'Conventional geothermal reservoirs are characterized by a heat source, hydrothermal convection, and sufficient natural permeability to allow for fluid migration. Recognizing the geologically restricted occurrence of natural sites, additional opportunities have been sought. Enhanced geothermal systems are reservoirs in hot rock that lack the natural permeability required for fluid movement. In 2014, the U.S. Department of Energy initiated a program to test and develop new technologies for characterizing, creating and sustaining EGS reservoirs under natural field conditions. A site approximately 350 kilometers south of Salt Lake City Utah was selected for the Frontier Observatory for Research in Geothermal Energy, or “FORGE” laboratory. '

'Sourced in part by the Eagle Ford Group, the Austin Chalk has been a hot spot for operators on and off for a century. The rise of horizontal drilling and hydraulic fracturing brought a renewed interest in the formation, which has produced new discoveries in Texas and Louisiana. Yet in parts of the Austin Chalk, extracting oil and gas can be extremely tricky. Several years ago, the Carbonate Reservoir Characterization Research Laboratory at the University of Texas began a project to analyze approximately 40 cores from the Austin Chalk – the first group to do so.

Exploration of the Brookian-age Nanushuk and Torok formations on the North Slope of Alaska is a hot topic these days. The Nanushuk and Torok formations are Cretaceous progradational clastic deposits in the Colville basin of Alaska. These formations offer new opportunities to the oil and gas community because of their shallow depth, vast spatial extent, publicly available data, scope of development and other appealing features.

Josh Rosenfeld highlighted some perspectives on the Paleogene drawdown hypothesis in the Gulf of Mexico in the April 2020 issue of the EXPLORER, a result of suspected isolation from the world ocean during the Cuban arc-Bahamas collision with implications for Wilcox reservoir deposition. In contrast, John Snedden and authors’ portrayed the Wilcox as a period of normal marine deposition, requiring no such drawdown, in the May 2020 issue. Still another concept was presented by Roger Higgs at the South African 2009 AAPG International Conference and Exhibition, that marine isolation occurred but that fluvial input exceeded evaporation such that the Gulf became brackish, hence the poor development of Wilcox fauna.

Coherence and curvature are iconic attributes now commonly available on most interpretation workstations that help characterize small- and large-scale faults, large fractures, pinch-outs, buried channels, reef edges and unconformities. The quality of both these attributes, among other factors, relies on accurate estimates of volumetric dip. Coherence, amplitude gradients and GLCM texture attributes should be computed along structural dip, while curvature is computed from volumetric estimates of structural dip. Due to differences in both resolution and sensitivity to coherent noise, different frequency components might exhibit different dip. Such awareness has led to the development of multispectral coherence that makes use of summation of covariance matrices of individual spectral components, rather than just the covariance matrix computed from broadband seismic data.

Some 257 people gathered at the beautiful new Hilton Hotel in Port Moresby, Papua New Guinea in the last week of February 2020 to attend the first AAPG/EAGE Papua New Guinea Petroleum Geoscience Conference and Exhibition. The theme for the conference was, “PNG’s Oil and Gas Industry Maturing Through Exploration Development and Production.”

The interactive visualization of seismic attributes makes an effective use of color. Any color can be represented in RGB color space, which forms the working model for computer and television monitors. Normally, humans do not think of any color as a mixture of these three colors, but often refer to colors being more- or less-saturated, having different tones, or even one color being brighter than the other. Thus, besides the 3-D RGB color space, other more intuitive 3-D color models such as HSV and HSL have also been developed, with the application of the latter model for co-visualizing two or three different seismic attributes.

Shale resource plays are associated with low permeability, so hydraulic fracturing is required for their stimulation and production. In order to enhance the flow of fluids with hydraulic fracturing, it is vital to understand the stress field distribution. The efficiency and effectiveness of a hydraulic fracture stimulation are predicated on adequate horizontal well placement in the subsurface. For that purpose, the horizontal wells are usually drilled in the direction of minimal horizontal stress so that hydraulic fracturing takes place in the direction of maximal stress that ensures better reservoir contact and production, which also depends on how a complex fracture network is created by induced fractures.

The bandwidth of a signal is a measure of the breadth of its spectrum, often expressed as the distance measured in Hertz between the half-power points of a smooth spectrum. Bandwidth is the best measure of resolution. Although first introduced to the seismic community in the 1970s, only a limited number of published papers show the value of this attribute. In this column, we show the value of bandwidth when applied to data from the Utica area of Eastern Ohio, United States and from the Gulf of Mexico.

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.
