DATE

Monday, 28 November 2022

TIME

9:30 AM – 16:30 PM (SAST)

FEE

Delegate R2000 | Student R1000

DURATION

The session is a 1 Day Course

About this event

Borehole imaging tools like the ultrasonic or optical televiewer play an important role in the mining and engineering industry today. As stunning as the images may look like and as easy as it is to fit a sinusoid to an image and create a structure pick, there are many pitfalls waiting for the interpreter.

This workshop aims at explaining the physics behind the logging tools as well as introducing a solid workflow in correctly processing and interpreting borehole images.

 

What will I learn

Course attendees will be introduced to the most common imaging tools used in the industry, their functioning and the data they produce. Questions about when and under which conditions these tools should be used will be addressed. Using real data samples we will develop a best practice workflow covering the steps from data import to the final presentation of corrected structural picks in WellCAD.

At the end of the workshop the attendees will not only have a solid background about imaging tools but will also get an introduction about how to interpret borehole image data in one of the industry’s standard software packages – WellCAD.   

Working Environment

Course attendees will receive a temporary license of WellCAD prior to the workshop along with data samples which can be used during and after the workshop.

www.xcaliburmp.com

Xcalibur Airborne Geophysics is a Pretoria-based South African airborne geophysical company operating world-wide with a second administrative office in Madrid, Spain. We specialize in ultra-high resolution airborne geophysical surveys with our main offering being low-flying fixed-wing gradient magnetic and radiometric surveys. A new fixed-wing electromagnetic (TEM) system on an Air Tractor platform is currently under development and fixed-wing gravity surveys also regularly flown.

Our fleet of aircraft comprises six owned turbine Air Tractors and a PAC-750 with priority access to leased turbine Islanders (BN-2T), and Eurocopter and Jet Ranger helicopters. These all enable data acquisition at the lowest safe ground clearance possible, typically 10m to 40m. The survey height is generally only limited by the height of the vegetation and the presence of man-made features such as power lines, buildings and antennae. Because spatial resolution improves when flight altitude is reduced, low-level data provides significantly more detailed information for kimberlite detection, base and precious metal exploration, structural and lithological mapping and mine planning, while depth of penetration is not compromised.

The Air Tractors are particularly robust and powerful, thus providing excellent rugged terrain draping capability, together with unsurpassed endurance and safety. The twin-turbine Islander aircraft are used mainly for regional gravity, magnetic and radiometric surveys. These aircraft have the capability of operating at low speeds (80 knots) and are ideal for gravity surveys over water for hydrocarbon exploration. Airborne electromagnetic (AEM) surveys will soon be available with our low-flying towed-bird basic off-time XAG-EM system.

VISION OF SAMERDI

“To maximise the returns of South Africa’s mineral wealth through collaborative, sustainable research, development, innovation and implementation of mining technologies in a socially, environmentally and financially responsible manner that is rooted in the wellbeing of local communities and the national economy.”

THE MANDELA MINING PRECINCT,

officially opened on 4 May 2018, provides the opportunity to have a community of researchers working together in the same space on related subjects both from an inter- and intra-organisational perspective.

THE SOUTH AFRICAN MINING EXTRACTION, RESEARCH, DEVELOPMENT AND INNOVATION (SAMERDI) STRATEGY

The SAMERDI Strategy, as an outcome of the Mining Phakisa, provides a roadmap on how to work collectively towards technological solutions that will increase safety and productivity, and reduce costs to ultimately extend the life of mines by:

Improving the competitiveness of the sector and creating new opportunities for South African based companies to operate in areas along the entire value chain; and

Reposition South Africa as the world leader in mining RD&I by building human resource skills, capabilities, and capacities across industry, academia and the science councils, ensuring its sustainability.

The SAMERDI Strategy provides a roadmap on working collectively towards technological solutions that will increase safety and productivity, reduce costs, and ultimately extend the life of mines.

Thus the implementation of the SAMERDI strategy through collaboration and support from researchers (science councils and academia), government depart­ments, mining houses (individually and collectively), and organised labour unions can be the solution to the chal­lenges that beset the mining sector.
