The debut of high-resolution aeromagnetic surveys in the early 1990s was received with great interest by the oil industry for exploration of both mature and frontier basins. In less than a decade, many of the active sedimentary basins in North America were covered by spec HRAM surveys. The interest in the application of these HRAM surveys slowly subsided as the basins became more mature and were covered by high-quality 3-D seismic surveys. However, after a nearly 30-year hiatus, there has been a renewal of interest.

In February 2023, the Society of Petroleum Engineers, together with the AAPG and the Society for Exploration Geophysicists, conducted a one-day symposium on the energy transition. The invitation-only event, hosted by the Canadian embassy in Washington, D.C., was designed to inform and engage policymakers and the policy community in the U.S. capital from the perspective of the engineers and geoscientists who currently work to supply 60 percent of the world’s energy.

The processing of land seismic data entails a series of steps through which the data passes, including sorting, static correction, deconvolution, residual static correction, velocity analysis, migration, stacking, filtering and scaling. Some tasks, such as velocity analysis, are interactive, while others are automated. The processing of seismic data from the same area often follows the same proven series of steps or sequence, barring any unforeseen issues that need to be addressed. Such a sequence of tasks designed to process data from their initiation to completion is referred to as a “workflow.”

Alaska’s North Slope is the best conventional onshore oil play in the world. That’s according to Bill Armstrong, CEO and president of Armstrong Oil and Gas, Inc. And, he will give no quarter on his belief about how robust the future is for the North Slope’s prospects. In short, Armstrong calls the area “incredible.”

In the early days of analogue recording, geophysicists used seismic data primarily to map structure. However, improvements in data quality by the late 1960s led to the identification of lateral changes in amplitude as well. When the drill bit revealed that some of the higher amplitude events correlated to gas-bearing zones, interpreters started taking them seriously. These streaks of high amplitudes seen on seismic sections were christened “bright spots.” The initial excitement was tempered by the realization that not all bright spots correspond to gas.

Being an AAPG Distinguished Lecturer, from the very first speaking tour in 1941, was always a prestigious achievement and a source of honor and pride for those selected as speakers. It was always recognized and praised as an important vehicle for the profession’s top geoscientists to share the latest in industry insights and advances. It always showcased geologists who truly were distinguished. What it wasn’t always, was easy.

Explorer Historical Highlights

The idea of an oil-finding instrument was not new. Water dowsers were common throughout the United States and among most people of European descent worldwide, and they were quickly adapted to looking for oil. Soon after the Drake well in 1859, people started working on inventions to detect oil by geophysical methods.

To achieve net-zero carbon emissions by 2050, the demand for renewable energy is increasing exponentially, with offshore wind farms as one potential area of investment. Offshore wind farm development requires effective mapping of near subsurface for turbine foundation design and construction, which faces many challenges related to seafloor topography mapping, shallow geohazard detection, structure interpretation and modeling, soil type analysis and geotechnical property estimation, among other considerations.

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.

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.

DL Abstract

Around 170 million years ago, the Gulf of Mexico basin flooded catastrophically, and the pre-existing landscape, which had been a very rugged, arid, semi-desert world, was drowned beneath an inland sea of salt water. The drowned landscape was then buried under kilometers of salt, perfectly preserving the older topography. Now, with high-quality 3D seismic data, the salt appears as a transparent layer, and the details of the drowned world can be seen in exquisite detail, providing a unique snapshot of the world on the eve of the flooding event. We can map out hills and valleys, and a system of river gullies and a large, meandering river system. These rivers in turn fed into a deep central lake, whose surface was about 750m below global sea level. This new knowledge also reveals how the Louann Salt was deposited. In contrast to published models, the salt was deposited in a deep water, hypersaline sea. We can estimate the rate of deposition, and it was very fast; we believe that the entire thickness of several kilometers of salt was laid down in a few tens of thousands of years, making it possibly the fastest sustained deposition seen so far in the geological record.

DL Abstract

Three-dimensional (3D) seismic-reflection surveys provide one of the most important data types for understanding subsurface depositional systems. Quantitative analysis is commonly restricted to geophysical interpretation of elastic properties of rocks in the subsurface. Wide availability of 3D seismic-reflection data and integration provide opportunities for quantitative analysis of subsurface stratigraphic sequences. Here, we integrate traditional seismic-stratigraphic interpretation with quantitative geomorphologic analysis and numerical modeling to explore new insights into submarine-channel evolution.

VG Abstract

In comparison with the known boundary conditions that promote salt deformation and flow in sedimentary basins, the processes involved with the mobilization of clay-rich detrital sediments are far less well established. This talk will use seismic examples in different tectonic settings to document the variety of shale geometries that can be formed under brittle and ductile deformations.
