Description
Advances in Drilling technology allows construction of wells 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 CT and CT enabling technologies, slick line, electric line, e-line tractors, CT tractors, and pump-down services- cannot fully address all possible intervention needs of the wells that can and are being drilled and completed. Rotary drilling technology and snubbing equipment are often required to service these unconventional and extended reach wells. This talk will present an overview of available well intervention technology, outline limitations of each technology, and use numerous case histories from challenging interventions to support the discussions and conclusions.
