Over 20 years of proven success!

TITAN 24 surveys provide accurate 2D surface to depth  imaging for drill planning.  By imaging multi-parameters to depth you can reduce the number of drill holes required to test and explore the subsurface on your property.

What is TITAN 24?

TITAN 24 is a distributed array-based geophysical system that collects two separate geophysical surveys; DCIP as well as Magnetotelluric (MT).  DCIP provides resistivity and chargeability sections and the MT provides a deeper resistivity section. TITAN 24 is unique for several reasons.  The technology behind TITAN allows the system to sample data very rapidly and measure very small signals. The DCIP data is typically and routinely collected to depths of 500 – 750 m and the MT data is collected to depths of 1500 m and greater. The survey system was introduced to the market in 2000 and has completed over 400 surveys globally including, over 60 minesite surveys.

How it works?

A complete line of connected receivers (24 or more) is deployed in the field. The line length can vary from 700 m to 5000 m depending on the dipole size used for the target and information desired. Typically in the day time an resistivity & induced polarization (DCIP) survey is executed and subsequently an MT survey is completed. If logistics are smooth, the MT is collected during the night. Both surveys  are completed from one line set-up.

Once the system is set up, the current is injected at one side of the survey. (see above left, red dashed ellipse). All of the 24 deployed dipoles simultaneously read the response. After that event is recorded the current is moved up to the next injection point and another reading is taken. This continues throughout the day until the current has reached the other end of the line. As the current moves through the line all dipoles are read , that is, both the ones in front of the injection and those behind. This is one of the many benefits of a 2D TITAN survey as both current leading and current lagging surveys are combined to produce the final result. This bi-directional sampling helps eliminate biased responses that may occur with conventional methods. (see IP presentation below). Following the DCIP survey, the MT survey is then completed. The MT effectively measures 24 MT sites spaced 100 metres (typically). This provides very high resolution MT surveying, which is typically deployed at 500 m spacing or more.

Flexible Survey Designs

Typically, the survey is deployed in a grid of lines. For a DCIP depth of investigation of 750 metres, the line length or “spread” is 2400 m and the dipole or station length is 100 m; for shallower targets the dipole spacing is chosen smaller and the line length shorter( e.g. 50 m dipoles and 1200 m line length), for deeper targets the opposite (e.g. 200 m / 4800 m. Line spacing is dependent on the level of lateral detail required.  In some cases detail is required in the central portion of the line, but depth is also important so the dipole has been variable – tighter spacing in the middle, larger spacing on the ends.  Another option is to add current injections beyond the end of the lines. These provide additional data for the inversion process, resulting in an image with better depth and resolution below the ends of the lines. (see presentation below for example of large dipole spacing and current extensions)
