Currently, the global upstream landscape in 2025 undergoes a fundamental structural transformation. Specifically, senior leaders now pivot from high-impact frontier exploration toward the meticulous optimisation of mature basins. Consequently, this strategic reorientation responds to macroeconomic volatility and the urgent need for energy security. Companies now prioritise ‘advantaged barrels’. These hydrocarbons offer low cost, short cycle times, and reduced carbon intensity.

Just like reservoirs also seals can be good, or not so good. There is a whole spectrum of lithologies from excellent reservoirs to excellent seals. In fact, most seals leak. Some leak very fast, and then the seal is not effective; others leak not so fast or maybe very slowly, even at geological timescales, and then the seal is effective.
GeoExPro Issue 4: Drilling Deeper than the Primary Target – the Next Frontier?
Drilling a little deeper can sometimes result in a surprising find. Our cover story describes a series of discoveries from companies who are systematically exploring and producing hydrocarbons beneath existing accumulations.
