When a UK client in the North Sea demanded production logging data from a challenging well, the incumbent service provider was unable to tractor to depth. With the well using an advanced polymer as well fluid, combined with internally lined plastic coated pipe, confidence in the technology was crucial.
Welltec® was initially mobilized as a contingency, but quickly rigged up and delivered where it mattered reaching depth as required.
Based on this impeccable execution, the client had no hesitation in choosing the Well Tractor for the next challenging well in the campaign. This job was a tandem tractor operation through a downhole Y-tool, replacing the incumbent company who had already performed a SIT test three months earlier.
Given Welltec’s achievements on this job, the Well Tractor is now the client’s preferred conveyance method.
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.
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.
