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 ...

The scope for using EO satellites for routine monitoring of offshore operations is continually expanding in ways that make factors of cost and time more feasible than ever before. Near-real-time processing and delivery remain the most appropriate solution for emergency scenarios; however, proactive monitoring ...

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.

A new method is outlined that allows you to use isotropic seismic modeling and inversion technology in an anisotropic setting. The method is based on the mapping of the isotropic elastic parameters into effective elastic parameters, appropriate for the expected type of anisotropy. This ...
