Spillage occurs in one of three ways:
- Changes in the trapping geometry
- Changes in the fluid contact due to hydrodynamics
- Reduction in reservoir volume due to postaccumulation cementation
Petroleum loss across faults is considered spillage, not leakage, because faults are part of the trapping geometry. Petroleum shows in spilled accumulations are usually immobile at relatively constant residual saturation over a thick section of the reservoir, with a paleo-fluid contact located near the base of the residual saturation. Petroleum in structurally spilled accumulations is relatively unaltered; oil in hydrodynamically spilled accumulations, on the other hand, is usually altered.
