Hydrodynamics Class Exercises
STUDENTS START WITH RAW DATA AND PROGRESS THROUGH ALL STEPS TO COMPLETED MAPS
1. Defining a Stratigraphic Trap (800 MMBBL Oilfield), North Alberta.
-
A reservoir pressure/continuity map is made to define major sand pinchout edge. Raw pressure/fluid data prior to discovery is used.
-
It will be shown how the oilfield could have been initially missed due to a false pressure from an old DST.
-
Students will predict extent of field from the discovery DST pressure to decide land acquisition strategy.
2. Identifying Flushed Vs. Prospective Areas in Saskatchewan.
-
Students evaluate regional potentiometric surface maps to define flow direction in Winnipegosis, Midale and other zones
-
Broad non-prospective areas of updip flow where small fields occur
-
More prospective areas of localized downdip flow which is the main trapping mechanism for the 600 ft. oil column in Steelman and Midale/Weyburn fields
4. Finding Giant But Subtle Gas Reserves (B.C.)
-
Students given a few small isolated (1 Bcf) gas pools with intersperesed "water" tests
-
Gas pressure continuity exercise shows mis-correlation by industry
-
Pools really form one huge accumulation and "water" was filtrate
-
Now over 70 wells drilled with 1 Tcf reserves!
-
Spectacular example of hydrodynamics used as gas finding tool
