Abstract: Apparatus and methods for triggering a downhole tool. The tool string may have an electrical power source and a trigger tool that may be configured for receiving electrical power from the electrical power source and outputting different forms of electrical power each being different from the form of electrical power received from the electrical power source. Each form of electrical power output by the trigger tool may initiate operation of a corresponding one of different electro-mechanical tools connectable within the downhole tool string. A trigger command is transmitted from the surface equipment to the trigger tool to cause the trigger tool to output electrical power having a form corresponding to the electro-mechanical tool connected within the tool string to thereby initiate operation of such electro-mechanical tool.

Abstract: A centralizer operable to connect with and centralize a downhole tool within a tubular string within a wellbore and to facilitate reception of electromagnetic signals transmitted through the Earth. The centralizer has a body, a first contacting member electrically connected to the body and extending radially away from the body such that the first contacting member contacts an inner surface of the tubular string to electrically connect the tubular string to the body, and a second contacting member electrically insulated from the body and extending radially away from the body such that the second contacting member contacts the inner surface of the tubular string to centralize at least a portion of the body within the tubular string.

Abstract: Embodiments presented provide for a built-up, evaluation, shut-in tool that enables real time and pseudo real time control from the surface. In embodiments, an up-link telemetry indicates well data below a configuration valve to the surface. The wellbore data may be used to indicate when true pressure stabilization is achieved during operations.

Abstract: A method for conveying an interventional tool downhole in a substantially self-piloting fashion. The method includes moving the tool in the well while using a communicative conveyance line coupled to a winch at the oilfield surface. Thus, real-time readings regarding downhole tool speed, line tension, etc. may be analyzed at surface and utilized to adjust the moving of the tool in an ongoing feedback loop. As a result, the adjustments are made based on true circumstances downhole as opposed to surface-based readings which may otherwise be less accurate. Therefore, efficiency of the operations may be maximized, operator time freed and the likelihood of catastrophic line based failures reduced.

Abstract: An apparatus with a straddle packer for use within a wellbore. The straddle packer can include a tubular body comprising a first bore and a second bore and a first sealing element configured to seal against an inner surface of a casing installed within the wellbore. A second sealing element configured to seal against the inner surface of the casing, and the second bore can be located between the first sealing element and the second sealing element. An obstruction disposed in association with the tubular body, wherein the obstruction is movable between a first position in which the obstruction opens the second bore and a second position in which the obstruction closes the second bore.
