The technical and technological aspects of commissioning a new intake wells

Investments relating to the opening out of groundwater resources require a rational and responsible approach to their realization as far as technological, economic and also environmental factors are concerned. A correctly intaken aquifer is a warranty of long life of the well, giving possibility to optimize the production parameters, and before all, maintain groundwater resources in good qualitative and quantitative condition. What is most important from an investor’s point of view is the result of geological works, i.e. well ready for production, with properly established production potential and diagnosed technical condition. Determining commissioning conditions of a drilled well should account for the qualitative verifi cation of drilling works and evaluation of its hydraulic effi ciency. All these data create a bases for working out a hydrogeological documentation on the basis of which the resources are established. The use of new diagnostic technologies considerably facilitates the qualitative evaluation of drilling and justifi es the need of performing additional repairs or enhancements. The activation jobs of newly drilled wells are frequently omitted in the plans of geological works (apart from clean-up pumping), despite the fact that drilling technologies frequently include this element [1, 2, 10]. As a consequence, contractors are not obliged to perform them and the activation itself is treated as additional cost which has not been included in the budget. Therefore in most cases both the contractor and the investor tend to omit this procedure.
