The use of polymer based chemical inhibitors has the advantage of utilizing chemical, macromolecular, and compositional (blends or block copolymers) towards chemical inhibitors whether it is for corrosion or scaling issues. It is important to understand the multi-phase condition of production fluids whether it is extraction or circulation (oil and gas vs geothermal brine). It is also important to understand the mechanism and the long-term action of inhibition from the fluid to the surface that is being protected. This talk will highlight the principles and work in investigating various corrosion and scaling inhibitors for the production and process industries. In particular, the use of block-copolymers and hyperbranched oligomeric design in inhibitors is of a high interest because of the multi-dentate and stability (or predictability) of their solubility in various phase conditions. While a number of these examples are highlighted in the design of new materials and dosing methods, it is important to stress the costperformance ratio of chemical inhibitors and their long term viability for continuous dosing from upstream to downstream. The work of the author also involves a number of analytical methods and testing methods that can be used to augment circulation fluids under high pressure and temperatures.
