Seismic navigation and positioning system
Accurately deploy equipment for surface seismic applications.
seismicVISION seismic-while-drilling service delivers time-depth-velocity information in real time without disrupting drilling operations, helping you make the best drilling decisions, reduce costs, and improve safety.
The service delivers traditional borehole seismic measurements, including real-time checkshot and interval velocity data, that reduce uncertainty ahead of the bit from several hundred feet—sometimes several thousand. Real-time waveforms can be sent on surface through high-speed MWD telemetry for quality control of downhole data. The real-time waveform resolution and sufficient length allows look-ahead vertical seismic profile (VSP) processing.
Continuous transmission of data through the InterACT global connectivity, collaboration, and information service allows data and consulting experts to provide data quality control, update the target locations, and process look-ahead VSPs while drilling. With this improved navigation, you can
Interval velocities give you the necessary input data to constrain the pore pressure models while drilling and thus optimize mud-weight selection, helping to save unnecessary casings and produce a larger section.
Seismic-while-drilling service successfully performs LWD acquisition in high-pressure ramp environment with zero NPT while eliminating casing section.
Seismic while drilling (SWD) technology was first time being used by Oil and Natural Gas Corporation, ONGC recently, on their Andaman Seas deepwater drilling campaign.
Real-time checkshots and images help geostop hole section and select casing point above carbonate reservoir.
In the Gulf of Mexico, large oil and gas reservoirs are associated with sub-salt structures and are very attractive for potential hydrocarbon reservoirs. In 2009, Pemex pursued drilling a prospective location identified with 3D seismic located in a subsalt structure in the Tertiary formations.
Using proVISION Plus, EcoScope, and StethoScope LWD services provided advanced reservoir evaluation in a deviated well offshore Africa.
