Explorer Geophysical Corner

In last month’s Geophysical Corner we considered how to improve the seismic resolution of deepwater, near-seafloor geology using P-P data acquired with seafloor-positioned multicomponent sensors. This month we move to part two: We show how P-SV (converted-shear) data acquired with these same sensors provide even greater resolution of deepwater, near-seafloor strata.

You ain’t seen nuthin ‘til you’ve seen the Tuscaloosa! Sound familiar? If so, it’s because this was probably the most popular talk making the rounds of the professional meeting circuit in the late 1970s.

Unconventional hydrocarbons are so like, well, in these days. Indeed, coalbed methane, shale gas, oil sands and such have quickly become the darlings of many operators and financial analysts alike. But there are other things to be excited about as well.

Like Estragon and Vladimir, who are waiting for the inevitable in Waiting for Godot, geologists, too, are waiting for an earthquake to come to Los Angeles and its surrounding communities. And like the two protagonists in Beckett’s masterpiece, they also don’t know when it will come, where it will appear or the extent of its impact.

Even the bravest of souls are known to fear Mother Nature’s wrath, which can be mighty scary, unpredictable and often fatal. In the case of potentially devastating events like slow-moving hurricanes, there’s time to prepare to ride it out and take your chances -- or else “get out of Dodge.”

Oil in Belize. It could be an epic poem written by Byron, or a knowing verse by Rudyard Kipling. It’s also a ripping adventure, with a small band of True Believers finding victory on a remote frontier.

Multicomponent seismic data have unique value for studying near-seafloor geology in deepwater environments. When properly processed, P-P (compressional) and P-SV (converted-shear) images made from 4-C seismic data acquired in deep water with seafloor sensors show near-seafloor geology with amazing detail. This article is the first of two that describe how improved imaging of near-seafloor, deepwater strata can be achieved with conventional multicomponent seismic data.

Many people today view land surfaces from commercial airplanes or on satellite images and are amazed by the geomorphic forms of river channels, deltas, barrier islands, dune fields and other features. These views show us modern stratal-time surfaces of exposed landforms. Three-D seismic technology has now made it possible to image similar, but much older, geomorphic features and stratal surfaces preserved in the rock record.

Environmental concerns are a major factor in all U.S. exploration, but it is especially true in the West. That includes Wyoming’s Pinedale Field, a tight gas sand giant in the northwest part of the Greater Green River Basin.

Short Course
Bogotá , Colombia
Thursday, 10 November Friday, 11 November 2022, 8:00 a.m.–4:00 p.m.

This 2-day, in-person course describes the range and variability in deepwater sedimentary systems and equips participants to build predictive models of subsurface geology for more successful exploration and development. A primary goal of this course is to enable subsurface teams to more effectively characterize and rank deepwater/offshore projects on a regional and global scale.

The sedimentary basins of the Middle East have been proved to contain vast hydrocarbon reserves, sourced by some of the most prolific petroleum systems in the world. This is the product of a range of factors, not least the long-lived, relative stability of the Arabian Plate and the presence of multiple, prolific organic source rocks. This workshop will address these and other subjects and to discuss the main challenges present in our current understanding of petroleum systems in the Middle East.

Assistant Professor of Hydrogeology

The Boone Pickens School of Geology at Oklahoma State University invites applications for a tenure- track, assistant professor position in physical hydrogeology. The anticipated start date is August 1, 2023. The successful applicant must have a Ph.D. degree in geosciences or a related field at the time of appointment. Postdoctoral experience is preferred. The School encourages applications from candidates from underrepresented groups in the geosciences.

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.
