Trinidad and Tobago Concludes Onshore and Nearshore Bid Round

On Jan. 9, Trinidad and Tobago’s Ministry of Energy and Energy Industries concluded the 2022 Onshore and Nearshore Competitive Bid Round. This bid round featured a total of 11 blocks covering more than 115,000 hectares. Blocks offered included Aripero, Buenos Ayres, Charuma, Cipero, Cory D, Cory F, Guayaguayare, South West Peninsula Onshore, St. Mary’s and Tulsa, located in the central to southern onshore Trinidad; and the South West Peninsula Offshore, located off the southern coast of Trinidad. Xavier Moonan, president-elect of AAPG’s Latin America and Caribbean Region and exploration manager of Touchstone Exploration Inc., follows the bid rounds closely.

Modular Oil Refineries Solve Efficiency, Environmental Problems

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.

Clean Energy Opportunity Adds to Super Basins Appeal

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.

Opportunities through Crisis

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.

Energy Investment in 2023 Tracks with Transition

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.

InSight Concludes with Key Findings in Martian Seismology

The successful Mars InSight mission employed a NASA/European Space Agency robotic lander designed to study the interior of Mars. The mission recently ended with last contact as its dust-choked solar panels failed to deliver enough electricity to keep InSight going. InSight had two science goals: Seek to determine the interior structure and composition of Mars and to reveal how a rocky planet forms, and to study the rate of Martian tectonic activity and meteorite impacts.

The Linchpin of the 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.

Orphaned Wells Present Continuing Problem, Opportunity for Geoscientists

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.

Latin America’s Path to Sustainability and Security through the Energy Transitions

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.

Seismic Impedance Inversion with Updated Low-Frequency Models

Seismic impedance is widely used in our industry because it allows an integrated approach to geological interpretation. The transformation of seismic amplitudes to impedance data can be essentially seen as the change from an interface property to a layer property. This stratal interval property (impedance) simplifies the lithologic and stratigraphic identification and can be directly converted into lithologic or reservoir properties such as porosity, fluid fill and net pay. It also allows for direct interpretation of three-dimensional geobodies.

Impact of Reprocessing Seismic Data

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?

Natural Increase of Oil Column Buoyancy and the Instability of Caprock Seals

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.

US Energy Forecast: Even Cloudier Than Usual

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.

Introducing the New EXPLORER, New Digital Newsletters

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.
