Abstract: A borehole conveyance system that integrates wireline type downhole instrumentation into the drill string tripping operations that are typically performed in a borehole drilling operation to increase the types of measurements that can be obtained during the drilling operation and reduce equipment costs and maintenance costs. Certain wireline type tools can be used during drilling operations to yield measurements superior to their LWD/MWD counterparts, but not during any drilling operation in which the drill string is rotating while other types of wireline tools can be used to obtain measurements not possible with LWD/MWD systems.

Abstract: Disclosed herein is a borehole conveyance system that is conveyed within the borehole by a tubular such as a drill string. The conveyance system integrates wireline type downhole instrumentation into drilling and drill string tripping operations that are typically performed in a borehole drilling operation. This increases the types of measurements that can be obtained during the drilling operation. Equipment costs and maintenance costs can thereby be reduced. Certain wireline type tools can be used during drilling operations to yield measurements superior to their LWD/MWD counterparts and to reduce operation costs. Other types of wireline tools can be used to obtain measurements not possible with LWD/MWD systems. The rotation of the tool conveyance system and instrumentation therein is optionally controllable with respect to the rotation of the drill string by a selective locking subassembly (SLS).

Abstract: A measuring while drilling system typically has a metal pipework extending underground connected to an antenna. The metal pipework and the antenna are both connected to a type of downhole equipment. The antenna transmits or receives signals to/from a transceiver located on the surface, and the transceiver is connected to the metal pipeword and to a ground. The system is improved by joining a plurality of sections of wired drill pipe together to form a section where the antenna is integral with the metal pipework. One end of the section of wired drill pipe is joined to downhole equipment and another end is joined to a conventional metal pipework.
