Define Reservoir Extent

The primary goal of deepwater reservoir studies is to answer essential questions about the structures and formations in the area of interest. The finest studies integrate the measurements and interpretation processes that will deliver the maximum number of correct answers possible.

Seismic acquisition

In deepwater exploration, there are few if any opportunities to rerun an operation. Acquiring data using complementary technologies and techniques builds confidence in the results. Combining seismic reflection data with resistivity contrasts and gravity add a new dimension to reservoir characterization.

• Marine Acquisition 
  WesternGeco, a business segment of Schlumberger, provides high-quality conventional marine seismic services, including 2D and 3D surveys of deepwater prospects. The Q-Marine point-receiver marine seismic system delivers exceptional data quality, unsurpassed repeatability, and the highest levels of operational safety, all of which are essential to deepwater reservoir characterization. 

Seismic processing and modeling

Conditioning data for inversion and other processing is the first step needed for obtaining quality modeling of geophysical properties and reservoir characteristics. With advances in computer power, it is now possible to integrate data from multiple sources for a more complete and efficient analysis of deepwater structures.

• Seismic Reservoir Characterization 
  Working with WesternGeco data processing groups, the Reservoir Seismic Services (SRC) brings together the people, technology, and workflows to integrate seismic data with borehole data and then processes the combined data for inversion. With worldwide expertise in seismic processing, interpretation, modeling software, and leading-edge ISIS suite of reservoir characterization technology, the SRC team takes seismic technology further into your reservoir for better seismic inversion and reservoir characterization. 
• Geology and Geological Modeling
  The Petrel E&P software platform provides seismic-to-simulation software capabilities for an accurate static reservoir description that integrates various acquisition data and evolves throughout the life of the reservoir.

Well testing

• Extended Well Tests
  Extended well tests are a valuable way to estimate reservoir volume and producibility, both of which are key elements to understanding the extent of the reservoir and its compartmentalization. In deepwater environments, these tests can be helpful in planning production facilities and in the overall economics.
