Deep Casing Tools, which has a range of innovative tools designed to land casing and completions at target depth within oil or gas wells, has set a new world record in Saudi Arabia for the longest tool run.  

The turbine powered reaming capability of the Turbocaser Express enabled  the new record of 26,318 ft to be reached successfully.   Without rotating the string, 2250 ft of open hole was reamed over a six- hour period, successfully completing the longest measured depth section where Deep Casing Tools has used the Turbocaser Express, a statement said.

The new record also included running the longest 7” liner (16,750 ft) right to the target depth. This achievement broke the previous record set only months before when another 7” Turbocaser Express reamed through 1800 ft of trouble zone to reach 26,044 ft target depth.  This was one of most challenging and critical jobs which was successfully concluded by an engineering and operational team effort, it said.

“The Turbocaser Express technology was deployed to reduce the operational risk, given the hole geometry and the tight hole conditions, noticed while drilling and pulling out of hole over the final section.  Because the Turbocaser Express reams on demand, the wiper trip was eliminated, and during liner operations the tool was activated when tight hole conditions were encountered from 22,450 ft onwards. This resulted in landing the liner at the exact planned target depth, after which the liner was cemented normally. The next step of drilling straight through the motor has been completed,” it said.

Deep Casing Tools CEO Lance Davis said: “The successful performance of the Turbocaser Express has been rewarded with tool orders over £3 million already delivered to Saudi Arabia.  Discussions are in progress for delivery of multiple tools during 2014, including the 5” Shalerunner for completions.

“Deep Casing Tools’ reaming and unique drill through technology provides significant time and cost savings when compared to conventional methods.  With the new ability to ream while running in, the casing can be run sooner while the hole is in best condition, eliminating wiper trips and open hole exposure.” – TradeArabia News Service
