VOXI Fundamentals – Remote

18 January 2022 @ 8:30 am to 19 January 2022 @ 12:30 pm PST

This course uses hands-on activities to demonstrate key considerations for data preparation, testing acquisition hypotheses with forward modelling, auxiliary parameters for inversion setup, best practices for inversion modelling, and finally exploring the inversion solution space. Participants will have the opportunity to create models during and after the workshop using VOXI Earth Modelling.

Presenter information

Kanita Khaled, Geophysicist at Seequent.

Kanita Khaled is a Professional Geophysicist with experience in the mining, oil and gas resource industries. She obtained a BSc. in Geophysics from the University of Toronto. Kanita had the opportunity to work as an Exploration Geologist for Teranga Gold, operating out of Senegal. Following this, she moved to Kingston, Ontario to work as a Geophysicist in the oil and gas field, practicing micro-seismic geophysics at ESG Solutions.

She then returned to Toronto to take on a role in potential field geophysics as a Geophysical Data Processor at Geotech Airborne Ltd, working with airborne electromagnetic, magnetic, gravity and radiometric data sets. She eventually administered several airborne geophysics projects in a Geophysicist-Project Manager role at Geotech. Kanita is currently a Geophysicist at Seequent, where she works closely with business, sales, marketing and technical teams to provide high quality solutions for geoscience professionals.
