Title: Shallow mantle convection beneath West Africa and source to sink at continental margins: A novel approach to reservoir prediction in offshore deep-water settings

Presenter: Dr Bhavik Harish Lodhia (UNSW)

Abstract:

Deep-water settings are prevalent in many of the world’s frontier basins. To better focus exploration spend in today’s challenging environment and predict reservoirs, a novel approach to close the loop between onshore denudation and offshore sediment deposition is required. Sedimentary flux measurements, regional subsidence patterns, tomographic models and simple isostatic calculations are combined to constrain the history of offshore solid sedimentary flux and sub-plate support of the Mauritanian Basin. We combine seismic reflection and well data along the West African margin with shear wave tomography and the uplift and magmatic history of the Cape Verde Rise to constrain thermal, spatial and temporal scales of upper mantle convection. Predictions of solid sedimentary flux to the Mauritanian Basin calculated by inversion of continental drainage are compared to observations in the Chinguetti field of the Mauritanian Basin.

Bio: Bhavik moved to Australia from the United Kingdom earlier this year and is currently a Postdoctoral Fellow in Energy Technology and Geophysics at UNSW. Bhavik graduated with a PhD in Geology and Geophysics at Imperial College London in 2019 and completed a masters/bachelors degree in Earth Sciences at St. Anne's College, University of Oxford in 2014. His work has focused on basin dynamics, geodynamics, sediment source to sink and petroleum systems modelling.
