Next release of VPem3D and VPview due December 2019


Fullagar Geophysics provides interpretational expertise, software solutions, research, and training to the mining industry, worldwide. Our specialities include integrated interpretation of electromagnetic, gravity, magnetic, and borehole data for both exploration and mining applications. Our aim is to extract maximum value from our clients' data.


  • Gravity, TMI, gravity gradient and magnetic gradient modelling and inversion - VPmg is a very flexible 3D modelling and inversion package, for both "unconstrained" and geologically-constrained interpretation. VPmg can be run either stand-alone or via Mira Geoscience's Potential Fields Module. {visit Mira web site for details}

  • TEM conductivity-depth transformation - The Emax and EmaxAIR CDI programs rapidly transform ground and airborne transient electromagnetic time decays into conductivity-depth pseudo-sections. Emax and EmaxAIR can be run stand-alone or via EMIT's Maxwell software. {visit EMIT web site for details of Maxwell}
  • 1D TEM inversion - VPem1D performs layered earth inversion of airborne and ground transient electromagnetic (TEM) data, both "unconstrained" and geologically-constrained. VPem1D uses the same model formats and inversion styles as the VPmg gravity and magnetic software.  {visit Mira web site for details}
  • 3D TEM inversion - VPem3D performs fast approximate 3D inversion (both “unconstrained” and geologically-constrained) of airborne, ground, and downhole transient electromagnetic (TEM) data. Decays are converted to resistive limits in order to achieve run times 10 times faster than conventional 3D TEM programs. VPem3D uses the same model formats and inversion styles as the VPmg gravity and magnetic software.

  • Auto-picking of televiewer images - Sinepick interprets planar structures (sinusoids) and breakout features from acoustic and optical televiewer images.
  • Geophysical tomography - ImageWin generates tomographic images from cross-hole and cross-gallery radio, radar, and seismic data. It includes interactive data reduction options.
  • Automated borehole log interpretation - LogTrans performs rapid interpretation of wireline logs and other borehole data.
  • Quality appraisal of wireline logs - LogQA assesses reliability of wireline logs with reference to generic and user-based criteria.


Peter Fullagar has over 30 years experience in base metal, precious metal, and petroleum exploration, and in metalliferous and coal mining geophysics. He worked for 12 years with WMC Exploration Division in Australia, including 3 years as Chief Geophysicist. He was the inaugural Chair of Borehole Geophysics at Ecole Polytechnique, Montreal, in 1993-94, and served as team leader in 1995-96 for the CMTE/AMIRA P436 research project on Application of Geophysics to Mine Planning & Operations. Peter is an Adjunct Professor at the WH Bryan Mining Geology Research Centre, University of Queensland.

Philip Muir is a geophysicist with experience in precious metal and base metal exploration who has been working in the mineral exploration industry for 34 years. For 22 years he worked with WMC Exploration Division in Australia, including 3 years in Kalgoorlie, 11 years in Adelaide initially as the geophysicist for the Stuart Shelf / Olympic Dam before adding responsibilities for other exploration projects and a broad range of geophysical data and software issues, followed by 8 years in Perth. Since 2002 he has been living in Tasmania and working as a private geophysical consultant.
