The stratal architecture of the Mackenzie Basin was reconstructed
based on seismic andwell data and used to define a three-dimensional
model to reconstruct the so-far poorly known thermal and maturation
history of the basin. To correctly account for the complex
tectonic history of the Mackenzie Basin, episodes of uplift and erosion
were implemented based on interpretations of original depositional
surfaces. Our results indicate that the combined effects of
basin inversion and low surface temperatures inhibited maturation
from the late Miocene forward in all except the most deeply buried
parts of the basin. This explains why upper Eocene and younger
deposits aremostly immature despite their burial tomore than 5000m
(16,400 ft). The specific history of the basin is shown to control the
time intervals of potential hydrocarbon generation. Predictions of
transformation ratios using a variety of published kinetics to account
for source rock kinetic variability indicate that potential generation
from Paleocene and older strata occurred mainly before the late
Oligocene. The generation from Eocene strata, however, occurred
mainly during the Miocene and, therefore, is interpreted to be a
source for Oligocene and younger gas-rich reservoirs. These findings
contribute to a better understanding of hydrocarbon systems in the
Mackenzie Basin and are the basis for future studies of hydrocarbon
migration and accumulation.
