  1. Germania Unit Rate Forecasting Based on Other Waterflood Pilots in the Spraberry Area

  2. Objectives • To propose the location of new injection wells in the Germania Unit. • To forecast the incremental oil recovery due to waterflooding in other waterflood Pilot area. The rate forecast is applied to Germania Unit for economic purpose.

  3. FUTURE WORK (Last Meeting) • Improve OFM model to get external data from other Database systems, such as ODBC (Microsoft Access, Dwights and PI). • Perform similar tasks for ET O’Daniel Pilot Area • Perform reservoir simulation

  4. Coupling between Injector and Producers • The coupling is taken based on the production response in the on trend and off trend wells during the waterflood period. • This coupling could be used to determine the new location of injection wells.

  5. Germania (Spraberry) Unit Layout • The red line indicates a coupling between an injector and producers and rectangular box indicates the well has available production history. • WIWs #8, 11, and 15 did not have significant effect on surrounding oil production wells. • The production responses obtained from coupling between an injector and producers are parallel to the fracture orientation in NE-SW direction.

  6. Germania (Spraberry) Unit Layout The green ring fence is taken from the O’Daniel Pilot assuming this unit would behaves similar response. The circle mark indicates the proposed injection wells. From the coupling between injection and production shows that the location of proposed injection wells #408A and 10 should be relocated because they are along old injector path. The wells that have shown good waterflood response in the other Pilots are analyzed to determine the incremental oil recovery during waterflooding. The results are applied to Germania Unit for economic purpose.
