Refineries are some of the largest carbon emitters in the world, and making them greener is no simple task. Yet, an effort to do so is taking place in West Texas in the heart of the Permian Basin. Here, two operators have received state permits to build small, modular refineries to process the light, sweet crude from shale formations with emissions that are roughly 95-percent lower than those from the average Gulf Coast refinery. Taking advantage of their location – where oil is produced and its finished products are needed – these operators have capitalized on the opportunity to build their own refineries from scratch, complete with carbon capture technology, and become some of the cleanest refineries in the country.

Energy super basins grabbed the attention of the oil and gas industry during the past five years, with good reason. Now a period of re-evaluation has kicked in. Producers are looking beyond total resource potential to apply other criteria, including economic, environmental and regulatory considerations. Those yardsticks could help identify which basins will dominate energy production in the decades ahead.

The Peruvian Congress’s ousting of President Pedro Castillo on Dec. 7 led to two weeks of protest throughout the country, with at least 50 reported dead in clashes with law enforcement. In Arequipa, Peru’s second largest city located 400 kilometers from the southern border, AAPG members Luis Alexander Alvarez and Alexandra Del Castillo took refuge in their homes. Alvarez, a mining and hydrocarbon geologist, said the social unrest directly affected him and his family.

Large institutions and asset managers are diversifying away from traditional oil and gas projects, sometimes driven by climate concerns, but their investments haven’t fallen far afield. Those organizations think in terms of billions of dollars when evaluating a potential investment sector. And so far, they haven’t hesitated to invest in energy. What has changed, and what keeps changing, is where they put those investment dollars. It’s an energy-investment transition that parallels today’s ongoing energy transition.

Last month the world’s political and industrial leaders gathered in Egypt for COP27. This annual event convened by the United Nations is an opportunity to engage in dialogue on the topic of climate change and to discuss a coordinated global response. If you’ve been paying attention for any length of time, you know that the topic of climate change and meetings like COP divide AAPG members. An individual member may or may not agree with the proposed policies or the concerns expressed at COP. But for many of our members worldwide, the topic of climate change and its impact on our industry and profession is existential – it has or will directly impact their careers and ability to practice their profession. That is why we must discuss this topic.

If you have attended any AAPG function or convention recently you have seen that we are striving hard to ensure that diversity and inclusion are upheld in everything we do. What does diversity and inclusion entail, and why are we striving hard to factor it into our planning? Does it skew our planning in favor of one group or another? Is it a quota system mandated by the government? Are we doing this just to be “fair”? Finally, why does an old silver-haired dinosaur such as myself champion the importance of diversity and inclusion within AAPG?

The first U.S. oil well was drilled 1859 in Titusville, Penn., and the first commercial gas well was even earlier in 1825 in Fredonia, N.Y. There are two centuries of oil and gas drilling in the United States, and many of the wells in the first 150 years did not have the best plug-and-abandonment methods in place. Some of these wells are in urban areas and can endanger the residents. The number of orphaned and abandoned wells varies greatly depending on their definition. There might be millions of old and improperly plugged oil and gas wells leaking methane or contaminating groundwater in the United States, and plugging them will cost billions.

Why deepwater? In addition to expanding our knowledge on sedimentary systems that cover 70 percent of our planet, deepwater systems host promising resources and energy potential for the future. Their characteristic high-rate productivity also means fewer wells, which is good news for lower carbon emissions. Deepwater systems also benefit from the highest quality offshore 3-D and 4-D seismic. Thus, we see more clearly with ever-improving technology. Deepwater concepts and paradigms are rapidly evolving. The 2022 book “Deepwater Sedimentary Systems” sets a firm and comprehensive foundation.

I have the honor of leading the executive secretariat of ARPEL, the Association of Oil, Gas and (as of lately) Renewable Energy Companies of Latin America and the Caribbean. ARPEL is a key factor in the development and transformation of the oil and gas sector of our region. We foster cooperation and coordination on strategic and operational aspects among our member companies, and with sister trade and professional associations (such as AAPG), governments, regulators, academia and other stakeholders. ARPEL held its 6th conference in Lima, Peru in November.

As countries seek to transition to cleaner-burning fuel to address environmental concerns, it can also be argued that the need to eliminate energy poverty remains just as crucial. The future energy mix must be wide-ranging and diverse to meet the needs both of the environment and the people living on the planet. New companies have begun to bring geothermal energy to areas that aren’t adjacent to volcanoes or that don’t have access to tectonic settings, which allow for an easy harvesting of the Earth’s heat. Some are embracing the niche operation of repurposing traditional geothermal wells and non-producing oil and gas wells. Others are promoting widespread geothermal energy through deep vertical and multilateral wells that can bring heat and electricity to the masses.

Advancements in processing and imaging techniques have continued over the last several decades, which have gradually improved the quality of the processed surface seismic data. When the quality of the existing seismic data is not adequate to perform an interpretation task reasonably, then the interpreter looks for other options. Is it feasible to acquire a new survey? In the absence of an improved survey, will reprocessing of seismic data be a good option?

Perhaps you did a double take pulling the April issue of EXPLORER from the mailbox. What is this? If you joined AAPG in the last 40 years, you’ve only known EXPLORER in its long-standing tabloid format. It worked well for many years as our advertisers – particularly seismic companies – loved the large format and the ability to display their data on a sweeping canvas. For readers, it was a little more awkward.

A new type of buoyancy model can be used to understand the source of residual oil zones, both thick and thin, to help determine the likelihood that economically viable recoverable oil resides in transition zones of imbibition reservoirs. Application of a buoyancy and breech model will fill a void in reservoir characterization. It will help distinguish between TZs and ROZs, the first of which allows application of primary and secondary (waterflooding) oil recovery methods and the second of which requires more difficult CO2-enhanced oil recovery projects.

It isn’t news to anyone that prediction is difficult, especially when it’s the future (as a great man once said). Uncertainty and unpredictability are just a part of the job of tracking and predicting the future supply and demand of energy. That being the case, when energy analysts say that the current level of uncertainty is particularly high, it might be easy to dismiss it as a “dog bites man” story. It isn’t.
