Nanomaterial-Enhanced Oil Recovery

Unconventional oil is trapped. We free it.

A material that reads its environment and responds accordingly.

The Problem

Tight reservoirs hold the oil. Conventional recovery can't reach it.

In unconventional plays, the rock that traps the oil and the fractures meant to release it both work against recovery. Smart Proppant attacks all three failure modes at once.

/ 01

The rock won't give

Permeability near 0.05 mD means oil is locked in pore space that conventional injection simply cannot sweep.

/ 02

Fractures channel, not sweep

Injected CO₂ races through natural fractures and breaks through, leaving the matrix untouched. Adding fractures cut recovery by 53%.

/ 03

No control downhole

Once gas is in the formation, operators lose the ability to steer where it goes or how long it stays productive.

The Particle

Cenospheres that armor a foam film.

Class C fly ash, magnesium-doped, amphiphilic at the surface. Small enough to ride supercritical CO₂ into the fracture network. Reactive once it arrives.

How It Works

A material that responds to the reservoir.

Across each huff-and-puff cycle the system activates in sequence, stabilizing the foam, diverting flow away from thief fractures, and redirecting pressure into fresh rock.

1

Inject

Mg-FANPs delivered in supercritical CO₂ foam enter the fracture network.

2

Stabilize

Nanoparticles bridge foam lamellae, raising effective viscosity and resisting breakthrough.

3

Sense

The material reads reservoir conditions: temperature, pressure, pH and carbonate chemistry. Thermally gated, so it stays inert until it arrives.

4

Divert

Accumulation is flux-selective. The fastest pathways block themselves, redirecting pressure into the matrix while the rest of the network stays open.

5

Recover

Fractures drain the matrix on production. Conformance improves cycle over cycle, so recovery compounds.

Simulation Results

The effect is cumulative.

Both wells produce almost nothing for two years. Then the treated well departs. Conformance improves cycle over cycle and recovery compounds, which is why the uplift arrives late rather than immediately.

Why It Matters

Built from waste. Engineered for control.

Smart Proppant engineers a reactive nanomaterial from Class C fly ash, deployed in CO₂ foam to enhance oil recovery in tight, oil-bearing rock.

Cycle 00

At well scale (~60,000 STB, $70/bbl) the $1.5M treatment is recovered after the late-cycle departure. Not on first injection.

Regulatory Alignment

A Class II operation that produces Class VI-grade permanence.

Enhanced recovery and geologic carbon storage are separate well classes, separate permits, separate economics. One injection does both.

CLASS II

Enhanced recovery

The largest category of injection well in the United States. Existing permits, existing infrastructure, existing operator workflows. Mg-FANP deploys in a standard huff-and-puff programme at standard pump rates.

+
CLASS VI

Geologic sequestration

CO₂ mineralized into a stable carbonate phase in place, not held beneath a caprock but chemically bound into the rock. Permanence by reaction rather than by containment.

Waste already goes underground. Ours does work on the way down, recovering oil and locking carbon into the formation as it goes.
