Abstract
A flow assembly is deployed downhole in a casing for a cementing operation. The flow assembly has a spool with an optical cable. As cement is pumped downhole and through the flow assembly, a dart attached to the optical cable on the spool is dragged with the flow of cement. Cement flow is stopped based on signals along the optical cable that the dart is at a desired location downhole.
Claims20
A method comprising:
- providing an optical fiber coiled about a bobbin at a first location in a wellbore in a subsurface formation, wherein a first end of the optical fiber is communicatively coupled to a data processing system;
- pumping a first fluid through the wellbore, wherein a second end of the optical fiber is dragged through the wellbore via the pumped first fluid;
- and
- monitoring, with the data processing system, a first wellbore condition based on a signal transmitted via the optical fiber at least while the optical fiber is dragged through the wellbore.

An apparatus comprising:
- an optical fiber, wherein the optical fiber is coiled about a bobbin at a first location in a wellbore in a subsurface formation, wherein a first end of the optical fiber is communicatively coupled with a data processing system, and wherein a second end of the optical fiber is attached to a drag member;
- a first sensor, wherein the optical fiber comprises the first sensor;
- and
- the data processing system comprising,
- a processor;
- and
- a machine-readable medium having program code executable by the processor to cause the apparatus to,
- receive a first signal from the first sensor via the optical fiber while the optical fiber is being dragged through the wellbore by a first fluid;
- and
- monitor a first wellbore condition based on the first signal.
