Premier Downhole Geophysics
Wireline Africa (Pty) Ltd
With more than 45 years of specialised expertise, Wireline (Pty) Ltd is a leading provider of downhole geophysics and in-situ borehole measurement solutions across Africa. Formerly part of Weatherford, our company pioneered borehole geophysical logging in the mineral and mining sectors and continues to deliver the highest standard of subsurface evaluation.
From the structural logging used to position Gautrain’s foundational support pylons to large-scale resource estimation and geotechnical studies for major mining houses, our work is relied upon where accuracy and geological clarity matter most.
Our Mission
To deliver precise, high-resolution subsurface data that empowers mining, exploration, and engineering teams to make safe, informed, cost-effective decisions.
Our Approach
We combine oilfield-grade technology, purpose-engineered Slimline tools, and advanced processing techniques designed by physicists and geoscientists. This allows us to provide rapid data acquisition, high-quality results, and actionable interpretation across all major mineral fields—including coal, base metals, precious metals, hydrocarbons, and CBM.
Downhole Geophysics Experts
Wireline (Pty) Ltd is a leader in borehole geophysics and in-situ geological measurement, with over four decades of experience across Africa. From structural logging for Gautrain to advanced mineral exploration, our data-driven insights support mine design, resource estimation, and geotechnical analysis.
What We Do
We deliver high-resolution downhole measurements that reveal:
- Lithology and porosity
- Faults, fractures, and stress orientation
- Rock strength and mechanical properties
- Water levels, flow, and well temperature
- Coal quality and seam boundaries
Our technology supports everything from coal and base-metal mining to oil, gas, and CBM exploration.
Our Specialized Tools
- Dual Density & Neutron Sondes – Identify rock composition, porosity, and coal quality.
- Resistivity & Flowmeter Tools – Measure conductivity, temperature, and fluid movement.
- Sonic & Acoustic Imaging – Reveal fractures, stress zones, and 3D formation visuals.
- Dipmeter & Verticality Systems – Accurately map borehole orientation and depth.
- Blast Hole Logging – Optimize fragmentation and reduce coal loss.
Why Choose Wireline
