The Constitution Spar is located in Green Canyon block 680 in the Gulf of Mexico, approximately 190 miles from New Orleans and in approximately 5,100 feet of water. The original nameplate separation capacity for the spar is 70,000 BOPD and 200 MMSCFD and production potential from future developments is expected to exceed this limit. In order to maximize the value to Anadarko and its partners, a systematic effort is underway to enhance the throughput of the facility.
The methodology includes evaluating all components of the subsea and topsides system for potential bottlenecks and identifying actions to remediate them. The overall goal is to utilize existing infrastructure to maximize production volumes with minimal investment into facility upgrades. One of the bottlenecks that was identified was the design capacity of the production separators. Separator designs are typically performed with little information on reservoir fluids and separation correlations do not always match field performance data. There is also very limited information available in the literature about improving separation efficiency in the field. Therefore, field tests were performed with the goals of identifying any deficiencies that would inhibit the facility from reaching nameplate capacity, as well as to identify areas of improvement that would allow the facility to processbeyond this limit.
The test as a whole was successful and the first and second production trains saw capacity increases of 23% and 32% respectively. All the separation Key Performance Indicators (KPIs) that were established prior to the test were met or exceeded due to rigorous management of the process conditions and chemical treatments.
In addition to the test results, the paper will include discussion on pre-planning, safety review, test design and real-time performance tracking, all of which were critical in order to ensure that the test objectives were met with minimal impact to facility uptime. There will also be discussion on specific separation challenges that were faced and actions taken to address them.
