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 ...

TopSeis is a radically new solution for seismic acquisition and imaging, developed through collaboration between an oil company and the service sector.

Seismic inversion transforms seismic reflection data into quantitative rock-property descriptions of a reservoir. Seismic data bandwidth is limited by signal-to-noise ratio, absorption, source wavelet, and shot and receiver ghosts. A typical deterministic seismic inversion workflow fills the low frequencies by extrapolating or interpolating existing ...

Least-squares migration (LSM) can potentially provide better amplitude fidelity, higher image resolution, and fewer migration artifacts than standard migration. Conventional LSM is often solved iteratively through linearized inversion, and therefore is often referred to as iterative LSM. In recent years, various single-iteration LSM approaches ...

DALLAS–The great land grab in the Midland Basin has resulted in an exponential increase in acreage prices, with buyers paying up to $60,000 an acre in some cases. In this competitive environment, oil and gas companies–particularly smaller independents–are starting to look for prospective areas ...
