I know I have not seen it myself. Pretty shallow leak and small at that. According to the protocol that Joe and I have collaborated on, this is classified as slow T x IA communication. The requirements for such a well are, --addition to the monthly monitoring report --annual MITIA/LLRT --CMIT Tx IA every 4 years --resubmit sundry if well conditions change On the basis of the information you have provided, it is appropriate to return the well to water injection service. By copy of this email, you have approval to proceed. We will process the sundry on receipt.

The Drill Site Operator reported high IA pressure and an MITIA was conducted to evaluate the pressure source. A LLR of .3 bpm @ 3000 psi established. Recent events: > 02/07/02' MITIA Failed, .3 bpm @ 3000 psi. > 03/11/02' Set PXN plug > 03/13/02' CMIT Failed LLRT .7 bpm @ 2500 psi > 04/19/02' SL re-set TTP .. ., > 04/21/02' CMIT TxlA Passed to 3000 psi > 05/02/02: LDL Complete. ID'd single leak @ 445'. This sundry request is to allow for continued injection of water. The following supports the request: - A CMIT-TxlA Passed on 04/21/01 to 3000 psi against a tubing plug, demonstrating competent production casing. - Pressures and injection rates will be monitored and recorded daily and checked for indications of a production casing leak. - A CMIT TxlA against a TTP will be conducted every 2 years to confirm production casing integrity. Proposed Action Plan 1. Allow well to continue water-only injection. 2. Record wellhead pressures and injection rates daily. 3. Submit a monthly report of daily pressures and injection rate. 4. Perform combination MIT Tubing x IA against a plug every 2 years. 5. Stop injection and notify the AOGCC if there is any indication of loss of production casing integrity.

On 02/07/02, an MITIA conducted on NK-65 failed. A leak rate of 13 GPM @ 3000 psi was established. The well is currently injecting 1200 BWPD @ 2200 psi. Our plan is to set a TTP, conduct a CMIT TxlA, then a leak detect log. We are planning to leave the well on injection until the TTP is set. This work has been given a high priority and should happen in the next month. We will inform you of the results of the testing. Please call if you have any questions or would like to pursue some other evaluation plan. Thanks for the help! Joe ..... Original Message .....

Does 10 minute buildup qualify as rapid communication?? You have approval to keep the well in injection service pending your diagnostics. Please add it to the monitoring list and keep us advised on the determinations. I suspect you should have a game plan by the end of February. Bob, please make an entry into the database regarding this MIT failure. If anybody has any questions, please give a call.

Cost: $120M Cost Code: F58NIE Niakuk water injection was recently converted from seawater to produced water. In doing so, the rate in which NK-65 was injecting has significantly decreased. According to reservoir pressure trending, NK-65 has never injected enough water to support the surrounding area. Fortunately, NK-65 was originally perfed in the toe of the well, which is horizontal, to maximize total sweep capabilities of this injector. There is approximately 170' of unperfed Kuparuk sand further up the wellbore. We would like to perf this entire zone to improve injection rates of NK- 65 and increase its support to NK-62. Please perforate the following interval in NK-65 (injector) with a 2-7/8" power jet charges, 6 spf, 60 degree phasing and random orientation. We do not want the well killed, so please plan on lubricating the guns. Please refer to the attached Anadrill CDR/IMP for location of added perfs.

Real-time inclination and azimuth readings were monitored during kickoff and sliding intervals throughout the well. Continuous inclination at the bit was provided with the IAB tool from 12800' to 12938'. The final survey point was at 12876.3' with an inclination of 73.04 degrees and an azimuth of 2.3 degrees. This survey was projected to TD, giving the final bottom hole location: Measured Depth: 12938' Tree Vertical Depth: 9310.69' Latitude: 7062.35 N Departure: 3446.08 E Displacement at Azimuth: 7858.26' at 26.01 deg FORMATION EVALUATION Real-time GR was used for lithology identification; specifically, to pick casing points for the surface and intermediate hole sections. M10 GR, CDR, and Impulse (with IAB) tools were used at different times over the entire well. Real-time logs, DLIS files and ASCII data were faxed/mailed in a timely manner, and the dumped memory data was provided within hours after the tool was above the rotary ruble. DRILLING MECHANICS DWOB and DTOR were provided from surface casing down. The downhole measurements were monitored by the driller on the rig floor, as well as the Anadrill engineer on location. DTOR was used to spot locking cones and bit condition. Annular Pressure While Drilling (APWD) was used from 6252' to 12800', with the final logs provided complete with surface data. SHOCK Shock is monitored in the MWD, CDR, and IAB tools. It remained low most of the well, with the exception of a 40' section around the depth 12800'. This was the transition from the HRZ to the Kupamk. RPM and flow was adjusted to lessen the shock for the MWD and BHA. WASHOUT DETECTION Washouts can be seen from MWD turbine rpm, pump pressure, and flow. There were no washouts. LESSONS LEARNED Expect and monitor shocks when drilling from the HRZ to Kuparuk zones.

The well was planned to be a horizontal producer with TD at ASP X=725,000 Y=5,988,500. Due to the small amount of pay, the well penetrated the Kingak Shale while making the build to horizontal. The decision was made to continue drilling Kingak until crossing a known down thrown fault and coming back into Kuparuk. The drilling was accomplished without difficulty. However after making a MAD pass, the Kingak began to heavily pack off resulting in an inability to get back to bottom. Since we were not able to get back to bottom we decided to just case off the upper section of Kuparuk. We then ran the liner to as deep as possible at 13,840'. Therefore this is the new TD of the well, ASP X=725,191.63 Y=5,987,937.78. The Kuparuk section found in this cased portion of the well did not meet economic requirements for a Niakuk Producer. Therefore a USIT bond log was run and the well was prepared to be an injector. Therefore the differences from the original well plan are: 1. A change in BHL to X=725,191.63 Y=5,987,937.78. 2. A change in well status from producer to injector. SSD Contact: Scott Goldberg Niakuk Drilling Engineer (907) 564-5521 BP EXPLORATION BP Exploration (Alaska) Inc. 900 East Benson Boulevard P.O.
