A system and technique for pressure testing a line portion, connection, or other linking piece of unknown leak characteristics. The technique includes applying predetermined pressure to the linking piece to be tested as well as to another of known non-leaking characteristics. Thus, a differential ...
Fully implicit procedure of Newton–Raphson iteration was used to solve the non-linear systems of difference equations. Fracture conductivity was updated according to Eqs. (1), (2) for each Newton iteration until convergence was reached. The accuracy of the model developed was tested first, by ...

The steering procedure introduces changes in the main and side lobe structure and in the array beam width and produces a beam-steering effect that makes it possible to direct a narrow main lobe at any desired angle relative to the array's line of extension. If all N elements in the vertica...
A review of literature and reported operating experience on the use of hydrostatic testing to verify pipeline integrity suggests that the test-pressure-to-operating-pressure ratio measures the effectiveness of the test and that in-line inspection is usually preferable to hydrostatic testing. Pressure re...
