We show that fiber-optic sensing opens up new possibilities for geophysical measurements with a broad range of applications in well logging and seismic exploration and monitoring. The landscape of geophysical and optical cables is shaped by several key forces: Technological Innovation: Advances in fiber optics, materials science, and cable design enhance performance, durability, and data capacity.

We present a systematic approach to optimize distributed acoustic sensing (DAS) fibre-optic cable layouts using global optimization techniques. Our method represents cable geometries using splines, enabling efficient exploration of layouts while respecting physical deployment constraints. To address this limitation, we propose a distributed helically wound cable (HWC).
