An apparatus for measuring an internal dimension of a well-bore comprising a tool adapted to be positioned inside the well bore. The tool comprises an optical caliper comprising an optical sensor providing a response correlated to the internal dimension of the well bore, the optical sensor being coupled to an optical fiber.

Apparatus for measuring an internal dimension of a well bore

Fluid diversion measurement systems and methods are described. One system includes a section of tubular having a main flow passage and a fluid diversion port, the section of tubular adapted to be either moving or stationary during a fluid diversion operation, at least two sensors in the section of tubular, at least one sensor located upstream of the fluid diversion port and at least one sensor located downstream of the fluid diversion port, each sensor adapted to measure a parameter of a fluid diverted into a wellbore through the fluid diversion port; and means for using the measured parameters in realtime to monitor, control, or both monitor and control diversion of the fluid. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
