Basin Modelling
Basin modeling comprises numerical simulations of geologic structures through time, based on physical and chemical reactions. In the petroleum industry basin modeling has already become a widely used tool to evaluate hydrocarbon potential, and it is widely used to determine subsidence and temperature histories. Furthermore it can be applied to remote and unknown areas, where only sparse information is available, as in the Queen Charlotte Basin.
Basin modeling allows explorationists to simulate basin evolution and petroleum generation, expulsion and migration in a physically and geochemically consistent way. Results from basin modeling studies have been used to better understand petroleum systems in and, most important of all, to identify the possibilities and risks concerning new exploration targets.

Saturation
Computed liquid hydrocarbon saturation and expulsion
from Jurassic marine source rocks in the Ghost Creek and Sandilands
formations. Colours refer to liquid saturation which has a maximum
possible value of 98%. Siltstone beds (effective hydrocarbon seals)
are coloured light purple. |
