About This Event

This workshop will showcase the SimPEG open-source project, where researchers worldwide are developing a unified Python framework for geophysical modelling and inversion. Participants will work with multiple geophysical datasets and utilize the current SimPEG capabilities with Geoscience ANALYST Pro Geophysics.

What I Will Learn

Participants will acquire basic skills for data import and preprocessing, creation of EM data objects, setting of data uncertainties, creation of octree meshes, and running the SimPEG modelling and inversion codes.

Prerequisites Required

Knowledge of Geoscience ANALYST is preferred but not necessarily required.

What Should I Bring

Participants will be required to bring a Windows-based laptop with Geoscience ANALYST installed. Training licenses for Geoscience ANALYST Pro Geophysics will be provided to attendees. Software should be installed and tested prior to attending the workshop. Installation links and instructions will be provided closer to the date.

Debmarine Namibia is Namibia’s leading marine diamond mining company and is a recognised world leader in marine diamond exploration and mining technology. Namibia has the richest known marine diamond deposits in the world. In 2005, marine diamond production in Namibia surpassed land based production. Marine recovery is gaining momentum globally, and the prospects of our resource and operations remains positive. Our fleet of vessels fitted with state of the art marine diamond recovery technology operate on a continuous basis and carry enough supplies to operate independently for two months at sea. On board power generation and desalination produce energy and water for the crew, equipment and vessel. In port maintenance and the upgrade of vessel technology takes place every two to three year. Each vessel is operated by a crew of 60-80 people and supported by helicopter operations that provide emergency access and transport for personnel, diamond and additional equipment or suppliers. Crew are on board for 28 days at a time, working a 12 hour rotational shift, before being transported back to land for 28 days of leave.

Bell Geospace has been at the forefront of Gravity Gradiometry for over 30 years. Bell Geospace provides exploration companies with Full Tensor Gravity Gradiometry (FTG) and magnetic data to enhance sub-surface models and de-risk exploration projects.

Explore Province to Play, Efficiently
Airborne geophysics with FTG allows fast screening and ranking of prospective areas at the province and district scale, de-risking ground exploration at prospect and play scale. Accurate and informative data enhances existing complementary data and fine tunes a strategy for future acquisition.

African Gold Exploration
Bell Geo's FTG, gravity and magnetic data acquisition technology is especially good at locating contact zones and faults, suitable for finding the mineralized geology which hosts gold. Bell Geo’s most recent gold exploration project took place in West Africa. Gaud Pouliquen and Colm Murphy can share more details about this in person at SAGA.
Energy-Metals Exploration in Africa
Geoscientific methods are more critical than ever for energy-supply sustainability. Structural and lithological information to demystify subsurface mineral systems is required on a new, larger scale. If you're exploring in the Kalahari and Zambian copper belt, ask us at SAGA about Bell Geo’s experience in Botswana, Zambia, South Africa... and beyond.

New Interpretation Methods
The mines of tomorrow are hidden beneath layers of sedimentary cover or nestled as subtle extensions to known deposits. While traditional airborne geophysics excel in detecting metal deposits near the surface, they struggle when encountering deeper targets or non-magnetic geological trends.

Exploration teams seek to deploy high-resolution technologies on surveys with closely spaced lines or stations covering extensive areas. These surveys should capture a broad signal bandwidth to map the deeper extensions and connectivity with shallow structures effectively. However, such practices are not always feasible due to challenging terrain, including water bodies, vegetation, restricted access, or the significant time and budget required to acquire such data across large areas. Bell Geospace's FTG technology overcomes many of these limitations. With our latest workflows, signal bandwidth resolves shallow complexity and allows confident mapping at depth and will deliver geological structures and shapes within a given depth interval/window.
