    Total awards CGGVeritas 4D inversion project

    Projects and Operations // June 4, 2009

    CGGVeritas has been awarded a major seismic reservoir characterization project by Total E&P Angola and their partners. The award is for the inversion of 4D seismic data covering the Dalia, Rosa, Girassol and Jasmine fields offshore Angola.  

    Hampson-Russell Software & Services, a CGGVeritas company, will undertake the inversion work, with a substantial amount drawing on the local expertise of our CGGVeritas Luanda processing and imaging centre.

    The project will use the Hampson-Russell proprietary global 4D elastic inversion product, StratiSI 4D.

    Philippe Doyen, Vice President, R&D, Hampson-Russell Services, said: “Having proved this technology in the North Sea, this is an important opportunity to apply it in West Africa. With the increasing number of 4D vintages available over producing fields, global 4D inversion is better constrained and yields results that are more readily interpretable in terms of production effects. In particular, it can provide quantitative estimates of reservoir properties, such as fluid saturation, with more certainty and capture the movement of fluids and changes in pressure with greater accuracy.”
