Paper presented at the SPE/ICoTA Well Intervention Conference and Exhibition, March 22–25, 2021
Paper Number: SPE-204418-MS
... Abstract A set of 5 wells were to be drilled with directional Coiled Tubing Drilling (CTD) on the North Slope of Alaska. The particular challenges of these wells were the fact that the desired laterals were targeted to be at least 6000ft long, at a shallow depth. Almost twice the length of...
