Abstract: Aspects of the subject technology relate to systems and methods for performing distributed measurements along a wellbore using distributed strain sensing with a distributed fiber optic sensing cable. Systems and methods are provided for utilizing a distributed fiber optic sensing cable connected to a cementing tool to obtain distributed strain sensing data along the wellbore. Distributed strain sensing data is obtained along the wellbore from the distributed fiber optic sensing cable. Distributed measurement pressure data is determined based on the distributed strain sensing data received from the distributed fiber optic sensing cable. A strain value is determined based on the distributed measurement pressure data and the distributed strain sensing data.

Abstract: A method includes obtaining distributed measurements of acoustic energy as a function of time and position downhole. The method also includes deriving acoustic activity values as a function of time and position from the one or more distributed measurements. The method also includes predicting fluid flow for a downhole perforation cluster as a function of time, wherein predicting fluid flow involves a flow prediction model that is a function of perforation cluster geometry, fluid characteristics, and at least one of the acoustic activity values. The method also includes storing or displaying the predicted fluid flow.

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.

Abstract: First fluid flows from a wellbore through a flow assembly and into a casing inserted into the wellbore. An optical cable is arranged on a bobbin attached to a bottom surface of the flow assembly. The optical cable of the flow assembly is released into the flow of the first fluid and is positioned downhole from the flow assembly by the flow of the first fluid. One or more signals are received via the optical cable. A determination is made that an annulus between the casing and a wall of the wellbore is filled with a second fluid based on the one or more signals. Flow of the second fluid is stopped based on the determination.
