Hydrofracturing

Hydrofracturing is a common and effective means to increase the yield of water wells. Hydrofracturing is a process in which water is pressured into the formation, to open cracks and crevices in the rock, so that water can more readily flow toward the well bore.

Inflatable packers are used to isolate the applied pressure to specific areas of the well bore. Packers may be used singly or in tandem to accomplish this goal. Typically 1,000 to 2,500 psi is required to fracture a well with flow rates varying between 25 to 150 gallons per minute.

For hydrofracturing (6" borehole), TAM manufactures a special 4.75" O.D. inflation element. For part numbers, dimensional and working pressure data and HD inflatable packers please see the element selection. It is designed to be run numerous times without redressing or repair and possesses numerous performance advantages.

To extend service life, the 4.75" O.D. inflation element utilizes a steel cable reinforcement laid on a bias to the tool axis. The cable reinforcement is wound in both directions for the entire length of the element and secured to the tooling connections. Nitrile rubber with special reinforcement in the stress areas forms both the outer seal and bladder parts. The nitrile rubber’s high elasticity characteristics ensure a fast return to original shape when deflated.

Features:

• Durable design for repeated sets - Customers have reported that as many as 600 sets have been recorded with the inflation element continuing to function normally.
• Fast inflation and deflation - set and deflate in less than a minute.
• Well Suited for high pressure - Hydrofracturing to pressures of 3900 PSI (269 BAR) can be achieved in a 6" bore hole. Refer to HD inflatable packers for part number and ordering information.
• Low volume inflation requirements - Volume of inflation fluid required per packer in a 6" bore hole 2.2 gallons or 8.5 liters.
• Easy to operate.
