... Abstract The growing demand for maximizing hydrocarbon recovery from challenging reservoirs has a major influence on propelling the coiled tubing (CT) market to provide effective rigless intervention solutions. Among those challenges, the combination of acid stimulation of extremely sour wells...

... pressures (0.25-0.3-psi/ft) Solids Cleanout Considerations and Options One of the most common coiled tubing operations is solids removal. Initially, cleanouts were relatively straightforward and relied on very conservative rules-of-thumb to decide if the operation would be successful. The same rules...

... Abstract With a significant number of exploration and production programs pushing intervention boundaries, 95-ksi grade quenched and tempered (Q&T) coiled tubing (CT) has begun to be utilized in high-profile sour environments. This paper details the development of the newest 95-ksi grade...

... Abstract High strength quenched and tempered coiled tubing (CT) has been developed and commercialized as far back as the 1990s, however in recent years it has grown to be a substantial, if not the main, type of CT in many markets. Testing programs for sour environment compatibility using...

... underbalanced a minimum of 800 ft in each well. To this end, coiled tubing (CT) equipped with fiber optic (FO) and deployment under pressure were implemented, rigless; this was a first in the country. Understanding of zonal contribution in those long intervals early in the life of the wells was key...

... developed that improves the ability of 1.25 in. coiled tubing to clean out the 5.5 in. casing through the 2.375 in. tubing string, thereby eliminating the need to pull and replace the upper completion. A recent application of this new technique in an unconventional well demonstrated that a modified jetting...

... Abstract As coiled tubing grades have evolved over the past 20 years from 70 grade with a minimum yield strength of 483 MPa (70,000 psi) to 140 grade with a minimum yield strength of 965 MPa (140,000 psi) and wall thicknesses have increased, the resulting force required to shear coil has more...

... Abstract A large collection of data recorded during coiled tubing (CT) operations has been analyzed using proprietary pattern recognition algorithms to identify downhole events with a high degree of confidence. These events include the drilling of plugs and stuck pipe incidents. Key performance...
