The increased flare volumes at CPF2 in August and September appear to be the result of higher ambient temperatures, slugging, and a few significant events. We have taken steps to minimize the flaring, including shutting in wells. During the warmer ambient months, all three Kuparuk central processing facilities and particularly CPF2 have greater instability with our gas lift compressors (GLCs) based on the lower power output from our gas turbine drivers. Because of the reduced horsepower from the turbine drivers, we are not able to handle and compress as much formation gas from the wells into the plant. The injection lifting gas has to be reduced and this creates more slug flow (gas then liquid slugs) from the wells because we are not lifting them optimally due to less gas handling capacity. The transition time between summer and winter appears to cause the greatest instability due to the balance between horsepower availability and fluctuating ambient temperatures. This year, we have experienced a much longer ambient swing season with temperatures remaining unseasonably warm into November. Sore of the more significant events in August and September were: • Aug 15th - Rapidly rising ambient temperatures reaching nearly 60F caused us to have high discharge pressures which shutdown several of our GLCs resulting in a single day flaring event of over 7 MMscf. During this event the plant shut in more than 4,000 bbls of production to get off the flare and stabilize the plant. • Aug 19th - A power failure, caused by a transformer in the leased water pump module shorting to grotrkl. caused a load shed event in the Kuparuk power net work. CPF2 lost all three injection compressors, and 2 GLCs. This event and the stabilizing of the system over the next 2 days amounted to almost 8 MMscf of gas to flare. During this time, the plant shut in 3,000 bbls of production. • Later half of August - CPF2 brought on line a fourth water injection pump that had not been in operation. This allowed the plant to bring on additional high water cut wells that had been shut in earlier in the summer. Bringing on the large water cut wells created additional slugging and instability in the plant. The plant tried various strategies to stabilize the wells and the process, but the GLCs continued to have problems handling the large slugs coming from the wells. The GLCs continued to trip off line for several days resulting in larger than usual flaring on 8/26th , 8 /28th , and 8/29th. These equipment trips caused flaring over the 4 days of over 18 MMscf. The plant tried various combination of wells shutting in over 4,000 bbls per day of production to reduce flaring and stabilize the process. During the month of September, higher than normal flaring was caused by continuous slugging from our wells and process lines. We continued to try a number of different strategies, including shutting in wells, raising injection lift gas, etc. but we continued to have more flaring than usual, although we were able to keep our process equipment from tripping off line. • Sept 7th - We had a flare event which was caused when we went to reconnect the new transformer (the replacement for the transformer which failed above) back into our power grid, we tripped the "D" GLC off line resulting in another flare event of close to 4 MMscf. • NGLs from Prudhoe were shut off in August and many of CPF2s larger wells in the Tarn satellite area are lifted with miscible injectant (MI). With the use of more lean gas and less MI with the wells, the slugging appeared to increase. The slugging flow regime in our process lines continued through the month of October. Our most problematic issue was trying to determine what wells to shut in and how to stabilize the process lines. A team of engineers has been assembled and are reviewing process data, as well as completing flow modeling on our lines to help to determine the best plan to reduce the slugging flows which are causing the flaring events. This month, we have shut down one of our GLCs and shut in wells. The lower gas injection rates and the shut in wells are resulting in daily production losses of close to 3000 bbls per day, but our flaring has been reduced and I of_ 1 I/7/20069:54 AM Resume to AOGCC CPF -2 Flaring and Pilot Purge Questions our plant has stabilized. Ambient temperatures have also dropped this month, and as the temps continue to drop, we expect to be able to increase injection rates and bring on production Also, engineering personnel continue to work on the issue, and we should have more strategies to help the plant operation in the coming months. No major leaks were found in the purge gas, but, as the number of upsets during the last few months caused equipment shutdowns and flaring, we have had to remain diligent to continuously check that valves, drains and vents have reseated properly. For the most part, the increase in the purge gas is following the volume increase in the safety flare. If you need addition& information or would like to discuss further, please give me a call.

( "CPAI ") concerning the large reported volume of gas flared 1 hour or Tess at the Kuparuk River Unit Central Processing Facility 112. Flaring during August and September 2006 in this category was: August — 47,896 Mc f gas September — 52,844 Mcf gas CPAI Senior Environmental Coordinator Jeff Smith (907 -659- 7242; n1037(aconocophiflips.cnm) responded on November 7, 2006 by email, noting that several events contributing to the significant flared volumes during August and September: 1) 1ligher than normal ambient temperatures, and a longer transition to winter than usual; 2) Power failure; 3) Addition of a water injection pump; 4) Installation of new transformer in power grid; 5) Slugging from wells and process lines as a result of NCL supplies from Prudhoe I3ay (used to snake miscible injectant) being shut down (response to ('BU FS -2 oil transit line failure and 13P decision to shut in entire Prudhoe Ray field). In his email response, it was noted several of these events occurred over multiple days. 1 called hint to ask why the volumes associated with events that occurred over multiple days were not reported as "Flared or vented greater than I hour" on the gas disposition reports. Mr. Smith stated that CPAI records individual incidents of flaring rather than grouping all discrete incidents associated with a triggering event (he did assure me that CPAI dots not cut off flaring simply to avoid the reporting requirements). This is an area not explicitly addressed in our regulations and is interpreted different ways by the different operators and facilities. Specific to CPF -2, there were numerous discrete events triggered by the events noted by Mr. Smith, all less than I hour in duration. Since they did not involve continuous flaring, they were reported according to their time duration as specified in our regulations at 20 AAC 25235(b) -(d). CPAI has a team of engineers assigned to review the process data during August and September to develop strategies that can reduce flared volumes when future plant upsets and ambient conditions force gas flaring. I am satisfied with the additional explanation provided by CPAI and recommend no action be taken on the volume of gas "Hared or vented less than I hour" during August and September 2006. 2 / L u,t4 4 c 1 "L } `l �j� 1 - X'1' lr'L1Xe. 2<i.n t..

Specific to CPF -2, there were numerous discrete events triggered by the events noted by Mr. Smith, all less than I hour in duration. Since they did not involve continuous flaring, they were reported according to their time duration as specified in our regulations at 20 AAC 25.235(b) -(d). CPAI has a team of engineers assigned to review the process data during August and September to develop strategies that can reduce Flared volumes when future plant upsets and ambient conditions force gas flaring. I am satisfied with the additional explanation provided by CPAI and recommend no action be taken on the volume of gas "Flared or vented Tess than 1 hour" during August and September 2006. • ' 2 Amex lus S rn 4 s' 2 c, Csrs b!s RO N 20.

We have taken steps to minimize the flaring, including shutting in wells. During the warmer ambient months, all three Kuparuk central processing facilities and particularly CPF2 have greater instability with our gas lift compressors (GLCs) based on the lower power output from our gas turbine drivers. Because of the reduced horsepower from the turbine drivers, we are not able to handle and compress as much formation gas from the wells into the plant. The injection lifting gas has to be reduced and this creates more slug flow (gas then liquid slugs) from the wells because we are not lifting them optimally due to less gas handling capacity. The transition time between summer and winter appears to cause the greatest instability due to the balance between horsepower availability and fluctuating ambient temperatures. This year, we have experienced a much longer ambient swing season with temperatures remaining unseasonably warm into November. Some of the more significant events in August and September were: * Aug 15th - Rapidly rising ambient temperatures reaching nearly 60F caused us to have high discharge pressures which shutdown several of our GLCs resulting in a single day flaring event of over 7 MMscf. During this event the plant shut in more than 4,000 bbls of production to get off the flare and stabilize the plant. * Aug 19th - A power failure, caused by a transformer in the leased water pump module shorting to ground, caused a load shed event in the Kuparuk power net work. CPF2 lost all three injection compressors, and 2 GLCs. This event and the stabilizing of the system over the next 2 days amounted to almost 8 MMscf of gas to flare. During this time, the plant shut in 3,000 bbls of production. * Later half of August - CPF2 brought on line a fourth water injection pump that had not been in operation. This allowed the plant to bring on additional high water cut wells that had been shut in earlier in the summer. Bringing on the large water cut wells created additional slugging and instability in the plant. The plant tried various strategies to stabilize the wells and the process, but the GLcs continued to have problems handling the large slugs coming from the wells. The GLCs continued to trip off line for several days resulting in larger than usual flaring on 8/26th , 8 /28th , and 8 /29th. These equipment trips caused flaring over the 4 days of over 18 MMscf. The plant tried various combination of wells shutting in over 4,000 bbls per day of production to reduce flaring and stabilize the process. During the month of September, higher than normal flaring was caused by continuous slugging from our wells and process lines. we continued to try a number of different strategies, including shutting in wells, raising injection lift gas, etc. but we continued to have more flaring than usual, although we were able to keep our process equipment from tripping off line. * Sept 7th - we had a flare event which was caused when we went to reconnect the new transformer (the replacement for the transformer which failed above) back into our power grid, we tripped the "D" GLC off line resulting in another flare event of close to 4 MMscf. * NGLS from Prudhoe were shut off in August and many of CPF2s larger wells in the Tarn satellite area are lifted with miscible injectant (MI). with the use of more lean gas and less MI with the wells, the slugging appeared to increase. Page 1 KRU_ PF -2_ Flaring_Pilot- Purge _CPAI_response_2006- 1107.txt The slugging flow regime in our process lines continued through the month of October. Our most problematic issue was trying to determine what wells to shut in and how to stabil ze the process lines. A team of engineers has been assembled and are reviewing pro ess data, as well as completing flow modeling on our lines to help to determine the b st plan to reduce the slugging flows which are causing the flaring events. This month, we have shut down one of our GLCS and shut in wells. The lower gas injection rates and the shut in wells are resulting in daily production losses of close to 3000 bbls per day, but our flaring has been reduced and our plant has stabilized. Ambient temperatures have also dropped this month, and as the temps continue to drop, we expect to be able to increase injection rates and bring on production. Also, engineering personnel continue to work on the issue, and we should have more strategies to help the plant operation in the coming months. No major leaks were found in the purge gas, but, as the number of upsets during the last few months caused equipment shutdowns and flaring, we have had to remain diligent to continuously check that valves, drains and vents have reseated properly. For the most part, the increase in the purge gas is following the volume increase in the safety flare. If you need additional information or would like to discuss further, please give me a call.

As you know, we do not routinely get an explanation of the <1hr events with the gas disposition reports, so I look for trends and significant deviations to trigger questions. The flaring during August and September 2006 are much higher than what we normally see in our data set (data begins 1/2000). volumes flared per month: August - 47,896 Mcf; September - 52,844 Mcf; avg since 1/2000 is 11,475 Mcf. Pilot - Purge: Plot of pilot -purge gas is also included in the attached file. There was a significant increase in pilot -purge gas during August and September; similar situation occurred in 2005 (same timeframe). Is this tied to some particular operations or is there another explanation? Thank you.
