ABSTRACT:
A plug container, such as can be used during a cementing operation at an oil or gas well, includes one or more plug holders which seal against a bypass sleeve when the plugs carried in the holders are released to separate columns of fluid pumped into the well. The bypass sleeve is responsive to fluid pressure so that when sufficient fluid pressure is applied to the bypass sleeve, it lifts the plug holder(s) and uncovers one or more cleanout ports in at least one plug holder. The uncovered cleanout port(s) allow residue fluid, such as cement, to flow out of the plug container. The pressurized fluid can be applied through a hose connected to a single structural member of the plug container so that the hose does not need to be disconnected when the remainder of the plug container is being assembled or disassembled.
