The Gippsland Basin in South-Eastern Australia has been producing hydrocarbons since the early 1960’s when several giant oil and gas fields were discovered. It can therefore be considered to be a mature area, where production rates have been declining for the last twenty years ...
Barreirinhas basin is located in the north-east of Brazil and is part of the Brazilian equatorial margin, a new exploration frontier with complex geology. This basin is characterized by a rugose water bottom, a fast carbonate platform, shallow gas pockets and a complex channel ...
Paper written in association with SNH for the March 2018 additions of First Break. Paper focusses on understanding why well success was low for the offshore Douala basin and how the interpretation of the results of the GeoSpec Regrid will enable a better understanding ...
This case study of an advanced quantitative interpretation workflow is tailored for a seismic multiclient program in the Wolfberry Play of the Midland Basin. Seismic imaging begins by providing a structural interpretation basis, then quantitative interpretation provides 3D elastic and geomechanical attributes through prestack ...
The Gippsland Basin in South-Eastern Australia is located approximately 200 km east of the city of Melbourne, and remains one of Australia's most prolific oil and gaThe major fields were discovered in the early 1960’s, using images from a coarse 20-km (12 mile) grid ...
Here we use a multi-client magnetic airborne survey to interpret and estimate the magnetic basement relief of the Jequitinhonha Basin. Satellite Gravity, seismic lines and well logs are integrated in the interpretation. Exudation points are also analyzed constructing a relationship between structural features and ...
In this work we propose to revisit some of the main steps of a seismic reservoir characterization workflow, using a MCNV Campos Basin broadband seismic dataset. The objective is to illustrate the differences with conventional seismic data, identify potential pitfalls and suggest best practices ...
Despite continuous improvements in seismic acquisition and processing technology, imaging under the salt remains very challenging, specifically because of the difficulty to update the complex salt geometries and the velocity under them. Synthetic studies show that when certain conditions are met, full waveform inversion ...
Demonstrate the value of least-squares migration on various complex geology around the world. It includes real data examples published by various SI teams such as least-squares Kirchhoff for tow-streamer/OBS 4D, LS-RTM for subsalt imaging, least-square Q-PSDM on Northsea & Austrialia.
