Session: WS15 – Fiber optics sensing for Vertical Seismic Profile (VSP) surveys
Publication date: 16 June 2014
As part of a CO2 storage project at Citronelle, Alabama, VSP data was acquired with a short string of tubing-deployed, wall-locking, geophones (18 at 15 m spacing) and a long (3 km) fiber, also tubing-deployed. We will show data examples comparing geophone and DAS attributes such as spectral response, signal-to-noise ratio and ground motion sensitivity comparison.
