Paper Number: SPE-173648-MS
..., and case histories in which the wall thickness measurement device was used. Calculating the CT fatigue using the measured wall thickness will increase the accuracy of the CT fatigue profile. This will allow CT service companies to operate at an increased efficiency. Operating companies will also...

... (~ 5 ft) and Universal Tubing Length Monitor (UTLM) accuracy (+/- 1 ft/1,000 ft) and the accuracy of RKB reference. The conventional CT depth accuracy is affected by many factors, including surface CT length measurement accuracy, elastic and plastic CT string elongation, CT buckling, pressure and...

Paper Number: SPE-143348-MS
..., defect depth, width, length, and projected cross-sectional area were developed. The results are within the specified accuracy of the laser scanner. The notch root radius can be estimated by curve fitting the flaw geometry at the root of the notch. The success of obtaining notch root radius depends on...

... prompt detailed data sharing can enable service companies to develop new tools faster and cheaper to satisfy operator needs of tool reliability and accuracy. In July 2007, BP field-tested the impact tool during a memory PLT campaign in an onshore oilfield, UK. The impact tool is a memory gauge that is...

... slides from side to side and the coiled tubing is run in to the well or pulled out of the well. As a result of this exposure, the depth measurement accuracy of traditional coiled tubing counters is compromised. In the shallow gas market of the Western Canadian Sedimentary Basin, the error in depth...

Paper Number: SPE-74833-MS
... Abstract Evolution of coiled tubing services requires greater down-hole depth accuracy. Depth critical jobs include coiled tubing conveyed perforating, zonal isolation and plug setting, among others. Coiled tubing depth measurements are performed at surface, using devices to measure the...

... ± 2-m depth accuracy. The Franklin field required selective perforating of up to 334-m intervals with ± 2-m depth accuracy for the two reservoirs. The second perforating operation was run in a live well. The depth accuracy was needed to avoid perforating high-permeability zones that would cause early...

Paper presented at the SPE/ICoTA North American Coiled Tubing Roundtable, April 1–3, 1997
Paper Number: SPE-38422-MS
.... A reliable measurement system can significantly lower costs and simplify logistics by reducing the need for multiple depth correlation measurements. This paper presents the results of a comprehensive study of the causes of depth errors, and proposes a strategy to improve reliability and accuracy of...
