Impact

The focus on improving the collaborative approach had a major impact on the long term sustainability of both the Erskine and Lomond assets. The short term impact has been the delivery of a number of key milestones and significant achievements that have added real value to the business, including:

  • All five Erskine wells online for the first time in two years;
  • Erskine daily production rate is the highest it’s been in two years (approximately 27,000 barrels of oil equivalent per day);
  • Erskine production efficiency is currently above 90% (highest since 2012); and
  • Combined production from Erskine and Lomond is the highest it’s been since changing to a single train operation.

 

Description of Best Practice

In September 2014, Chevron Upstream Europe (CUE) created a new Erskine Asset team. At the same time, BG Group were about to embark on a large scale six month floatel maintenance campaign and associated turnaround (TAR) on their Lomond facility, which remotely controls CUE’s normally unattended Erskine  installation and processes and exports the field’s hydrocarbons.

With new employees (both Chevron and BG Group) came new ideas and opportunities to improve collaboration were quickly identified. The teams started small, with regular meetings to address ways in which collective action could enhance operations.

These meetings became a foundation on which to build and the two parties quickly decided that greater collaboration was key to performance improvement and sustainability. Both groups began working together through key TAR meetings, morning calls, flow assurance work groups, engineering studies and management engagements.
An example of where this new approach has added real value to the business is the safe and successful completion of the recent large-scale maintenance campaign at Erskine.

A key element of the campaign involved a practice called ‘pigging’, which used devices known as ‘pigs’ to perform various maintenance operations, including cleaning and inspection, on the 30 kilometre pipeline that ties Erskine back to BG’s Lomond platform. The campaign involved running a total of 14 pigs, including an intelligent pig, which was essential for proving the long term integrity of the pipeline – a significant achievement considering the last pigging campaign took place in 2009.
Having created a joint vision and developed a trusting, accountable, fit-for-purpose and collaborative relationship, the three-month campaign was executed on schedule. A testament to the efforts of all onshore and offshore personnel involved and the commitment shown to planning, peer reviews, offshore representation and daily progress meetings.
