Inwell and caissan lifting systems

With more than 70 percent of the Earth’s surface covered by water, it was inevitable for oil and gas fields to eventually be developed in offshore areas around the world. Schlumberger has been involved in pioneering the advanced technologies necessary to produce in challenging subsea environments from the very beginning.

In 1990, REDA, a Schlumberger company, collaborated with several oil and service companies in a joint industry project aimed at understanding and implementing reliable, low-risk subsea lift systems. With a goal of installing and retrieving subsea ESP systems reliably, studies focused on tree designs, power feeding through tubing hangers, workover vessel intervention techniques, and power distribution. The venture led to a series of worldwide, industry-first subsea ESP installations, with Schlumberger playing a leading role in providing the integrated lifting solutions.
