A total of 72 companies participated in 74 high impact wells through the year.
Repsol and Eni, who both have stringent net zero targets, fell out of the list of most active explorers, participating in 3 each, Westwood said.
High impact drilling saw discovered resource of just 6.6 billion barrels of oil equivalent in 2021, down from 19 billion the prior year.
This was dominated by a small number of large discoveries in Russia, accounting for 48% of the total at 3.2 billion barrels.
The largest of the year was the Zinichev discovery onshore, with 2.3 billion, from Rosneft and BP.
2022
In 2022, Westwood predicts the hot spots for drilling will mostly be in South America, particularly the Suriname-Guyana basin an offshore Brazil, along with the Gulf of Mexico and some key wells in eastern Canada.
The combined resource potential from wells to be drilled, or considered firm or probable wells by Westwood, this year is estimated to be around 30 billion barrels of oil equivalent.
