Many hydrocarbon producing basins in the world are dominated by vertical hydrocarbon migration. This hydrocarbon migration is often directly detected in the seismic record as zones of vertically aligned, chaotic, low energy data. Depending on their morphology we term these features gas chimneys, mud volcanoes, or gas clouds. In 1998, dGB and Statoil invented the Chimney Cube, a volume that has proved to be very useful in the study of petroleum systems. Since the first application dGB created hundreds of chimney cubes and published more than 50 technical papers on fluid migration, fault seal analysis and ranking prospects with seal and charge risks.
Chimney Atlas
The Chimney Atlas gives an overview of fluid migration path studies, condutcted by dGB and others. The altas contains geographically referenced links to videos, papers, books, posters and annotated PowerPoint presentations that can serve as analogs for other studies. We invite everyone with peer-reviewed papers to share this information via this free platform. Please contact
Services
We use our chimney expertise to help clients rank their prospects and to perform fault seal analysis. Prospect ranking is based on classifying chimneys and calibration against our database of analogs. We classify chimneys on appearance and on spatial relationships between chimneys, faults and traps. In fault seal analysis we compare chimney cubes with fault (similarity) cubes. The output is a qualitative measure of fault leakage.
