls of cement have been pumped into the well and a squeeze pressures above 1300 psi cannot be maintained. Currently, after the well's last failed squeeze, it is not being produced and is able to maintain a 5 bpm injection rate at 2400 psi. We suspect the current condition of the casing below the production packer and the entire 3- 1/2" tubing string to both be fairly good, as the well has produced very little fluid and no water during it's life time. ,. PERMITTING: The attached sundry notice covers the plugback of the original well and the drilling permit covers the proposed drilling program.
