In early 2019, the client initially planned on running a TRSSSV exercising tool after a Slickline (SL) drift run. Welltec®, having previously provided successful services for this client, was primarily brought to the site as a contingency plan for clean out operations.
The Well Cleaner Wishbone Honer (WBH) had previously been tested for this client, so there was little question about its capabilities. After several technical discussions, the WBH was chosen as the primary option. During rig up, the client added another scope to the job: cleaning the Autonomous Shutdown Valve (ASV) in a single run.
Welltec performed two successful runs using the Well Tractor® and WBH, cleaning the scale from the TRSSSV. After completing the second run, the WBH cleaned the ASV on the way back up hole. After the runs, a 100% SQ inflow test confirmed that the TRSSSV was fully operational.
Running this clean out operation on e-line resulted in several benefits, including reduced operational time due to faster rig up and rig down, less equipment mobilized, and fewer personnel needed to monitor the operation. Welltec’s two successful clean out runs saved the client the trouble of running four other contingency options, resulting in significant time and cost savings.
The client was extremely satisfied with Welltec’s results and, when asked for feedback, stated, “Excellent Job!”
The Well Cleaner Dry Environment (DE) is designed specifically for cleaning in dry environments. The auger at the tip loosens the debris and transports it into the bailer sections of the tool.
Welltec Release Device (WRD®) is a simple tool which adds versatility and risk reduction to the operation. It provides predetermined locations in the toolstring where it can be parted, should it become stuck.
The Well Tractor was regarded as a revolution in the industry when it was introduced in the 1990’s. It enables operators to extend the reach of traditional e-line deployment into highly deviated and horizontal wells.
