Sea bed logging (SBL) is a marin operation using a vessel deploying receivers on the sea floor. The source for the electromagnetic waves is towed behind the vessel and is some 300m long. Doing a survey with one single line can take from a few days up to one week. To the right we see results from a survey on the Troll field.
Proving the concept
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.
