Broadband Seismic Technology and Beyond
Part I: The Drive For Better Bandwidth And Resolution Once a new technology rolls over you, if you’re not part of the steamroller, you’re part of the road. One such…
Folds and Folding – Part I
Rock folds are found in various shapes and sizes on Earth, and people are often amazed to see how large blocks of hard rocks have been folded like ocean waves.…
Remote Sensing Underground
Satellite remote sensing uses specific frequency bands to reveal details about the surface of the earth. By borrowing this idea and applying it to broadband 3D seismic data, reservoir heterogeneities…
Gas Hydrates – Part III: Rock Physics Hydrate Experiments
“In science one tries to tell people, in such a way as to be understood by everyone, something that no one ever knew before. But in poetry, it’s the exact…
Into the Abyss!
Borehole seismic – the technological challenge of listening at extreme depth. William Wills of Avalon Sciences discusses some of the principle requirements driving borehole seismic technology innovation. The domain of…
Mapping sub-salt and sub-basalt structures from magnetic and gravity data
The acquisition of modern high-resolution airborne magnetic and gravity data has revolutionized the use of potential field methods in oil and gas exploration. Archimedes Consulting is one of the companies…
From Core to Pore
Advanced technology can now be taken into remote field environments to make lithology description much more detailed and accurate than was possible before From the early days of hydrocarbon exploration,…
Gas Hydrates Part IV: Where Are Gas Hydrates Found?
The need for energy is driving much of the current natural gas hydrate research. “While research on methane hydrates is still in the early stages, these research efforts… could potentially…
Unique and Fast Analysis in the Field
Field-portable x-ray fluorescence (FPXRF) is a technique that is gaining momentum and acceptance in addressing applications in various fields in geology and mining. Thousands of these instruments are currently used…
Reading Between the Lines
Point-receiver data, isometrically sampled in both crossline and inline directions, fully captures the three-dimensional seismic wavefield for the first time. Even the most cursory study of an outcrop such as…
