All of the oil (C + C) production data for the US state charts comes from the EIAʼ’s Petroleum Supply monthly PSM. After the production charts, an analysis of three EIA monthly reports that project future production is provided. The charts below are updated to August 2021 for the 10 largest US oil producing states.
Overall Norwegian oil production peaked in 2000 but, thanks to the Johan Sverdrup discovery, it is heading for a secondary peak in the next couple of years. Phase I of the development started in 2019 and has design capacity of 440kboed (70kSm3/d) and Phase II is due in late 2022, raising the total capacity to 700kboed of which 535kbpd (85kSm3/d) is crude. The development uses predrilled wills over which the platforms are installed and tied-in, so ramp up was, for Phase I, and will be, for Phase II, rapid. To find a field this size in a mature basin (it is in the North Sea) is unusual, possibly unique so far in offshore oil developments.
For some years Troll has been the largest single oil producer, coming from horizontal oil wells exploiting the oil rim in one half of the field, but recently Troll III was started which produces from the gas cap above the rim, so oil production will now fall.
In the chart green bands are fields in the North Sea, blue-green those in the Norwegian Sea, and the couple of thin blue ones those in the Barents Sea. The 2021 values are only through July.
The OPEC Monthly Oil Market Report for October 2021 was published this past week. The last month reported in each of the charts that follow is September 2021 and output reported for OPEC nations is crude oil output in thousands of barrels per day (kb/d). In the charts that follow the blue line is monthly output and the red line is the centered twelve month average (CTMA) output.
