Nautilus Ultra Suite

Get reliable formation evaluation in challenging ultra-HP/HT environments

The Baker Hughes Nautilus Ultra™ suite of logging services is specifically tailored for reliable formation evaluation in challenging ultra-HP/HT environments. Our tools are rated for wireline logging operations at temperatures up to 500 deg. F [260 deg. C] and pressures up to 30,000 psi [206 Mpa].

Our suite of Nautilus Ultra HP/HT services include

  • array resistivity from high-definition induction log (Nautilus-HDIL™)
  • fullwave monopole and cross-dipole acoustic log (Nautilus-XMAC™)
  • spectral gamma ray data (Nautilus-DSL™)
  • formation bulk density and Porosity determination (Nautilus- CDL™)
  • compensated neutron porosity analysis (Nautilus-CN™)
  • cablehead tension, borehole temperature, and mud Resistivity sensor sub (Nautilus-TTRM™) borehole geometry from a three-arm caliper.
