Reservoir studies must answer essential questions about deepwater structures and formations. The best studies integrate the measurements and interpretation processes that will deliver the most answers possible—from all scales and angles.
Data Acquisition
In deepwater exploration there are few chances to "do things over." Acquiring data using complementary technologies and techniques builds confidence in the results. Combining data based on the measurement of seismic reflections with that based on resistivity contrasts and gravity adds a new dimension to reservoir characterization.
- Marine Acquisition
WesternGeco high-quality conventional marine seismic services include 2D and 3D surveys for deepwater prospects. Q-Marine technology delivers exceptional data quality, unsurpassed repeatability, and the highest levels of operational safety, all essential in deepwater reservoir characterization.

Gravimetry
Structures conducive to hydrocarbon accumulations can be spotted by combining cost-effective gravity surveys and ocean-bottom profiling, which uses density measurements to highlight salt domes and depositional features such as ancient riverbeds.
Data Processing and Modeling
Conditioning data for inversion and other processing is the first step toward 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.
- Reservoir Seismic Services
Working with WesternGeco data processing groups, Reservoir Seismic Services integrates seismic data with borehole data and processes the combined data for inversion. The generic four-stage workflow involves wavelet extraction, static or dynamic inversion, rock physics, and reservoir modeling using ISIS simultaneous inversion software. The result is greater accuracy in deepwater reservoir characterization.
- Geology and Geological Modeling
Petrel seismic to simulation software capabilities provide an accurate static reservoir description that integrates various acquisition data and evolves throughout the life of the reservoir.
-
Reservoir Delineation
Our Reservoir Delineation package integrates services to accurately determine the lateral extent and thickness of a reservoir. Seismic services help define the extent of a basin, and combining seismic surveys with LWD and MWD data and wireline logs provides the input to build a realistic model using Petrel software.
Extended Well Tests
Extended well tests are a valuable way to estimate reservoir volume and producibility; both are key elements to understanding the extent of the reservoir and its compartmentalization. In deep water this can help in planning production facilities and in overall economics.
