Course description
Capillarity in Rocks – CIR
This course covers conventional reservoirs.
The course provides detailed knowledge of how capillarity affects hydrocarbon distribution in a reservoir rock, and how the magnitude of capillary forces can be used to deduce valuable information about rock properties including pore throat sizes, pore network geometry, porosity, and permeability. Several in-class exercises reinforce the course learning and provide students with experience using capillary pressure data for reservoir characterization. Exercises will be worked on the computer using spreadsheet software.
For the April virtual session, course hours will be 08:00-12:00 US Central time (GMT - 6:00) on Monday, Wednesday, and Friday over the two week class period.
For the October virtual session, course hours will be 08:00-12:00 Western Australia time (GMT +8:00) on Monday, Wednesday, and Friday over the two week class period.
