Wireline Pressure Control Equipment


The whole sysgtem of wireline pressure control equipment can be divided into 8 individual parts:

Positioned at the uppermost point of the pressure control equipment string, Grease Injection Control Head comprises three major sub-assemblies, Stuffing Box and Line Wiper and the Flotube Assembly.
Features and Benefits:

  • The hydraulic stuffing box is designed to pack-off on a stationary wireline.
  • Maintains a dynamic seal around wireline when a grease injection system is used
  • Prevents escape of wellbore fluids
  • Grease seal is achieved by pumping a viscous fluid between the wireline and flotube
  • Recommended flotube clearance + 0.003" to 0.008".
  • Grease tubes are available in various sizes for slickline & braided line
  • The bottom connection can be mated to a quick-union, or a ball check valve/tool catcher combination.
  • Available in pressure ratings up to 15K

The Tool Catcher is a multiple tool/size, cable head catcher. It is durable, easy to use and simple to maintain. The tool catcher is designed to be fail-safe: it is permanently in the catch position and requires hydraulic pressure to release.
Features and Benefits:

  • "Catches" cable head to prevent loss of tool string
  • Mechanical latch is always in the "Catch" position
  • Multi-catch options are available
  • Tool catchers are available with ratings from 5,000 psi to 15,000 psi WP, STD and H2S service.
  • Tool catchers are available with quick unions top and bottom.
  • As an option the tool catcher is available with a glycol injection port.

Its purpose is to allow the wireline tool string to be raised above the wellhead prior to and after wireline operations, thereby enabling the wellhead valve to be opened and closed, allowing entry and exit from the well bore. The lubricator sections must be long enough to contain the entire tool string.
Features and Benefits:

  • Allows a tool string to be completely contained within the pressure control stack
  • Available with pump-in/bleed-off ports
  • Variety of lengths and options
  • Maximum working pressure 15,000 psi
  • Standard and H2S Service

It prevents the loss of wireline tools downhole in the event of the wire being pulled-off the rope socket, by retaining the dropping tool on a flapper. The flapper has an opening larger than the wireline, but smaller than the tool string.
Features and Benefits:

  • Prevents loss of tool string down hole
  • Installed below lubricator
  • Manual and hydraulically actuated models are available.
  • The tool string may be pulled freely upwards through the tool trap when running a tool in the well by activating the piston in the hydraulic actuator.

Quick Test Sub is inserted either above or below the wireline valve at the position of the joint normally opened to insert and retrieve tools from the well. After performing the first pressure test to check the integrity of whole string, subsequent pressure tests can be made using the Quick Test Sub to verify the integrity of joint disconnected rather than having to test the whole assembly.
Features and Benefits:

  • Designed to increase productivity of multiple run wireline jobs
  • Saves time by eliminating the need to re-pressure test an entire pressure control stack
  • Hydraulic pressure is applied between two O-rings to test the integrity of a broken connection
  • Valve can be closed and operations can continue once the connection passes the pressure test

The valve gives positive protection during well service operations, when operating with slickline, braided wireline and electric line. It is available in a full range of sizes and working pressures, from 2 1/2" to 6.70" bore sizes, and 5,000 psi to 15,000 psi working pressures. Additional sizes are available on request. For greater corrosion resistance all sizes of Wireline Valves can be supplied with XYLAN Coating or Inconel inlays in the ram bores and the through bore.
Features and Benefits:

  • Compact size, allowing shorter rig-up heights
  • Keyless ram bores, allowing ram inversion as and when required
  • Quick coupled hydraulic cylinders, allowing fast removal of cylinder for ram or seal replacement
  • Threaded quick unions, allowing the use of any Elmar, Bowen or Otis quick union without changing the body (integral unions/flanges are available as an optional extra)
  • Ram position indicator rods
  • Equalizing and bleed-off valves installed
  • Hydraulic cylinder support arms for 4" - 6.70" wireline valves
  • Single, double, triple, and quad Wireline Valves are available

A Pump-In-Sub is normally placed below a Wireline Valves. It allows for bleeding off of well gases and fluids from a pressure control stack. The Pump-In-Sub assists in introduction of fluids to a well for well control purposes. It is also used to direct flow away from the pressure control stack.
Features and Benefits:

  • Used for a variety of purposes
  • Bleed-off or pump-in
  • Available in most sizes and pressure ratings
  • Studded or Weco Union side outlet

Wellhead Adapter Flange consists of a quick union machined on a standard API flang. The upper end has a standard quick union and can be supplied with a blanking plug if required. Fountain Petro LLC designs and manufactures Wellhead Adapter Flange for all API standard models.
