By integrating cutting-edge seismic acquisition and imaging technology with our own proprietary geological knowledge, we are gaining unique insights about the subsurface.
Our seismic technologies are improving the quality of the data we gather and helping to drive the exploration, development and production of oil and gas around the globe. Our goal is to obtain the best quality seismic to illuminate hydrocarbon traps and thus optimize the description and characterization of our reservoirs. Gulf of Mexico subsalt imaging: We have a long history in Exploration and Production of oil and gas in deep subsalt reservoirs in the Gulf of Mexico. But success does not come easily. Salt presents significant barriers to seismic penetration and creates complex noise that is extremely difficult to remove from conventional seismic surveys. It takes thoughtful and innovative approaches as well as state-of-the-art technology to obtain the most accurate sub-salt seismic images.
We use the latest in wide azimuth seismic acquisition technology, which addresses some of the illumination issues by recording a wider range of azimuths – horizontal directions – and offsets –the distance between a seismic source and a receiver. This enables us to acquire data from all directions rather than from a single direction as is the case in conventional narrow azimuth seismic acquisition. We also use the latest computational methods and imaging algorithms to create increasingly detailed and accurate pictures of the subsurface. For example, subsalt imaging has transformed the way by which we can “see” deeper and more complex geological structures buried in the subsurface. By combining these innovative seismic technologies with advanced geologic interpretation, we are improving our abilities to discover and develop oil and gas reservoirs in increasingly challenging environments. 4D Seismic:
We are an industry leader in applying 4D seismic to optimize production and maximize recovery from existing fields. For example, we are using an ocean bottom cable monitor system, which records the velocity and pressure signals from multi-sensor cables deployed on the ocean floor. We combine the information from this survey with legacy data from a standard 3D streamer baseline survey, to create detailed 4D or time lapse images. Our use of 4D seismic has allowed us to target bypassed pay zones and identify new untapped fault blocks with a degree of accuracy and consistency that would have been impossible just a few years ago. Seismic imaging for unconventional reservoirs: Our extensive use of 3D seismic has made a significant contribution to the rapid and efficient development of the Bakken formation in North Dakota. We have acquired and will continue to acquire proprietary 3D seismic over most of our key lease holdings in the Bakken. By using the latest wide azimuth acquisition technologies, we have created detailed maps of the subsurface. In turn, we use this data to accurately steer the trajectory of long lateral wells into the most productive zones of the Bakken formation and we are able to identify sweet spots by analyzing state of the art seismic attribute volumes. The seismic methods and techniques we have refined in the Bakken are now being transferred to the Utica Shale play in Ohio.
