The latest cavern sonar instruments incorporate additional and upgraded sensors to bring our technology up to the highest standards with capability to run accurate deviation, depth correlation to the cemented casing, P/T versus depth
or time, and then to survey the cavern through horizontal and tilted sections, until a mesh of points is built with our engagement to have no unexplored area left.
Whatever the fluid (water, brine, liquid hydrocarbons or gas), whatever the casing conditions (no pipe, one pipe or two pipes), echoes are displayed during the cavern sonar survey with distinctive colors according to their intensity. Thanks to the in-house DimCav processing software, a model of the cavern is computed to determine its shape and characteristics, promptly displayed after the sonar survey in a precise and clear report. The same DimCav software offers various capabilities like superposition of plots, distances to neighboring caverns or to salt limits, and cavern field management.
