摘要

National Oilwell Varco (NOV) announced the commercial availability of TRUE-TAPER XR, a new coiled tubing (CT) string design optimization that allows shorter taper sections to achieve better results for CT operators working in extended-reach applications, the company said. The TRUE-TAPER XR achieves a linear taper by gradually varying the thickness of the flat steel strip, reducing stress concentrations and bias welds while optimizing safety factors and strength-to-weight ratio. The string design enhancement has more precise string-weight distribution in the lateral, which allows operators to maintain higher performance levels with longer strings while meeting stricter weight requirements. In an early project, a TRUE-TAPER XR string design allowed a customer to reduce the number of tapered sections in its string from four to two; additionally, the total average length of the tapers was reduced by almost 65%. nov.com.
