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.
