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.

Built-up evaluation shut-in tool operation controlled from the surface

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.

Monitoring casing annulus

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.

Downhole centralizer

The disclosure relates to a method for monitoring the performances of a cable for carrying a downhole assembly in a wellbore, the cable having at least a conductive core and an insulating outer layer, the method including:
