ABSTRACT Improved coiled tubing (CT) technology, development of specially-designed hydraulically-actuated service tools, and increased emphasis on cost efficiency have made coiled tubing a viable option for many fishing jobs. Before the emergence of coiled tubing fishing technology, traditional service procedures included use of wireline

Proceedings of SPE/ICoTA Coiled Tubing Conference and Exhibition, 2002
Abstract This paper presents the concept of coiled tubing (CT) with a continuously varying outside diameter (OD) over a substantial portion of its length. Potential applications for variable OD CT (VODCT) are discussed to show why this concept is being considered.

Proceedings of SPE Annual Technical Conference and Exhibition, 1991
Abstract The use of coiled tubing (CT) is increasing rapidly in the oilfield service industry. Large CT sizes are being developed to meet new service requirements. The CT is being pushed closer to its performance limits for many of these services. To avoid CT failures in the field, it is important that these limits are well understood.

Experimental and numerical simulation study on fatigue life of coiled tubing with typical defects
Journal of Petroleum Science and Engineering, 2020: Coiled tubing (CT) technology is widely used in oil and gas development. In operation process, defects are common and accelerate the fatigue failure of CT. Therefore, it is necessary to predict the fatigue life of CT with defects.

Continuously Tapered Coiled Tubing
SPE/ICoTA Coiled Tubing Roundtable, 2001Abstract Coiled Oilfield Tubing (CT) continually finds new markets, and has experienced continued growth in extended reach wells and high-pressure service. One major improvement is in the quality possible at skelp end welds, when continuously tapered strip1 is employed to join strip of the same thickness. In this paper, the following are

Coiled Tubing Conveyed Perforating
Proceedings of SPE Latin America/Caribbean Petroleum Engineering Conference, 1996Abstract Perforating and pipe recovery operations performed with coiled tubing provide logistical and technical advantages in certain situations. Conventional tubing conveyed firing head adapters have been redesigned to be conveyed by this method which is activated by coiled tubing pressure.

Operations that include washing sands or other settled solid particles from wells are at present most commonly executed by means of coiled tubing. Well cleaning requires fluids that will lift the particles and carry them to the surface. In order to execute the operation properly the pump capacity must be estimated to secure the required fluid flow ...

Proceedings of SPE Health, Safety and Environment in Oil and Gas Exploration and Production Conference, 1991
ABSTRACT Safe coiled tubing operations require quality control of the coiled tubing, wellsite safety standards for coiled tubing operations, and the safe deployment of long tool strings in and out of the well. The quality of coiled tubing is monitored by a patent pending real-time inspection device, fatigue cycle tracking, data ...
