Miscible-gas EOR

Phase-behavior miscibility screening for CO2 and hydrocarbon-gas EOR.

Before you commit to a slim-tube test, know roughly where minimum miscibility pressure sits for your reservoir fluid at reservoir temperature.

Business impact

Don't find out a gas-injection scenario is off-target after a slow, expensive test.

Slim-tube testing is the industry-standard way to confirm miscibility — and it's slow and costly to run on every candidate injection scenario. An early, physics-grounded read on where miscibility roughly sits lets you prioritize which scenarios actually earn that commitment, instead of working through a test queue to find out.

  • Slim-tube test slots prioritized by an early physics read, not worked through blind
  • Faster prioritization across candidate gas-injection scenarios
  • An early read on miscibility before committing test-program time and budget

How we get you there

Minimum miscibility pressure and first-contact miscibility screening

CO2 and hydrocarbon-gas injection scenarios are screened for miscibility behavior against your reservoir fluid at reservoir temperature, for your injection-gas composition — an early triage step ahead of physical slim-tube testing, not a substitute for it.

Miscible-gas EOR screening

Multiple-contact (dynamic) MMP and, where the injection gas warrants it, first-contact miscibility pressure — a mechanism-plausibility read, not a substitute for physical slim-tube confirmation.

Bulk-continuum phase-behavior modeling (equation-of-state flash and phase-envelope calculations) — not molecular-dynamics simulation, and not a field-scale reservoir recovery-factor prediction.

In the published literature

Published field studies have determined minimum miscibility pressure for CO2 injection against a specific reservoir crude — a threshold below which displacement becomes materially less effective. Establishing that threshold before committing to a field-scale CO2 flood is the kind of screening question this page addresses.

Where this fits

A faster early read, ahead of a slim-tube commitment

Slim-tube testing is the industry-standard confirmation method — and it's slow and expensive to run on every candidate. This gives an early, physics-grounded read on which gas-injection scenarios are worth that commitment.

Scope your injection scenarios before you commit to a slim-tube test.
