Abstract: A method of perforating a subterranean formation penetrated by a bore hole and having a multiplicity of strata including a hydrocarbon bearing target strata, with the strata oriented with the dip of the strata running in a first direction. The method generally includes positioning a perforation gun in the well bore adjacent to the hydrocarbon bearing target strata. Next includes orienting the perforating guns so that it will perforate the target strata in a direction perpendicular to the first direction. The method finally includes perforating the target strata. A method of hydraulically fracturing the above described subterranean formation would further include pumping a fluid under pressure into the so formed perforations.

Abstract: A switch panel for use in dispensing equipment which includes a switch plate having a plurality of switch positions with each having an area for receiving and mounting a first electrical switch component thereat, and at least one switch activating selector button having a second electrical switch component fixed thereto. Mounting means are provided for pivotally mounting a selector button at each selected switch position by pressing mounting ears on the selector button through appropriate slots in the switch plate until openings in the selector button are engaged by pivot pins in the switch plate, all without using any tools or connecting elements.
