Petroleum reserves
The three featured papers illustrate how emerging computational methods—ranging from gradient-based optimization to data-driven proxies—are reshaping reservoir characterization, uncertainty assessment, and real-time decision support across diverse subsurface applications.
Latest 5-year assessment puts undiscovered technically recoverable gas resources on the US Outer Continental Shelf at 218 Tcf.
Westwood links 2026 exploration outcomes to policies, with operators offshore Norway finding seven times more resources than those offshore the UK.

Projections of future production in the Permian Basin may came up short because new wells drilled near older ones are likely to yield less. -
Despite a decline in oil and gas production and a decrease in revenue from 2015, an Ernst & Young’s study had a cautiously optimistic outlook as the industry adjusts to what it called “the new normal” of a lower, but stable, oil price.
-
Governments, companies, service providers, and many other stakeholders in the industry have realized the oil-price outlook may remain low for longer than expected and the need to plan accordingly.
-
This paper presents approaches for proper risking of uncertain recoverable volumes for an unconventional resource, taking into account the chance of false positives from appraisal-well information.
-
Compared to oil in the ground, the sun looks like a limitless energy source. Making comparisons of the two by calculating the equivalent of barrels of reserves for a solar project seems like an odd notion, but experts say it can and should be done.

In this work, the authors perform automatic decline analysis on Marcellus Shale gas wells and predict ultimate recovery for each well.

The authors present a geology-driven deep-learning estimated-ultimate-recovery (EUR)-prediction model for multistage hydraulically fractured horizontal wells in tight gas and oil reservoirs.
-
In drawdown management, operators can exert control over the downhole flow pressure, reservoir pressure, and choke size to avoid estimated ultimate recovery (EUR) losses.
-
The need for cost and capital efficiency calls for careful integration of technical and commercial elements.
