Oilfield services firm Baker Hughes announced Friday the commercial launch of its SeismicTrak seismic-while-drilling service.
The service is designed to provide precise measurements for reducing formation uncertainty, so enabling operators to hit their reservoir targets with greater accuracy. It delivers real-time seismic and waveform data that allows operators to adjust their well trajectory as necessary to avoid potential drilling hazards.
Baker Hughes said that SeismicTrak's ability to detech pressure changes, potential exiting of the reservoir and other downhole uncertainties while drilling allows it to inform operators of approaching formation changes just below the drill bit.
In highly deviated, horizontal, or extended-reach wells, the SeismicTrak service can access boreholes that may be difficult for wireline, reducing the need for additional open-hole time or the use of risky deployment methods. The service collects real-time check-shot data and full wireline-quality vertical seismic profile data in memory for processing after drilling to increase subsurface understanding, Baker Hughes said.
The company also highlighted what it said was SeismicTrak's ability to provide the most-precise time/depth measurement in the industry, with a drift of less than one millisecond over 10 days. Baker Hughes added that its borehole seismic experts will further enhance the service.
