Mudlogging & Onsite Geo-Analysis Services

Petro Geo Consult’s onsite wellsite geology team delivers continuous, real-time subsurface intelligence from the moment the bit breaks formation to the final total depth log run. Our geologists are embedded on the rig floor and in the mudlogging unit, integrating drilling parameters, cuttings analysis, gas chromatography, and LWD data into a coherent geological picture that drives faster, safer, better-informed drilling decisions. We operate across all major US unconventional basins and deploy on conventional exploration wells, appraisal programmes, and multi-well pad developments.

Wellsite geology is a discipline that demands rigorous real-time interpretation under operational pressure. Our geologists have an average of twelve years’ field experience and are trained to integrate multiple data streams simultaneously — mudlog, LWD gamma ray, resistivity, neutron-density, offset well correlations, and pore pressure indicators — to provide drilling engineers and company men with clear, actionable guidance on casing points, formation tops, bit optimisation, and wellbore placement. Every well benefits from a comprehensive post-well geological report that feeds into future drilling programmes and landing zone optimisation studies.

Our commitment to safety is reflected in zero recordable incidents since 2016. We operate under a culture where every geologist is empowered to call a safety stop if conditions demand it, and where work-life balance and crew welfare are treated as operational priorities, not afterthoughts. We believe motivated, well-supported geoscientists produce better science — and that better science produces better wells.

Our Onsite Service Offerings

Full-Service Wellsite Geology

  • Continuous 24/7 wellsite geology coverage with 2-geologist rotations to maintain peak analytical quality throughout the well.
  • Real-time lithological description from drill cuttings with photographic documentation and lag-depth calibration.
  • Gas chromatography (C1-C5), total combustibles monitoring, and UV fluorescence screening for hydrocarbon show detection.
  • Formation tops identification and stratigraphic correlation against regional well databases and offset well data.
  • Pore pressure and wellbore stability monitoring using d-exponent, Sigmalog, and gas ratio trend analysis.

Real-Time Geosteering Support

  • Horizontal well placement and landing zone optimisation integrating LWD gamma ray, resistivity, and neutron-density.
  • Real-time steering recommendations based on sub-metre-scale formation boundary detection and structural dip interpretation.
  • Casing-point and bit-change recommendations supported by quantitative lithology and formation strength analysis.
  • Direct data feed to remote operations centres via WITSML for simultaneous onsite and remote geo-analysis coverage.

Hybrid & Customised Programmes

  • Flexible staffing models from single-geologist coverage on development wells to full multi-well pad teams with a field coordinator.
  • Software-neutral platform compatibility — our geologists work within your existing WITSML infrastructure, EDR system, and geosteering software environment.
  • Detailed end-of-well geological reports including drilling synopsis, stratigraphic column, gas and shows summary, and formation tops tabulation for every well.
