Deconvolution is a process universally applied to seismic data, but is one that is mysterious to many geoscientists.

The Jonah Field in the northern Greater Green River Basin, one of the largest gas discoveries in the last decade and a poster child for basin centered gas. The Standard Draw-Echo Springs Field in the Washakie Basin, which was found in the 1970s and was one of the original fields determined to be a large, basin centered gas accumulation.

Thanks to stubbornly-high commodity prices, record profits are being rung up at a host of oil and gas firms. For the most part they're using the accruing volumes of cash to pay down debt and spruce up their financial standing in general.

Any 3-D seismic survey can have an acquisition footprint. Our problem is to determine whether we have one -- and if so, whether we can recognize it, how severe it is and, most importantly, what we can do about it.

Workshop
Tulsa, Oklahoma
Tuesday, 18 February Wednesday, 19 February 2025, 7:00 a.m.–5:00 p.m.

Join us for AAPG Orphan, Abandoned, Idle and Marginal Wells Conference 2025. This workshop will focus on orphan, abandoned, idle, and marginal wells and the business opportunities and technology associated with plugging and repurposing wells, reducing methane emissions, protecting water supplies, and extending the lives of marginal wells.

Field Seminar
Houston, Texas
Saturday, 1 February 2025, 8:30 a.m.–1:00 p.m.

Everyone in Houston lives within a few miles of a bayou. Some people think of them as permanent, but the bayous are constantly changing, especially during high water events like Hurricane Harvey. This trip is a 2.5 mile walk down a section of Buffalo Bayou where we will look at the archives of past storms and discuss what to do for future storms.

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.
