Subsurface Analysis & Evaluation

Standard Petrophysical Evaluations

Standard Petrophysical Evaluations

  • Discrete well or multi-well analyses

  • Review existing petrophysical methodologies

  • Apply consistent workflow across wells in field

  • Uncertainty analysis and review

  • Petrophysical outputs for corporate databases and geological models

The evaluation of water saturation in a very thinly bedded Triassic North Sea reservoir contributed to significantly reduce the uncertainty of hydrocarbon volume in place and the economic viability of the field. The study integrated the results of resistivity modelling, core capillary pressures and petrographic analyses to deliver a petrophysical model honouring all data. This study was presented at the 2006 Devex conference.
