Vol. 22

Issue 1

Conversations, that is the first thing we think about when looking at this issue of the magazine. Around 50 people contributed to it, and many of those we spoke to personally over the phone or on Teams. Sometimes just for a little insight on a particular technical issue, and sometimes to hear about an entire career.

Our regional focus this time is in Southeast Asia. This is reflected both in the cover story about the Andaman Sea, and our portrait interview with Aqilah Amir Jamalullail from PETRONAS. Aqilah tells about her humble background, trying to make ends meet as part of a large family, and the way she was and still is determined to make a difference.

In recent years, the Andaman Sea has produced some intriguing exploration results. Andy Racey and Andy Taylor present an update on the wider area and its further potential, while Rob Chambers reflects on the development scenarios of the gas finds.

Finder Energy, in collaboration with Searcher, takes the reader to Timor Leste to discuss the development potential of a series of discoveries and how reprocessed seismic resulted in an uplift of imaging quality. At the same time, PSS GEO, in their first-ever foldout article, discuss the interesting outcomes of a geothermal exploration study and how this can be used to accelerate finding new targets.

Our returning sections host a range of new insights from oil in igneous rocks in Oman, an overlooked mechanism to explain hydrocarbon leakage from reservoirs, and how tracer technology is being pushed to the limit for geothermal energy projects.

And finally, a warm welcome to Juan Cottier who has written his first column for the magazine in what promises to be a great and original series of geoscience insights and more!

Is it a true conjugate fracture set?

Conjugate faults or frac­tures are a set of shear frac­tures that formed simul­taneously under the same stress conditions. According to Ander­sonian Fault Theory, this could involve a series of left-lateral Read More

Fault-valve behaviour of petroleum traps

When evaluating fault-bound traps, it is common practice to map around-the-fault pathways through diligent seismic interpretation, juxtaposition diagrams, and 3D structural framework construc­tion. It is also common practice to ad­dress Read More

The geology of Bronze Age epics

A New Year brings new challeng­es, and for me, that means writing for GEO EXPRO. I am writing after the Xmas break which is tradition­ally eating, drinking and watching old Read More

Indonesia bid round push continues

In Asia Pacific, Malaysia has been arguably the most successful coun­try in promoting its exploration and development opportunities over the past few years, with the vast majority of its acreage Read More

A legacy of hyperpycnal flows

The cretaceous U and T sandstones, key petroleum reservoirs in the Oriente Ba­sin of Ecuador, have been the focus of a groundbreaking reinterpre­tation. Recent studies of subaqueous systems and high-resolution Read More

From scratch

“No data, no problems,” laughs Tan­guy Lomme from Epslog when he reminisces on his years at Shell when he worked as a reservoir engineer. As soon as he joined founder Read More

Oil in porous intrusive rocks

Basement plays are found in quite a few areas globally and have been well studied and reported on. Norway, Yem­en, Vietnam and China are amongst those places where oil is Read More

Action in Andaman

Before taking a dive into the past, recent and future ex­ploration activity in the An­daman Sea, it is good to take note of an important above-ground advantage of the area. Read More
