A fracturing and gravel packing tool has features that prevent well swabbing when the tool is picked up with respect to a set isolation packer. An upper or multi-acting circulation valve allows switching between the squeeze and circulation positions without risk of closing the low bottom hole pressure ball valve. The multi-acting circulation valve can prevent fluid loss to the formation when being set down with the crossover tool supported or on the reciprocating set down device and the multi-acting circulation valve is closed without risk of closing the wash pipe valve.

Multi-acting circulation valve

A fracturing and gravel packing tool has features that prevent well swabbing when the tool is picked up with respect to a set isolation packer. An upper or multi-acting circulation valve allows switching between the squeeze and circulation positions without risk of closing the low bottom hole pressure ball valve. The low bottom hole pressure ball valve can only be closed with multiple movements in opposed direction that occur after a predetermined force is held for a finite time to allow movement that arms the low bottom hole pressure ball valve. The multi-acting circulation valve can prevent fluid loss to the formation when being set down with the crossover tool supported or on the reciprocating set down device and the multi-acting circulation valve is closed without risk of closing the wash pipe valve.

Fracturing and gravel packing tool with anti-swabbing feature

A fracturing and gravel packing tool has features that prevent well swabbing when the tool is picked up with respect to a set isolation packer. An upper or jet valve allows switching between the squeeze and circulation positions without risk of closing the wash pipe valve. The wash pipe valve can only be closed with multiple movements in opposed direction that occur after a predetermined force is held for a finite time to allow movement that arms the wash pipe valve. The jet valve can prevent fluid loss to the formation when being set down whether the crossover tool is supported on the packer or on the smart collet.

A downhole choke in the form of a sliding sleeve valve operable in a plurality of positions including fully open, fully closed, and positions in between, is disclosed. It features a hydraulic control system that, in one embodiment, provides the motive force to move the sliding sleeve a predetermined amount for a given applied control pressure. Further increments in applied pressure result in further predetermined movements of the sliding sleeve. In another embodiment, the sliding sleeve lands in a series of grooves in the surrounding housing depending on the degree of pressure applied to the control system.
