Abstract
An assembly configured to be disposed within a well at an intersection of a parent bore of the well and a lateral bore of the well is provided. The assembly includes a junction having a mainbore leg and a lateral leg, as well as a passage in the mainbore leg configured to receive a flowing fluid. A port in the mainbore leg is in fluid communication with the passage such that the flowing fluid in the passage creates a suction at the port to draw debris in the well through the port and into the passage.
Claims17
An assembly configured to be disposed within a well at an intersection of a parent bore of the well and a lateral bore of the well, the assembly comprising:
- a junction comprising:
- a junction body,
- a mainbore leg extending from the junction body, and
- a lateral leg extending from the junction body;
- a passage in the mainbore leg configured to receive a flowing fluid;
- a port in the junction in fluid communication with the passage such that the flowing fluid in the passage creates a suction at the port to draw debris in the well through the port and into the passage;
- and
- a completion deflector positioned in the mainbore of the well, the completion deflector having a deflection surface oriented to allow diversion of the lateral leg into the lateral bore;
- wherein the port is oriented to allow collection of debris from the deflection surface as the mainbore leg is landed in the completion deflector.
An assembly configured to be disposed within a well at an intersection of a parent bore of the well and a lateral bore of the well, the assembly comprising:
- a junction comprising:
- a junction body,
- a mainbore leg extending from the junction body, and
- a lateral leg extending from the junction body;
- a first passage disposed at least partially in the lateral leg;
- a second passage disposed at least partially in the mainbore leg;
- a valve assembly fluidly coupled to the first passage to selectively divert fluid from the first passage to the second passage;
- a collection port in the mainbore leg in fluid communication with the second passage such that fluid flowing in the second passage creates a suction at the collection port to draw debris in the well through the collection port and into the second passage;
- and
- a completion deflector positioned in the mainbore of the well, the completion deflector having a deflection surface oriented to allow diversion of the lateral leg into the lateral bore;
- wherein the collection port is oriented to allow collection of debris from the deflection surface as the mainbore leg is landed in the completion deflector.
A method for completing a well having a mainbore and a lateral bore, the method comprising:
- positioning a junction in the well, the junction comprising a junction body, a mainbore leg extending from the junction body, and a lateral leg extending from the junction body, the mainbore leg having a collection port in fluid communication with a passage in the mainbore leg;
- positioning a completion deflector in the mainbore of the well, the completion deflector having a deflection surface oriented to allow diversion of the lateral leg into the lateral bore;
- flowing fluid through the passage to create a suction at the collection port;
- and
- collecting debris from the deflection surface of the completion deflector through the collection port.
