  • Memory logging system for determining the condition of a sliding sleeve
    Patent number: 7810564
    Abstract: A memory logging system for determining the status of a sliding sleeve valve disposed within the borehole. The sliding sleeve contains signal inducing devices. A logging tool is conveyed through the sliding sleeve and time intervals between sensor excursions induced by the sleeve's signal inducing devices are recorded and stored within the tool memory. These data are subsequently recovered when the tool is returned to the surface of the earth, and sensor excursion data are processed in a surface processor to ascertain relative axial positions of the sliding sleeve outer housing and the insert. The condition of the sliding sleeve is determined from these relative axial positions.
