Power and CO2 for EOR

Standalone Module for
Independent CO2-Flood Operations

Our standalone power module is an example of the technology we commercialize.  This provides independent CO2 and power to smaller oilfield operators who wish to increase production through tertiary oil recovery.

Our standardised power plant produces a nominal 7 MMcf/d of pipeline quality compressed CO2. This is equivalent to 120,000 tonne per year.

We can build, own and operate the power plant on the basis that we receive wellhead reservoir gas as fuel feedstock.

We thus reduce the need for expanding the centralised gas treatment facility and provide pure CO2 at the injection wellhead.

This significantly reduces the investment required by the field operator for surface facilities and compression equipment.

The wellhead reservoir gas is an ideal fuel source for our unique oxygen-based combustion technology that has been demonstrated by Clean Energy Systems at their Kimberlina Power Plant, near Bakersfield, Ca.

We also provide a nominal 4 MW of power to the region; enabling field investments to be planned independent of local power utilities or availability of CO2 through a pipeline infrastructure.

Our favourable project economics (shown adjacent) results from our ability to convert CO2-contaminated reservoir gas into incremental oil and electricity in one process.

Each module also produces around 16,400 gall/day of industrial quality water and we have available 135,000 tonne per year of Nitrogen that is currently used for chilled water-cooling before being vented to atmosphere.

The power plant has no flue stack and is therefore eligible for fast-track permitting similar to renewable energy sources.

The total plant investment cost depends on field requirements, but is typically in the order of $20 million -- inclusive of all CO2 drying and compression equipment.

Project development cost is around 10% of the capital expenditure with a construction period of less than 15 months from the time an investment decision is taken.

Although price of delivered CO2 to the injection well depends on field specific investments, we can indicate here that we are targetting a cost (in $/Mcf) that is equivalent to 2.0 - 2.2% of the oil price in $ per barrel.

(With oil at $80 /bbl this is in the order of $28 per metric tonne of CO2.)
