Abstract

Systems and methods for cleaning and inspecting a wellbore. A wellbore cleaning tool has a jetting sub-assembly, a reverse circulation sub-assembly, and a guide shoe sub-assembly with a camera. The jetting sub-assembly has jetting nozzles oriented to direct a fluid at the wellbore. The reverse circulation sub-assembly has a barrel defining two inner voids fluidly decouplable from each other. The barrel has a first fluid port. A first set of outlet ports extend through the barrel from the one inner void to outside the wellbore cleaning tool. A second set of outlet ports extend through the barrel from the other inner void to outside the wellbore cleaning tool. The second fluid port controls fluid flow from outside the wellbore cleaning tool and the second inner void. A third fluid port controls fluid flow through the other inner void fluidly to the jetting sub-assembly.
