Abstract: A system and method of hydrostatic testing a pipeline that is not in service, according to which the pipeline is hydrostatically pressurized and a portable remote telemetry unit is temporarily connected to the pipeline for measuring variables corresponding to the hydrostatic pressurization. Data corresponding to the variable measurements is transmitted to a central location and the portable remote telemetry unit is disconnected from the pipeline.

Abstract: A resilient packer that may be mounted on a high pressure hydraulic testing unit to permit the unit to be moved axially through a string of tubular members connected end to end by collars. The tubular members have flat ring-shaped end surfaces that are disposed as pairs within the collars connecting the tubular members. The end surfaces of each of the pairs are longitudinally spaced a substantial distance. The packer is of such structure that a portion thereof is radially compressed into fluid sealing contact with the interior surface of the tubular member in which it is disposed, but which packer will not hang up on one of the end surfaces when it traverses the longitudinal space between a pair thereof as the testing unit is axially moved through the string of tubular members.

Abstract: A hydrostatic tester that may be sequentially disposed in stands of tubular members as they are lowered into an oil well bore in which gas under substantial pressure may develop. During the period when the hydrostatic tester is disposed in a stand of tubular members but not in use, an improvement operatively associated with the hydrostatic tester automatically vents gas from the bore hole to the ambient atmosphere prior to the gas pressure building up in the bore hole to the extent that the hydrostatic tester will be blown from the tubular stand with possible injury to the testing crew.
