Geophysical Prospecting

CNPC's geophysical prospecting takes the largest share in the international market, and we have more than 160 seismic crews that provide professional services in seismic data acquisition, processing and interpretation throughout the world.

We provide high resolution 2D, 3D, 3D VSP, 4D and multi-wave and multi-component seismic prospecting & acquisition services under various surface conditions of mountainous areas, plains, deserts, jungles, swamps, tidal and shallow water areas and offshore areas. We have successfully executed contracts on seismic data acquisition, processing and interpretation won from Eni S.p.A, Total, Shell, PDVSA, Petronas, Woodside Energy and Norway DNO, etc.

In addition to onshore operating, we actively develop our deep-sea prospecting business, and have established certain capabilities in deep-sea seismic acquisition and data processing. With enhance R&D efforts in core software, core equipment, and key technologies, as well as application of innovative technologies in risk exploration, new areas, and new types of resources, we provide technical support to many major oil and gas discoveries. Our geophysical prospecting become more efficient and automated thanks to the newly developed GeoEast V3.3 software, the fiber-optic-based, ultra-sensitive Distributed Acoustic Sensing (uDAS) seismograph and GPR Ocean Bottom Node (OBN), as well as the improvement and deployment of precise vibroseis, geophysical prospecting UAVs, and all-terrain vehicles.

In 2019, CNPC acquired data of 56,551 kilometers of 2D lines and 102,958 square kilometers of 3D profiles, with the average daily efficiency up by 16% and 18% year-on-year for the onshore 2D and 3D seismic acquisition, respectively.
