The Orlan platform, located off the east coast of Sakhalin Island, Russia, commenced operations on the second stage of Chayvo field development in 2005.

By 2009, all slots on the platform had been utilized. In 2012, following a period of warm stacking, the operator began execution of a drilling campaign involving the recovery and addition of slots, use of multilateral technology to complete dual and tri-lateral wells, and drilling of record-length extended reach wells. This three-part approach to extending platform tility and increasing reservoir access posed a series of unique challenges that required rig upgrades, implementation of new technologies, and close cooperation of cross-functional teams to meet project objectives.

Overcoming the challenges associated with the expansion and upgrade of existing platform infrastructure and the adoption and implementation of various technologies allowed the operator to avoid the significant time and cost of constructing a new platform while effectively extending reservoir access into previously untouched parts of the field. The multi-discplined team’s ability to execute a diverse portfolio of operations contributed tremendously to the success of this ongoing program.

This presentation will describe the planning, execution, and accomplishments of the campaign. Lessons learned and solutions to challenges encountered will also be discussed, including the operator’s use of TAML Level 5 multilateral technology, a novel technique to create a casing exit image with logging-while-drilling tools, and the drilling and completion of the current world-record extended reach well, O-14.
