Marine Seismic Sources Part XIII: The Far Field Response of an Air Gun Array
“Why do we love the sea? It is because it has some potent power to make us think things we like to think.” Robert Henri (1865-1929), American painter and teacher…
Technology
The Age of Uncertainty
Maximizing resolution from integrated seismic and quantitative biostratigraphy using CONOP Biostratigraphic correlation based on the geological succession of fossil species remains one of the fundamental workhorse approaches to geological correlation…
Emphasizing Vibrations
CGGVeritas is applying new technology to extend seismic bandwidth and maximize production. In the article ‘Illuminating Resolution’ (GEO ExPro Vol. 8, No. 3) we described the evolution of seismic acquisition technologies that…
Putting the Pieces Together – Interactive Tabletop Visualization
Digital tabletops provide a true collaborative environment for reservoir analysis that often requires a varied input from different fields of expertise. Remember dumping 1,000 varied shaped and colored pieces on…
Central Asia: Cutting Edge Technology in Frontier Exploration
Central Asia represents an exciting frontier for oil exploration, from sub-salt to sub-thrust exploration. The region remains a hive of activity, boasting some of the largest oil and gas fields…
What is Tight Gas?
Since its production is tied to technological developments, well cost, and fraccing gas prices, tight gas is an economic issue A practical definition of a tight gas field at present…
The Zagros uplift
“We climbed for most of that day, conquering step by step the Morvarid Pass, only to drop down again, having reached the top; and as evening fell we came down…
Advances in Deepwater Reservoir Monitoring
With the market for Permanent Reservoir Monitoring (PRM) continuing to grow along with deepwater field expenditure (Douglas-Westwood forecasts global deepwater CAPEX of US$225 billion between 2011 and 2015), TGS company,…
Marine Seismic Sources Part XI: Effect of Seismic on Crabs
In previous editions of GEO ExPro we have discussed the effect of seismic shooting on mammals and fish. What about animals without ears, like the crab? In this article, we…
Solving Hydraulic Fracturing ‘Controversies’
Hydraulic fracturing has unlocked a vast, new oil and gas resource from very tight rocks. Innovative developments in nanotechnology are poised to make hydraulic fracturing more efficient, accountable, and much…
Marine Seismic Sources Part X: Seismic Surveys and Fish
The possible effects of seismic surveys on fish and fisheries have been given a great deal of media attention in Norway. Here, we summarise results from the Fish Rock experiment…
Gas Hydrates – Part I: Burning Ice
Scientists have known and studied natural gas hydrates for decades. Vast deposits of hydrates have been found, both in the permafrost and the continental shelves of the oceans of the…
