Explorer Article By Emily Llinás

Colombia’s indigenous U’wa community is rooted in tradition, and community members follow ancient ancestral customs, including living without electricity. Life changed for U ́was living near El Chuscal, Guandalay, in Northeast Colombia in November 2021, when a project developed by the University of Pamplona geoscience students brought electricity to their community for the first time.

Don’t Panic Just Yet Over Exploration Downturn

Worldwide oil and gas exploration results took a major hit from reduced investment and the ongoing COVID pandemic last year. Cautious industry spending and overall selectivity over prospects likely reduced discoveries to their lowest annual level in 75 years. Here’s the recommendation from one industry analyst for 2022’s global exploration and supply outlook: Stay chill for now.

Bringing ‘Friendly Energy’ to the U’Wa People of Colombia

The cloud forests in Western Colombia’s Andes Mountains are home to a diverse group of indigenous communities including the U´wa people. Community traditions prohibit members from using energy from non-renewable sources, so most lack access to electricity. Without computers and the internet, U’wa children’s education lags behind that of other Colombians. The story changed for one U´wa village when a group of geology students and AAPG Chapter members decided to reach out.

Making It All Work

Before unconventional resources became prevalent in the global petroleum supply, deepwater exploration and development was a significant focus for many larger companies. For deepwater activities to succeed, the petroleum industry was forced to merge its above-ground concerns with the below-ground geoscience and engineering disciplines.

2021 Marked by Oil Price Recovery, Industry Transformation

Producers finally got some relief in 2021. Oil and gas prices recovered from their pandemic lows and remained at high levels through most of the year, as increased production could not keep pace with a global demand recovery. It was a year when higher prices helped energy producers strengthen their balance sheets and improve their bottom lines.

A Source-to-Sink Project Boosts Colombia’s Subsurface Knowledge

While the COVID-19 pandemic ground the world to a halt in 2020, crisis led to creativity and opportunity in many parts of the world. For four geoscientists in Colombia, the pandemic became the perfect time to serve their country and their profession. In May 2020, two weeks after oil prices dropped below zero, Colombia’s Ministry of Science, Technology and Innovation launched a bidding contest allocating nearly $3 million to finance geoscience research projects for the hydrocarbon sector.

What Role Will Super-Giant Fields Play in the World’s Future Energy Mix?

Super-giant oil fields, by definition, are those fields containing at least 5 billion barrels of known recoverable crude oil or gas. It is believed they account for up the 40 percent of the world’s petroleum reserves, so their collective health – how much energy is being created at present, as well as how much can be – will play an oversized role in meeting the world’s future energy needs. “The interest in future oil supply waxes and wanes depending on price and supply, and these days climate takes up all the discussion about energy supply,” said Richard S. Bishop, past AAPG president and currently an international oil and gas consultant based in Houston.

Comparison of Machine Learning and Modeled Logs for Volumetric Assessment

As geoscientists, we are predisposed to associative thinking. Trained for pattern recognition by our education and experiences, we have learned to recognize familiar elements in a new dataset and integrate those pieces of information into a subsurface geological model. However, this learning system is usually biased and most of the time we are unaware of it. With the increasingly common use of machine learning in our workflows to bolster human interpretation, we must become increasingly aware of our biases, so that they they can be minimized as we train the algorithms. Herein is a case study and bias discussion from the Ceará Basin in Brazil, where deep convolutional neural networks are used to aid in the petrophysical analysis and volumetric assessment of a potential reservoir.

Pinedale Field: Case Study of a Giant Tight Gas Sandstone Reservoir

Edited by Mark W. Longman, Stephen R. Kneller, Thomas S. Meyer and Mark A. Chapin

This memoir contains 15 well-illustrated, peer-reviewed chapters that describe the history of field development, the deposition and diagenesis of the reservoir rocks, geophysical characteristics of the field, special core analysis techniques used to better quantify the reservoir, petrophysical characteristics and interpretations of the reservoir, the types and abundance of natural fractures, and fluid production characteristics in the field. Finally, static and dynamic models for the field are presented in an attempt to integrate all the pieces of this giant geologic puzzle.
