EOR/IOR Strategy Optimization

In one sentence

Searches injection strategies — what to inject, where, and at what rate — against recovery and cost together.

The problem

EOR screening usually compares three or four pre-selected schemes because each evaluation costs a simulation campaign. The optimum is rarely one of the four.

How it works

The proxy simulator is placed inside a multi-objective optimiser that searches injectant, pattern, rate and timing against recovery factor and discounted cost. The Pareto front is presented to the team rather than a single recommended scheme.

Data required

  • History-matched model ensemble
  • PVT and fluid characterisation including injectant compatibility
  • Injectant availability and cost, including CO2 or gas source constraints
  • Facilities and injection capacity limits

What you get

  • Pareto front of strategies across recovery and NPV
  • Sensitivity ranking of the decision variables
  • Pilot design recommendation with the decision it is meant to resolve

What it cannot do

Everything here inherits the proxy’s limits and the history match’s biases. Chemical EOR in particular depends on laboratory parameters — adsorption, degradation at reservoir temperature — that simulation handles crudely, and a favourable simulated result for a chemical flood should be treated as a reason to run a core flood, not as a decision.

Every capability page states a real limitation. If a vendor cannot tell you where their product stops, you are not being told the truth about where it starts.
