Intervention

Intervention, while a necessary part of a producer's life, is especially challenging for deepwater operations. Reentering deepwater wells is expensive and often time-consuming, and reentry is not always possible given the restrictions of some existing systems and the lack of availability of others. Schlumberger addresses these challenges with cost-effective solutions that help extend the life of the well.

Intervention Systems

• Coiled Tubing Services

  Innovative intervention services conveyed on coiled tubing (CT) are designed to improve your well and reservoir performance. Using either mobile platform-based systems or vessel-based equipment, CT rigless-intervention applications include stimulation, wellbore cleanout, logging, perforating, nitrogen kickoff, sand control, drilling, cementing, well circulation, and mechanical isolation.

• CT TComp
  This coiled tubing total compensation system for offshore protects wellhead integrity during CT operations by limiting wellhead stresses. System rig-up is faster than for conventional systems and requires fewer personnel.

Abandonment

New technologies and techniques ensure the permanent subsurface isolation of deepwater wells. Schlumberger covers key areas, including primary and remedial cementing, evaluation of perforating and cementing operations, and coiled tubing and slickline intervention techniques. Project management of the multiple operations involved helps ensure project success while minimizing costs.

Well-abandonment procedures must meet local standards for long-term environmental protection. The cost-versus-quality equation must be carefully managed to meet the objectives of both operators and regulators.
