SCOPE OF APPLICATION
- 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
FEATURES
- 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
