The shipment, storage, and processing of many produces, including oil and heavy petroleum products leave a large amount of oil sludge or coagulate in the shipping containers, tanks, and reaction vessels that is difficult to clean out. This reduces the amount of product delivered as well as reducing the capacity of the ship or container for the next load. Rhamnolipid’s surfactant and emulsifying properties are used to remove and recover the sludge and coagulates from the containers in an environmental manner.
Rhamnolipids for EOR
EOR stands for Enhanced Oil Recovery. It refers to the extraction or recovery of oil from an oil well that has played out using standard extraction methods. Typically only about 40% of the oil in a reservoir can be simply pumped out, with the last being very slow. To get the additional oil out, EOR methods are used, which may be expensive, toxic, and ineffective.
BioEOR stands for Biotechnology Enhanced Oil Recovery. It uses safe and effective biological compounds to accelerate the recovery of the remaining oil with a much higher recovery than other processes.
Exploration Risk vs. Recovery from known fields
As easily accessed reserved are depleted, the cost of finding, proving, and recovering more oil is skyrocketing. More and more of the potential oil is in environmentally sensitive areas, adding even more to the recovery cost wading through the permitting system and adding ever more sophisticated equipment. For the U.S., the problem is even worse as much of the ‘new oil’ is in foreign hands.
There are a huge number of oilfields, especially in the U.S., that have pumped most of their easily recoverable oil. If only 40% of the oil has been extracted using primary recovery techniques, then it is clear that getting an additional 40% of the oil out of those fields has great potential and low risk.
Temporarily Depressed Petroleum Prices
Although the world’s economies seem to be slowing and there is a focus on environmentally friendly forms of energy, there will still be a ravenous need for oil for many years to come before other energy technologies can come on-line. It is generally acknowledged that the current dip in crude prices is only temporary. It is enough to pull back on some investments on exploration.
Developing nations are rapidly increasing their need for petroleum.
As the United States economy grows, the Country’s dependence on foreign oil will also continue to grow. The Department of Energy (DOE) has estimated that over the next 25 years oil imports will double and unless additional domestic supplies are exploited a reliable supply of imported oil cannot be guaranteed. The nation’s dependence on imported oil, as a result, could soar to 70% by 2025. In order to reduce this reliance on foreign oil, new reserves of domestic crude oil must be found and extracted.
Global competition for petroleum will rapidly force prices higher as shortages appear. The newly emerging economies as well as the developing nations will continue their ever increasing demand for oil.
Enhanced Oil Recovery from Existing Oil Fields
As the expense and risk of new explorations has increased, the petroleum industry has moved toward other technologies to recover oil from existing fields and oil sand deposits. These methods focused on displacement of the petroleum, reducing its viscosity, or emulsifying it.
Within a mature oil field, the remaining oil tends to be heavy and lodged in the pores and fractures of the petroleum bearing strata.
Methods of displacement alone will never be completely effective due to the viscosity and adhesion of the oil to the strata and surface tension between the oil and the injected gas or flooded water.
To decease the viscosity and surface tension, heat may be applied as is done with the tar sands, but this is only minimally effective for oil wells.
The most effective way to increase recovery is with surfactants that can emulsify the oil. When an aqueous solution containing a surfactant contacts the small pockets of trapped oil, it reduces the interfacial tension (IFT) and mobilizes this trapped oil.
Using rhamnolipids as the surfactant is inexpensive, environmentally sound, and more effective than other chemicals. In a U.S. Department of Energy 3 year study, 42% of otherwise entrapped oil was recovered from a sand-pack using only 250 mg of rhamnolipids per liter of water.
BioSurfactant EOR, Inc.
BioSurfactant EOR has one of the most advanced methods to recover entrapped oil via an aqueous surfactant formulation that is injected into a mature oil reservoir, using rhamnolipids.
The BioEOR technology is the most effective Biotechnology option for Enhanced Oil Recovery (EOR). It produces faster recovery and more total recoverable oil than other technologies. It is far easier to use that competing technologies.
The advantages of the technology are:
1. Proven 40% plus release of entrapped oil
2. Better performance than synthetic surfactants
3. All natural, environmentally safe with no residual toxic hazards.
4. Economically priced to compete with synthetics and other EOR technologies
5. Minimal application effort and costs
6. Minimal well head equipment and material transport and storage costs
Department of Energy (DOE) has estimated that full use of next generation EOR in United States could generate an additional 240 billion barrels of recoverable oil resources.
Here is the technology to accomplish that goal.
Biosurfactant EOR, Inc.’s technology is superior to conventional EOR methods. Results show our technology is more effective, produces a higher yield, is easier to use, is non-toxic and is price competitive to other EOR methods.
