Key words: balanced drilling, “micro-flux” control technology, backpressure, choke manifold, backpressure pump.
Expansion of drilling in complex geological environments calls for further improvement of well drilling and balancing technologies, i.e. technologies to keep the downhole pressure equal or almost equal to the formation pressure. Today, one of the advanced methods of well monitoring is the “micro-flux” control technology that on an ongoing basis compares the volumes of fluid pumped in and flowing out of the well. This automatically performed comparison of drilling mud volumes allows to regulate backpressure and restore the balance in the event that a fault occurs.
