The problematic issues concerning modern well drilling technologies

Abstract

Well drilling is the leading technological cycle that makes it possible to carry out prospecting and mining operations within different mineral deposits. Numerous operations as for construction of different industrial and civil purposes are impossible without well drilling technologies. It should be noted that wells are constructed in the rocks differing with their mechanical properties; in addition, those wells vary greatly in their depths. These are the reasons why the construction periods for the majority of wells are rather long-term with the resulting significant deceleration in completing the current operations
