Abstract
Drilling rigs are continually setting new records in measured depth versus true vertical depth ratios, horizontal section lengths, and delivering sophisticated versatile yet often operationally complex completions.
Experience suggests that common well intervention technologies including slick line, electric line, e-line tractors, Coiled Tubing (CT) tractors, pump-down services, and CT and CT enabling technologies may have difficulty fulfilling all the possible intervention needs of the wells that can and are being drilled and completed.
This paper will present an overview of available well intervention technology, outline limitations of each technology, and use numerous case histories from challenging interventions performed in Alaska to support the discussions and conclusions.
