For land acquisition, different types of sources may be used depending on the acquisition settings. Explosive sources such as dynamite are the preferred seismic sources in rough terrains, in areas with high topographic variability or in environmentally sensitive areas e.g. marshes, farming fields, mountainous regions etc. [4] Such type of sources needs to be buried (coupled) into the ground in ...
Acquisition Services: ION offered equipment and software for seismic data acquisition. This included specialized tools for synchronizing seismic sources. Processing Services: The company processed seismic data to generate high-resolution images of the subsurface of Earth. These images were crucial for exploration, exploitation, and production ...
OGDCL utilizes seismic as the primary imaging technology for exploration of hydrocarbons. It currently operates five seismic acquisition crews, capable of acquiring 2D/3D data in diversified terrains. It also operates seismic data processing center to handle advanced image processing. [12]
TGS, formerly TGS NOPEC Geophysical Company ASA [2] is an energy data and analytics company. It gathers, interprets, and markets seismic and geophysical data regarding subsurface terrains worldwide in order to evaluate oil and gas formations for drilling operations. [3]
Recently, the availability of inexpensive, high-quality 3D seismic data (from reflection seismology) and data from various electromagnetic geophysical techniques (such as magnetotellurics) has greatly aided the accuracy of such interpretation. The following section discusses these elements in brief.
Shell Processing Support data format was initially defined and used by Shell Internationale Petroleum for transferring of seismic and positioning data to the processing centres. In 1993 SEG Technical standards committee on ancillary data formats adopted SPS as the standard format for exchanging Geophysical positioning data.
A seismic source is a device that generates controlled seismic energy used to perform both reflection and refraction seismic surveys. A seismic source can be simple, such as dynamite , or it can use more sophisticated technology, such as a specialized air gun.
His first job was in Houston, working as a geophysicist processing seismic data for Western Geophysical, a 3-D seismic services firm. Then he became an exploration geophysicist and spent six years working for Rosewood Resources , an independent oil and gas exploration company.
