  • Method, system, and optimization technique to improve oil reservoir recovery in the Water-Alternating-Gas injection process by using downhole control valves (WAG-CV)
    Patent number: 10428632
    Abstract: A system for Water-Alternating-Gas (WAG) injection for Enhanced Oil Recovery (EOR) includes a mechanical well configured to enable multi-point selective injection for water and gas. The system further includes an optimization engine configured to calculate reservoir flow dynamics and selectively inject water and gas via the mechanical well according to reservoir flow dynamics.
    Type: Grant

    Date of Patent: October 1, 2019
    Assignee: LANDMARK GRAPHICS CORPORATION
    Inventors: Gustavo Carvajal, Michael Konopczynski, Alejandro Chacon, Steven Knabe
  • Optimizing oil recovery and reducing water production in smart wells
    Patent number: 9745833
    Abstract: A method and non-transitory program carrier device tangibly carrying computer executable instructions for adjusting downhole valve settings in order to optimize oil recovery and reduce water production from a well. The method and non-transitory program carrier device are particularly advantageous in wells with intelligent completions that are often referred to as smart wells. In the oil and gas industry, an Internal Control Valve (ICV) is an important tool for both reactive and proactive approaches to adjust ICV settings to improve oil recovery.
