Gerald B McClure is a notable inventor based in Sugarland, TX, who has made significant contributions to the field of subsurface engineering. With a total of seven patents to his name, McClure has developed innovative methods and apparatuses that enhance the efficiency of perforating subsurface earth formations.

Latest Patents

Among his latest patents is a method and apparatus for perforating subsurface earth formations. This perforating system is designed for completing subsurface formations transversed by a borehole. The system includes a sub with a plurality of closed vent ports and a perforating gun that is run into a borehole on the end of a tubing string. To initiate the perforating system, an impact member is dropped through the tubing string. The impact member strikes a percussion firing head, which initiates a detonation wave in a detonator cord. This detonation wave detonates an explosive pellet within the sub, resulting in an explosion that initiates a pressure wave, forcibly opening the vent ports and fluidly communicating the well bore to the tubing annulus. The detonation wave continues along the detonator cord to actuate the perforating gun. Another significant patent is for an automatic separation device for use with wireline conveyed perforating. This method and apparatus automatically separates a wireline conveyed through-tubing perforating gun from a cable assembly. The gun is joined to a hollow sleeve on the cable assembly by a sub closely received in each end, retained by shear members. The force of the explosion upon firing the gun shears the shear members and drives the sub into the sleeve, allowing the gun to drop into the well.
