Impact

The shortened duration of the TAR has added approximately 1 million barrels of oil equivalent to Clair’s production and the production efficiency challenges addressed in the work scope of the TAR plan have so far resulted in the longest run time without a full production shutdown since 2012.

Description of Best Practice

In the summer of 2015, the Clair Joint Venture team undertook a TAR of the Clair Field to address a number of maintenance and production efficiency improvements. With an expected duration of 108 days, a collaborative approach saw this substantially reduced and the TAR safely and successfully completed in 58 days.

The successful delivery of the reduced duration TAR was achieved through:

  1. A drive to achieve superior results by identifying that opportunities to optimise the scope, efficiency and duration of the TAR
  2. A series of meetings and workshops to promote collaboration and focus on detailed reviews of the TAR plan
  3. An ability to leverage and build on Best  Practices and key Lessons Learned from Joint Venture subject matter experts experienced in TAR planning and execution
  4. A collective approach to supporting the Operator in the delivery of the optimised plan with excellence

With a robust TAR plan and an agile Joint Venture Team, the group were react effectively and efficiency to any emerging workscopes to ensure delivery ahead of schedule.
