Abstract
A propulsion tool for delivering a tubing into a subterranean well for performing a downhole operation includes a tool housing, the tool housing being a tubular shaped member. A connector system is operable to secure the propulsion tool to the tubing. A jet assembly extends from an internal cavity of the tool housing to an outside of the tool housing and is oriented in an uphole direction. A jet inner flow path is located within the tool housing. The jet inner flow path is oriented to selectively direct a flow of fluid from the tubing in a direction towards the jet assembly.

A propulsion tool for delivering a tubing into a subterranean well for performing a downhole operation, the propulsion tool including:
- a tool housing, the tool housing being a tubular shaped member;
- a connector system operable to secure the propulsion tool to the tubing;
- a jet assembly extending from an internal cavity of the tool housing to an outside of the tool housing and oriented in an uphole direction;
- a sleeve assembly located within the tool housing, an outer diameter surface of the sleeve assembly and an inner diameter surface of the tool housing defining an annular shaped portion of a jet inner flow path, the jet inner flow path oriented to selectively direct a flow of fluid from the tubing in a direction towards the jet assembly;
- a treatment system extending between the internal cavity of the tool housing to an outside of the tool housing;
- and
- a ball seat, the ball seat being actionable to move the treatment system from a normal closed position to an open position, defining a treatment flow path for the flow of fluid from the internal cavity of the tool housing to an outside of the tool housing through the treatment system.
A system for delivering a tubing into a subterranean well with a propulsion tool for performing a downhole operation, the system including:
- the propulsion tool secured to a downhole end of the tubing, the propulsion tool having:
- a tool housing, the tool housing being a tubular shaped member;
- a jet assembly extending from an internal cavity of the tool housing to an outside of the tool housing and oriented in an uphole direction;
- a jet inner flow path located within the tool housing, the jet inner flow path selectively providing a fluid flow path from the tubing in a direction towards the jet assembly for a flow of fluids;
- a treatment system extending between the internal cavity of the tool housing to an outside of the tool housing through a sidewall of the tool housing, where the treatment system is selectively operable to define a treatment flow path to direct the flow of fluids into the tubing annulus;
- and
- a ball seat, the ball seat being actionable to move the treatment system from a closed position to an open position, defining the treatment flow path for the flow of fluids into the tubing annulus through the treatment system;
- where
- the tubing extends from an earth's surface into a wellbore of the subterranean well, defining a tubing annulus between an outer diameter surface of the tubing and an inner diameter surface of the wellbore.
A method for delivering a tubing into a subterranean well with a propulsion tool for performing a downhole operation, the method including:
- securing the propulsion tool to a downhole end of the tubing, the propulsion tool having:
- a tool housing, the tool housing being a tubular shaped member;
- a jet assembly extending from an internal cavity of the tool housing to an outside of the tool housing and oriented in an uphole direction;
- and
- a sleeve assembly located within the tool housing, an outer diameter surface of the sleeve assembly and an inner diameter surface of the tool housing defining an annular shaped portion of a jet inner flow, the jet inner flow path selectively providing a fluid flow path from the tubing in a direction towards the jet assembly for a flow of fluids;
- and
- extending the tubing from an earth's surface into a wellbore of the subterranean well, defining a tubing annulus between an outer diameter surface of the tubing and an inner diameter surface of the wellbore;
- where the propulsion tool further includes a treatment system extending between the internal cavity of the tool housing to an outside of the tool housing through a sidewall of the tool housing, the method further including directing the flow of fluids into the tubing annulus through a treatment flow path of the treatment system.
