Abstract
A wellbore tool includes a perforating charge adapted to create a tunnel in a subterranean formation upon activation; a propellant that provides a pressure cycle when activated; and a delay device operationally connected to the perforating charge and the propellant to activate the perforating charge and the propellant in a manner to influence a selected wellbore condition.
Claims20
A wellbore tool comprising:
- a perforating charge adapted to create a tunnel in a subterranean formation upon activation;
- a propellant that provides a pressure cycle when activated;
- a first delay device operationally connected to the perforating charge to activate the perforating charge;
- and
- a second delay device operationally connected to the propellant to activate the propellant in a manner to influence a selected wellbore condition.
A method of influencing a wellbore pressure cycle during a wellbore operation, the method comprising the steps of:
- performing a wellbore operation;
- activating a propellant in the wellbore;
- and
- influencing a selected wellbore condition.
A method for performing a wellbore perforating operation comprising the steps of:
- detonating a perforating gun in a wellbore to create a tunnel in a target formation;
- activating a propellant;
- and
- influencing a selected wellbore condition.
