BERO™ biosurfactant technology can not only greatly improve oil recovery rate, but also greatly reduce water injection and water cut of produced liquid, lower energy and machinery consumption, improve the efficiency of production well systems and prolong workover-free period. The production of crude oil greatly increases while production cost is lowered, so remarkable economic benefit is gained.

As for cost reduction seen from the practical application effect, in recent years,
the average water cut of onshore oilfields has been as high as 82% and
onshore oilfields enter the development period of high water cut. Oil-water
separation and sewage re-injection greatly increase energy consumption,
which makes oil production nearly profitless and forces some old oilfields to
reduce production. BERO™ biosurfactant technology can not only greatly
improve oil recovery rate, but also greatly reduce water injection and water cut
of produced liquid, lower energy and machinery consumption, improve the
efficiency of production well systems and prolong workover-free period. The
production of crude oil greatly increases while production cost is lowered, so
remarkable economic benefit is gained.
As for environmental problem seen from the perspective of development,
generally speaking, exploration and development and long- distance
transportation of crude oil will irreversibly damage and seriously affect the
environment and affect the soil and biological environments of some areas.

Most production wells have entered into secondary recovery; most commonly
used chemical and physical secondary recovery technologies are
internationally considered as efficient and environmentally harmful
technologies and have been restricted or prohibited in some advanced
countries; and the cost for improving those restricted technologies is very high.
In this case, due to the limitations of technology, the environmental protection
performance of oilfields face many problems, the surfaces of many oilfields are
barren and ecological environment cannot be restored within several decades.
In recent years, national industrial policies and energy policies explicitly
specify that processes, equipment and products requiring high energy
consumption and causing environmental pollution shall be eliminated.
Environmental problem has attracted a lot of attention from people from all
walks of life and people are more and more aware of effectively protecting
ecological environment during oilfield development. As a non-acidified
preparation, BERO™ biosurfactant will not cause the secondary pollution of
formation or disturb crude oil dehydration and sewage treatment systems and
it can prevent secondary plugging since it produces no other new ramification
during reaction. It is biologically degradable, will not corrode or pollute facilities
(such as pipes) and surrounding environment or do harm to human or animals,
so it is an environmentally friendly product. This product totally meets the HSE
requirements for working environment during oilfield development. Even
though well selection and technical deviation could not achieve expected result,
it will not damage production well and formation.
Therefore, BERO™ biosurfactant has obvious advantages over other existing
enhanced oil recovery technologies. It brings considerable economic benefit
as well as environmental and social benefits and is beneficial to the harmony
between oilfield development and environment and sustainable development.

Comparison between BERO™ biosurfactant technology and technologies
such as acidification, fracturing and polymer flooding:
As for conventional technologies such as acidification, polymer flooding and
fracturing, due to their own limitations, they cannot achieve ideal effect or only
have short-term effect and may cause secondary pollution of reservoir. For
instance, if acidification is adopted to remove plug, high acid concentration is
required, effective action radius is often small and substances dissolved by
acid may cause new plug, so it only has short-term effect. This method
possibly results in damage of reservoir and environment and corrosion of
equipment. As for fracturing, it can only act on fractures and will fast increase
water cut. As for polymer flooding, produced wastewater not only has high oil
content, but also contains a lot of polymer, thus increasing liquid viscosity,
improving the oil carrying capability of liquid and also increasing difficulty in
water-oil separation.
Compared with the above methods, BERO™ biosurfactant technology
prevents their disadvantages perfectly:
