ABERDEEN -- Caledus has deployed its SlimWELL well construction technology in the Middle East.

Prior to deploying SlimWELL, the operator had run an expandable contingency casing string and a conventional liner, but neither had achieved total depth in the well, according to Caledus. The company deployed a SlimWELL liner above the reservoir, allowing the operator to continue drilling.

The SlimWELL well construction system is based on a bottom’s up design of close-tolerance, flush-jointed liners. It slims down the well profile, optimizing pipe size across the zone of interest while maintaining well integrity without restricting flow or intervention ability, the company says.

SlimWELL achieved the desired size of tubular at the reservoir by incorporating two technologies:
• The MaxBORE System, which features a high-strength anchor built into the wall of the hanger, allowing full-bore access for the next string 
• The DiVERTA Shoe, which helps to eliminate surge, swab, and ECD effects during installation and circulating.
