Andrew S. Long (born 1965) is an Australian geophysicist. He has a PhD in geophysics (1996) from the University of Western Australia, and a post-doctoral term at Stanford University. He is a leader in the application of geophysical technologies to exploration for oil and gas in marine areas, [1] and has written and presented several papers at the Society of Exploration Geophysicists (SEG), the European Association of Geoscientists and Engineers (EAGE), the Australian Society of Exploration Geophysicists (ASEG), the Australian Petroleum Production & Exploration Association (APPEA) and many other international conventions and journals.

Early leader in the application of satellite altimetry technology to the mapping of the marine gravitational field in the early 1990s, [3] the application of modelling methods to 3D seismic survey planning, [4] [5] the development of High-Density 3D (HD3D) [6] [7] [8] technology for seismic exploration, the introduction of Multi-Azimuth and Wide-Azimuth 3D technology into the Asia-Pacific region, [9] the introduction of Dual-Sensor Streamer technology to the oil and gas industry., [10] [11] the development and commercialization of the Multi-Level Source solution for 'broadband' seismic, [12] the development of the Simultaneous Long Offset method for efficiently acquiring ultra-long offset marine seismic surveys, [13] and the adaptation of Separated Wavefield Imaging to improve marine seismic survey efficiency. [14]

He has lectured extensively on the applications of 'broadband' seismic technologies, with particular emphasis upon ultra-low frequency benefits and challenges, providing professional courses on behalf of the EAGE and SEG. Versions of the 2009 Multi-Level Source paper were awarded Best Presentation awards at the Indonesian Petroleum Association (IPA) and SEG annual meetings, and the paper titled Low Frequency Seismic: The Next Revolution in Resolution was awarded Best Presentation at the 2014 annual APPEA meeting.

In 2009 he was honoured as the inaugural Honorary Lecturer [15] for Pacific South for the Society of Exploration Geophysicists, [16] the largest international professional society for the geophysical community.

Reflection seismology Explore subsurface properties with seismology

Reflection seismology is a method of exploration geophysics that uses the principles of seismology to estimate the properties of the Earth's subsurface from reflected seismic waves. The method requires a controlled seismic source of energy, such as dynamite or Tovex blast, a specialized air gun or a seismic vibrator. Reflection seismology is similar to sonar and echolocation. This article is about surface seismic surveys; for vertical seismic profiles, see VSP.

Society of Exploration Geophysicists

The Society of Exploration Geophysicists (SEG) is a learned society dedicated to promoting the science and education of exploration geophysics in particular and geophysics in general. The Society fosters the expert and ethical practice of geophysics in the exploration and development of natural resources, in characterizing the near-surface, and in mitigating earth hazards. As of November 2019, SEG has more than 14,000 members working in more than 114 countries. SEG was founded in 1930 in Houston, Texas but its business office has been headquartered in Tulsa, Oklahoma since the mid-1940s. While most SEG members are involved in exploration for petroleum, SEG members also are involved in application of geophysics methods to mineral exploration as well as environmental and engineering problems, archaeology, and other scientific endeavors. SEG publishes The Leading Edge (TLE), a monthly professional magazine, Geophysics, a peer-reviewed archival publication, and Interpretation, a peer-reviewed journal co-published by SEG and the American Association of Petroleum Geologists.

Nigel Allister Anstey, British geophysicist, has made major contributions to seismic exploration, which are the foundations for many of the techniques used in today’s oil and gas exploration. Anstey’s contributions impact every major area of seismic exploration -– from seismic acquisition to seismic processing to interpretation to research. He is the holder of over 50 multinational patents. He is best known by many geoscientists for distilling the geophysical concepts of the seismic method into non-mathematical teachings for seismic interpreters.

Jon F. Claerbout is an American geophysicist and seismologist. He is the Cecil Green Professor Emeritus of Geophysics at Stanford University. Since the later half of the 20th century, he has been a leading researcher and pioneered the use of computers in processing and filtering seismic exploration data, eventually developing the field of time series analysis and seismic interferometry, modelling the propagation of seismic waves.

Seismic source

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. Seismic sources can provide single pulses or continuous sweeps of energy, generating seismic waves, which travel through a medium such as water or layers of rocks. Some of the waves then reflect and refract and are recorded by receivers, such as geophones or hydrophones.

Seismic migration is the process by which seismic events are geometrically re-located in either space or time to the location the event occurred in the subsurface rather than the location that it was recorded at the surface, thereby creating a more accurate image of the subsurface. This process is necessary to overcome the limitations of geophysical methods imposed by areas of complex geology, such as: faults, salt bodies, folding, etc.

Wavefield Inseis

Wavefield Inseis was a Norwegian company trading between 2007 and 2009 that provided global marine geophysical services.

The association is intended for persons that are studying or otherwise professionally involved in geophysics, petroleum exploration, geology, reservoir engineering, mining, and civil engineering. EAGE operates two divisions: the Oil & Gas Geoscience Division and the Near Surface Geoscience Division. The head office of EAGE is located in the Netherlands, with regional offices in Moscow, Dubai, Kuala Lumpur and Bogota.

Seismic data acquisition

Seismic data acquisition is the first of the three distinct stages of seismic exploration, the other two being seismic data processing and seismic interpretation. Seismic acquisition requires the use of a seismic source at specified locations for a seismic survey, and the energy that travels within the subsurface as seismic waves generated by the source gets recorded at specified locations on the surface by what is known as receivers.
