Abstract: Methods and apparatus for utilizing a downhole deployment valve (DDV) to isolate a pressure in a portion of a bore are disclosed. The DDV system can include fail safe features such as selectively extendable attenuation members for decreasing a falling object's impact, a normally open back-up valve member for actuation upon failure of a primary valve member, or a locking member to lock a valve membe r closed and enable disposal of a shock attenuating material on the valve member. Actuation of the DDV system can be electrically operated and can be self contained to operate automatically downhole without requiring control lines to the surface. Additionally, the actuation of the DDV can be based on a pressure supplied to an annulus.

Abstract: The present invention generally provides a method for remotely controlli ng and/or monitoring at least one parameter of well bore equipment. In one aspect, a method for remotely controlling and/or monitoring at least one parameter of well bore equipment is provided, including: collecting data corresponding to the at least one parameter by a sensor module monitoring the at least one parameter of the we ll bore equipment; transmitting the collected data to a remote control/monitoring un it via a communication link; analyzing the collected data to determine if the paramet er is within predefined limits; if the parameter is not within predefined limits, then transmitting control data from the control/monitoring unit to the well bore equipment for modifying the operation of the well operation equipment so that the parameter will conform to the predefined limits or stopping operation of the wellbore equipment.

Abstract: In one embodiment, a top drive system for drilling with casing is provided with an access tool to retrieve a downhole tool. The top drive system for drillin g with casing comprises a top drive; a top drive adapter for gripping the casing, t he top drive adapter operatively coupled to the top drive; and an access tool coupled to the top drive and adapted for accessing a fluid passage of the top drive system. In another embodiment, a method for retrieving a downhole tool through a tubular couple d to a top drive adapter of a top drive system is provided. The method comprises coupling an access tool to the top drive system, the access tool adapted to provide access to a fluid path in the top drive system and inserting a conveying member into t he fluid path through the access tool.

Abstract: A casing slip joint has been invented that has a first tubular casing member disposed around and releasably connected to a second casing member, the second casing member within and surrounded by the first casing member. Self-destructive shear screws according to the present invention releasably hold the first casing member to the second casing member. In one aspect, a shear screw according to this invention has an outer shear screw with a central recess and an inner member therein. In one aspect the outer shear screw is made of one metal and the inner screw is made of another so that contact by a well fluid sets up a galvanic cell that produces stress corrosion cracking in the outer shear screw that weakens it and/or destroys it. The propagation of such cracks is facilitated by placing one or more notches or recesses in the body of the components.
