Abstract
Disclosed are a system, apparatus, and method for optical fiber well deployment in seismic optical surveying. Embodiments of this disclosure may include methods of deploying a spooled optical fiber distributed sensor into the wellbore integrated in a ballast or weight for a seismic optic tool, to achieve deployment of a lightweight disposable fiber optic cable against the wellbore walls via gravity. The method may further include unspooling the spooled optical fiber distributed sensor and using the optical fiber as a distributed seismic receiver. Once the fiber optic distributed sensor is deployed according to methods of the present disclosure, surveys may be obtained and processed by various methods.
