Filed:

Jan 10, 2013

Appl. No.:

13/738634

Inventors:

Yen Ting LIN - Los Angeles CA, US
Antonio ORTEGA - Los Angeles CA, US
Tayeb Ayatollahy TAFTI - Los Angeles CA, US
Ira ERSHAGHI - Los Angeles CA, US

Assignee:

University of Southern California - Los Angeles CA

International Classification:

E21B 49/00

US Classification:

702 12, 7315239

Abstract:

A method and system of locating discontinuities in a reservoir are provided. The method includes identifying a plurality of injection and production sites in the reservoir, injecting fluid into selected injection sites in accordance with an injection schedule, monitoring an output at the production sites, determining a time delay between the injection sites and the production sites based on the monitored output, and determining a location of discontinuities based on the determined time delay.

Abstract:

A method and system of characterizing a flow property of a production well site in a reservoir are provided. The method includes identifying a plurality of injection and production well sites in the reservoir; injecting fluid into selected injection well sites in accordance with an injection schedule; monitoring an output at the production well sites; determining a time delay between the selected injection sites and the production sites based on the monitored output using an estimated capacitance model; and characterizing a flow property of a production well site using the time delay and the estimated capacitance model.
