Patent Number Title Of Patent Date Issued
6505559 Well bore cutting and perforating devices and methods of manufacture January 14, 2003
A tubing and casing cutter is shown which can be assembled in the field from a plurality of pressed segmented pellets of free standing explosive material. The segmented pellets have a liner glued to at least one exposed face thereof. The pellets are glued to a backup plate with two mirro
6354219 Shaped-charge liner March 12, 2002
A liner for a explosive shaped charge, such as those used in perforating operations in oil and gas wells, is formed from a powdered metal mixture that includes molybdenum. The molybdenum allows a higher density liner to be formed to create denser jets for achieving deeper penetration, bu
6220370 Circulating gun system April 24, 2001
A tubing conveyed perforating apparatus is shown which includes a tubular firing section which carries a plurality of explosive charges. The explosive charges are initially aligned with regions of reduced wall area provided in a tubular firing section which initially surrounds the ch
6216596 Zinc alloy shaped charge April 17, 2001
A shaped charge is shown with enhanced creep resistance for use in a perforating gun having an elongated spiral strip open to the wellbore through which the charges are attached. The shaped charge is a hollow bodied capsule and hollow bodied cap, both threaded for easy attachment to
6123001 Detonating cord cutter September 26, 2000
A device for cutting a detonating cord having an explosive core is provided. The device includes a detonating cord holding member having a cord holding portion, such as an aperture or recess, configured to closely receive the detonating cord so that the detonating cord is held in place
6062310 Full bore gun system May 16, 2000
A tubing conveyed perforating apparatus is shown which includes a tubular assembly made up of a plurality of tubular sections. A plurality of explosive charges are located within the interior bore of at least two of the tubular sections of the tubular assembly. A firing head is carried o
5829538 Full bore gun system and method November 3, 1998
A tubing conveyed perforating apparatus is shown which includes a tubular assembly made up of a plurality of tubular sections. One or more elongate charge holders are located within the interior bore of the tubular assembly and carry explosive charges thereon. A firing head is carried on
5797464 System for producing high density, extra large well perforations August 25, 1998
A shaped charge and liner having a minimum outside diameter determined by the formula:Where:D.sub.L =Liner Minimum Outside DiameterD.sub.ID =Carrier Inside DiameterThe geometry of the shaped charge reduces the chances of interference between charges by controlling burn time, as does the posi
5785130 High density perforating gun system July 28, 1998
A high density perforating gun having a carrier housing tube and an interior charge holder tube through which are mounted zinc alloy shaped charges in a phased relationship between about 135 and 145 degrees. The 135 to 145 degree phased relationship provides for an 18 shot per foot p
5662178 Wave strip perforating system September 2, 1997
A perforating gun having an elongated mounting strip and a selected wave or non-linear, zig-zag form as seen in a plan view, with an outer surface diameter sized for convenient insertion and removal from a well. The mounting strip has a series of openings spaced in intervals for mounting
5638901 Spiral strip perforating system June 17, 1997
A perforating gun having an elongated, spiral strip with an outer surface, cylindrical about a longitudinal axis, and a diameter sized for convenient entry and removal from a well. The strip has a series of threaded openings spaced in intervals for mounting capsule explosive charges in a
5542480 Perforating gun with retrievable mounting strips August 6, 1996
A longitudinally slotted carrier having one end adapted for mounting on a tubing string, the carrier being nonplanar, with a slotted configuration and interior dimensions to enable capsule charge orientation at selected phases between 0 and 360 degrees. The carrier has a frangible seam t
4817787 Detonatong cord safety transport system April 4, 1989
A system for safely transporting detonating cord that uses a container with a mounting board of insulating material with a walled path through which the cord is threaded. The path has a series of loop regions and adjoining, parallel regions through which the parallel cord is separated wi
