It wasn’t so long ago that geologists and geophysicists each labored in their own separate universe, so to speak, with little or no direct interaction. In the mid-to-late 1990s, 3-D seismic grew to prominence as a kind of end-all, be-all in the E&P realm, soon creating a synergy between these professions that is considered to be routine today.

A geoscience company some have billed as “Silicon Valley meets the oil patch” has undertaken a study over the Allegheny National Forest in Pennsylvania. Airborne geophysical datasets newly acquired by NEOS GeoSolutions were combined with existing seismic, well, and public domain datasets to better understand the potential of the Marcellus resource play in a roughly 2,500 square-mile area of investigation.

Colombian geophysicist Jaime Checa, the current president of AAPG Affiliated Society Asociación Colombiana de Geólogos y Geofísicos del Petróleo (ACGGP), is dedicating his presidency, and much of his free time, to combating misinformation related to seismic acquisition in Colombia.

It might be a well-worn saying, but it fits perfectly in today’s industry environment: When the exploration business sneezes, the seismic business gets the flu. Seismic acquisition companies have financial aches and pains this year because of a reduction in capital expenditures for oil and gas exploration work, especially by international oil companies.

The exploration expeditions in Alaska beginning in the late 1800s trump most other places in the world: The nuances of geology and geophysics required to find oil and gas in America’s last frontier tell the technical side of the journey, but mix in a history of Native Americans and Russians leading explorers to oil seeps, Hollywood investors, sled dog exploration teams, and rigs disassembled and transported by air for the first time – and science inevitably becomes a bit of lore.

Recent announcements have positioned the Springer Shale as a potentially prolific producer at 12,500 ft depth, with Continental Resource’s initial tests producing more than 2,000 barrels per day.The Springer, which is a Mississippian-Pennsylvanian boundary zone formation has been an important oil and gas producer in both southern Oklahoma and in the Anadarko Basin.

The Granite Wash of the Anadarko Basin of Oklahoma and Texas has been a remarkable challenge with prolific results for operators who have solved the mystery of a highly complex play. With up to 18 producing zones, extreme compartmentalization, and pressures that can be challenging, all phases of exploration, drilling, and production require special knowledge.

Saharan fields Hassi Messaoud (10 Gb reserves, discovered in 1956) and Hassi R’Mel (100 Tcf gas plus 2.4 Gb condensate reserves, discovered in 1957) are by far the largest oil field and the largest gas field in Africa

The purpose of this article is to describe a workflow for discriminating limestones and dolomites, and to map the lateral extent of dolomite reservoir rocks that have a thickness below the seismic resolution.

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.

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.

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.
