摘要： The present invention discloses and claims methods and apparatus for forming an opening or a window in a downhole tubular for the subsequent formation of a lateral wellbore. In one aspect of the invention, a thermite containing apparatus is run into the wellbore on a wire line and a widow is subsequently formed in casing wall. In another aspect of the invention, the apparatus includes a run-in string or drill stem with a drill bit attached to a lower end thereof. A diverter, like a whipstock is attached temporarily to the drill bit with a mechanically shearable connection. At a lower end of the whipstock, a container is formed and connected thereto. The container is designed to house a predetermined amount of exothermic material at one side thereof adjacent the portion of casing where the window or opening will be formed. A telescopic joint extends between the bottom of the container and an anchor therebelow and the telescopic joint is in an extended position when the apparatus is run into a wellbore. In use, the exothermic material, like thermite is ignited and the window is formed in the casing. The telescopic joint is then caused to move to a second position, locating the whipstock adjacent the newly formed casing window.

摘要： Methods and apparatus enable reliable and improved isolation between two portions of a bore extending through a casing string disposed in a borehole. A downhole deployment valve (DDV) may provide the isolation utilizing a valve member such as a flapper that is disposed in a housing of the DDV and is designed to close against a seat within the housing. The DDV includes an operating mechanism for opening/closing the DDV. In use, pressure in one portion of a well that is in fluid communication with a well surface may be bled off and open at well surface while maintaining pressure in another portion of the casing string beyond the DDV.

摘要： The invention provides an apparatus for actuating a downhole tool by utilizing a pressure differential created by fluid flowing through a conduit. The conduit is in communication with a pressure sensing line that is selectively exposable to areas of the conduit having different pressures. By exposing the pressure sensing line to a portion of the conduit having a predetermined pressure therein, the pressure sensing line causes actuation of a hydraulic tool therebelow.
