SPE Drilling & Completion, 1993
Summary In the 1980's, a "coiled-tubing revolution" began when coiled-tubing services were expanded to include most workover services. In 1991, this revolution expanded to include openhole drilling with a coiled-tubing unit (CTU) in place of a drilling rig. This paper discusses the design process and the limits associated with the use of

Proceedings of SPE/IADC Drilling Conference, 1994
ABSTRACT The total number of coiled tubing drilling (CTD) jobs worldwide has grown from 4 in 1991 to 11 in 1992 and will probably exceed 25 in 1993. While CTD still represents only a small fraction of the worldwide drilling market, the growth rate indicates CTD is a technology that is rapidly coming of age. This paper summarizes the jobs

Pumping with Coiled Tubing - A New Coiled Tubing Application
SPE/ICoTA Coiled Tubing Roundtable, 2000Abstract Coiled-Tubing (CT) continues to grow as an enabling technology that provides cost economy and time efficiency for the oil and gas industry. It has gained wider acceptance than ever due to efforts of the manufacturers, CT application engineers, and field operators.

A new theoretical model of low cycle fatigue life for coiled tubing under coupling load
, 2021Coiled tubing (CT) technology is widely used in oil and gas industry. In the operation process, low cycle fatigue failure is easy to occur. Therefore it is necessary to predict the fatigue life of CT.

Geosteering and Monitoring Methods for Underbalanced Coiled Tubing Operations in Gas Reservoirs
Day 3 Wed, April 24, 2024Under-Balanced coiled tubing drilling (UBCTD) is one of the techniques used in developing low pressure gas reservoirs. However, a drawback in UBCTD is their limited geosteering and monitoring tools due to the coiled tubing size compatibility and hole ...

Coiled Tubing and Vessel Motions for Riserless Coiled Tubing Systems
SPE/ICoTA Coiled Tubing Conference and Exhibition, 2004Abstract Special care must be taken tomaintain the integrity of the coiled tubing when performing subsea well intervention from a lightvessel without the use of a riser. In these cases the coiled tubingwill act as a riser with respect to withstanding the external loads from waves, current andvessel motions. To avoid local buckling of the

Proceedings of SPE/IADC Drilling Conference, 1996
Abstract Reliable, low cost coiled tubing window milling technology has become the cornerstone of ARCO Alaska's coiled tubing sidetrack program at Prudhoe Bay. ARCO began to investigate coiled tubing drilling technology in 1989. The program grew into an aggressive field application of this technology, with over thirty wells drilled in ...
