When researching objects whose sizes are comparable to the depths at which they are located, situations often arise in which the actual shape and location of the object does not match the shape and size of the object obtained from the results of geophysical studies. The mismatch of the contours of the object leads to the fact that wells laid according to the results of geophysical work do not fall into the object. In such cases, subsoil users are dissatisfied with the results of the work. The mismatch of the contours of the object is due to the fact that the interpretation of measurements takes place in the framework of one-dimensional models or even in the framework of simple transformations. A full three-dimensional interpretation that could solve this problem is difficult due to the small distribution of three-dimensional programs, the huge equivalence of solutions, and the small amount of data collected. What to do in this case? It is necessary to apply methods developed specifically for identifying three-dimensional structures that use only three-dimensional interpretation and collect much more data with a much denser grid of observations. An example of such a method is the method of sounding by vertical currents (VEC). ZVT allows revealing the real contours of objects using a three-dimensional interpretation and a large amount of data collected.
