Abstract: Up to date, oil and gas have contributed the largest share of global primary energy that powers our civilization. Therefore, functionaing of our global economy and our well-being depend on these fossil fuels. More importantly, any energy transition to alternative technologies depends on the fossil fuels. This fact, together with the growing population, accelerates depletion of oil resources. Now more than ever, our energy future depends on improving extraction methods of oil and gas. The largest carbonate oil field – Ghawar – is located in Saudi Arabia. Even a few percent of incremental recovery from this giant field will yield substantial amount of oil. Tertiary recovery alternatives that require addition of polymers, surfactants, etc. are expensive, especially on such a large scale. On the other hand, injection of inexpensive seawater or modified salinity seawater seems to be economically feasible. We have not yet reached the level of understanding of modified or low salinity waterflooding process to efficiently use it as an oil recovery technique at field scale. In this seminar, I will talk about several important aspects of modified salinity waterflood with the focus on carbonate surface chemistry, crude oil deposition mechanisms, reactive transport and ion-exchange in carbonates. The purpose of the talk is not to give comprehensive overview of the modified salinity flooding, but rather highlight the difficulties that hinder our fundamental understanding of the process.
Biography: Thanks to a classical chemical education, Dr. Maxim Yutkin is interested in both practical and experimental research. In his early career he has dedicated a lot of attention to synthetic coordination chemistry and in particular porous metal-organic frameworks. More recently, Yutkin is investigated the chemistry of fracturing fluids and their interactions with proppant and rock.
