Unlocking Resource Value
CES technology allows our customers to expand
their perspective on economically attractive
natural resources, whether it being stranded,
marginal, contaminated, or traditionally
uneconomic resources, or simply overcoming siting
or permitting issues by providing self-sustained
access to water, power, CO2, and more...
One of the truly differentiating aspects of CES technology that goes beyond its market applications in enhanced oil recovery and zero-emissions power plants is its tremendous and unparalleled fuel and product flexibility. CES combustors can be designed to being operated on a large variety of fuels, including those that are generally deemed uneconomic, marginal, or stranded. While currently concentrating on the commercialization of gaseous fuel resources, CES equipment has been demonstrated to run on liquid and even emulsified solid fuels.
With CES technology solutions you can rethink on how to unlock resource value previously considered unattractive. Our solutions let you assess resources beyond their conventional value and provide a unique opportunity when looking at:
Contaminated Natural Gas
Various reports estimate that 16% to 30% of the world's total reserves are contaminated with CO2 and other gases. In the past, these reserves have been considered uneconomical without the installation of expensive capital equipment to remove the CO2. Each of the available technologies for removing the CO2 have distinct disadvantages that include significant incremental operating costs, increased use of absorbing liquids at the site and the inability to economically remove high concentrations of the CO2.
CES' oxy-fuel technology now offers the opportunity for reservoir owners to realize increased value from these fields that can contain as much as 70% CO2. The value is realized by converting the contaminated gas into three revenue streams: electricity to meet utility power needs, CO2 to support EOR operations and potable water to meet local community needs. With CES' proprietary oxy-fuel technology, the contaminated gas is combusted in an oxygen environment producing a CO2 and steam gas stream that drives a turbine generator to produce power. The power is emission free since the gas steam, rather than being discharged into the atmosphere, is further processed into CO2 for EOR and then sequestered.. After producing the power, the gas stream is cooled with the steam condensing to water. A portion of the water is then recycled back to the combustion process with the remaining water than supplied into commercial market opportunity. The remaining, non-condensed gas stream is effectively 100% CO2 which is then compressed and distributed to EOR markets or recirculated back into the reservoir to further gas production.
CES' oxy-fuel technology provides new opportunities to reservoir owners, power producers, developers and commercial water entities. Contaminated gas reservoirs, previously considered as having minimal value, can now be commercially developed and achieve ROIs equal or greater than that realized by the premium fields. In addition, the CES technology increases the energy resources of a company/country since reservoirs previously dismissed as non-producible can provide major supplies of power, CO2 and commercial water into the market in addition to increasing oil production from adjacent fields with the newly available CO2.
Water becomes an increasingly scarce commodity
that often even makes or brakes energy projects,
from power generation to oil recovery. CES
technology provides several game-changing
dimensions to the water issue - unlocking resource
value by making water a valuable product or
byproduct of most of the solution cycles around
Inherently, CES combustors generate ample amounts of water by combining hydrocarbons with oxygen, contributing relevant volumes of clean, demineralized, water to the overall water balance of our facilities. This feature allows us to make our facilities largely water supply independent and even net water producers in air-cooled plant configurations.
More importantly, CES cycles provide efficient, emission-free waste heat that can be utilized for the desalinization of saltwater or produced brackish reservoir water to generate large amounts of potable, industrial, or agricultural quality water. Similar to conventional cogeneration plants, multi-stage flash desalinators (MSF) are powered by the exhaust heat of the OFJ-79 or OFT-900 turbines. More complex solutions may combine reverse-osmosis (RO) and thermal distillation processes to accommodate the needs of typical enhanced oil recovery field operations.
Finally, CES technology brings a truly new approach to water treatment in its G2S2 configuration which is optimized for heavy bitumen recovery in SAGD operations. The G2S2 process combines heat and steam generation with full water treatment capability into the combination of only two vessels. This allows for the elimination of costly water treatment alternatives, simplified permitting due to water consumption reduction, and greatly reducing the water disposal issue. While currently optimized for SAGD operations, the G2S2 water treatment alternative is likely to find broader applications across our target industries and has only seen the very tip of the proverbial iceberg...
