Abstract: Methods and systems to initiate downhole operations in a borehole include deploying a first structure at least partially in the borehole, moving a second structure at least partially along the first structure, wherein at least one of the first structure and the second structure is equipped with a sensor and the other of the first and second structure is equipped with a marker detectable by the sensor, detecting a critical event that is related to an interaction of the sensor and the marker, measuring a time-since-critical event, determining a time delay based on the time-since-critical event, transmitting, with a telemetry system, data from the earth's subsurface to the earth's surface indicating that the critical event has been detected, and initiating a downhole operation by using the determined time delay.

Abstract: Systems and methods to perform a downhole operations in a borehole comprising moving, using surface equipment, an inner structure and an outer structure within the borehole, the outer structure equipped with an interaction device and the inner structure configured to be moved relative to the outer structure in a direction parallel to the borehole by the surface equipment, transmitting, by a transmitter, a downlink instruction to the inner structure, and performing an interaction routine with the interaction device in response to the downlink instruction, wherein the interaction routine comprises an interaction at least partially outside of the outer structure to perform the downhole operation.
