A downhole tool for removal of debris from downhole tubulars having an internal wall, comprising:

• a mandrel;
• a screen mounted around said mandrel, defining an annular space there between, said space having an uphole and a downhole end;
• a seal slidably mounted to said mandrel, said seal, when engaging the internal wall of the tubulars, blocking an annular passage defined between said mandrel and the tubulars;
• a valve assembly actuated by relative slidable movement between said mandrel and said seal to selectively close off at least a portion of said annular space;
• said seal is mounted on a seal sleeve, said seal sleeve slidably mounted to said mandrel and further comprises a seat;
• said valve assembly further comprises a valve member on said mandrel selectively movable toward or away from said seat;
• said seal sleeve further comprises at least one opening which is selectively closable to the annular passage;
• said closure of said opening to the annular passage coincides with movement of said valve member away from said seat;
• a closure sleeve connected to said screen for tandem movement therewith, said closure sleeve selectively obstructing said opening as a result of relative movement between said mandrel and said seal sleeve.

A downhole tool for removal of debris from downhole tubulars having an internal wall,

• comprising:
• a mandrel;
• a screen mounted around said mandrel, defining an annular space there between, said space having an uphole and a downhole end;
• a seal slidably mounted to said mandrel, said seal, when engaging the internal wall of the tubulars, blocking an annular passage defined between said mandrel and the tubulars;
• a valve assembly actuated by relative slidable movement between said mandrel and said seal to selectively close off at least a portion of said annular space;
• said seal is initially retracted away from the tubulars upon insertion downhole;
• said seal is mounted on a seal sleeve having a passage there through to selectively allow fluid to pass through said seal sleeve and into said annular space inside said screen, said seal sleeve passage comprising a valve seat;
• said valve assembly comprising a valve member on said mandrel which cooperates with said seat to selectively close off said seal sleeve passage with said seal retracted away from said tubulars during run in, such that well fluids pass in said annular passage outside said screen.

A downhole tool for removal of debris from downhole tubulars having an internal wall, comprising:

• a mandrel;
• a screen mounted around said mandrel, defining an annular space there between, said space having an uphole and a downhole end and is selectively accessible to collect debris;
• a seal mounted to said mandrel and selectively movable between a retracted position where it does not contact the tubulars when said mandrel is advanced in a first direction and an extended position in contact with the tubulars when said mandrel is advanced in a second direction to block an annular passage defined between the mandrel and the tubulars;
• a valve assembly between said mandrel and said seal to selectively close off at least a portion of said annular space.

• said valve assembly further comprises a valve member on said mandrel selectively movable toward or away from said seat;
• said seal sleeve having a passage there through to selectively allow fluid to pass through said seal sleeve and into said annular space inside said screen, said seal sleeve passage comprising said valve seat;
• said valve member cooperates with said seat to selectively close off said seal sleeve passage with said seal retracted away from said tubulars during run in, such that well fluids pass in said annular passage outside said screen.

An apparatus for capturing wellbore debris, comprising:

• a mandrel;
• a screen surrounding said mandrel defining an annular space therebetween, said annular space having an open top end;
• and
• a valve member, said valve member selectively covering said screen to allow debris to pass outside said screen as the mandrel is advanced in a first direction, whereupon when said madrel is moved in a second direction opposite said first direction said screen is exposed by said valve to allow flow with debris into said open top end of said annular space and the debris to be left there as the fluid passes through said screen.

An apparatus for capturing wellbore debris, comprising:

• a mandrel;
• a screen surrounding said mandrel defining an annular space therebetween, said annular space having an open top end;
• and
• a valve member, said valve member selectively covering said screen;
• a flow deflector supported by said mandrel and selectively movable from a relaxed position, where it is out of contact with the wellbore and an expanded position where it is in contact with the wellbore, said flow deflector mounted away from said mandrel so as to provide open access to said annular space.

An apparatus for capturing wellbore debris, comprising:

• a mandrel;
• a screen surrounding said mandrel defining an annular space therebetween, said annular space an open top end;
• and
• a valve member, said valve member selectively covering said screen;
• said valve member comprises a first sleeve having at least one first opening thereon mounted to said screen, and a second sleeve having at least one second opening thereon supported by said mandrel and slidably mounted to said screen.
