The use of MFBR ensures the preservation of reservoir properties of the formation and an increase in well productivity. 2002 - 2006 on the territory of the Republic of Tatarstan, more than 200 wells were drilled using the MFBR, patents Nos. 22243984 and 2235750 were obtained, RD-15339.0-009-04 was put into effect. It was found that when a productive formation is opened with flushing with a traditional drilling fluid, the particles of the solid phase are filtered into the pores of the formation, with the formation of a low-permeability zone around the wellbore. At the same time, the permeability indicators deteriorate from 2 to 10 times, and the size of this zone reaches several tens of meters. Disadvantages typical of traditional drilling fluids, such as increased filtration and clogging of the bottomhole zone with drilling fluid filtrate due to high pressure in the wellbore, when using multiphase drilling fluids, are excluded. In contrast to the used drilling fluids, a stabilized gas (air) phase is formed in the MFBR, which creates a clogging shell in the pores of the formation in the near-wellbore zone. The protective layer formed in this way during drilling is a reliable barrier that protects the oil reservoir from the penetration of the liquid and solid phases of the drilling mud. Application area reservoirs with low reservoir properties; reservoirs with high-viscosity oil; depleted and depleted deposits, deposits with low reservoir pressure; reservoir with high clay content.

However, the market is in no hurry to actively gain a foothold above 1300 points on the MICEX against the background of data on the US economy and comments by ECB head Mario Draghi.
