| 134 | Method and apparatus for overbalanced perforating and fracturing in a borehole | US258115 | 1994-06-10 | US5551344A | 1996-09-03 | Benoit Couet; Luc Petijean; Luis C. Ayestaran |
| An overbalance technique propagates a fracture in a formation to stimulate hydrocarbon production from a wellbore. A liquid column in the wellbore is driven into the formation by a gas generator to propagate the fracture. The gas generator can be compressed gas or propellant which is placed within the wellbore near or in the liquid column. Preferably the gas generator is placed in the wellbore above the production zone. The gas generator can be conveyed via tubing, wireline, or coiled tubing. Typically the liquid is brine, water or oil. The liquid can be a resin to consolidate a weak formation, sand and gel to prop a fracture, or acid to etch a fracture face. The overbalance technique has applications to cased and openhole wellbores. In cased wellbores, the technique can be performed as the casing is perforated or after the casing is perforated. | ||||||

| 140 | Linear explosive charge with constant detonation velocity and synchronous booster charges | US65893 | 1979-08-13 | US4286520A | 1981-09-01 | Dallas R. Davis |
| A linear explosive charge with constant detonation velocity, comprising a plurality of series-coupled explosive units or sticks. All sticks are identical and comprise a tubular member of selected length, with matched couplings. A helix of explosive cord is positioned around the tubular member, with ends inserted through openings into the interior of the tube and out through the couplings. At the top end of the stick a length of elastic tube is inserted, over the projecting cord, into the top coupling. When two sticks are to be coupled, the downward projecting cord of the top stick is inserted into the elastic tube along side the starting end of the cord of the second stick. This stretches the tube, which presses the two cords into intimate cross-detonation condition. Small ring-shaped concentrated explosive units can be inserted into the bottom end of the top stick over the explosive cord, as synchronous booster charges. | ||||||
