In the onshore world, one of the big advances for addressing increased sampling requirements has been to go to 24-hour shooting with continuous recording of simultaneously sweeping vibrators. This has been enabled by innovations in both acquisition and processing.
Schlumberger Exits Seismic Acquisition Business
Schlumberger has decided to quit the seismic acquisition business due to poor financial returns.
This Vision of Onshore Seismic May Look Strange at First
Faced with big potential discoveries under terrain that makes good seismic imaging impossible, Total is rethinking how to gather the data it needs, with an idea that could change the face of seismic exploration.
Oil and Gas Seismic Work Leads to Data-Sharing Deal in Norway
"Today we know more about the surface of the Moon than our own seabed."—Sturla Henriksen, CEO of Norwegian Shipowners' Association
India Asks Big Oil Companies "Where Do You Want to Drill?"
India will test whether it can reach its ambitious goal of reducing oil and gas imports by 10% by 2022 with an upcoming auction of oil properties.
Better, Less Tedious, Fault Interpretation
The tedium of identifying small faults in often murky seismic images pushed Dustin Dewett, an associate geophysicist for BHP Billiton, to develop a better way to use the tools at hand.
Near-Surface Velocity Model To Enhance PSDM Seismic Imaging of Dukhan Field
Integration of microgravity, resistivity, and seismic data improves the fidelity of seismic images and the depth match.
The world’s first reflection seismic field tests were conducted near Oklahoma City in 1921, and, ever since then, the industry has endeavored to improve that seismic imaging process.
Broadband Seismic Acquisition: Implications for Interpretation and Reservoir Models
Acquiring new 3D broadband seismic data of a gas field containing legacy 3D conventional towed-streamer seismic data.
Downturn Represents Stress Test for Unconventional Hydraulic Fracture Modeling
Developers of the latest generation of unconventional hydraulic fracturing models are hoping that current weak oil and gas prices will generate newfound interest in their software technology.
Offshore Seismic Feeling Pressures to Change
Seismic innovators are working on new sound sources designed to produce better subsurface images while addressing concerns raised by scientists and regulators about the environmental impact of the related noise on sea life.
Competing Companies Building Robots to Place Receivers
Autonomous Robotics’ first offering is built around a rounded yellow device that looks like a little flying saucer.
Air Gun Inventor Creates A Lower Pressure Option
More than 50 years after inventing the air gun, Stephen Chelminski is working on a new version of the industry standard designed to be more in tune with the current needs of the industry and its regulators.
Seismic Data: Looking for Oil From More Angles
New seismic data gathering techniques promise better images for less by gathering more data quicker, seeing past obstructions, and seeking out scarce frequencies.
Seismic Data: The Hunger for the Lowest Frequencies Takes Data Gathering in New Directions
The word “broadband” is used to sell a lot of what is new in offshore seismic. It can mean different things depending on who is speaking.
Seismic Data: Faster, Better Seismic Surveys by Making Many Sounds at Once
Companies are using an increasing number of sound shots to gather more data in a shorter time frame.
Seismic Data: Intractable Problem and Big Payoff Sell a Seismic Acquisition Innovation
Developing the Mad Dog discovery appeared to be high-risk because of the difficulty in mapping the subsurface because of the thick layer of salt underlying the region.
The coming year will be challenging for the global geophysical industry and for seismic-acquisition companies in particular.
The Gravity of Oil and Gas Exploration
A Cold War technology invented to stealthily guide the United States Navy’s nuclear submarine fleet is now serving a much more peaceful purpose: aiding in the search for oil and gas deposits.
