Booster Bypass Tool

This innovation is the most powerful option for splitting the flow during drilling, completion and workover operations.

Boosting efficiency

Split the flow

Activated by a vinyl ball, a pre-calculated percentage of drilling fluid passes through the tool to the BHA and drill bit below. At the same time, three field-interchangeable jetting nozzles on the side of the tool are directed up-hole to give increased annular fluid velocity, maximised hole cleaning and minimal well bore erosion. The tool can be cycled to provide split flow up to 10 times.

Activation Mechanisms

The Booster Bypass Tool can be activated by different mechanisms:

Standard Ball

Fast Ball

Fast Dart

Standard Ball

Fast Ball

Fast Dart

The simplest and most reliable tool for most applications. To activate the tool, a single vinyl ball is pumped down to the ball seat. Pressure builds which forces the sleeve downward and aligns the inner and outer ports. A clutch and index mechanism locks the inner and outer ports into position. The tool now remains in the open position. To deactivate and close the tool, another single vinyl ball is pumped down to rotate the index mechanism, slide the sleeve upward and close the tool. 

  • Temperature: Up to 260°C or 500°F
  • Density: 1.34sg or 11.2 ppg
  • Fast ball is a much denser activation ball – in comparison to the standard ball – and used in applications where high mud weights and high temperatures occur. This feature allows for a quicker activation of the PBL tool which is especially helpful in situations where there is limited or no circulation.

  • Temperature: up to 260°C or 500°F
  • Density: 2.50sg or 20.9 ppg
  • A heavy dart, which can be used in the highest mud weights, or where mud cannot be circulated – i.e. packedoff situation. Allows activation by gravity drop. It is much faster than a standard ball, which reduces activation time significantly. Descent by gravity only: can be used in wells with a maximum inclination up to 55°. Descent by being pumped down: can be used in wells with a maximum inclination up to 90°.
