A multilateral access system for a multilateral well including a main well bore and at least one lateral well bore includes a tubular workstring having an inner string and an outer string. The outer string includes a diverter body having a cylindrical housing with a lateral window, the diverter body being shaped and dimensioned to direct the inner string the lateral window and into the at least one lateral well bore. The system is used by positioning the tubular workstring within a multilateral bore. The method further includes positioning the diverter body such that the window of the diverter body faces a milled casing window of the lateral well bore and moving the inner string upwardly above the diverter body. Subsequently, the inner string is lowered back though the diverter body, wherein the diverter body exerts a lateral force on a lower end of the inner string urging the lower end of the inner string toward the milled casing window.

Method and apparatus for multilateral construction and intervention of a well

A technique that is usable with a well includes running string that includes a tool and a flowable object that is held in a retained position within the string downhole in the well. After the string is run downhole in the well, the flowable object is released to permit the object to flow in and subsequently seat in a flow path of the string to impede fluid communication so that the tool may be actuated in response to the impeded fluid communication.
