Additional equipment

Mechanical impact head	Hydraulic impact head	Hydro-mechanical impact head	Mechanical impact head with automatic release	Sliding unit with device for mechanical dropping of perforators to bottom-hole

Features: easy to assemble, operating convenience Application field: vertical and directional (up to 40° inclination). Used with: HNS-Percussion initiator detonator	Features: developed in three modifications differing by operation conditions – ventilating, non-ventilating and circulating. Application field: directional and horizontal wells where use of the drop bar is not possible. Also used as backup initiating system Used with: HNS-Percussion initiator detonator	Features: safe to use. An additional min. 7 mPa hydrostatic pressure along with mechanical impact on detonator is required for its initiation. Application field: vertical and directional (up to 40° inclination). Used with: HNS-Percussion initiator detonator	Features: realizes automatic dropping of perforators after firing Application field: vertical and directional (up to 40° inclination). Used with: HNS-Percussion initiator detonator	Features: drops perforator to bottom hole using mechanical method. Application field: vertical and directional (up to 40° inclination).

Filling-up flowing adapter (cuttings trap)	Pressure equalizing adapter	Hydro-mechanical impact head	Circulating adapter	Drop bars

Features: works as a barrier preventing cuttings sinking on the impact head. Application field: used in assembly with INNICOR impact heads. Placed minimum 9 m above the impact head.	Features: contains breaking pin. When drop bar or logging device passes through it, the pin is broken and pressure difference between tubing cavity and hole annulus is equalized. Application field: pressure equalizing between tubing cavity and hole annulus when assembling with packer.	Features: contains hermetic ceramic disc withstanding pressure difference up to 68 mPa from convex side. Application field: mostly used for creation of pressure drop-down when perforating with packer. Also can serve as a cutting trap.	Features: contains breaking pin. When drop bar or logging device passes through it, the pin is broken and the circulation between tubing cavity and hole annulus begins. Application field: when perforating under drawdown, opens circulation between tubing cavity and hole annulus.	Features: developed in three modifications - standard (for standard applications), brass (high duty, with brass bolt at the end) and roller (for initiating in directional wells with inclination from 40° to 60° degrees). Application field: intended for mechanical activation of perforating systems lowered with production tubing.
