| A carrier tube for use in a wellbore perforating gun has inner and outer layers selected from materials of different, comparative physical properties. The inner layer has a higher compressive strength, and the outer layer has a higher yield strength. The inner layer enables the tube to withstand wellbore compressive pressures, which may, depending upon the material selected, include relatively high pressures, while the outer layer contains any fragments of the inner layer that result upon detonation of the gun. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. | ||||||
| 146 | COMPOUND PERFORATOR WITHOUT BODY | PCT/CN2006002216 | 2006-08-29 | WO2007031001A8 | 2007-07-12 | ZHANG GUOAN; ZHOU ZHIHUA |
| A compound perforator without body includes an igniting head, a detonating cord and a perforating part. The perforating part consists of several serially connected perforating units, and each of the perforating units possesses one bullet clip and one bullet connected to the detonating cord. The bullet clip is made of fragile metal material and has powder column around it. During construction, the detonating cord is detonated with the electric detonator electrically and the bullet is then detonated to complete perforation. The explosion of the detonating cord and the bullet ignites the powder column and the burnt gas reaches its peak pressure in short time to obtain excellent perforating and crack extending effect, while crushing the bullet clip to avoid subsequent damage on the well. | ||||||

| 150 | WELLBORE PLUG ISOLATION SYSTEM AND METHOD | EP15832132 | 2015-05-20 | EP3180493A4 | 2017-08-16 | SNIDER PHILLP M; GEORGE KEVIN R; HARDESTY JOHN T; WROBLICKY MICHAEL D; CLARK NATHAN G; ROLLINS JAMES A; WESSON DAVID S |
| A wellbore plug isolation system and method for positioning plugs to isolate fracture zones in a horizontal, vertical, or deviated wellbore is disclosed. The system/method includes a wellbore casing laterally drilled into a hydrocarbon formation, a wellbore setting tool (WST) that sets a large inner diameter (ID) restriction sleeve member (RSM), and a restriction plug element (RPE). The WST is positioned along with the RSM at a desired wellbore location. After the WST sets and seals the RSM, a conforming seating surface (CSS) is formed in the RSM. The CSS is shaped to engage/receive RPE deployed into the wellbore casing. The engaged/seated RPE isolates heel ward and toe ward fluid communication of the RSM to create a fracture zone. The RPE's are removed or left behind prior to initiating well production without the need for a milling procedure. A large ID RSM diminishes flow constriction during oil production. | ||||||

| A method is for establishment of a new well path from a well. The method comprises disposing and anchoring a plug base in a casing in the well; lowering a perforation tool into the casing; forming holes in the casing along a longitudinal section; pumping a flushing fluid out through outlets in a flushing tool and into the casing and further out into an annulus; pumping a fluidized plugging material out through the flushing tool and into the casing and further out into the annulus; placing the fluidized plugging material along the longitudinal section so as to form a plug across a cross section of the well; wherein the outlets in the flushing tool are angled non-perpendicularly relative to a longitudinal axis of the flushing tool. The method also comprises removing a portion of the plug until a cross-sectional section of the plug remains in the annulus; disposing and anchoring a direction-guiding element in the casing within the longitudinal section; by means of the element, guiding a drilling tool against the inside of the casing; and forming an exit hole through the casing and the cross-sectional section of the plug, thereby allowing a new well path to be formed from the well. | ||||||
