I joined SLB in 2005 as a chemical engineer in the Novosibirsk Technology Centre, focusing on the development of proppant flow control additives (PropGUARD technology) used in well stimulation and elastomers for the oil swell packers (ResPack, Completion). In 2009 I joined Schlumberger Cambridge Research. The main focus of my work throughout my SCR career has been on controlled proppant agglomeration for heterogeneous proppant placement (next generation HiWAY), corrosion chemistry and drilling fluid formulation. I conduct research on acid and production corrosion inhibitors, mechanisms, and performance with a view to developing new enhanced corrosion inhibitor formulations for the Well Intervention, Matrix Acidizing and CTS, Wireline and M-I SWACO PT business segments. Since 2018 I was working in the Fluids & Materials programme in the Well Construction on development of new high-performance drilling fluid additives.
