]]> Venturi Jet Junk Basket https://wellentech.ae/product/venturi-jet-junk-basket/ Wed, 06 Oct 2021 13:23:13 +0000 https://wellentech.ae/wordpress/?post_type=product&p=1739 Venturi Jet Junk Basket

The WellEnTech Venturi Jet Junk Basket is a device used for the removal and containment of well bore debris. The tool design which, in effect, vacuums debris from a well bore includes Dual Finger Cages at the bottom end of the assembly to trap debris within the body of the tool and a Filter at the top to prevent the re-circulation of the contained debris. The powerful suction generated can pick up objects such as pulling tool fingers, pins, grapples, screws etc. The tool design incorporates two step threads and is therefore robust enough to have washover shoes fitted to the lower thread.

]]> Features
  • Simple robust construction
  • Interchangeable Nozzles and Filter
  • Dual Finger Cages as standard
  • Low maintenance design
  • Numerous tool configurations and lengths possible
  • Easily redressed
Applications
  • Wellbore clean out runs
  • Sand/fill removal
  • Small object retrieval
Operation

The WellEnTech Venturi Jet Junk Basket is run in hole to the required depth and is operated by flowing down through the tool. The fluid flow through the Nozzles, creates a pressure drop at the exit point immediately downstream of the Nozzle. The fluid down stream then equalises with the fluid exiting from the Nozzles inducing a circulation of fluid through the tool producing a suction effect. The effective suction force can be adjusted by altering the Nozzle sizes which can be achieved without the need to strip the tool. The amount of debris collected is determined by the length of Extensions ran and the size of debris collected is governed by the size of Filter fitted within the tool.

The WellEnTech Pump-Out Check Valve Sub is a device designed to be placed at the end of a tubing string to provide a means of isolating the tubing bore from well fluids until the Pump-Out Sub is activated. The design is particularly suited to velocity strings where the production conduit is coiled tubing. The activation pressure is fully adjustable and the tool is designed so that only the application of tubing pressure will activate the tool. A ball seat within the tool has a stinger which holds open double flapper check valves. These check valves can be activated when required by simply dropping a ball, providing a well barrier when removing the string from the well.  The Pump-Out Check Valve Sub can be attached directly to jointed pipe or to coiled tubing via a suitable connector. It can also be supplied with or without a catcher depending on operational requirements.

  • Compact design
  • Dual barrier design
  • Multi-function operation
  • Maximised through bore
  • Connection to suit tool joint or coil connector
Applications
  • Velocity Strings
  • Injection operations
  • Well Kill or Stimulation applications
Operation

Prior to running in hole, the WellEnTech Pump-Out Check Valve Sub is dressed with the required amount of shear screws. The Sub can then be fitted to the tubing and run in hole to the required depth. A predetermined pressure is then applied to the tubing string, resulting in the Pump Out Plug shearing and dropping into the well bore or catcher, permitting well fluid to circulate up though the tubing in the case of a velocity string application. To activate the check valves, a ball is dropped which shears the stinger which moves out from the check valve bore allowing the Check Valves to close, providing a well barrier for retrieval purposes.

The WellEnTech Back Pressure Valve maintains a column of fluid within a tubing string for operations where there is little or no well pressure. That is, applications where the Hydrostatic pressure within the tubing needs to be higher than the pressure in the annulus. Unlike similar type tools on the market, the WellEnTech Back Pressure Valve can be adjusted to the required pressure setting without the need to strip the tool.

]]> Features
  • Short, compact design
  • Externally adjustable
  • Large pressure activation range
  • Hardened seat and poppet to prolong tool life
  • Easily redressed
Applications
  • Low well pressure operations
  • Gas well applications
  • Underbalance drilling
Operation

The Back Pressure Valve is assembled to a tool string where a column of hydrostatic fluid needs to be maintained within the tubing string. Rotation of the Setting Sleeve adjusts the load produced by the spring stack, thereby changing the required pressure to move the Poppet off of the Poppet Seat. The required setting pressure can be viewed through the milled window in the valve body. Once set, set screws lock the Setting Sleeve in position. At this point any pressure in excess of the set pressure will be vented through the tool bore to the tubing or tool string below. Continued pumping over and above the set pressure permits flow down through the tool until the pumps are stopped and the pressure drops below the set pressure. The tool then resets and is ready to be functioned again any number of times.

]]> Hydraulic Tubing End/Nipple Locator https://wellentech.ae/product/hydraulic-tubing-end-nipple-locator/ Wed, 06 Oct 2021 12:56:49 +0000 https://wellentech.ae/wordpress/?post_type=product&p=1731 Hydraulic Tubing End/Nipple Locator

The WellEnTech Hydraulic Tubing End/Nipple Locator provides a means of locating the end of a tubing string or nipples within a wellbore. The tool is activated by hydraulic pressure. Meaning the dogs are retracted while running in and out of hole thereby reducing drag forces and preventing the dogs from rubbing against the casing wall. The spring loaded Dogs provide a positive indication that the tubing end or nipple has been located.

]]> Features
  • Short, compact design
  • Adjustable indication load
  • Multiple use
  • Interchangeable dogs to suit range of sizes
  • Easily redressed
Applications
  • Nipple location
  • Tubing end location
Operation

The WellEnTech Hydraulic Tubing End/Nipple Locator is deployed as part of a tool string where a tubing nipple or tubing end needs to be located for depth correlation. The tool is run in hole in the collapsed position and is generally run past the assumed position of the nipple or tubing end. Flow through the tool is increased and the pressure generated by the Nozzle pushes the Piston and Mandrel upwards energising the Dogs. The tools string can then be manipulated upwards until an over pull is witnessed. At a predetermined over pull the dog will release from the Nipple or tubing end. Manipulation of the tubing both upwards and downwards will produce the same result, verifying the position of the nipple or tubing End. Once completed, flow is stopped and the dogs are retracted back into the tool.

Operation

The WellEnTech Hydraulic Tubing End/Nipple Locator is deployed as part of a tool string where a tubing nipple or tubing end needs to be located for depth correlation. The tool is run in hole and is generally run past the assumed position of the nipple or tubing end. As the tool string is manipulated both upwards and downwards through the nipple profile an increased pull push load will be witnessed at surface, verifying the position of the nipple. Likewise the tubing end can be correlated when an over pull is witnessed as the tool moves back into the tubing end. If for any reason, the tool becomes stuck in hole, a predetermined over pull will result in the shear screws shearing and de-supporting the dogs. The tool can then be retrieved to surface.
