Seismic Data Acquisition
The initial discovery well was sited using 2D seismic reflection data. In 1982, the first 3D seismic dataset was acquired over Oseberg, to assist with continuing exploration and appraisal drilling. In 1989 and 1991 Statoil acquired two sets of 3D data over the field, using the same parameters, as a feasibility study for a full 4D seismic study. Following the success of the pilot study, additional surveys were shot in 1992, 1999, 2004 and 2007. These surveys are used to actively monitor changes in the gas-oil contact and the water-oil contact as production continues.

Famous quotes containing the words seismic, data and/or acquisition:
“Most near, most dear, most loved and most far,
Under the window where I often found her
Sitting as huge as Asia, seismic with laughter,”
—George Barker (b. 1913)
“This city is neither a jungle nor the moon.... In long shot: a cosmic smudge, a conglomerate of bleeding energies. Close up, it is a fairly legible printed circuit, a transistorized labyrinth of beastly tracks, a data bank for asthmatic voice-prints.”
—Susan Sontag (b. 1933)
“Wars and revolutions and battles are due simply and solely to the body and its desires. All wars are undertaken for the acquisition of wealth; and the reason why we have to acquire wealth is the body, because we are slaves in its service.”
—Socrates (469–399 B.C.)
