Workshop description

Three key discoveries in the last decade have triggered an exploration rush in distal margin sub-salt carbonates (following Tupi-Lula), in shear margins (following Jubilee) in the front of deltas (following La Rovuma). Only the first play seems promising and has brought significant volumes. Jubilee and la Rovuma are still exceptions and after a succession of disappointing wells, companies eyes turn again toward the mountain belts.
An estimated 15-20% of the conventional Yet-to-Find is still seen in the foothills. The last undrilled surface anticlines are being explored in Iraqi Kurdistan with somehow disappointing results.
The remaining reserves are thus in hidden structures or subtle traps that so far seismic cannot see. Concerning geology, most concepts have been established for 20 years. Academic research is now focused on surface processes driven by funding for CO2 and climate: thermochronology, source to sink, numerical modeling.
This workshop will therefore aim at reviewing foreseeable improvements either in seismic or alternatives methods, as well as to assess whether recent results in geological R&D have positive impacts on HC exploration.
