ObliQ Technology Improves Seismic Imaging
In a marine geophysical survey, every attempt is made to maintain the streamer at a constant optimum depth. But there are issues involved in selecting that optimum depth; too shallow,…
Cableless Confusion
As the cableless seismic market grows it appears that the most flexible systems will be the winners. After almost a decade of nearly taking off, this flexible new technology is…
Effective Data Management Maximises Subsurface Asset Values
An Exploration and Production organisation generates vast amounts of data in order to define and value its subsurface assets. But ultimate value will only be maximised if critical business decisions…
Going Deep for the Heat
Geothermal energy is becoming an increasingly hot topic. Recent research suggests that even areas outside ‘high-temperature fields’ may be sufficiently warm to generate electricity. Beneath our feet there are rich…
Does Geology Last Forever?
The Earth’s resources have been exploited by humans for many thousands of years, but we need to ensure that the integrity and accessibility of important sites and landscapes in the…
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…
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…
