Loss of drilling fluid is a downhole complication characterized by complete or partial loss of circulation of the drilling fluid during drilling.
Factors affecting the occurrence of lost circulation can be divided into two groups:
1) geological factors - the type of absorbing formation, its thickness and depth, insufficient resistance of rocks to hydraulic fracturing, formation pressure and characteristics of the formation fluid, as well as the presence of other accompanying complications;
2) technological factors - the quantity and quality of the drilling mud pumped to the well, the method of drilling, the speed of the round-trip operations, etc .; this group also includes technical equipment and organization of the drilling process.
