Survey Design Express #8
A novel approach to marine acquisition for full waveform inversion
This short video shows how TesserACT was used to design a low cost marine FWI survey making use of emerging "floating node" technology.
Survey Design Express #7
Marine streamer infill optimization
This video investigates the effectiveness of several techniques to reduce infill on a 3D seismic program. The example used is from a project where 2D and 3D programs must be acquired in a very short weather window. Streamer fanning proves to be a critical technology.
Survey Design Express #6
Simultaneous broadband acquisition of OBN and streamer data
In this video we look at some of the issues raised at the SEG 2019 workshop on marine data acquisition.
The requirements of FWI are driving many operators to acquire long offset OBN surveys to complement existing high resolution streamer surveys. In this video, we pose the question "can we acquire both surveys efficiently and simultaneously ?" ... and "could marine vibrators have a role to play in such acquisition ?".
Survey Design Express #5
TesserACT "operational analysis" tools show how to deliver a faster, cheaper and safer onshore survey .... without compromising geophysical data quality.
This video also highlights TesserACT automated tools for onshore hazard avoidance.
Survey Design Express #4
This video illustrates how TesserACT Operational analysis can be used to establish the right operational configuration for a seabed crew : number of receivers, number of vessels, number of simultaneous sources etc.
Survey Design Express #3
In this video, we examine some of the factors to be considered in designing an ocean bottom node survey for a deep water field development project in an area with extreme bathymetry. Topics considered include binning implications of receiver elevation changes, imaging wih multiples, variable density sampling and shear wave sampling.
Survey Design Express #2
This onshore project features steep slopes creating "no access areas". Other areas are accessible, but there is a cost penalty associated with the intermediate slopes.
This video shows how to adapt the survey design to improve safety and reduce cost with minimal degradation of the imaging performance.
