Borehole Magnetic Survey Prices: Understanding Magnetic Surveys for Borehole Development
Magnetic surveys are vital for borehole development in South Africa. They provide insights into subsurface geology, helping identify potential water sources accurately. This is crucial in areas dominated by fractured aquifers.
What is a Magnetic Survey?
A magnetic survey measures variations in the Earth’s magnetic field. It detects magnetic anomalies that might indicate water-bearing rock formations. This method is particularly useful in South Africa, where many wells are nonproductive.
Benefits of Magnetic Surveys in Borehole Planning
Magnetic surveys offer several advantages in borehole planning:
- Improved accuracy in borehole placement
- Increased success rates in water extraction
- Identification of lineaments (24 identified in a recent study, ranging from 150 to 777m in length)
- Estimation of overburden thickness (ranging from 4.41m to 29.4m)
These benefits justify the survey costs. They significantly reduce the risk of drilling unproductive boreholes.
Types of Magnetic Survey Equipment Used
Various equipment types are used in magnetic surveys. The choice of equipment affects survey pricing.
| Equipment Type | Application | Price Range |
|---|---|---|
| Proton Precession Magnetometers | Ground surveys | R50,000 – R150,000 |
| Optically Pumped Magnetometers | Airborne surveys | R200,000 – R500,000 |
| Fluxgate Magnetometers | Borehole logging | R100,000 – R300,000 |
The equipment choice influences magnetic anomaly detection prices. It also affects ground magnetic survey rates. These surveys require investment but are essential for successful groundwater development.
Borehole Magnetic Survey Prices and Cost Factors in South Africa
Magnetic survey costs in South Africa depend on various factors. We’ll examine different survey options and regional price differences. This information will help you choose wisely.
Basic Survey Package Costs
Basic magnetic mapping starts at R2,500. This covers a standard survey depth of about 30 metres. Such depth suits most residential and small-scale agricultural projects.
Advanced Survey Options and Pricing
High-resolution magnetic surveys cost between R10,000 and R25,000 or more. These offer deeper penetration and detailed data for large-scale or complex projects. A 72-hour pump test for irrigation boreholes can cost up to R25,000.
Equipment Rental vs Full-Service Costs
Magnetic survey costs differ between equipment rental and full-service options. Renting might seem cheaper, but professional expertise is crucial. Survey equipment and software cost R800,000 to R3,000,000.
This makes full-service options more practical for most clients.
Regional Price Variations Across Provinces

Provincial Pricing Guide for KwaZulu-Natal and Eastern Cape – Borehole Magnetic Survey Prices
Magnetic survey costs in KwaZulu-Natal and Eastern Cape reflect unique geological conditions and water resource demands. Our price list varies based on location and project scope. KwaZulu-Natal prices are slightly higher due to its diverse terrain.
Eastern Cape’s magnetic survey charges are competitive, especially in areas like Aliwal North. This region offers a mix of urban and rural survey opportunities. The cost per metre is influenced by hot springs, including Aliwal North’s spring with safe thorium levels.
Our pricing considers the diverse needs of these provinces. In KwaZulu-Natal, we offer tailored packages for residential and commercial projects. The Eastern Cape requires specialised survey techniques due to its developed hot springs.
| Province | Basic Survey (per m²) | Advanced Survey (per m²) |
|---|---|---|
| KwaZulu-Natal | R150 | R250 |
| Eastern Cape | R130 | R220 |
For large-scale projects, we offer comprehensive survey packages. These rates consider the project’s complexity and the region’s specific requirements. An example is the solar-powered boreholes project in KwaZulu-Natal.
Technology and Methods Affecting Survey Costs – Borehole Magnetic Survey Prices
New technologies are reshaping magnetic data acquisition costs. UAVs are leading this shift towards more efficient and cost-effective methods. The industry is evolving rapidly, with innovative approaches becoming increasingly popular.
Modern Survey Technologies
UAVs are transforming magnetic surveys. A SibGIS UAV collects 1 line-km of data for R1000, while traditional ground surveys cost R2500. This stark price difference is driving industry-wide changes in magnetic survey equipment rental.
Depth Coverage Options
Modern equipment offers improved depth coverage, influencing survey options. UAVs can operate between 35m to 70m above ground. This range allows for customised surveys based on project needs.
Survey Resolution Levels and Pricing – Borehole Magnetic Survey Prices
The resolution of magnetic field measurements directly impacts costs. Higher resolution surveys provide more detailed data but are pricier. UAV surveys can achieve line spacings as narrow as 25m, offering high-resolution results.
| Survey Type | Cost per Line-km | Resolution | Depth Coverage |
|---|---|---|---|
| UAV Survey | R1000 | High (25m line spacing) | 35-70m altitude |
| Traditional Ground Survey | R2500 | Variable | Ground level |
| Fixed-wing UAV (e.g., GeoRanger) | Variable | Medium-High | Up to 10 hours flight time |
Technology advancements are reducing magnetic data acquisition costs. This trend makes comprehensive surveys more accessible for various applications. From mineral exploration to environmental studies, the benefits are far-reaching.
Choosing the Right Survey Package for Your Needs – Borehole Magnetic Survey Prices
Picking the perfect magnetic survey package for your South African borehole project is crucial. Several factors need careful thought. We’ll help you make a smart choice that fits your needs and budget.
Residential vs Commercial Requirements
Magnetic survey coverage differs for residential and commercial projects. A 2D survey often suits home boreholes, covering less area at a lower price.
Commercial projects usually need more extensive 3D magnetic surveys. These cover larger areas and explore deeper, which affects the cost.
Survey Area Coverage Options
Consider the land area you need to survey for your borehole depth. Smaller surveys are quick and cost-effective. Larger areas take more time and resources.
We offer various packages to suit different survey sizes. This ensures you get necessary data without extra expenses.
Time Requirements and Scheduling
Survey duration impacts cost and project timelines. Factors like terrain access and investigation depth affect the time needed.
We work with clients to optimise scheduling, balancing urgency and cost-effectiveness. A well-planned survey can save time and money by pinpointing the best borehole spots.
