Renewed Interest in CSEM in Oil and Gas Exploration
Controlled Source ElectroMagnetic (CSEM) is a proven technique that has a strong future in helping solve certain oil and gas exploration and production challenges, especially when seismic data alone cannot…
Marine Site Investigation and Reducing Risk
The evolving role of seismic reflection data within offshore site investigation. Marine site investigation is, at heart, about reducing risk. Sometimes it involves minimizing the risk to operations posed by…
Who Needs Geoscientists?
At the time of writing, the world is enduring the effects of the Covid-19 pandemic, and the global economy is struggling. Nonetheless, we should look ahead to a brighter future…
Are Carbonate Reservoirs ‘Difficult’?
Up to 60% of the world’s conventional petroleum is reservoired in carbonate rocks – but they are often regarded with apprehension by the industry. Despite their reputation, carbonate reservoirs are…
Seismic Data Collection Using Vibroseis Technology
The modern vibroseis is a complex, delicately tuned machine. The shaking gets translated into seismic data to provide insights into the subsurface for oil, gas and resource exploration. An 80,000…
Exhumed Portuguese Oil Field Suggests Hydrocarbon Potential in Conjugate Newfoundland Basin
The discovery of an exhumed oil field in the central Lusitanian Basin in Portugal has significantly enhanced the hydrocarbon potential of Lusitanian and Peniche Basins and the conjugate Carson-Bonnition Basin…
Advancing Geophysical Interpretation in Oil and Gas Exploration
Geophysics must change – but it must also remain meaningful. “Geophysical data are a part of everything that we do,” Stephen Greenlee, president of ExxonMobil Exploration Co., told a roomful…
An Introduction to Geomechanics
Geomechanics is the study of how subsurface rocks deform or fail in response to changes of stress, pressure and temperature and it is becoming increasingly important in oil and gas…
Artificial Intelligence and Seismic Interpretation
The key to all seismic interpretation is the interpreter’s experience and knowledge, so why should artificial intelligence change that? The reality is, it shouldn’t. Figure 1: Exmouth Basin section with…
The Future of Marine Seismic Acquisition
Some thoughts on the future of marine towed streamer seismic acquisition for offshore oil and gas exploration. Polarcus XArray™ Triple source acquisition. © Polarcus. Seismic acquisition and exploration technology have…
One Step Closer to Fully Automated Fault Extraction in 3D Seismic Data
To boldly go where no interpreter has gone before To Boldly Go Where No Interpreter Has Gone Before The Last Frontier in Seismic Interpretation: Automatic Fault Detection The Exmouth Basin…
