Surface Interface Box (SIB)

The Surface Interface Box is a complete MWD mud pulse decoding and data distribution system. The unit incorporates sophisticated filtering techniques for reliable data decoding in high noise environments from the Standpipe Pressure Transducer.

The unit also provides support for a Rig Floor Display and WITS connectivity, including and Ethernet connection. The SIB is directly compatible with the Geolink surface and downhole system, and is supplied in a robust, modular case for reliable field use.

  • Digitally adjustable internal filter clock
