Patent number: 10018746Abstract: An apparatus includes a sub with recesses along an exterior wall to receive inserts, an antenna case including a coil surrounded by a sacrificial wear portion of a material through which signals between the coil and a formation of interest may pass. An eroded outer wall of the sacrificial wear portion is restorable by application of an uncured restorative material to the antenna case. A method includes securing an antenna case having a coil there within onto a sub, surrounding the coil with a metal sleeve shield, and radially receiving and securing a multi-piece sacrificial wear member intermediate the antenna case and a retainer ring having a threaded bore. The multi-piece sacrificial wear member is replaceable after use by unthreading the retainer ring to release the sacrificial wear member for radial removal from the sub.Type: GrantFiled: November 10, 2015Date of Patent: July 10, 2018Assignees: Oliden Technology, LLC, China National Petroleum CorporationInventors: Chidiebele Gabriel Okonkwo, Qiming Li, Anzong Li, Chuanwei Li, Jun Zhu

Patent number: 9880313Abstract: A system and apparatus for configuring a well logging assembly having an elongate sub with a bore therethrough, a leading end connection and a trailing end connection, a plurality of sets of recesses in an exterior wall of the sub to receive a plurality of sets of inserts, each having a threaded exterior surface, a plurality of internally threaded retainer rings, and a plurality of well logging devices securable to the exterior wall of the sub using the retainer rings to threadably engage the inserts received in the recesses. The system enables convenient configuration and reconfiguration of the well logging assembly by enabling convenient securing of a first well logging instrument to the sub at a variety of spacings from a second well logging instrument to provide a variety of depths of investigation into a geologic formation penetrated by a drill string containing the well logging assembly.Type: GrantFiled: November 10, 2015Date of Patent: January 30, 2018Assignees: Oliden Technology, LLC, China National Petroleum CorporationInventors: Chidiebele Gabriel Okonkwo, Qiming Li, Anzong Li, Chuanwei Li, Jun Zhu
