Vol. 21

Issue 5

This magazine breathes Africa – from the cover story via the seismic foldouts to our feature stories and columns. And it is for a reason, because we will bring this issue to Africa Oil Week.

Before we discuss Namibia, Ian Cross makes a case for governments to introduce open door policies with regards to attracting majors to carry out exploration campaigns. Increased competition for just a handful of players is behind this, and it comes with a call for high-quality subsurface data when establishing a data room.

Our cover story discusses the Namibia deep-water hotspot, where the massive finds have not only yielded enthusiasm, but also some doubts when it comes to reservoir quality and gas content. We look at these things a bit more, whilst also illustrating Namibia’s deep-water play with yet another sketch from Marcos Asensio.

Peter Elliott’s story around Africa’s exploration hotspot in Ivory Coast is a great overview of how decades of exploration can be turned into a major success, which is nicely complemented by Viridien’s foldout on the matter.

What else can you expect from this issue? An interview with Aluka Osakwe, who grew up in Nigeria, but subsequently travelled the world and finally settled in the UK, from where she now runs her growing consultancy network. Aluka clearly represents the upcoming generation of oil and gas entrepreneurs, and she is proud of it.

And, as always, our contributors share their subsurface expertise in a wide variety of columns.

A mystery

The upper Permian Zech­stein of the UK Southern North Sea is experiencing a little revival these days. The main reason is that gas and some oil were discovered last year Read More

3 million versus 100 k

Once large-scale CO2 injection projects will hopefully ramp up, monitoring injection will be an essential part of the work­flow. And because the carbon storage business will never be a commercial Read More

A seismic facies library

Seismic facies classification can be a tedious process, especially in an exploration context where large areas need to be as­sessed. In order to speed up that process, using a library Read More

Joining the race

When looking at activities when it comes to the development of deep-sea mining technology and the licensing aspects of it, it is easy to be drawn to the news around Read More

Fairy circles

Companies ex­ploring for natu­ral hydrogen are rapidly popping up everywhere, but how do the geologists decide where to start prospecting? Many of them look at historical data from “dry” hydrocar­bon Read More

The birth of a new play

This is a story of how subsur­face data was used in the way it should be – to incremental­ly gain a better understand­ing of how a petroleum system works. And Read More

A leak – but what next?

The E&E News website, part of Politico, recently published the news that the US Envi­ronmental Protection Agen­cy (EPA) issued a violation notice to the operator of the Decatur CCS pro­ject Read More

Subsurface exploration by plane

Data, particularly information about subsurface geology, is key to successfully exploiting natural resources, be they mineral, hydrocarbon or renewables such as geothermal and natural hydrogen. Especially in Africa, where large Read More

A huff-and-puff reservoir

“I would not be in this business if we would not think we can produce competitively priced energy”, said Mike Eros from Sage Geosystems during his talk in the Geothermal Read More

Ivorian renaissance

The petroleum provinces of Cote d’Ivoire are amongst the hottest properties in the exploration sector at the moment. While oil and gas regulators and operators work hard to stimulate investment Read More

Never say no

“I was born disciplined”, says Aluka at the start of the interview. “With my parents both being academics, it was no surprise that I wanted to learn”, she continues, “but Read More

Gravel and geothermal energy
