Recently, we have seen falling oil prices combined with sticky costs at a high level in the petroleum industry. This causes project postponements, thus challenging reserve replacement of oil companies and security of supply for consumers. Costs are particularly high for drilling. High rig rates are obviously important. In addition we experience a dramatic fall in drilling productivity. This paper analyses the development in drilling productivity in exploration wells at the Norwegian continental shelf. A unique data set allows us to apply econometric analyses to ascertain vital explanatory factors for variation in drilling productivity over time and between different wells. 1-2 Journal of Petroleum Science & Engineering 73 ARTICULO Osmundsen, P. 46353 Roll, K.H. 46884 Tveterås, R. 46885 177001 177001 0 0 0 0 244820 BAAB BAAB 2026-03-05 200048936 0 200048936 2026-03-05 18:58:06 2026-03-05 ARTICULO
