Remarks: State of Alaska Memorandum To: The Commissioners December 29, 1995 From: Wendy Mahan IIIIf\ Subject: Kuparuk LSEOR Tie-in Flaring Tom Wellman, Kuparuk Staff Manager, asked the Commission for guidance on allowable flaring during their LSEOR tie-in work. After internal discussion at the Commission, the decision was made to allow up to 48 hours flaring for facility upgrades, as long as measures were taken to reduce the amount flared when possible by shutting in high GOR wells. I called and gave Bill Masino, Kuparuk Production Supervisor, this advise verbally. Mr. Wellman's estimate of flared volume was 120,000 mmscffor the upgrades, which would center around a TAPS slowdown 09/11-12/95. The facility upgrades at CPF2 required flaring by both CPF2 and CPF3. 103,149 mmscfwere flared at these facilities due to the upgrades. High GOR wells were shut-in as well during this time to reduce the volume of gas flared. CPF1 also reported flaring associated with tie-in work from 10/26-10/29/95. Total volume flared was 28,128 mcf. The work encompassed tie-ins of a new transformer for 3 modules, installing a new switch gear and MCC's. They had to also tie-in new wiring in support of these items. The transformer also supplies power to the STY compressors. Circuits had to be de-energized to safely complete the work and this required shutting down the STY compressors. Crews worked around the clock on the equipment upgrades, but it did take longer than expected. Since the STY compressors take suction from many low pressure sources, production rates would have to be significantly reduced to have any impact on the flaring. Typically, nothing is done to minimize flaring associated with a STY compressor for this reason. Although the CPF 1 tie-in work took longer than the approved time frame, I recommend that it also be approved. ~. <..Y ~. v"^ 1vd~ ~ ~ $L- -ru 1) t..-:> ) S--D ,.J »U~ to' State of Alaska Memorandum To: The Commissioners December 29, 1995 From: Wendy Mahan WM Subject: Kuparuk LSEOR Tie-in Flaring Tom Wellman, Kuparuk Staff Manager, asked the Commission for guidance on allowable flaring during their LSEOR tie-in work.

FrOIU Lindsey Clurk SID Scope: Tîc~ìn new tnmsformcr for modules CROl, GC81 and GC83, install new switch gear and MCC's. Tie-in new wiring in support of these ìtøjm;, (this is the san1e transformer that suppHes power to the STY compressorR) All of this was required in support of the LSEOR e"Xpansion, Construction crew s were scheduled to work two" twelve hour shifts per day to minimize downtime and optimize installatíon. Although crews worked this schedule unti) completion, the work took longer than originally anticipated. The STY compressors are electrical driven and receive power tì'om some of the common items that were being upgmded above, Circuits needed lO be dc-energized 10 safely complete the work. Therefore no power was available for the STY's. Because the STY Compressors take suction from multiple low prcs¡;¡ure sources and the reduction of overall oil rate or well count does not havc a direct correlation on STY gas to be compressed there was no reduction in production rnte.

A description of the event follows: Electrical upgrades will be initiated on the Central Production Facilìty (CPF) #1 at Kuparuk starting October 23, 1995, and last approximately 3 days. These upgrades consist of removing an existing transformer and instaJling a larger transformer and new switchgear to allow implementation of the Large Scale Enhanced Oil Recovery (LSEOR) project. Installing the new transformer will require a complete electrical shutdown of the CPF-1 NGL Plant and the Stock Tank Vapor (STV) Compressors. The STV compressors take the low pressure sources of gas from the facility and compress them so they can enter the gas lift compression system. With the STY Compressors down, their normal gas throughput must be flared. This means CPF-1 will be flaring approximately 6 MMSCFPD for the entire length 01 the shutdown. A plan has been developed to ensure the time that the STY compressors are down ìs minimized, and therefore flare volumes are also kept to a minimum. Flaring impacts due to the NGL plant being out of service should be minimal. Should you have any questions, please contact our Field Environmental group at (907) 659·7242.

The valve was repaired by instrument techs. I asked about the length of time involved and he was checking into it to see why it took so 10ng.I spoke to him again on 6/26 and he said that the valve was extremely hot and they had to wait for it to cool down before they could start working on it. During that time they did nothing to reduce flaring. 500 mcf flared. 02/03-07/95 Injection gas precooler tub leak. The tube bundle on the precooler tub is outside, up on top of the plant, about 5' in the air. They are aerial coolers. The bundle consists of about 30 1" pipes. One in the middle had a crack and there was a crack on the tube bundle frame, too. They talked to Blair Wondzell about waiting and fixing it all at the same time. He said to keep the commission informed about the situation. The temperature was about -35 deg. F. 02/09/95 Accidental gas release They had no record of this event and he was calling the environmental group to get specifics on it. 02/27/95 NGL plant SID for small scale EOR plant tie-in EOR is enhanced oil recovery. This is a new building and had to be tied into the existing piping. Lines had to be depressured and blocked off. The volume flared was the depressurization volume. 02/28/95 Liquid outlet of STY scrubber restricted, causing STY compressor SID The heating coil malfunctioned, causing the fluid temperature to drop. Ice built up and blocked the line. This caused a high liquid level condition which in turn caused the STY compressors to shut down. The blockage had to be removed and this took most of the day. Nothing was done to minimize flaring because they were using the gas stream to help thaw out the line. He said this type of occurrence is extremely rare. e e ·- ALASKA OIL AND GAS CONSERVATION COMMISSION FACILITY REPORT OF PRODUCED GAS DISPOSITION Facility Central Processing Facility #1 Operator ARCO ALASKA INC Field(s) KUPARUK RIVER UNIT MonthlY ear of Disposition Jan~95 1.

I spoke to Lindsey Clark on June 16, 1995 about the following event that was reported for January: CPF 1 01/14/95 "C" Gas lift compressor tripped off line due to instrument malfunction The operator was going to check the readings on the compressor. This is done about 8 times per day. This gas lift compressor handles about 1/3 of the gas going through the plant. The compressor failed as he went to adjust the selector switch on the control panel. As a consequence an inlet valve to the plant (1002 valve) closed. They shut wells in and troubleshooted the compressor until they got it going again. Then they had to bring the production back up. The root cause of the problem was found on the 20th, when the compressor failed again, although less than an hour this time. Over time a biuldup of really fine metal shavings had taken place ITom switching stations on the control panel and the quantity was sufficient enough to conduct between the metal contacts on the thermocouple. These selector switches were put in when the plant was built and have probably been moved thousands of times by now.
