The emergence of deepwater drilling is adding more complexity in unknown fields. Deepwater wells are also much more expensive while facing increasingly complex challenges. The Schlumberger seismic-while-drilling technology provides borehole seismic data while the well is being drilled, which enables accurate time-to-depth conversion of surface seismic data without uncertainty on formation velocity down to the drill bit location. Measurements acquired using this technology offer a unique look-ahead capability without disrupting operations, which provides indications of the structures of reflecting horizons ahead of the bit to support drilling and well construction decisions.
