What she does, in full.

Petrophysics, geology, reserves and training.

Four service lines, the standards each is prepared to, and the formations and basins already worked. If what you need is not listed, ask: the answer will be a straight yes or no.

Petrophysical solutions tailored to your reservoir.

Petrophysical solutions tailored to better characterize your reservoir and to unlock the upside potential of your play and identify any bypassed pays. Interpretation from single wells to full field sets, in simple lithologies through to complex multi-mineral systems, using standard log analysis packages.

  • Single to multi-well petrophysical interpretation, simple through complex lithologies.
  • Integration of routine core analysis, special core analysis and specialty logs (nuclear magnetic resonance, dielectric and elemental spectroscopy) with production and test data, into realistic petrophysical models.
  • Sensitivity and cutoff analysis, with cutoffs set by rock type and calibrated to core rather than fixed once across a field.
  • Rock typing, petrofacies definition and saturation height modelling, integrating special core analysis (SCAL) data.
  • One-dimensional geomechanical models: elastic properties, overburden stress and pore pressure.
  • Russian-format log processing.
  • Log digitisation to LAS on request.

Framework first, then the maps.

Regional studies that establish the stratigraphic and structural framework before anything is mapped, so the maps mean something.

  • Regional stratigraphic frameworks with detailed lithostratigraphic and sequence-stratigraphic correlation.
  • Source rock thermal maturity and richness.
  • Regional hydrodynamics, including formation water composition, for migration and trapping.
  • Base, structure, isopach and maturity maps.
  • Reservoir property maps (porosity, net pay, water saturation) through to hydrocarbon pore volume and in-place volume maps.

Play and prospect analysis

  • Assessment of hydrocarbon potential within a basin.
  • Tight and fractured reservoir and shale play review.
  • Prospect and play evaluation with geological risk analysis and prospect ranking.
  • Contingent and prospective resource evaluation.

Numbers a board can defend.

Independent estimates prepared to recognised definitions, with the assumptions documented rather than summarised.

  • Reserves and resources evaluation under NI 51-101 and COGEH, and to SPE, WPC and SEC guidelines.
  • Year-end reserve reports and audit updates for securities-commission filings.
  • Reserve updates for acquisitions and divestitures.
  • Geological reports supporting TSX Venture Exchange listings.
  • Contingent and prospective resource assessment with probabilistic estimation.

Fourteen years of this work was done inside Sproule and Ryder Scott, where the reports carried a firm’s name. The method has not changed; the signature has.

Formation evaluation, taught by someone who still does it.

Petrophysical training courses scheduled at your convenience and customised to the size and level of the group.

  • Fundamentals in formation evaluation.
  • Reserves and resources evaluation.

Courses are built for the team that takes them, from petrophysics fundamentals to subsurface mapping, and worked on the team’s own plays where the data allows it.
