Field collected data along with surveys for projected well drillouts fed into the iterative string design methodology that produced a record-breaking string profile of 2.625-in outer diameter with over 30,000-ft in length, using custom-fit wall thickness configurations that featured up to 0.276...

... 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...
