Taking the Guesswork Out of Enhanced Oil Recovery

How do you select an Enhanced Oil Recovery (EOR) strategy for maximum results? Battelle has developed an innovative business model to help oil producers take the guesswork out of EOR—without spending a dime up front.

Battelle is currently working with small and mid-sized oil producers in Ohio to optimize EOR efforts and maximize the amount of oil recovered. In many of the oil fields in the region, only 10-15% of oil can be recovered through primary production. With large producers snapping up leases for the shale gas boom, options are limited for small producers who want to expand their operations. By using EOR methods, producers can extend the life of their existing wells and increase their lifetime production by 50-100%.

But it’s not always easy for producers to know the optimal EOR strategy in advance, or estimate the amount of oil they will be able to produce. Battelle uses the latest reservoir modeling tools to estimate future well productivity and evaluate different EOR scenarios. By looking at the reservoir models as well as the local geology, available resources, and resource costs, the Battelle team is able to help producers select the strategy with the highest return on investment. Because smaller producers are not always able to invest in this kind of advanced analysis up front, Battelle makes these services available for a percentage of future revenues on the wells they are analyzing.

In one case, Battelle is helping a group of producers in Ohio maximize the remaining production in a declining oil field. Battelle estimated the future production for the field using their EOR design tool. Then, they used the design tool to evaluate how different scenarios for EOR would impact the individual wells together and separately. The analysis showed that by pooling the leases together, production for all producers would be higher than if they continued to operate separately.

Battelle has decades of experience in the oil and gas industry, and advanced computational tools developed through years of government and industry research. Now, these tools that were previously available only through large complex government science contracts are accessible and affordable for even small producers.
