Well intervention insights—Question 4

We have tool planners now that let us model with better accuracy the downhole conditions than ever before. Wireline tension modeling is a critical part of most of operations now but especially on deep, high-flow tortuous wells. Cable technology has been revolutionized where we can intervene in a deeper well. Our new polymer-locked cables reduce friction, meaning higher overpulls and greater reach. They hugely simplify pressure control with no risk of stranded wires and eliminate grease in the environment. They can also have distributed fiber sensing technology embedded. On-demand release technology can leave a clean fish if absolutely necessary, enabling a simpler and more successful fishing outcome. We are also seeing technologies that bridge between conveyances. Digital slickline can do most electric line work now. Electric line tools can do basic coiled tubing operations with no fluids introduced into the well. Coiled tubing can now deliver electric power with distributed fiber sensing, taking it to new levels of capability. For coiled tubing safety, the real-time pipe inspection system ensures pipe reliability with continuous monitoring and tracking of defect evolution throughout the entire coiled tubing service life. All of this can reduce cost and risk.
