BioEOR

Primary oil recovery efforts leave 70-80% of oil in place. Secondary efforts recover an additional 10%-20% of the original reserves, leaving at least 50% of the reservoir’s recoverable oil behind. When BioEOR is deployed in mature waterfloods, operators can achieve a 1-5% uplift in cumulative oil production.

Most EOR methods utilize mechanical engineering techniques that make broad chemical changes to the reservoir. TTI’s BioEOR approach is different. We focus on biology and aligning with the reservoir’s existing environment. BioEOR stimulates and accelerates biological mechanisms that have evolved over millions of years with almost no interruption to your operation.  

How BioEOR works.

Biology is the foundation of TTI's patent-protected BioEOR process. Our unique approach aligns with a reservoir's existing environment. BioEOR stimulates and accelerates mechanisms that biology has evolved over millions of years. Some types of microbes produce methane from oil molecules. Adding BioEOR custom chemical solution to a mature waterflood can increase the concentration of methane, which enlarges the size of the swept zone — the areas within a reservoir that contain stranded oil. Areas where oil has previously been swept to producing wells are filled with methane bubbles, and flow diversion occurs. Because water seeks the path of least resistance, water travels to new areas in the reservoir that were not contacted during earlier recovery efforts. Reaching these areas increases oil recovery and production.

After secondary recovery efforts, 50-70% of oil left behind.
Adding the BioEOR custom solution to a mature waterflood can increase the concentration of methane and enlarge the swept zone where oil is stranded.
 
With former pathways now partially blocked, water travels to new areas not contacted during earlier recovery efforts. Reaching these areas increases oil recovery and production.

Can it work for us?

Whenever microbes are resident in oil reservoirs, the potential for BioEOR application exists. A confirmation water sample determines if your reservoir is populated with the correct microbial community for BioEOR to be effective. Other environmental conditions are measured to determine if a reservoir is suitable, including downhole temperature, salinity and sulfate concentrations.

TTI’s BioEOR process is clean.

Unlike other EOR methods, BioEOR does not require operators to drill new wells or to treat water. The chemical solution customized to your reservoir is premixed in containers, eliminating the need for blending on site.

TTI's turnkey system arrives at your site in a small skid-mounted unit with a standard pump delivery system that is easy to operate. The system has minimal moving parts, is easy to maintain, requires few repairs if any and requires minimal data collection.

A full treatment of the BioEOR solution can be delivered in as little as three months, depending on the size of the field.

TTI’s BioEOR process is safe.

The chemicals we use are comparable to those commonly used in most oilfield operations.

When we install our compact, skid-mounted system, we provide onsite training. Each unit comes with a custom hazard mitigation plan that includes safety data sheets, safe handling instructions and cleanup instructions for use in the unlikely event of a spill.

TTI’s BioEOR process is proven.

The TTI process is based on nearly two decades of scientific research that has resulted in more than 70 patents. Beyond the lab, we have conducted comprehensive research all over the world and identified projects across the globe.

We have also assembled extensive databases of the biological and chemical characteristics of multiple oil and gas fields.

BioEOR has successfully been used in commercial operations in Oklahoma and Montana. It is currently in use in Canada’s Jenner field in partnership with oil and gas producer Cor4 Oil Corp.
