University of Oklahoma, Norman, OK 73019Abstract:
With the advances in smart well technology, substantially higher oil recovery can be achieved by intelligently designing the operation scheme in a closed-loop optimization framework. The closed-loop optimization consists of two parts: geological model updating and production optimization. Both of these parts require gradient information to minimize or maximize an objective function: squared data mismatch or the net present value (or other quantities depending on different financial goals), respectively. Alternatively, an ensemble-based method can acquire the gradient information through the correlations provided by the ensemble. Computation in this way is nearly independent of the number of control variables, reservoir simulator and simulation solver. We propose a new method for closed-loop optimization, which combines an ensemble based optimization scheme (EnOpt) with the ensemble Kalman filter (EnKF). The EnKF adjusts the reservoir models to honor observations and propagates the uncertainty in time. EnOpt optimizes the expectation of the net present value based on the updated reservoir models. The combined method is robust, completely adjoint-free and can be readily used with any reservoir simulator. The proposed scheme is illustrated with the Brugge Field test example developed for the SPE-ATW on Closed-Loop Optimization. This test problem has 10 injectors, 20 producers and 3 completion intervals per well that can be controlled independently.Location: Olin Hall of Engineering (OHE) - 122

Tidal Saltwater Wetlands and Coastal Water Quality
Thu, Oct 23, 2008 @ 02:00 PM - 03:00 PM
Sonny Astani Department of Civil and Environmental Engineering
Conferences, Lectures, & Seminars
Abstract:Stanley GrantProfessor of Environmental EngineeringChair, Department of Chemical Engineering and Materials ScienceUniversity of California, IrvineAbstract:Tidal saltwater wetlands are the ocean's last line of defense against polluted surface water runoff from urban watersheds. After entering tidal wetlands, runoff-associated pollutants undergo dilution and transport by what Zimmerman called the "tidal whirlpool", and transformation by myriad physicochemical and biologically mediated processes. Here I present field measurements and modeling studies of fecal indicator (FIB) and nutrients in Newport Bay, Orange County, California. Results from this field and modeling effort shed light on: (1) the maximum volume of runoff a tidal saltwater wetland can receive, above which its pollutant treatment capacity is compromised; (2) design principles for optimizing pollutant treatment in restored tidal saltwater wetlands; and (3) the level of model complexity needed to accurately describe pollutant fate and transport in these complex systems.

Fall Spotlight on Aerospace, Mechanical, and Astronautical Engineering
Thu, Oct 23, 2008 @ 05:00 PM
Viterbi School of Engineering Student Affairs
Workshops & Infosessions
Interested in learning more about Aerospace, Mechanical, and Astronautical Engineering? Come hear from a panel of Viterbi faculty and alumni, industry representatives, and current Viterbi student.Spotlight is a series of workshops held during the fall semester, as part of the First Year Excellence (FYE) and Sophomore Year Connections (SYC) programs. It was created specifically for engineering freshmen and sophomore students who would like to learn more about their programs of study and their departments. Spotlight is a great program for students who are in the process of deciding on a major, or those who may not be certain about the major they have chosen.
Location: Henry Salvatori Computer Science Center (SAL) - 101
