MFH

Mechanical firing head (MFH) is designed for triggering PKO 63-AT, PKO 73-AT, PKO 89-AT, PKO 102-AT, PKO 114-AT perforators deployed in the tubing in vertical and deviated (up to 40˚) wells containing water, oil or other washing fluid.

Features and advantages

  • simple, durable and reliable design;
  • triggering by dropping of a drop bar, compatible with any equipment installed above the head (sludge traps, differential adapters, etc.);
  • can be used after continuous exposure to high pressure and temperature;
  • PEW can be conducted at deep pressure sink with zero hydrostatic pressure (PEW on “dry pipes”).
