Deep Casing Tools, the Aberdeen casing and completion technology specialist, report its first order of tools for the challenging Oseberg field in the Norwegian sector of the North Sea. Statoil has ordered 7” Turbocaser Express tools to support the Oseberg East development. The Statoil application follows other international successes with the technology this year.

 

Landing casing and liners in highly deviated wells, altered pressure regimes and frequently unstable formations, can be very challenging, leading to multiple sidetracks and casings set off-depth. The economic impact can be serious, with expenditure overruns and delayed production.

 

Deep Casing Tools’ breakthrough Turbocaser Express delivers a step change in the well construction process. It is a high-speed drillable reaming system that enables casings and intermediate liners to be landed at target depth first time. After normal cementation, the unique internal assembly can be drilled through in minutes in one cost effective operation.

 

The Turbocaser Express is an enabling technology for all wells, to ensure casing is set at the planned depth, a fundamental building block of improved well integrity. The Turbocaser Express has particular application where hole conditions can deteriorate with time and where wiper trips can be eliminated.

 

Manufactured as a single body from high-strength steel, the Turbocaser Express is a rugged and reliable downhole tool that can ream casings through obstructions, is fully high pressure/high temperature compliant and works with any drilling fluid without deterioration in power output, reliability or performance.

 

Lance Davis, CEO Deep Casing Tools said "We are pleased that our unique technology has been selected for use in this important and challenging well. We greatly appreciate the confidence that Statoil has demonstrated by placing this first order with us".
