Abstract
Example embodiments of the present disclosure are directed to measurement and control systems and methods of improved spooling accuracy. Specifically, the systems and method disclosed herein provide techniques for accurately monitoring the depth of a sandline in a wellbore through sensing spool rotation, and controlling certain aspects of the spooling and/or producing certain notifications when the depth is above or below a certain threshold. Thus, the spool can be operated with increased diligence when it gets close to the wellhead. In certain example embodiments, the depth of the sandline is measured based at least partially on the number of spool rotations, compensating for decreasing length of sandline per layer of sandline on the spool.
