Drilling a little deeper can sometimes lead to surprising results. Our cover story explores a series of discoveries made by companies targeting hydrocarbons beneath existing accumulations.

We’re heading to Houston! As you may recognise from the front cover, the fourth issue of this year features an artist’s impression of a well being drilled in the Gulf of Mexico. There’s a good reason for this choice. In this region, and in many others worldwide, deeper drilling has revealed unexpected finds.

The cover story highlights several of these discoveries. Some were serendipitous, but recent developments show a clear shift. More companies are now systematically exploring and producing hydrocarbons below known fields. This approach is already proving successful in places like China and Saudi Arabia.

What else can you expect from this issue? We feature an interview with Sarah Stogner, a Texas-based lawyer who has recently made headlines. She is pushing companies to properly plug wells in the Permian Basin. Her confrontational style is unusual in the industry and could shake things up.

This issue also includes a strong selection of seismic foldouts. They take you from Trinidad to the Gulf of Mexico, on to Papua New Guinea, and back to the UK North Sea.

As always, our contributors share their subsurface expertise across a wide range of columns.
