Video inspection in wells

Inspectia puturilor cu ajutorul unui sistem de inspectie video verticala

Since a water well is often a big investment, a well problem can seriously interfere operations, causing a costly and untimely shutdown and requiring emergency action.

In order to determine the actual condition of the water well, a regular downhole video survey is the appropriate first move.

This tells you what the problem is, where the problem is and helps to determine the proper recovery technique, leading to efficient solutions and significant cost savings.
