Abstract

An apparatus, method and system for communicating information between downhole equipment (40) and surface equipment is disclosed. The electromagnetic signal repeater apparatus (34, 36) comprises a housing (102) that is securably mountable to the exterior of a pipe string (30) disposed in a wellbore (32). The housing (102) includes first and second housing subassemblies (104, 106). The first housing subassembly (104) is electrically isolated from the second housing subassembly (106) by a gap subassembly (108) having a length that is at least two times the diameter of the housing (102). The first housing subassembly (104) is electrically isolated from the pipe string (30) and is secured thereto with a nonconductive strap (120). The second housing subassembly (106) is electrically coupled with the pipe string (30) and is secured thereto with a conductive strap (122). An electronics package (127) and a battery (126) are disposed within the housing (102). The electronics package (127) receives, processes and retransmits the information being communicated between the downhole equipment (40) and the surface equipment via electromagnetic waves (46, 48, 50).
