Tubing couplings and Re-Entry guides are used to connect tubing joints together in the gas/oil well, Re-entry guides are the first coupling of the tubing string to enter the well and provide a guide the tubing as it is lowered into the earth.
A saw tooth tubing coupling is a type of connector used in oil and gas wells to join two tubing sections together. The coupling features a saw tooth profile on the bottom, which helps to break up any debris or sediment that may be present in the well. This can be particularly useful in wells where blockages or other obstructions may be a problem.
Saw tooth tubing couplings are often used in conjunction with re-entry guides, which serve as the first coupling of the tubing string to enter the well and provide guidance as the tubing is lowered into the earth. Together, these components help to ensure that the tubing can be properly connected and guided into the well, while minimizing the risk of blockages or other issues that could impact well performance.
