A University/Industry Consortium for Natural Gas Production, Transmission, and Storage Systems Optimization

The University of OklahomaProfessor F. Hank Grant (Industrial Eng.)Professor Faruk Civan (Petroleum Eng.)

Professor Miguel Bagajewicz (Chemical Eng.)


Objectives

Establish an Industry/University Consortium

Receive intellectual and financial support from industry

Align academic research with industry needs

Create and transfer technology that the industry needs now


Today’s Objectives

Provide basic information about the Consortium structure and general plans.

Propose some research areas and topics for your feedback.

Get direction from you on other research topics that are important.

Get direction from you on the overall concepts of the Consortium.


Main Themes

Overlay financial considerations onto the physical system Reservoirs, plants, pipeline, storage Contracts, operational costs, investment costs

Adapt a broader system's view rather than focus on subsystems Coordination across the supply chain Coordination across physical subsystems


Major Research Areas

Monitoring and Surveillance Supply and Demand Management Repair and Maintenance Storage and transportation Design of surface and gas processing facilities

(Sweetening, Gas plants, LNG plants, etc) Science-Based Models in Support of Intelligent Gas

Facility Emissions Regulation Gas Solubility Leak Detection System Maintenance Modeling and Planning
