According to the world energy news on February 17, a study shows that more than 60% of the oil and gas discovered in 2019 came from offshore areas, a significant increase compared with previous years.
According to the global data report, Colombia and Norway found the most oil reserves in 2019, while Guyana, Mauritania and Russia had the most important oil discoveries. In Guyana, ExxonMobil drilled five new discoveries in the deep-water starbrook block. After drilling a new well (uaru-1) in January 2020, the company has increased the estimated total recoverable resources of the block to more than 8 billion barrels of oil equivalent.
Tullow also contributed to the country’s success in 2019, drilling Jethro (deep water) and Joe (shallow water) wells in the stabrook block.
“The discovery of Guyana in 2019 is based on the success of previous years, some of which have been put into production,” said Toya Latham, an oil and gas analyst at global data. Previously, in December 2019, Liza phase I development project, as the country’s first large-scale oil project, was put into operation, and completed the development less than five years after its discovery. The region has also recently achieved greater success, with total reporting the discovery of significant oil in block 58, which is located in Suriname and adjacent to the stabruk block. ”
Natural gas has been found in Mauritania and Russia. In November 2019, BP announced the success of its deepwater orca-1 well in Mauritania. The well is targeted at the orca exploration area, where the initial average gas reserves are estimated to be 13 trillion cubic feet. In early May 2019, Gazprom also confirmed that its total reserves of two wells (dinkov and nyameskoye) drilled in the Kara Sea continental shelf are estimated to be 1.5 billion barrels of oil equivalent.
Latham added: “the orca-1 well in the northern part of block C8 complements the recent successful drilling activities in the area and supports BP’s plan to build the area into a regional LNG center. The company has approved the first phase of a cross-border greater tortueahmeyim development project in the south of the block, and the latest findings in the north of the block will help support any expansion plans in the bir Allah area. ”
