The WellEnTech Section Mill is designed to mill sections of casing for ; Sidetracking, gravel packing, and/or perforation zones. The Section Mills are available in a variety of OD sizes. The tungsten carbide blades are designed so that all blades will mill simultaneously. The interchangeable Stabiliser Sleeve can be swapped out to suit specific casing weights.

  • Robust construction
  • Tungsten Carbide Insert dressed blades
  • Interchangeable stabilizer sleeve
  • Flotel device Easily redressed
Application
  • Casing milling
  • Perforation zones
  • Scale/Cement removal
  • Pipe Cutting
Operation

The WellEnTech Section Mill is operated by flow through the tool. At a predetermined flow rate, a piston moves down within the tool which pushes all of the section milling blades out of the body. The Section Mill is rotated via a top drive or a down hole motor and the tungsten carbide dressed blades can then mill the target casing. The tool can be supplied with a flotel device which signals the driller than the arms are all fully open. On completion of the milling operation, flow is stopped and the piston will retract by means of a powerful spring allowing the blades to return within the main body of the tool.

The WellEnTech Hydro-set Retrievable Packer is an anchoring and sealing device designed to suit a range of tubing and casing sizes. The packer design includes an integral setting mechanism which negates the need for any additional running and setting tools. The packer is set with the application of tubing pressure and released with a straight pull load.

The WellEnTech Hydro-set Retrievable Packer is ideally suited to whipstock operations where the ability to withstand high axial and torsional loads is required. The slips are designed to spread the setting load evenly across the casing or tubing ID and are hardened to ensure the teeth bite and hold the packer firmly within the casing when subjected to axial and rotational loads. It is also designed to withstand vibrations induced as a result of milling, such as that experienced during window milling operations.

The release mechanism is isolated from well fluids preventing debris ingress which facilitates reliable and dependable de-activation of the packer. The setting and release loads can be adjusted to suit specific operational requirements.

The WellEnTech Downhole Filter Sub is designed to filter debris from pumped fluids. One or more can be installed in various locations within a drill string or completion. In order to maximise the flow area, the filter is installed within a specially designed housing with an increased bore and a bored back box connection looking up. The filters can be removed, cleaned or replaced after each operation. They are manufactured from Stainless Steel to prevent corrosion and to prolong the service life of the filter. Large ports are included as standard at the top of the filter so that should it become full of debris, circulation past the filter can still take place without the need to stop operations. Various filter size options are available to suit all operational requirements.

]]> Features
  • One piece body design
  • Spring loaded, hardened scraper blades
  • 360° blade coverage
  • Flow channels for debris circulation
  • Easy to redress and replace blades
Applications
  • Well Bore clean out
  • Debris circulation
  • Packer/ Plug setting operations
Operation

The WellEnTech ScrapeTech™ is run in hole as part of a BHA to assist with the removal of debris. The scraper blades cover a range and weight of casing/ tubing and are easily interchanged to suit a specific well bore. The sub can be made up anywhere within the BHA and requires no flow or mechanical manipulation to operate the tool. When the BHA is at the target area to be cleaned, it is recommended to work the tubing string up and down to dislodge any debris. Circulation of fluid through a jetting or ported sub will lift debris to surface.

The WellEnTech JetTech™ is a simple circulation and jetting device which can be opened by dart action to allow jetting of BOP Stacks and Wellheads or other critical areas of the wellbore. The tools flexible design allows series of configuration depending on the operational requirements by use of the Inner sleeve and Activation Dart.

The JetTech™ can be run in two operational modes: First mode, with the ports open, it is possible to install the Activation Dart to ensure 100% of the fluid exits through the port. Second mode, with the ports closed, the Activation Dart can be pumped down to shear the Inner Sleeve and open the ports. The external diameter of the JetTech™ can be configured to customer specification with flush outer diameter, or enlarged to 8”, 10” or 16”. Each port has a Jetting Nozzle to concentrate the jetting action and prevent wash-out of the ports. These are simple to replace when so desired.

]]> Features
  • Multiple jetting nozzles
  • Configurable in two operational modes
Applications
  • Wellbore clean-up and displacements
  • Jetting BOP stacks and wellheads
  • Workover/ Intervention
Operation

The WellEnTech JetTech™ is typically run to the BOP stack and can be activated by Activation Dart or run in the open position. To open using the Activation Dart, drop the dart into the string and pump down in a controlled manner. Once the dart lands on the Inner Sleeve, slowly increase pressure until the shear is seen.

Commence jetting at 10 BPM across the stack and wellhead. Reduce to 5 BPM across the annular rams. Function the pipe rams and variable rams to help dislodge debris. Rotate slowly which reciprocating slowly across 1 stand 3 passes

The WellEnTech Boot Basket is designed to remove debris too heavy to be circulated out of the well bore. The robust welded construction ensures the tool strength is optimised. They are manufactured from high-strength heat treated alloy steel, Heavy-duty ribs are attached to the cup to prevent it from being crushed and to guide the tool through tight spots while tripping in and out of the hole. These ribs are integral to the main body of the tool, further enhancing its strength.

]]> Features
  • Robust Design
  • Welded construction
  • High Quality Alloy Steel
  • Large Debris Catch Capacity
  • No elastomers or moving parts
Applications
  • Packer/Plug Milling
  • Underreaming
  • Scale Milling
Operation

The WellEnTech Boot Basket is generally run immediately above a drill bit or mill, but can be positioned anywhere as part of a drill string in order to catch debris. The Boot Basket traps junk by suddenly decreasing annular velocity. This decrease occurs after flow passes the larger OD of the boot to reach the smaller OD of the body and top connection, at which point the heavier milled debris drops down into the catcher. The Boot basket can be run in either open hole or inside casing. To capture larger quantities of debris, additional Boot baskets can be deployed as part of the drilling string or Boot Baskets with extended length catchers are also available.

TheWellEnTechPacker Picker is designed to be used in conjunction with a washover shoe or bladed style of packing milling device. This Packer Picker is designed to catch a profile or bottom end of a Packer and prevent the bottom end of the packer falling when the element and slips have been milled. The Latch is free to rotate on the mandrel, which allows the Latch to remain stationary during the milling operation.There is an emergency shear release mechanism enabling the packer picker to be released from the Packer fail to release after milling.

]]> Features
  • Non-rotatingLatch
  • Fully retained Shear Ring
  • Wide range of interchangeable Latch catch diameters
  • Adjustable Shear Release
  • Easily redressed
Applications
  • Retrieval of Drillable Production Packers
Operation

TheWellEnTech Packer Picker is run down through the Packer bore and is spaced out so that the latch is fully out of the bottom of the Packer when the Bladed Mill or Overshot tags the top of the Packer. The Packer Picker is supplied with a dressed Mill Sub to clear any bore obstructions when running into the Packer bore. Once in position, milling of the Packer can commence. Once the desired amount has been milled, the drill string can be picked up, resulting in the latch contacting the bottom of the Packer and enabling the Packer to be retrieved. If however the Packer fails to release, the Packer Picker can be released by applying a predetermined over pull, shearing the Shear Ring and allowing the latch to collapse and pull up through the Packer bore.
