Apparatus, methods and systems for downhole testing of electronic equipment

Abstract

A carrier device is provided for temporary installation downhole in a well. The carrier device is a robust device that is divided by a pressure bulkhead into a first section having an inductive coupler, power electronics, and a telemetry unit, typically all formed using multi-chip-module type electronics, and a second section with at least one test device typically using printed circuit board technology that may include sensors or transducers coupled to a communications bus and/or a power line that extends to the first section via the pressure bulkhead. The carrier further includes a mechanism that permits the carrier to be pulled out of the wellbore, and may include a mechanical locating element, typically adjacent the inductive coupler that permits the carrier to be located in the wellbore so that the inductive coupler will be located adjacent an inductive coupler in, on, or behind a liner or casing of the wellbore.
