• Short robust construction
• No moving parts
• Multiple flow ports
• Low maintenance design
• Shrouded magnet design

Applications

• Fishing of ferrous metallic components
• Debris circulation

Operation

The Ported Magnet sub is fitted to the bottom of a BHA. It is made up to the tool string with the correct amount of applied torque, as per the threaded connection on the tool. The tool is then run in hole and the ports enable circulation. Once at depth, the flow rate can be increased to circulate debris away from the fish, allowing it to be collected by the magnet and retrieved to surface.

• Short robust construction
• No moving parts
• Multiple flow ports
• Low maintenance design
• Can be redressed after use

Applications

• Obtaining impressions of fish or downhole components
• Debris circulation

Operation

The Lead Impression Block is fitted to the bottom of a BHA. It is made up to the tool string with the correct amount of applied torque, as per the threaded connection on the tool. The tool is then run in hole and the ports enable circulation. Once at target depth, the flow rate can be increased to circulate debris away from the fish. The tool is then run into the fish with either a single jar impact or set down weight, which leaves an indentation on the face of the LIB, which can then be looked at and interpreted when the tool is retrieved to surface.

• Mechanically operated
• High pull loads achievable
• Simple to assemble, redress and operate
• No redress required

Applications

• Catching and pulling slick OD fish

Operation

The WellEnTech C-Type Overshot is a mechanically operated tool. It is easily assembled and requires no flow or pressure to operate. The fish is fed through the bottom end of the tool and through the slip, the slip expands into the housing as the fish moves up into the bore. The slip allows the fish to slide up into the tool bore and grips the fish if pulled against the taper in the housing. The gradually tapering bore produces a uniform load area on the fish OD reducing the likely hood of collapsing the fish as a result of high pull loads.

• Flow activated
• Enclosed spring design
• Multi-function operation
• Fully adjustable activation pressure
• Easily redressed
• Compact and rugged design
• Interchangeable grapples

Applications

• Standard fishing operations
• Heavy duty fishing operations
• Jetting and pick up operations

Operation

To mechanically function the tool, an axial downward load (in excess of the spring force) enables the grapple to automatically engage the fish. The spring then pushes the grapple back to the supported position, and an applied axial load causes the grapple to bite into the fish, this over pull will verify engagement with the fish.

To release, fluid flow through a nozzle fitted to the nose of the stem creates an internal pressure which pumps the grapple back to the de-supported position enabling the grapple to be pulled free from the fish. The pressure at which activation occurs is adjusted by simply changing out the nozzle orifice dia.

Applications

• Standard fishing operations

Operation

To mechanically function the tool, an axial downward load (in excess of the spring force) enables the Grapple to automatically engage the fish. The Spring then pushes the Grapple back to the supported position and an applied axial load causes the Grapple to become supported by the Main Body. This over pull will verify engagement with the fish. To release, fluid flow through a Nozzle fitted to the nose of the stem creates an internal pressure which pumps the Grapple back to the de-supported position enabling the Grapple to be pulled free from the fish.

Applications

• Standard fishing operations

Operation

To mechanically function the tool, axial load (in excess of the spring force) enables the Grapple to automatically engage the fishing neck profile. Once inside the fishing neck the Spring pushes the Grapple back to the supported position on the Core and an over pull will verify engagement within the profile.

To release, fluid flow through a nozzle fitted to the nose of the Core creates an internal pressure which pumps the Grapple back to the de-supported position enabling the grapple to be pulled free from the profile. The pressure at which activation occurs is adjusted by simply changing out the nozzle orifice dia.

• Short, compact design
• Adjustable shear load
• Torque thru’ design
• Standard internal fishing neck
• Debris tolerant
• Easily redressed

Applications

• Milling operations
• Clean out runs
• Fishing applications
• Baiting operations

Operation

The WellEnTech Straight Pull Disconnect is ideal for operations where the use of a pressure-release disconnect or drop ball-actuated components is not possible. The Tool release load is determined at surface prior to running in hole and is easily adjusted by installing the required amount of calibrated shear screws. The Tool is made up as part of the BHA and run in hole. Should disconnection be required, a pull load in excess of the shear load of the screws will retrieve the upper half of the Straight Pull Disconnect, leaving the lower half in the hole. The standard internal fishing neck can then be engaged with a pulling tool in order to retrieve the lower half of the BHA during subsequent fishing/jarring operations.

• Short, robust design
• High torsional and tensile yield
• Debris tolerant
• Fully adjustable release value
• Burst disc
• Easy to assemble and redress

Applications

• Fishing operations
• Milling, cutting and underreaming operations
• Debris circulation
• Impact Hammer and Heavy Duty Jarring

Operation

The WellEnTech Heavy Duty Disconnect is assembled without the need for any special tools. There are castellation’s in the tool which permit torque transmission. There is a rupture disc (available with a range of rupture pressures) which provides a flow path should a loss of circulation occur. To function the tool a drop ball locates on the release ball seat, applied pressure shears the shear screws, allowing the release piston to move and disconnect the tool. The release piston forces the tool apart without having to apply any axial load. Large flow bypass ports are opened up and circulation is immediately returned to the tool string, providing a surface indication of a positive disconnect. The release piston and drop ball are returned to surface leaving a standard ‘GS’ internal fishing neck for retrieval purposes.
