1. Introduction and History of the use of Pressure Data in Exploration.
2. Sources of pressures and salinity data
a) DSTs - Drillstem Tests
b) Production Tests
c) RFTs - Wireline Tests
3. Screening the data
-
How to obtain valid stable pressures from the data
-
How to distinguish mud filtrate from true formation water
-
How to determine correct subsurface fluid gradients
4. Using pressure / depth graphs to correlate reservoirs (are zones continuous or separate?)
5. How to predict gas/oil/water contacts downdip from new discovery wells.
6. How to make Potentiometric Surface and Pressure Maps.
7. How to find permeability barriers (Stratigraphic traps) from pressure drops in the reservoir.
8. Identifying areas of updip and downdip flow.
9. Tilled oil/water contacts
10. Capillary pressures
11. Identifying "Flushed" areas
12. Hydrodynamic traps (accumulations without any apparent seal)
13. Causes of Pressure Anomalies - Underpressure and Geopressure.
14. Using chemical water analysis to correlate zones - Stiff Diagrams
15. Effect of hydrodynamics on unconformity type traps
16. Modern Concepts - Pressure Compartments
17. Estimate times of migration from saturation pressures of pools
18. Integrating hydrodynamics with differential entrapment/migration pathways
