Thru tubing Equipment

Thru tubing equipment forms a set of tools that are used to perform various treatment or operations on an oil or gas well such as fishing & pulling activities, cutting, connecting & indexing activities, isolation activities, stimulation activities, etc. Some of the types of thru tubing equipment / tools that are used commonly includes:

• Circulating Disconnect – With the help of this tool, the hydrocarbon fluid flows from Circulating Disconnect tool's internal diameter to the annulus. The flow can be disconnected by dropping a ball which is connected to a tool string.
• Dual Circulating Sub – This tool performs the operation of circulating disconnect tool as well as it consists of piston which forces the fluid to pass through on the basis of differential pressure.
• Dual Flapper Check Valve – It is used only when there is a need for adding a unidirectional barrier to bottom hole assembly. The purpose of flappers in this type of check valve is to provide a very high pressure barrier in one direction.
• Dual Flapper Disconnect – It provides functionality of Circulating Disconnect as well as Dual Flapper Check Valve in one tool only. As the name suggest, this tool consists of
  • A circulating disconnect functionality that can be disconnected by dropping a metallic ball.
  • Dual flapper type check valve assembly.
• Coil Connector Full Slip – This tool helps in connecting the end of the tubing coil with the bottom hole assembly.
• Hydraulic Disconnect – This tool operates hydraulically and operations are similar to circulating disconnect tool.
• Motor head Assembly – This tool provides functionalities of Dual Flapper Check Valve, Dual Circulating Sub and a Circulating Disconnect tool and is motor actuated.
