With a total of 2 patents, Kalfayan's work focuses on innovative methods that enhance the efficiency of fluid flow models and acidizing processes.

Latest Patents

Kalfayan's latest patents include a fluid flow model and a method of using the same. This fluid flow model consists of one cross-flow style core holder and multiple standard style core holders, interconnected by a combination of serial and parallel flow paths. The design allows for a fluid flow model that closely approximates a small radial slice of a conventional reservoir. This model is particularly useful for estimating the necessary treatment fluid for acidizing and water control methods.

Another significant patent is the acidizing stimulation method using a pH buffered acid solution. This method is designed for stimulating subterranean formations in oil and gas wells, particularly sandstone formations. The pH buffered acid system can be utilized as a preflush or overflush, or both. The method involves introducing a hydrofluoric acid-containing sandstone acidizing solution either before or after the pH buffered acid system. This innovative approach can also be applied to carbonate reservoirs, ensuring that the pH of the buffered acid solution aligns with that of the acidizing solution.
