While the outcry against the petroleum industry drilling in residential areas is as high as ever, a small, privately-held petroleum and real estate company in Midland, Texas, is making headlines for pulling off what some might consider an impossible feat: creating communities where people are willingly moving onto active oil and gas fields and living harmoniously with t he industry.

The StatesFirst working group on induced seismicity just released its report,” Potential Injection-Induced Seismicity Associated with Oil & Gas Development: A Primer on Technical and Regulatory Considerations Informing Risk Management and Mitigation.” The report describes the causes of and ways to prevent induced earthquakes. It also looks at the interaction between regulators and the public, and the report includes case studies of how states have responded to instances of suspected induced seismicity in California, Oklahoma, Ohio, Illinois, and Colorado.

The discovery and untimely loss of the Jusepin Deep Field in Venezuela is a story of creativity, perseverance, technical excellence and emotion – which are qualities we as geoscientists like to feel we bring to our jobs every day.

The key elements for shale resource evaluation are the mineral content – such as clay, quartz and calcite – the total organic carbon (TOC) content, the brittleness and some mechanical properties of the shale rocks. Geomechanical studies are necessary both for understanding wellbore environment stability and also interpreting well log data, by estimating the mechanical properties of the subsurface.

Times may be tough for seismic companies, but not all companies are waiting for the current storm to pass. Spectrum ASA recently moved to gain a greater global footprint by purchasing Fugro’s 2-D seismic library – a move Spectrum CEO Rune Eng called a “game changer” for the multi-client seismic imaging company.

The discovery and imaging of a mammoth magma reservoir beneath the Yellowstone supervolcano is a capstone to decades of research. Scientists have long known of a smaller magma chamber, but the new chamber – 4.4 times larger – helps answer the questions about the volcanic system.

Traditionally ignored, the azimuthal dimension enables more information to be squeezed out of 3-D seismic.

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.
