Coiled tubing (CT) has been used at Prudhoe Bay since the early 1980’s, saving hundreds of millions of dollars in well servicing costs for such operations as cement squeezing, well cleanouts, stimulation, inflatable packers and plug placements, fishing, and temporary artificial lift applications previously performed by drilling/workover rigs. The majority of these CT jobs are currently conducted with 1-3/4″ OD CT which has proven to have excellent strength, capacity, and durability for typical field operations. With the recent availability of 2.0″, 2-3/8″, 2-7/8″ and 3-1/2″ OD CT, additional drilling and production applications once thought improbable to impossible have been achieved.
