Abstract
Systems and methods include a mechanical isolation device that comprises a sleeve, which includes a port for fluid flow between an internal bore of the sleeve and an inside of a tubular. A receiver positioned in the internal bore includes a first orifice at a first axial location on the receiver, and a second orifice at a second axial location on the receiver. The second orifice is either aligned or un-aligned with the port of the sleeve. The receiver is slidable within the sleeve to: (i) move the first orifice into alignment with the port and either move the second orifice out of alignment with the port or keep the second orifice out of alignment with the port; and (ii) move the first orifice out of alignment with the port so that a portion of the receiver covers the port to block fluid flow between the internal bore of the sleeve and the port.
