Profile: Sercel, Inc. manufactures integrated equipment for hydrocarbon exploration in land, transition zone, ocean-bottom cable, marine and down-hole environments. MaxiWave™ is a 100-level digital downhole seismic array to record vertical seismic profiles (VSP). It can also be used for semi-permanent installation in a fixed position in the well for passive monitoring (hydraulic fracturing mapping or reservoir monitoring) or to record heavy surveys such as 3D VSP & 4D VSP around the well for detailed and time-lapse reservoir imaging. Sentinel® solid streamer is robust. Its solid cable design offers noise performance over fluid-filled sections during periods of marginal weather conditions, thereby extending the data collection window. This uniform solid construction provides crush and impact resistance, skin support against puncture & distributed loading during cable deployment & retrieval.
