Mineral incrustations and bacteria analysis (WSE USA)

Mineral and bacteria incrustations in pipes and well walls can plug and collapse water wells. Preventive detection and analysis allow early diagnosis and specific treatment to inhibit this development. There are several ways (mechanic and chemical) to remove and/or inhibit incrustation, which choice depends on source and sediment nature, so analysis are critical issues to efficiently solve each specific case.

Electrical Resistivity Tomography (ERT) 2D and 3D

The Electrical Resistivity Tomography (ERT) allows obtaining 2D sections and 3D models for the subsoil resistivity distribution. The difference with the related and simpler VES technique is the much higher measurements density and the 2D/3D algorithms to model and interpret data.
ERT is a contact method which uses a set of several electrodes installed on the surface along a profile (2D) or according a regular mesh (3D). Direct current injection into subsoil through pairs of electrodes allows voltage measurements between other electrodes pairs. A switching device, configured according specific protocols, automatically performs all the possible combination, of injection and voltage electrodes pairs, resulting in high density data laterally as well as with depth. This data set allows a detailed reconnaissance of the subsoil electrical resistivity distribution.
