Abstract (2014 ICoTA Intervention Technology Award Finalist)
Recent advancements in slickline technology improve on conventional jarring operations by use of a digitally controlled jarring tool. The digital jarring tool, operated using the bi-directional communication ability of telemetry enabled, coated slickline, allows the winch operator full control of the timing and force generated on the toolstring. Combining control of the jarring system with the downhole head tension and shock measurements has proven to provide a more effective jarring system and permits the use of slickline in applications not previously considered. Benefits also include reduced training time for proficient slickline winch operations and reduced the exposure to human error when performing well interventions.
The controllable release sub simplifies retrieval of the toolstring when a stuck tool situation is encountered. Upon deciding that tools cannot be recovered using jarring techniques, a command is sent from the surface equipment to the controllable release. The tool separates permitting the retrieval of the top portion of the tools and the wire, while the stuck tools remain downhole. A fishing neck is left behind on top of the stuck tools to simplify fishing operations on subsequent runs. Exposure to risk when performing intervention when using jarring tool and the release sub is significantly reduced and the increased efficiency saves time and decreases costs.
Mr. Loov graduated from the University of Alberta in Edmonton, AB in 1997 and began his career with Lee Tool (a division of Schlumberger) working with slickline, eline and memory logging tools in the field for 6 years before managing operations in different capacities for the next ten years. In August of this year, Rob was transferred from Red Deer Canada to Houston, TX and took his first support role as LIVE Business Development Manager for North America.
