Inflatable Packer
Inflatable Packer
Diameter restriction in oil and gas wells is one of the main challenges for the operators performing remedial works such as zonal isolations, tests, treats, and squeeze. They need an equipment to pass through restriction and set in a larger diameter of Open hole or Cased hole.
TMOT has introduced thru-tubing inflatable packer to overcome such challenges via rig less neither operations nor killing the wells refraining the exposure of the pay zone to killing fluids. The tool can be run and set using a standard coiled tubing system. No rotation is required. It can be set using pressure or retrieve by axial movement.
The tool is made from Nitrile based rubbers with steel ribs reinforcements and can be expanded up to 250% of the original size.
Description
Based on Pressure Rating
SD Inflatable Packers (Standard)
- The most economical version available.
- Can be used in well conditions where applied differential pressure is less than 500 psi.
- Tough inflatable element for high elongation and tear resistance.
- SD packers are available in all standard sizes and can be easily run in straddle configurations.
MD Inflatable Packers (Medium Duty)
- Used in well conditions where the applied differential pressure is less than 1000 psi.
- With durable steel reinforced inflation elements.
- An excellent choice for repeated operation.
- The packer element can be easily replaced.
HD Inflatable Packers (Heavy Duty)
- Suitable for well applications requiring high differential pressure up to 5000 psi.
- Can be used for hydro fracturing.
- A long, fully steel reinforced, field replaceable inflation element.
- Can be run and set using various setting mechanism depending on applications and available tools.
