An operator in the Russia Caspian region consistently drills and completes some of the longest extended-reach wells in the history of the oilfield. Extended-reach drilling (ERD) is defined by a well in which the horizontal section is greater than the total vertical depth by a 2:1 ratio. Standard ERD wells are notorious for being challenging completions due to the long horizontal sections and high friction. These aspects of ERD wells pose risks to systems relying on control lines. What made this well particularly challenging was the extreme measured depth (MD): 38,047.5 ft (ll 596.9 m). To enable efficient production, the operator needed reliable bottomhole production monitoring and turned to Baker Hughes, an industry leader with best in-class tools, cutting edge technology, and flawless service delivery.
As a solution, Baker Hughes recommended the SureSENS'" permanent downhole monitoring system which supports multiple monitoring devices on a single tubing encapsulated cable (TEC) and interfaces with surface, subsea infrastructures, or floating facilities. Extensive qualification programs and superior metrology specifications offer the capability of delivering highly accurate information for extended periods of time. Gauges feature proprietary and high-resolution quartz crystal design and have numerous configurations providing flexible solutions for applications such as high pressure/high temperature (HP/HT), high-rate gas wells, and subsea environments.
