Development and service of drilling fluid

The interval of 2184-4910 m was drilled with the utilization of polymer-inhibited drilling mud PIBR-2M. Pitless technology was employed. After running the following two sections of Ø 245 mm casing, an interval of 4910-5488 m will be drilled using biopolymer clayless drilling mud Biocar MT.
