BP spearheaded new industry technology in the late 1980s that improved seismic imaging and enabled oil production in the region to increase from virtually nothing in the early 1970s to over 3 million barrels per day within 10 years. The Ula field in Norway began production in 1986 with an expected life of only 11 years, but additional surveys found 400 million more barrels of potential reserves and BP used new technology to further unlock the field's potential, allowing it to still be producing as of 2028. In 1983, the Magnus platform began producing oil off the coast of the UK and was the largest and deepest steel platform ever installed in the North Sea at that time.
