What’s the largest oil discovery of all time?
That’s the query Rigzone requested David Moseley, the Head of Europe Analysis at Welligence, in a current interview.
Responding to the query, Moseley advised Rigzone that “Ghawar in Saudi Arabia is usually thought-about the biggest standard oil discovery globally”.

A narrative printed in Saudi Aramco’s Components Journal – which was posted on the corporate’s web site in February this yr and penned by Saudi Aramco’s International Communications Specialist on the time, Daniel Hen – said that “the ANDR-1 wildcat nicely, which later led to the invention of the large Ghawar area, is presently each the longest manufacturing run-life and the very best cumulative manufacturing nicely in Saudi Arabia”.
The story highlighted that cumulative manufacturing at ANDR-1 stood at 160.2 million inventory tank barrels.
“Drilling of ‘Ain Dar started in 1948, with manufacturing beginning in 1951 at a rare price of 15,600 barrels per day (bpd) of ‘dry oil’- which incorporates solely a small quantity of primary sediments,” the story famous.
“Though standard wells are recognized to begin producing a better quantity of water quite a few years into industrial manufacturing, the dry oil on the ‘Ain Dar nicely continued to circulation for a staggering 49 years, earlier than it first produced the primary water volumes in 1999,” it added.
“At this time, regardless of it being one in every of our earliest wildcat wells, it continues to ship 2,800 bpd – some 73 years after manufacturing first began on the web site – which is feasible due to the continual adoption of recent, improved extraction applied sciences,” it continued.
“Remarkably, the unique nicely casings are nonetheless in place, showcasing the workmanship and high quality of supplies utilized by our engineers within the Forties,” it went on to state.
When Rigzone requested Moseley if we’re more likely to see one other discovery of Ghawar’s magnitude sooner or later, the Head of Europe Analysis at Welligence advised Rigzone that there’s minimal probability of a standard discovery of comparable measurement being made.
“Whereas massive oil discoveries are nonetheless being made globally, these are order of magnitudes smaller,” Moseley mentioned.
“Such is the dimensions of … Ghawar … [that] making a discovery of this scale in an already confirmed basin, successfully hiding in plain sight, could be past unlikely,” he added.
“A brand new oil discovery over 100 billion barrels would require a completely new, as but unproven basin, with a world class hydrocarbon system in a hitherto undrilled area,” he went on to state.
Welligence is a market intelligence agency centered on the upstream oil and gasoline sector. The corporate delivers technical information and deep evaluation for over 3,000 industrial upstream belongings, whereas overlaying each regional exploration block, Welligence’s web site states.
Aramco describes itself on its web site as “one of many world’s largest built-in vitality and chemical substances corporations, creating worth throughout the hydrocarbon chain, and delivering societal and financial advantages to individuals and communities across the globe who depend on the very important vitality we provide”.
The corporate’s web site highlights that, this yr, Aramco marks its “92nd yr of exploration, discovery, and innovation stemming from our long-term position as caretakers of Saudi Arabia’s huge hydrocarbon assets”.
Aramco states on its web site that it “manages Saudi Arabia’s distinctive hydrocarbon reserves base, optimizing manufacturing and growing long-term worth”. The positioning outlines that this reserves base stands at 250.0 billion barrels of oil.
