Thru-Tubing
Thru-Tubing Intervention tools and specialized systems. Intervention tools and specialized systems.
Thru-Tubing Beckmans Construction Company Ltd. has a specialized thru tubing intervention division whom are experts in custom made solutions to solve any down-hole problem in oil, gas, water and salt wells, and complete project engineering. Our strength is our flexibility to respond customer needs, and to design tools suitable for any specific problem. Beckmans Construction Company Ltd. design, manufacture and supply well bore tools for the Oil and Gas Industry to provide our customers with efficient, reliable quality products and offer first class performance. The tools are designed to be more than fit for purpose by being easily re-dressed in the field, simple to operate and having extended tool longevity.
Beckmans Construction Company Ltd. has a wide range of tools available 24/7 in our Oman workshop. Our field engineers have many years of experience, which gives them the ability to rapidly, create an imaginary picture of the down-hole problem and come up with the best solution.
Thru-Tubing intervention is increasingly used to service highly deviated, extended reach and horizontal wells which have become the typical well design in today's field development. Beckmans Construction Company Ltd. has developed tools and systems to perform advanced and cost effective thru-tubing intervention operations.
The following operations are typical for coiled tubing or jointed pipe, but by no means limited to: logging, perforating, setting and retrieving plugs, opening and closing sliding sleeve, fishing, removing scale and debris, re-entry drilling, matrix acidizing and acid washing.
- Standard bottom hole assemblies
- Fishing tools
- PDM's and rotational tools
- Impact and fishing tools
- Clean out tools
- Thru-tubing accessories
- Packers and plugs
Thru-Tubing Intervention Tools
Pre-Construction Connectors
The connector provides a way for attaching tools to the Pre-Construction (CT). Beckmans Construction Company Ltd. can offer a range of proprietary and 3rd party supplied connectors for any operation. These are typically attached either by Slip Mechanism, Internal or External “Dimpling” procedure, Roll-on or Quad Pin.
Standard Bottom Hole Assembly (BHA)
A standard BHA would consist of the Connector, Dual Flapper Check Valve, Emergency Disconnect & a Dual Circulation Sub, which gives you the basic well control components, as well as the ability to get out of a stuck situation.
Motor Head Assembly (MHA)
Originally the MHA was developed for Pre-Construction Drilling Operations, so that the components of the Standard MHA could be fitted into one tool, shortening the tool string considerably. Today the MHA is the preferred tool in any CT operation, over individual components, as they are too cumbersome and take up too much of a deployment length.
Drop Ball Hydraulic Disconnect.
The standard disconnect tool of the industry, whereby pins are sheared when applying pressure to a ball pumped through the CT and landing on a seat in the BHA/MHA, shear pressure is adjustable. This allows a safe means of disconnecting from a stuck tool string below the Disconnect, and leaves a standard Internal GS Fish neck in place for later fishing operations.
Dual Flapper Check Valve (DFCV)
DFCV is the industry preferred well control means, but there are other types such as ball, dart and a combination of the two.
Emergency Pull Disconnect.
A tool that can be released just by applying a predetermined Over pull to the CT, thus shearing a set of pins in the tool. This could be used in operations where inserting a ball in CT is impossible, as when Wire line is used in the CT.
Flow Release Disconnect
Another tool developed to disconnect without the use of a drop ball. The tool is fully pressure balanced and activated by flow, not pressure. A secondary set of pins also has to be sheared by Over pull, to avoid premature release.
Heavy Duty Disconnect
A heavy-duty drop ball disconnect developed for CT Drilling, Jarring and other high load operations.
Dual Activated Circulation Sub
A sub that incorporates two sets of circulation ports. Dropping a ball activates one, and shearing pins by applying pressure to the ball on seat. Applying pressure to the CT to burst a preset disc activates the other port. This allows circulation even though the toolstring might be plugged up below the sub. It can also be used to increase annular velocity or reducing wear on a PDM upon completion of an operation.
Fishing Tools
Hydraulic Release Overshot
This is a heavy-duty flow release tool for CT or Jointed Pipe (JP) operations. It is specially designed to catch a variety of standard external fishnecks, and by changing out the bowl & grapple it can easily be converted to a slick OD catch tool.
Snipper Cutting Overshot.
Snipper is a tool by Thru-Tubing Technology specially designed to wash over and catch stuck CT in the well. By applying Overpull to the tool, the “grapples” lodge & cut the CT at the desired depth. The Snipper Overshot can be run with a High Pressure Pack-Off, described later.
Hydraulic Release Spear
This is a heavy-duty flow release tool for CT or JP operations. It is specially designed to catch a variety of standard internal fishnecks, and by changing out the bowl & grapple it can easily be converted to a slick ID catch tool.
Continuous CT Overshot
Basically the same as a Snipper, although equipped with regular gripping grapples that will not necessarily cut the CT, and can also be run with a Pack-Off.
High Pressure Pack-Off
This is designed to be run either with the Snipper or Continuous CT Overshot, to provide a pressure tight seal around the CT to be brought out of the well.
