Abstract: A mud pulse landing assembly (10) which allows for the removal of the mud pulse generator (16) containing the mud pulse orifice (106), thus creating an unobstructed passageway for any tool or instrumentation that may need to be passed through the drill string. The retainer (14) of the mud pulse landing assembly also provides a universal mount for engaging alternate tools or instrumentation for use in analyzing the borehole geology. The retainer (14) is positioned between the mud pulse generator (16) and the landing sub body, so as to protect the retainer from the turbulent and abrasive mud flow, and to prevent obstruction of the area downstream of the compact muleshoe (60).

Abstract: A communication method for retrieving stored data from an MWD tool, through an antenna used for conventional EM data telemetry. The method comprises establishing electrical contact between a surface transceiver and an EM data telemetry antenna upon retrieval to the surface. The MWD tool then transfers data through the antenna, the data being received by the surface transceiver. Also provided is an electrical isolation connector subassembly comprising an electrically insulative coating to electrically isolate the splitsub components, thereby forming the antenna for data transfer and EM data telemetry.
