Latest Patents

Toma's latest patents include groundbreaking technologies aimed at improving the extraction of viscous hydrocarbons. One of his notable inventions is a method and apparatus for extracting a viscous hydrocarbon from a productive substrate characterized by amounts of unconsolidated sand particles. This method involves introducing a hot, thermal stimulating medium at elevated pressure through the remote end of an elongated well liner. As the hydrocarbon becomes mobile, it is urged to the lower pressured segment of the liner. An expandable diverter, which is pervious to the stimulating medium, is positioned in the liner to form a quasi-barrier. This barrier is progressively lengthened to ensure the stimulating medium penetrates increasing lengths of the productive substrate, thereby assuring extraction along the entire liner length.

Another significant patent is focused on a well completion and method for improving the productivity of hydrocarbon emulsion from a substrate layer that holds the hydrocarbon. This completion includes an elongated, substantially horizontally disposed liner with perforated walls to receive the emulsion from the substrate. A flow of hot stimulating fluid is injected into the productive layer to achieve optimum penetration and maximum horizontal sweep. A flowable dam or gravel pack is placed at the completion remote end to facilitate the desirable distribution of the stimulating medium into the substrate while deterring the passage of emulsion back into the liner.
