Patent ID: 8733438

Claim:
A method of facilitating a downhole operation, comprising: measuring loading at a downhole position in a wellbore during a downhole operation, wherein measuring loading comprises measuring a compressive load, a tensile load, a torque load, and/or a shock load with a sub attached to a bottom hole assembly, the sub having a housing defining a flow passage therethrough for accomodating fluid flow through the sub, a seal structure formed as a pressure compensating piston, and a load cell disposed and sealed in an atmospheric chamber, and wherein the housing and the pressure compensating piston cooperate to isolate the load cell from undesirable loading effects; transmitting load data uphole in real-time via telemetry via an optical fiber deployed along a tubular conveyance; evaluating the load data at a surface control unit; and making a corrective action downhole based on the load data; wherein the pressure compensating piston is not in direct fluid communication with an annulus of the wellbore external to the housing.
