HALLIBURTON INSTALLS THE INDUSTRY’S SMALLEST RMLS™ RETRIEVABLE MULTILATERAL SYSTEM WITH FULLBORE CAPABILITIES
DALLAS, Texas - Halliburton Energy Services recently completed the first 5 ½-in. (139.7mm) RMLS™ Retrievable Multilateral System in Canada. The two TAML (Technology Advancement for Multilaterals) level 4 RMLS window installations have the capability to optimize reservoir management, improve productivity and increase reservoir drainage. The smallest in the world, this TAML level 4 system installation offers advanced multilateral (MLT) capabilities to yet another operating environment. Halliburton Energy Services is a business unit of Halliburton Company (NYSE: HAL).
"Economics is one of the primary drivers for installing multilateral wells. Reducing the number of wells required to exploit the reservoir can eliminate a substantial portion of uphole and surface facility
costs for an operator," said Jody Powers, president, Halliburton Energy Services. "With the addition of Halliburton's 5 ½-in. RMLS Retrievable Multilateral System, it is now possible to have multilaterals in even the smallest conventional hole sizes; thereby, greatly expanding upon the potential applications and markets for multilateral systems."
The level 4 junctions, which were installed by Halliburton Energy Services' Sperry-Sun Drilling Services product service line, were created by cementing both the main and lateral wellbores; thus, ensuring full mechanical integrity, hydraulic isolation, and an effective barrier against sand production. Throughout the life of the well, the main or lateral wellbores can be selectively produced or isolated. The RMLS junctions were constructed with a pre-milled window joint containing an aperture of known geometry, and were run as an integral part of the casing string.
For the multilateral wells, a 12 ¼-in. surface hole was drilled and surface casing was set at 141m MD. The 7 7/8-in. mainbore was then drilled to 1,252m MD, at an inclination of 90.1°, where 5 ½-in. production casing was set. The casing string consisted of a slotted liner, an external casing packer, a stage tool, and an RMLS window joint. The window joint incorporated a patented Latch Coupling, which provides precise axial and radial alignment to the aperture while still maintaining fullbore access to the wellbore below. The window joint was set at 82° of inclination and then stage cemented for isolation.
The drilling whipstock was then positioned within the window joint and the lateral was drilled to 1,238m MD and 87.1° of inclination. The lateral liner was run and stage cemented using the external casing packer and stage equipment. A washover operation was then conducted, retrieving the drilling whipstock and lateral remnant, and giving fullbore access to both main and lateral wellbores.
