PS-112М, PGSP-2, PGSP-3 BORING PERFORATION GUNS

perforation of thin pay beds with bottom water and gas cap
pay zones, where the oil-bearing part is separated from the water-bearing part by a thin fluctuant barrier
selective perforation of thin-layered formations, representing alternating permeable consolidated interlayers
temporary holes in multistring wells for workover operations on recementing of annular space

High selectivity in perforation of complex reservoirs and thin interlayers
reduce oil-water cut when developing fields with close aquifer and minimize gas factor if gas-bearing reservoir is close
Absence of shock prevents damage of casing integrity, cement sheath, and decrease of filtration properties of bottomhole zone
Controlled perforation of casing, cement, formation (recording of motor load current and tool penetration) allows to certificate each perforated channel
