Injection-scheme design
Screen injection schemes before they consume scarce core material.
A physical coreflood test is slow, expensive, and it uses up core you don't get back — spend that budget on schemes worth confirming.
Contact temporarily paused — finalizing data-handling registration.
Business impact
Protect scarce core material for schemes that clear a screen first.
Coreflood testing is the confirmation method reservoir engineers trust — and it's also a queue: each run consumes core material, ties up lab equipment, and takes weeks to turn around. Screening candidate injection schemes on flow behavior first means the schemes that make it into that queue have already been checked against the physics.
- Core material reserved for injection schemes that clear a flow-behavior screen first
- A flow-behavior read available before a coreflood slot is committed, not only after
- A faster read on flow behavior while candidate schemes are still on paper
How we get you there
Relative permeability, viscosity, mineral-surface flow behavior, and chemical retention tendency
Candidate injection schemes are screened on core-scale flow behavior: relative permeability under Darcy-flow conditions, fluid viscosity, self-diffusion and ion behavior at the mineral surfaces your formation actually has, and mechanism-level chemical-adsorption tendency on those same surfaces — retention is the most common reason a formulation that looks good on the bench underperforms in a physical coreflood.
Computed relative-permeability curves
Pore-scale flow simulation, Darcy-flow benchmark — a mechanism-level read on displacement behavior ahead of a physical coreflood run.
Fluid viscosity
A property of the actual candidate fluid, not a generic reference-table estimate.
Self-diffusion & ion behavior
Transport behavior at named mineral surfaces — the same reservoir mineralogy a physical coreflood would test against.
Chemical-adsorption tendency
Mechanism-level ranking of retention tendency on the named mineral surfaces — not an absolute retention number (mg/g), which needs a physical core.
Viscosity, self-diffusion, and adsorption tendency are molecular-scale simulation (nanometer length, nanosecond-to-microsecond timescale); relative permeability is a pore-scale flow simulation benchmarked against Darcy-flow behavior — a mechanism-plausibility read at each respective scale, not a field-scale reservoir recovery-factor prediction.
In the published literature
Published accounts of chemical-EOR pilot design describe running a large number of cheap screening tests (e.g. simple pipette-scale tests) alongside a much smaller number of full corefloods during formulation optimization — using inexpensive methods to triage candidates before committing scarce core material and lab time to the more expensive coreflood stage.
Where this fits
A pre-screen ahead of a coreflood commitment
This narrows candidate injection schemes before a physical coreflood test confirms the strongest ones — it doesn't replace that confirmation step. The point is spending core material and lab-schedule time on a shortlist that's already cleared a flow-behavior screen.
Screen your injection schemes before they consume core material.
