Reservoir Management Worldwide

Exploring Uncertainty in Subsurface Modelling and Forecasting

Ensemble-based modelling has been delivering value to the E&P industry for over ten years, causing a fundamental re-think of what exactly is needed to more accurately forecast the future behaviour of a reservoir’s performance and enable better decisions to be made on developing and managing the production of hydrocarbon assets.

Geology Australasia

Nature Shows Off

Most Surtseyan style eruptions involve a relatively small amount of water encountering magma. But the explosion in January this year at the Hunga Tonga-Hunga Haʻapai volcanic island erupted in a particularly spectacular fashion and the cause is still not yet fully understood.

Exploration Europe

Responsible Upstream Investment in the UKCS

In the UK’s ambitious net zero regulatory context, exploration can make a positive contribution to energy security, emissions reduction, local employment and revenue and tax generation to facilitate and subsidise future renewables growth.

Hot Spot Africa

The High Impact Hydrocarbon Potential of the Orange Basin

While the Mississippi, Congo, Nile, and many other major deltas around the world have been, and are being, successfully explored and developed, the vast Orange Basin offshore South Africa and Namibia has only recently started to reveal its enormous potential.

Exploration Africa

North Africa Round-Up

The North Africa region offers huge energy opportunities, but the bottom line is that its social challenges need to be solved.
