An Interview with Dr. Olga Koper
Business Development/Sales Leader Energy, Battelle
Can you elaborate on the soy based surfactant that is looking very promising for a new green chemistry method?
Battelle is working on developing sustainable oilfield chemicals to reduce production costs as well as environmental impact while improving chemical performance. One such product is a cationic surfactant from soybean oil. The material has been formulated and it being tested for multiple oilfield applications.
How is this new surfactant developed?
Soybean oil, which is used as feedstock, is processed to yield a cationic surfactant. This surfactant is then blended with a co-solvent to optimize its solubility in water as most hydraulic fracturing fluids are water-based.
What are the initial results and how is this a better or “greener” method?
The surfactant is designed based on the principles of green chemistry. Our initial test results suggest the soy-based cationic surfactant shows no signs of estrogenic or anti-estrogenic activity based on BG1 Luc estrogen receptor transactivation test. Hence, our product is showing signs of promise of a greener technology as opposed to conventional cationic products.
Which companies are working on this project and how soon might it be used commercially? What benefits will it have over the current products being used?
Currently, Battelle is in talks with a variety of oilfield chemical companies and operators to further develop and optimize this technology. The technology is still in early stages of development. Time to market will depend on a host of factors, such as the technical progress during the next stage of development, commitment of the commercial client and the specific application of the product, i.e., enhanced oil recovery.
The benefits of using this product include:
- Lower production costs
- Reduced environmental impact
- Multiple wellbore applications
- Flexibility in surfactant design
What new technologies is Battelle working on related to nanotechnology? Not just in oil and gas but in other areas as well.
Nanotechnology is part of many applications, from design of catalysts to new sensors. One specific example is anti-icing and deicing technology for in-flight aircrafts based on a resistive heating using carbon nanotubes. This innovative coating solution is small in size, weight and power envelope and has unmatched performance in the industry. This coating can be used on drones when the weight constrains are of paramount importance.
And what do you see as the emerging trends in nanoscience that will revolutionize the world of engineering and have a big impact on society?
The largest impact is related to medicine, and particularly to drug delivery and early detection, particularly non-invasive using biomarkers. For example, designer nanoparticles can target specific cancer cells increasing treatment effectiveness and decreasing the side effects. Other areas are energy related, such as in energy storage (battery interfaces in Li-ion batteries) and harvesting (solar cells).
What are nanofluids and how are they used to enhance oil recovery? Why are they called smart fluids?
Nanofluids are solutions of nanoparticles (1-100 nm in dimension) and can be used in a variety of oilfield applications such as drilling, stimulation and improving oil recovery. Silica nanoparticles can alter the rock wettability of oil-wet reservoir rocks to water-wet thereby reducing the tendency of the rock to stay in contact with oil. This will eventually lead to higher oil recovery. Nanofluids also help control the mobility of injection fluids which in turn improves the sweep efficiency of injectates and therefore the resulting oil/gas recovery. However, a definition of smart fluids can be much broader and include materials that upon a stimuli will perform specific actions. This could include a controlled release from nano or micro capsules upon exposure to specific temperature, pressure, presence of ions, or other chemicals.
Why does the size of the nano-particles matter, and how is it measured? Do you use atomic force microscope?
For specific applications the size of the particles is crucial. For example, with carbon nanotubes in the deicing coating, the small size will provide lower weight of the coating, which is particularly important for drone applications, to extend the battery life during flights. In drug delivery applications not only size, but also shape and surface chemistry have a large impact on cellular uptake and overall treatment efficiency. Such correlations are studies using many methodologies including AFM.
How does the oil and gas industry use controlled release methods or encapsulation for oil production and why? Can you give examples?
An example of a controlled release can be delivery of the anti-scaling agents at the desired place and time. The controlled release can use different trigger mechanisms including temperature, pressure, presence of specific ions, etc. The type of the trigger is usually chosen based on the desired parameters, i.e., if you want the active ingredient to be released uniformly over a two-year period of time, or if you want to release it abruptly when the material reaches downhole conditions (specific temperature and pressure). The encapsulation approach eliminates using excess quantities of materials (cost savings and environmental benefits) as well as decreases labor associated with reapplication.
