A coupling agent for deployment around an optical fiber in a subsurface wellbore, the coupling agent including a curable or non-curable compound that can form into a reversible polymerized gel state located around at least a portion of the optical fiber and there is a gel-optical fiber interface strain gradient that is greater than a wellbore fluid-optical fiber strain gradient. A method of deploying an optical fiber in a fluid path of a subsurface wellbore and introducing a coupling agent in the fluid path.

Coupling agent to enhanced coupling of optical fibers deployed in subsurface wells

Distributed acoustic sensing (DAS) measurements may be acquired at an observation wellbore during a current stage of a stimulation treatment along a treatment wellbore within a reservoir formation. A cumulative strain trace for the current stage of the stimulation treatment may be determined based on the DAS measurements. Based on the cumulative strain trace, whether or not to adjust a spacing of perforation clusters and/or a stage length used at the treatment wellbore for a subsequent stage of the stimulation treatment may be determined. Responsive to determining to adjust the spacing of the perforation dusters or to adjust the stage length, at least one treatment parameter for the subsequent stage may be adjusted. The subsequent stage may be performed based on the adjusted at least one treatment parameter.
