Kinley Tubing Perforator

A mechanical tubing punch powered by an optimized propellant capsule which can be operated via slickline or e-line.

The Kinley Tubing Perforator is used to deliver a precise communication port between the production tubing and the annulus. Using a small capsule of propellant, it strikes a mechanical punch through the wall of the pipe, creating a perfectly round hole of the desired diameter.

The punch can be replaced with a self-seating metal orifice to limit the erosive effect of fluids flowing through the hole. Alternatively, a check-valve assembly can be inserted. The checkvalve remains in the wall of the pipe to provide a temporary, controlled injection point for gas lift operations. In either case, there is no damage created beyond the limits of the hole originally punched.

Kinley Sandline Cutter

The Sand Line Cutter is designed to allow the recovery of wireline, slickline and electric line when the attached toolstring is stuck in the well and pulling out of the rope socket may not be possible. It will cut any wireline up to 1 1/8" including control lines, drilling lines and power cables. It can be initiated by a drop bar or an electronic timer. It assembles over the line and is recovered with the cut line.

Using the Sandline Cutter, Seawell provides operators with the option of saving the line in one piece instead of attempting to pull out of the rope socket/cable head or risk breaking the line at the surface. Frequently, the entire cost of the cutting job will be more than offset by the value of the saved line.

Functionally, the line is cut mechanically by a cutting edge driven by a contained explosive force, initiated by an electronic timer rather than a drop bar. With the timer, there is no more guessing whether or not the drop bar has reached the firing pin. The tool is also designed to save a fishing trip by crimping on to the end of the cut line, allowing the cutter to be recovered with the freed line as it is pulled out of the hole.

Key features and benefits of the Kinley Tubing Perforator

• Slickline operated so no requirement for expensive electric line and surface read-out equipment. And virtually any conveyance method available at the wellsite can be used
• Lower threaded connection means that spacers and special profiles can be used to position the instrument with accuracy
• Check-valve insert temporarily substitutes for an expensive gas lift mandrel
• Tungsten carbide ball check valve is very durable and dependable
• Pre-set hole shape & size allows precise calculation of pumping rates, volume and pressure in any circulating application
• Punch pre-set execution effectively avoids damaging the casing
