Hvis lagret CO2-gass lekker fra reservoarene, er det da mulig å detektere ørsmå mengder på overflaten? Nå skal et forskningsprosjekt finne frem til teknologi, metoder og prosedyrer som kan tilfredsstille både tekniske krav, byråkratiske retningslinjer og en undrende allmennhet.

What has happened to all that crude? Has it dissolved in the water masses? Has it accumulated in the ocean depths? Among those seeking answers are Norwegian researchers at the forefront of modelling oil behaviour in water masses. Read more at sciencedaily.com.
Norge og EU har nå signert den bilaterale samarbeidsavtalen om Galileo. Avtalen legger til rette for full norsk deltakelse i programmet, skriver romsenter.no.
Under dybdekartleggingen i MAREANO måles også de små lokale variasjonene i tyngdekraften. På den måten utnyttes ressursene ved at det samles inn to typer data under ett og samme tokt, skriver mareano.no.
ESA launched the satellite in March 2009 on a mission to map Earth's gravity with unprecedented accuracy and spatial resolution. The first products based on GOCE satellite data are now available online, sciencedaily.com writes.
Forskere og industrifolk har fått et avansert anlegg i stor størrelse der de kan prøve ut ny teknologi for å fange CO2. Bedre kjemikalier og prosesser skal få ned kostnadene, skriver forskning.no.
De siste dagenes begivenheter på Island og i europeisk luftrom har aktualisert behovet for satellittovervåkning av vulkaner og vulkanutslipp, skriver romsenter.no.
A company called 1366 Technologies may have found a way to wafer costs by growing a nearly pure wafer directly from melted silicon rather than forming an ingot that is then sawed, scientificamerican.com writes.
Scientists test the prototype for an instrument that will be a miniature laboratory to discover the composition of rocks and atmospheres on moons, asteroids, and planets across the solar system, in sleeping volcano, sciencedaily.com writes.
Hydratplugger i oljerørene er et økende problem på norsk sokkel. Ny studie kan bidra til fjerne proppene og gi billigere og mer miljøvennlig oljeutvinning, skriver forskning.no.
Sea Bed Logging is a new technology that offers the opportunity to detect trapped
hydrocarbons in the subsurface prior to drilling. Shell EP has recently conducted a number
of very successful data acquisition campaigns throughout the world based on this technology,
leading it to substantially expand its use of this technique in the future.
Reservoir rocks have much lower electrical conductivity
if they are saturated with oil rather than salt water. This
is the principle,well known from borehole logging,
which is exploited in Sea Bed Logging. Ståle Johansen emphasizes
that Sea Bed Logging only
records the electrical conductivity
of the rocks.
Just two years after the very first commercial investigation
we can confirm that the technology functions as
planned. Sea Bed Logging seems to have come up to
expectations achieving what was hoped for but thought
by many to be too good to be true. The oil companies
have, therefore, got a new means of determining whether
oil or gas are present before they decide to drill.
