Abstract: In one aspect of the invention, a thermite containing apparatus (160) is run into the wellbore (105) on a wire line and a window is subsequently formed in casing wall. In another aspect of the invention, the apparatus includes a run-in string or drill stem (110) with a drill bit (120) attached to a lower end thereof. A diverter (130), like a whipstock is attached temporarily to the drill bit with a mechanically shearable connection (132). At a lower end of the whipstock, a container (160) is formed and connected thereto. A telescopic joint (200) extends between the bottom of the container and an anchor (280) therebelow. The assembly allow to form a window and drill a lateral in a single trip.

Abstract: The present invention describes a drill pipe in which various sections of the pipe are strengthened, or their shape is altered, in order to improve the wear and buckle resistance of the drill pipe. The sections are strengthened using various hardening methods such as heat treatment processes and/or expansion techniques. A sleeve can also be applied to the strengthened portions. Surface enhancers, such as hardbanding, can be applied to the strengthened portions or the sleeve in order to provide abrasion resistance or to reduce friction.

Abstract: Methods and apparatus for utilizing a downhole deployment valve (DDV) to isolate a pressure in a portion of a bore are disclosed. Any combination of fail safe features may be used with or incorporated into the DDV such as redundant valve members, an upward opening flapper valve or a metering flapper below a sealing valve. In one aspect, a barrier or diverter located in the bore above a valve member of the DDV permits passage through the bore when the valve member is open and actuates when the valve member is closed. Once actuated, the barrier or diverter either stops or diverts any dropped objects prior to the dropped object reaching and potentially damaging the valve member. In another aspect, the tool string tripped in above the DDV includes an acceleration actuated brake that anchors the tool string to a surrounding tubular if the tool string is dropped.

Abstract: The present invention involves a method and apparatus for monitoring conditions downhole and/or manipulating downhole tools by placing electrical wire on a casing string while drilling with casing. Wire is inserted into a groov e within the casing string white drilling with the casing string into a formation. The wi re connects downhole equipment to surface equipment. Multiple casing strings may be drilled into the formation while wire is simultaneously inserted into a groove therein.

Abstract: In one embodiment, a method for drilling a wellbore includes an act of drilling the wellbore by injecting drilling fluid through a tubular string disposed in the wellbore, the tubular string comprising a drill bit disposed on a bottom thereof. The drilling fluid exits the drill bit and carries cuttings from the drill bit. The drilling fluid and cuttings (returns) flow to a surface of the wellbore via an annulus defined by an outer surface of the tubular string and an inner surface of the wellbore. The method further includes an act performed while drilling the wellbore of measuring a first annulus pressure (FAP) using a pressure sensor attached to a casing string hung from a wellhead of the wellbore. The method further includes an act performed while drilling the wellbore of controlling a second annulus pressure (SAP) exerted on a formation exposed to the annulus.
