LARGEST DISCOVERIES BY COUNTRY IN 2018

Rystad Energy recently highlighted the largest discoveries by country in 2018. 2018 stands already as the best year for global oil and gas exploration since 2015. In total we expect discovered resources in 2018 to surpass 9.4 billion barrels of oil per day (boe) by year-end, where offshore makes about 82% of the volumes.
Rystad Energy estimates combined recoverable resources of around 728 million boe from these two discoveries.
• Offshore Guyana, ExxonMobil registered its tenth discovery in the prolific Stabroek block, boosting its recoverable resources from the block to about 5 billion barrels of oil equivalent.
• Offshore Russia, Novatek drilled its first exploratory well in the North Obskoye block in the shallow waters of Ob Bay. This is the largest discovery to date this year and is estimated to hold recoverable resources of around 960 million barrels of oil equivalent.
• In the US Gulf of Mexico, Chevron and Shell registered oil discoveries in the Ballymore and Dover prospects. Rystad Energy estimates combined recoverable resources of around 728 million boe from these two discoveries.
• Other relevant discoveries included Eni’s Calypso gas discovery offshore Cyprus, Petroleum Development Oman’s Mabrouk North East gas/condensate discovery in Oman and Quadrant Energy’s Dorado oil discovery in Australia. The Calypso discovery confirmed the extension of a play in the Cyprus Exclusive Economic Zone that resembles the giant Zohr field to the south in Egyptian waters, and Dorado was one of the largest discoveries ever in Australia’s North West Shelf. Rystad Energy estimates that these fields hold cumulative recoverable resources of around 1.6 billion boe.
Exploration spending decreased by nearly 61% from 2014 to 2018. Exploration investments halted their fall in 2018 and are expected to rise in 2019.
“This not only proves that E&P companies are once again willing to invest in exploration, but also highlights their idea of ’smart investments’ to de-risk expenditures as much as possible,” Rystad said.
The decrease in overall exploration costs combined with an improved success ratio have led to tremendous improvement in the discovery cost per boe. (Source and image: Rystad Energy)
