A large proportion of well operations such as liner running, cementing, fishing, or milling can benefit greatly from real-time downhole data. However, these operations require full through-bore, and generally have no or low fluid flow conditions. Current conventional telemetry systems cannot operate under these constraints, causing complex and often high-risk operations to be carried out while relying on surface measurements to infer downhole conditions since no downhole visibility is available.
LoadSentry tools are inserted directly into the drill string and provide continuous reliable data from downhole, independent of fluid type or flow rate. The system has been proven effective during liner cementing operations for cementing assurance, as well as for monitoring loads during liner hanger setting and running tool release.
Complex milling, fishing and well abandonment operations can also benefit from LoadSentry’s tension measurements at the service tool, by avoiding damage to milling blades and confirming fish or packer engagement. The availability of these measurements offers clear visibility of what is actually happening downhole, greatly reducing costs and risks and improving efficiency.
