Get deeper well insights, improved injection and maximize the well productivity through our Tubing Conveyed Perforation Systems. Our TCP system enables you to perforate wells with high temperature and in difficult well conditions. Perforate long intervals and facilitate large gun's usage in the wellbore. Deploy TCP along with drill stem testing system for improved well control.
In order to maximize the performance of the reservoir it is very important to perforate the formation interval with correct gun/charge combination with suitable firing head options.
WellMax provides a range of shaped charges API RP-19B for big hole, good hole, deep penetrating and Super deep penetrating charges to match the requirement of your reservoir.
The various charges also available for different temperature ranges as below
RDX <240 DegF
240 < HMX < 300 DegF
300< HNS < 460 DegF
WellMax provides 4.5” Guns for 7” liners and 9-5/8 Casing to be run as TCP & option of 3-3/8” guns for E-Line or Slick Line conveyed. TCP guns are rated to 10,000 psi. For more information, please see the data sheet or contact us
Firing Heads- WellMax offers Hydraulic Firing Head and Mechanical Firing Head as per the industry practices. The hydraulic firing head is dominantly used globally where string is filled with a liquid cushion however mechanical firing head is more dominantly used when the string has partial cushion. A redundant Firing Head option is also available in order to run a hydraulic and mechanical firing head together at once. Rated to 10000 psi For more information, please see the data sheet or contact us
Gun Release- Automatic gun release is designed to drop a gun string into the rathole immediately after firing. Dropping the gun string immediately after firing has several advantages over deploying slickline shifting tools and pressure activated release tools. These include: avoiding the gun string sanding in when perforating weak sands, allowing efficient post perforation cleanup in permanent completions and eliminating the complications of dropping guns in highly deviated wells.
Mechanical Gun Release is designed to provide an option to drop the guns into the rathole after firing. The release is usually run about 30ft above the guns and below the ported debris sub under the packer. Operation of the release consists of engaging the profile in the latch with a standard slickline Type B shifting tool, jarring upward to shear the latch retainer screws. When the screws shear, the latch moves up allowing the tool to separate, dropping the gun assembly into the rathole and simultaneously releasing the shifting tool.
