Abstract: The present invention is an improvement in the design of a perforating gun to perforate the casing and rock formations in oil and gas wells. Perforating guns are cylindrical vessels with explosive charges at specified intervals designed to shoot perpendicularly outwardly through the vessel, perforating the casing and into the rock formation. As most wells are generally straight and most formations are relatively flat, the perforations are horizontal in the same direction as the bedding plane of the rock formations. The present invention is to angle the explosive charges so as to cause the perforation to shoot at an angle to horizontal and across the bedding planes of the rock formations. The angled perforations can result in improved completions in stratified reservoirs and fractured reservoirs by contacting all the stratified layers for production and contacting more of the fractures for production.

Abstract: A test fixture for performing in-circuit testing of a printed circuit assembly may comprise a board having a front surface and a back surface. A probe assembly also having a front surface and a back surface is mounted to the board so that the back surface of the probe assembly is adjacent the front surface of the board. The probe assembly includes at least one front surface contact pad positioned on the front surface of the probe assembly that is electrically connected to at least one back surface contact pad positioned on the back surface of the probe assembly. A first board pad positioned on the front surface of the board makes electrical contact with the back surface contact pad on the back surface of the probe assembly. An electrical conductor operatively associated with the board electrically connects the board pad to an input/output pad that is also provided on the board.
