The Curtis Blount Outstanding Paper Award winners, Global Tubing / Nine Energy Services will present their winning paper “Overcoming the operational challenges of +13,000-ft well laterals with 2.375-in coiled tubing”at an ICoTA Global Webinar on 5th August 2020.

The abstract from the Paper is as follows:

Well operators continue to push well lateral boundaries from 10,000 ft to 15,000 ft – producing wells with super laterals, which pose challenges for coiled tubing interventions in terms of extended reach. This paper discusses case studies with field results from the Haynesville and Permian Basins, that demonstrate the feasibility of operating in wells with 14,500 ft laterals using highly engineered 2.375-in coiled tubing designs, instead of larger diameter coil tubing or workover rigs. The strings were designed using high strength quench and tempered material, specific wall configurations, and skelp tapers which rapidly transition through four nominal wall thicknesses within a couple of hundred feet. The inclusion of friction reduction tools and chemical additives, along with tailored operating techniques that improve efficiencies were also reviewed and optimized to improve the likelihood of reaching target depths. Further analysis has shown that with future 16,500 ft super laterals where stick pipe was thought to be the only option, interventions with 2.625-in CT are possible with this collaborative design methodology.

The Papers authors are as follows: Irma Galvan, Genesis Mallanao, Garry McClelland and Jessica Perez at Global Tubing. Jason Skufca and Mary Suarez at Nine Energy Service.
