Downhole clean out tool

A method of cleaning out at least a portion of a wellbore, comprising:

• running a downhole clean out tool into a wellbore on a downhole conveyance that extends in a wellbore from a terranean surface to a subterranean formation, the downhole clean out tool comprising:
• a sub-assembly coupled to the downhole conveyance,
• a housing coupled to the sub-assembly and defining an inner volume, the inner volume comprising a flow path that extends from an uphole end of the housing, through the housing, and to a downhole end of the housing that comprises a fluid inlet, the inner volume comprising a first inner volume portion and a second inner volume portion, the flow path formed by a flow path tube that extends in the inner volume between the uphole end of the housing and the downhole end of the housing,
• a plurality of first flow ports that extends through the housing, each first flow port comprising an outlet oriented towards the downhole end of the housing,
• a seat formed in the housing,
• a flow divider mounted within the flow path tube and configured to fluidly separate the first inner volume portion from the second inner volume portion, the flow divider comprising or forming the seat,
• at least one fluid tube that extends through an annular flow path between the housing and the flow path tube, each of the plurality of first flow ports fluidly coupled to the at least one fluid tube,
• at least one screen positioned in the inner volume, and
• a second flow port that extends through the housing and comprises an outlet oriented towards the uphole end of the housing;
• dropping a member into the wellbore to land on the seat;
• subsequently to the member landing on the seat, diverting a wellbore fluid circulated to the downhole clean out tool through the downhole conveyance from the flow path, through the plurality of first flow ports, to an annulus of the wellbore, to the fluid inlet, and back into the flow path, the diverting comprising:
• diverting the wellbore fluid from the flow path to the at least one fluid tube;
• and
• directing the wellbore fluid from the at least one fluid tube to the plurality of first flow ports and to the annulus of the wellbore;
• catching, with the at least one screen, one or more debris in the flow of the wellbore fluid circulated into the flow path through the fluid inlet;
• and
• directing the flow of the wellbore fluid circulated into the flow path from the fluid inlet into the annulus through the second flow port in an uphole direction.

A bottom hole assembly (BHA), comprising:

• a top sub-assembly configured to couple to a downhole conveyance that extends in a wellbore from a terranean surface to a subterranean formation;
• a bottom sub-assembly comprising a flow inlet configured to receive a flow of a wellbore fluid;
• and
• a downhole clean out tool fluidly coupled to the top and bottom sub-assemblies, the downhole clean out tool comprising:
• a housing coupled to the top and bottom sub-assemblies and defining an inner volume, the inner volume comprising a flow path that extends from an uphole end of the housing in fluid communication with the top sub-assembly, through the housing, and to a downhole end of the housing that comprises a fluid inlet;
• a flow tube external to and separated from the inner volume within a space between the flow path and the housing;
• a first flow port comprising an outlet oriented towards the downhole end of the housing and configured to fluidly couple the flow path to an annulus of the wellbore through the flow tube and through the housing to direct a flow of a wellbore fluid circulated into the housing through the uphole end into the annulus in a downhole direction;
• a flow divider that comprises a seat formed in the housing and configured to receive a member inserted into the wellbore such that the flow of the wellbore fluid is diverted from the flow path, through the flow tube and the first flow port, to the annulus, and to the fluid inlet based on the member seated on the seat;
• at least one screen positioned in the inner volume and configured to catch one or more debris in the flow of the wellbore fluid circulated into the flow path, through the flow inlet of the bottom sub-assembly, and through the fluid inlet;
• and
• a second flow port comprising an outlet oriented towards the uphole end of the housing and configured to fluidly couple the flow path to the annulus of the wellbore through the housing to direct the flow of the wellbore fluid circulated into the flow path through the fluid inlet into the annulus in an uphole direction.
