![]() Prior to then recoverable resource estimates for Avaldsnes were in the range 100-400 million barrels - not enough to get overly excited about. The 16/2-6 discovery well was announced in September 2010, but the story only gained traction on 30th September 2011 when the recoverable resource estimate was substantially increased following evaluation of data from the 16/2-7a sidetrack well. The Aldous Major South - Avaldsnes story has been a year in the making. One of us (EM) owns common stock in Lundin Petroleum. This 3D image shows the Avaldsnes and Aldous Major South discoveries are in all likelihood part of the same giant field. The recoverable resource estimates have grown with every well drilled and with a new delineation well spudded on 28th November, further news on the size of this giant is expected in early January.įigure 1 Oil fields can often be imagined as subterranean hills draped in mudstone (the seal) and partially filled with oil-saturated sandstone. The astonishing thing about this discovery is that it has lain undiscovered in a mature oil province for so long providing ample encouragement for explorers to go on exploring. The Aldous Major South - Avaldsnes discovery on the Utsira High structure is currently estimated to contain 1.7 to 3.3 billion barrels of recoverable oil. With relatively little fanfare on the international stage, Lundin Petroleum and Statoil (and partners) have just recently jointly discovered one of the largest oil fields ever found in the North Sea.
