  • Access Bit
    Allows downhole sensors access to open hole during through drill pipe operations....

  • During through-drill-pipe operations, Signum logging tools gain access to the open hole by passing through the bottomhole assembly (BHA). Comprised of the optional float-valve sub, deployment sub and access bit or mule shoe, the BHA makes it possible to bypass trouble zones, drill through bridges, complete reamer runs and maintain well control, all while maintaining access to the borehole. Not getting logs to bottom is no longer a problem with the Signum conveyance system.
  • Intelligent Waveform Sonic (iWS)
    Acoustic porosity tool with open hole and cased hole applications....

  • The iWS acoustic tool was designed for acquiring high-resolution, full-wave acoustic data. The tool features a monopole transmitter and a five-receiver array, which records waveforms at each receiver, while obtaining formation-integral travel time (Δt) and shear (Δt) in fast formations. The iWS requires a fluid-filled borehole and can be used in fresh, salt or oil-based mud systems. In cased holes a traditional cement bond log can be produced.
  • Centralizer
    Properly position your sensor package in the wellbore with Signum accessories....

  • Centralizers optimize tool position while minimizing environmental effects. With the ability to fully collapse to a 2.25-inch diameter, Signum centralizers offer a through-tubing-capable solution for conventional, directional and horizontal well-bore applications.
