The Alaska Oil and Gas Conservation Commission ("Commission ") received your letter on December 12. 2007. In addition to the rebuild of the VRU at Granite Point Platform, your letter also advises of efforts underway and planned by Chevron to address similar reliability concerns with the VRU's on Anna and Bruce platforms. The Commission anticipates the completed work will have a positive impact on these platforms' gas handling systems. Chevron is encouraged to continue evaluating projects that will extend the equipment's life. The Commission recognizes Chevron's decision to maintain replacement parts as positive mitigation for past failures that have resulted in long term flaring of elevated gas volumes. We appreciate Chevron's attention to this matter and request Chevron communicate with the Commission as work is comp) ed on Anna and Bruce platform VRU- related equipment.

Regg Petroleum Inspections Supervisor Alaska Oil and Gas Conservation Commission 333 W. 7 Avenue, Suite 100 Anchorage, Alaska 99501 -3539 Response to June 15 2007 Letter from Commissioner John Norman with update on Granite Point Platform VRU reliability issues. Dear Mr. Regg: This letter is in response to Commissioner Norman's letter dated June 15 2007. Mr. Norman requested the feasibility of updating the VRU on the Granite Point Platform, or alternatively to identify other actions that can be taken to ensure the reliability of this VRU. On 8/18/06 the rebuilt VRU on GPP was put back into service and we have not had any un- planned downtime on this unit since then. We have had a couple of planned Platform shutdowns during this time period, so these flare volumes are un- related to the VRU compressor skid. At this present time the VRU on the Granite Point Platform is performing well. As a future project we are looking at installing a variable speed drive on this skid to try and match the RPM's with what the gas demand requires. This will prevent recycle gas from potentially overheating this compressor and it should extend the runtime of this equipment. Our inspection of this equipment indicates that it is now in good shape and there is no need to replace it. We plan to keep in stock the required replacement spare parts. Also, on the Anna Platform, we are currently installing a new VRU skid along with a new gas compressor. This is a significant project and should much improve the reliability of the gas gathering system on that platform. In 2008 we will be doing a similar project on the Bruce Platform. In conclusion, we are always working towards the reduction of our flared gas and should you have any more questions regarding these matters please feel free to contact me at (907) 263 -7654 Sinter Chris S.

Dear Mr. Regg: Christopher S. Myers Operations Supenntendent Union Oil Company of California 909 West 9 Avenue Anchorage, Alaska 99501 Telephone: 907.263.7654 myerscochevron.com RECEIVED OCT 1 3 ZOOb .Alaska Oil & Gas Cons. Commission Anchorage We respond to your September 22, 2006, letter requesting additional information on the flare volumes on the Granite Point Platform (GPP) between February 2, 2006, until August 18, 2006. The increase in flare volumes was associated with safety issues identified on the facility. The time lines and details for the identification and resolution of these issues are as follows: February 2, 2006 through Nlay, 2006 We shut in the GPP Vapor Recovery Unit (VRU) when we identified high oxygen concentrations in the gas lift gas system. Upon investigation, we found that there was a restriction in the blanket gas piping to the crude oil tank. The restriction limited the available suction gas for the VRU thus creating a pressure differential that allowed oxygen to work its way into the gas lift system creating a potentially explosive mixture of gas and oxygen. We also identified the oxygen rich gas as a potential explanation for some recent corrosion- related tubular failures in the GPP wells. As part of our Management Of Change (MOC) process, our field personnel submitted a Field Change Request (FCR) to eliminate the restriction. They shut down the VRU pending implementation of the FCR. The project experienced some delays due to work over activity and a piping tie -in that required a full platform shutdown. June 2006 Upon completion of the work, we made an attempt to restart the system. The new piping modifications created several shutdown and control problems thus requiring additional system modifications. We initiated a second FCR to correct these issues. James B. Regg Alaska Oil & Gas Conservation Commission October 13, 2006 Page 2 July 2006 After implementation of the changes in the second FCR, on July 12 we brought the VRU back on line. The unit ran until July 20, when a bearing failed on the on the electric motor on the VRU. We sent the unit in for repairs. The repair required parts for the pump which had to be ordered. August 2006 The parts for the motor were received and the unit was repaired and shipped back out to the platform. We restarted the VRU on August 18 and it has been running ever since. In addition to the VRU safety issue, we have experienced a few platform shutdowns for preventative maintenance and integrity management issues during the same time frame. These events contributed to the increase in flare volumes. If a more detailed day by day breakdown is needed, it can be provided upon request. The time taken to identify and rectify the VRU issues may appear to be excessive at first glance. But I assure you that Chevron has no interests in flaring excess gas as we have both field operations and sales which depend upon the gas. Nevertheless, our first priority was (and remains) to ensure that our platform systems are operating safely and efficiently. The work flow process to identify the problem(s) and to develop a solution takes careful thought and planning in order to avoid the introduction of additional risks into the system. You also requested information on what we are doing to reduce flare volumes in our operations. We have replaced several of our VRU compressors on other platforms with newer models and we have installed a new type of gas lift valve (a "nova" valve) in several of our troublesome wells. With this work and other system modifications, we have reduced our inlet -wide daily average flare volume over 1000 mcfd (from a daily average of 3300 mcfd in January to 2130 mcfd in August), a reduction of over 35 %. Should you have anymore questions regarding these matters please feel free to contact me at (907) 263 -7654. Sincerely, GAw, 6% . Chris S.

June, July and August 2006 Gas Disposition Reports (Facility Report of Produced Gas Disposition, Form 10 -422) for the Granite Point Platform (Granite Point Field). Preliminary indications are that the gas flared or vented greater than I hour during these 6 months should be classified as waste. Unocal indicates Flaring at Granite Point Platform during these months was attributed to the shut down of the vapor recovery unit ( "VRU "). Flaring related to the VRU shutdown began March 7 and continued at least through August 31, 2006 according to the monthly gas disposition reports received by the Commission. The volume of gas flared greater than I hour during this time was reported as 15,065 Mcf; there is insufficient information to determine if flared volumes reported as less than or equal to 1 hour duration during this timeframe are also attributable to the VRU shut down. Supplemental information provided with the gas disposition reports indicate troubleshooting, maintenance and waiting for parts to be manufactured as reasons for the lengthy flare. Before the Commission assigns a waste determination, Unocal is asked to provide any information it believes affects the flaring authorization decision. Included should be what is being done by Unocal to prevent recurrence of this failure (and the duration of the failure) for the Granite Point Platform VRU, and the timeframe for restart of the VRU. The Commission is also interested in the identification of other equipment susceptible to similar failure in Unocal- operated fields, and how Unocal intends to address the potential for failure from a preventative standpoint. Information must be received no later than October 13, 2006.

The Commission is satisfied by the explanation provided in the October 13, 2006 letter that Chevron has taken prudent steps to ensure no additional risks have been introduced into the safe operation of the VRU on this platform as a result of the repairs The Commission has based its authorization (flaring greater than one (1) hour duration during March through September 2006) on the reports and a review of the additional information provided On or before December 15, 2007, Chevron is requested to report to the Commission concerning the feasibility of up- dating the VRU on the Granite Point Platform. or alternatively to identify other actions that can be taken w ensure the reliability of the VRU.
