ION Geophysical was a technology-focused company that provided advanced acquisition equipment, software, planning, and seismic processing services, as well as seismic data libraries to the global oil and gas industry. Here are the key details: Company Overview: Name: ION Geophysical Corporation; Industry: Geophysical solutions for oil and gas
MESA is a seismic survey design software currently owned by ION Geophysical. [1] The software provides set of tools for optimizing onshore, offshore and transition zone survey design and planning. The software comes with three licenses namely, MESA field, MESA Professional and MESA Expert. [2]
Simultaneous Inversion (SI) is a pre-stack method that uses multiple offset or angle seismic sub-stacks and their associated wavelets as input; it generates P-impedance, S-impedance and density as outputs (although the density output resolution is rarely as high as the impedances). This helps improve discrimination between lithology, porosity ...
Geophysical survey is the systematic collection of geophysical data for spatial studies. Detection and analysis of the geophysical signals forms the core of Geophysical signal processing. The magnetic and gravitational fields emanating from the Earth's interior hold essential information concerning seismic activities and the internal structure.
A velocity filter, on the other hand, is a two-dimensional filter which produces a two-dimensional output record. A two-dimensional record can be generated by a procedure which involves repeatedly applying multichannel optimum filters to a small number of overlapping subarrays of the input data,. [8] [9] Fig. 1.
Multidimensional seismic data processing forms a major component of seismic profiling, a technique used in geophysical exploration.The technique itself has various applications, including mapping ocean floors, determining the structure of sediments, mapping subsurface currents and hydrocarbon exploration.
GLOBK accepts as input computed derivations from "GPS, VLBI, and SLR experiments" and, by means of a Kalman filter algorithm, gives output consisting of statistical estimates from various combinations of such derivations. [21] [22] [23] GAMIT/GLOBK requires a basic Unix- or Linux-based operating system, as well as several software prerequisites ...
The resulting output of the processing program is used as the input for subsequent interpretation. Processing may include the use of remote reference data or local data only. Processed MT data is modelled using various techniques to create a subsurface resistivity map, with lower frequencies generally corresponding to greater depth below ground.
