shale rock structure

In-situ GOR assessment

This is done using PhaseKinetics, PhaseSnapshots and FT-ICR MS

Deliverables

We supply:

14-compound PVT model for comparison of phase envelopes with those in engineering reports, including assessment of production fractionation.

Samples (5g)

You provide:

Engineering reports, and shales with maturity just less than at the production site.
Geochemical screening is used to select the key samples.

Components

Closed system MSSV pyrolysis

  • Instantaneous composition reproduces GOR.
  • Differences between predicted phase envelopes and those from engineering reports are used to assess production fractionation in terms of C7+MW and GOR.
  • Differences can be large or small (usually 20-40%).
