Measured versus predicted vitrinite reflectance from Scotian Basin wells



Measured versus predicted vitrinite reflectance from Scotian Basin wells



ACS Symposium Series 570(Pages 230-248



Model predicted vitrinite reflectance data are calibrated with measured reflectance profiles for wells in the Scotian Basin, Eastern Canada. The predicted data were derived using a basin modeling package (BasinMod) which assumed a rifting heat flow at 200 Ma, a variable stretching factor (beta ), and present day heat flow of 42 mW/m (super 2) . Using combined measured and predicted maturity parameters, measured kinetics on selected source rock kerogens (Kerogen Type IIA-IIB and IIB), and a kinetic model, the timing of hydrocarbon generation and migration from various source rocks (especially Type IIA-IIB from the Lower Cretaceous in N. Triumph G-43 and Type IIB from the Upper Jurassic in Venture B-52) are estimated. Variations in maturation profiles are correlated to abnormal heat transfer due to changes in thermal conductivity or the presence of older rocks (closer to rifting). Anomalies in maturation boundaries are attributed to high sedimentation rates and differences in thermal conductivities due to variations in lithology. Lower Cretaceous (Naskapi Member) source rocks generated and migrated oils during the last 25 Ma; Upper Jurassic-Kimmeridgian Type IIB source rocks migrated mainly condensates and gases between 85-50 Ma.
