Abstract: A compact setting tool that sets a packer or bridge plug in a wellbore and then self bleeds the gas pressure prior to pulling the string out of the wellbore.

Abstract: A method and apparatus for using a plurality of impact dampening discs composed of a closed cell polyurethane foam composite with polyborodimethylsiloxane as a dilatant non-Newtonian fluid dispersed through a foam matrix in a downhole setting tool to absorb the energy released during setting operations.

Abstract: A gun to gun transfer delay fuse that includes a delay housing, a first cylindrical cavity housing a firing pin and igniter, and a second cylindrical cavity housing a delay fuse with a centralizer feature.

Abstract: A mechanical gun to gun delay for providing a desired time delay between the firing of a first gun and the firing of a second gun downhole without using a pyrotechnic fuse as the delay.

Abstract: A setting tool comprising a first and a second cylindrical body with inner bores, a third cylindrical body engaged to the first cylindrical body and having an inner cavity with an axial opening adapted to accept a power charge and a having a distal end with a shoulder engaged with the second cylindrical body, a fourth cylindrical body coupled to the third cylindrical body and having a transverse slot, a fifth cylindrical body fixed to the second cylindrical body and having an inner bore wherein the fourth cylindrical body is engaged therewith and further having a radial face within the second cylindrical body, a disc shaped impact dampening material with a hollow center having the fourth cylindrical body is located there through and coupled to the radial face of the fifth cylindrical body, and a sixth cylindrical body coupled to the fifth cylindrical body and having a transverse slot.

Abstract: A setting tool for use in setting bridge plugs comprising a piston rod using an improved fastener design to the lower piston to prevent warping of the piston rod when setting.

Abstract: A well completion method and apparatus comprises a pipe string having a bottom attached boring bit and scraper. Above the bit at designated well fluid production locations, perforation assemblies are integrated into the pipe string. Each perforation assembly comprises a by-pass circulation mandrel and a perforation gun. The circulation mandrel is secured at opposite distal ends in threaded Y-adapter boxes. The perforating gun is secured in collar bores respective to the opposite end Y-adapters.

Abstract: A well completion method and apparatus comprises a pipe string having a bottom attached boring bit and scraper or reamer. Above the bit at designated well fluid production locations, perforation assemblies are integrated into the pipe string. Each perforation assembly comprises a by-pass circulation mandrel and a perforation gun. The circulation mandrel and perforation gun are both secured to respective arms of a Y-adapter. The Y-adapter leg receives the pin end of a traditional drill or production pipe. In one downhole trip, the wellbore casing may be scraped and the bottom-hole cement plug drilled out. Without removing the pipe string, the wellbore is flushed by a circulation of clean fluid down the pipe string bore, through the circulation mandrels and out the bit tooth cleaning jets into the wellbore annulus. Subsequently, the wellbore pressure is raised to detonate casing perforating shaped charges in the perforating gun.
