ABEM WalkTEM Transient Electromagnetic
ABEM WalkTEM transient electromagnetic system provides an intuitive user interface combined with stunning performance, making it a powerful tool for surveys in the geological near-surface. Applications include groundwater and mineral exploration and environmental investigations. Now with a new booster option for even deeper soundings.
The Transient Electromagnetic (TEM) method
The transient electromagnetic method offers good penetration of conductive overburden and is increasingly popular for hydrogeological purposes as well as general geological mapping and mineral exploration. Since there is no requirement for galvanic ground contact, data can be collected in high resistivity surficial zones and in areas covered by ice or exposed rock.
Advanced TEM made easy
ABEM WalkTEM is derived from the airborne SkyTEM helicopter system, sharing the technology. While SkyTEM covers large areas, ABEM WalkTEM offers a more accurate resolution of fine details in geology with the transient electromagnetic method. With a set of predesigned protocols, ABEM WalkTEM quickly switches between different tasks. A variety of transmitter loop sizes provides good scalability for the project at hand.
Data collection is complete in a few minutes
With its unique acquisition technology, ABEM WalkTEM accurately resolves a wider span of signals, covering both deep and more near-surface data in one go, greatly improving field survey efficiency. A high level of integration means less carrying and setup. Powerful onboard processing software takes the guessing out of field surveys as a resistivity layer model can be produced within a minute after a transient electromagnetic measurement has been conducted.
New booster option for even deeper soundings
The new ABEM TX-60 is an optional external booster that further widens the ABEM WalkTEM’s application area. With up to 60 A output current it enables even deeper transient electromagnetic soundings with larger transmitter loops.
