Why The Permian Basin May Become The World's Most Productive Oil Field

...But I am becoming more convinced that the Permian Basin could eventually give Ghawar a run for its money....

...Permian Basin oil production slowly crept back up to one million BPD in 2010, and then hydraulic fracturing sent production soaring. By the end of 2018, production had reached 3.8 million BPD, vaulting the Permian into second place among the world's leading oil fields. In under a decade -- and after already producing oil for a hundred years -- Permian Basin production has increased by 3 million BPD:



...Consider the soaring inventory of drilled but uncompleted (DUC) oil wells. These are oil wells that have undergone the initial process of drilling (i.e., the hole in the ground has been drilled). However, to get the well ready for production requires casing, cementing, perforating, and hydraulic fracturing.

There are a number of reasons that a well might be drilled, but not completed. It can be as simple as a lack of available rigs and manpower to complete the wells. Or, it could be that producers are waiting for more takeaway capacity for the oil, which has been an issue in the Permian. Finally, some contracts may require that drilling has been initiated in order to hold a lease.

Regardless of the reason, DUC wells generally turn into completed wells. And the inventory of DUC wells suggests that Permian Basin production still has a lot of room to run. At the end of 2013, there were 636 DUC wells in the Permian Basin (when oil production there was 1.4 million BPD). By the end of 2018, with Permian Basin production at 3.8 million BPD, the number of DUC wells had soared to 4,039....



...The new estimated mean of undiscovered, technically recoverable resources in the Permian basin are 46.3 billion barrels of oil, 281 Tcf of natural gas (17.5 times higher than the 2016 estimate!), and 19.9 billion barrels of NGLs....

How An Oil Boom in West Texas Is Reshaping the World
http://time.com/5492648/permian-oil-boom-west-texas/
1/3/2019

...This year the region is expected to generate an average of 3.9 million barrels per day, roughly a third of total U.S. oil production, according to the U.S. Department of Energy. That’s enough to make the U.S., as of late 2018, the world’s largest producer of crude. The windfall has turned a nation long reliant on foreign oil into a net exporter in a few short years.

Not even the plunge in oil prices in recent months, which led some companies to scale back their plans for the Permian, has stopped the enthusiasm. Analysts predict the region’s output will expand in coming years, thanks to cost-reducing advances in hydraulic fracturing, better known as fracking, to release oil from shale, plus changes in U.S. export policy. By 2025, U.S. oil production is expected to equal that of Saudi Arabia and Russia combined, according to the International Energy Agency (IEA).

The power of the Permian oil and gas boom is easy to spot in the basin itself, which stretches across more than 75,000 sq. mi. of scrubby ranchland in West Texas and New Mexico. So-called man camps–hastily constructed short-term housing for oil-field workers–have sprung up everywhere, amid new luxury construction projects and shiny billboards advertising Rolexes to laborers pulling in six-figure salaries. But the impact extends far beyond the region.

During the past three years, the boom in these parts has transformed the U.S. economy, upended the international energy industry, undermined global environmental efforts and tilted the balance of power among Beijing, Moscow and Washington. In places like Saudi Arabia, uncertainty over future oil profits driven by rising U.S. production contributed to a rethinking of the economy. In theory, less reliance on Saudi oil also gives the U.S. more leverage in other areas, like the war in Yemen, although the Trump Administration hasn’t prioritized such efforts. The vast new U.S. oil reserves have provided cover for the imposition of tough sanctions against nations like Iran and Venezuela, moves that at other times might have crippled global supply. And around the world, the boom in the U.S. has inspired other countries to race to develop their own shale resources. “In a shale revolution world, no country is an island,” says Fatih Birol, who leads the IEA. “Everyone will be affected.”...

For comparison, this is larger than ANWR, Central North Slope and NPRA (Alaska) all put together.

I'm not aware of the practice of leaving uncased holes lying about. I strongly suspect that all of these wells need to get ready for production are perforating an fracturing along with the infrastructure to handle the resulting production.

I agree, the DUCs have casing and cement already done.

This sounds all well and good, but to call the entire Permian basin  a 'field' is ridiculous.  No geologist that I know would.

Why not call the Middle East basin a 'field'?  It would beat out the Permian by a magnitude in terms of recoverable oil.
