Limestone and dolomite reservoirs of the Middle East have fairly good porosity and permeability. In Saudi Arabia's Ghawar field (the world's largest oil field), two producing members (C and D) of the Arab Formation, have thicknesses of 30m and 80m respectively, and a porosity of 20%.
The price of oil has collapsed, storage will rapidly run out, and oil companies face the real prospect of having to cap wells. The oil and gas sector accounts for up to 50 percent of the kingdom's gross domestic product and 70 percent of its export earnings. This has just disappeared.

Not exactly. We're much less dependent on Middle East oil than we used to be, yes, but not entirely so—and in fact, we can't be. Because of the global connectedness of oil markets, the U.S. still imported about 9.94 million barrels of petroleum in 2018 from 90 different countries.
In 2019, Canada was the source of 49% of U.S. total gross petroleum imports and 56% of gross crude oil imports.

Globally, we currently consume the equivalent of over 11 billion tonnes of oil from fossil fuels every year. Crude oil reserves are vanishing at a rate of more than 4 billion tonnes a year – so if we carry on as we are, our known oil deposits could run out in just over 53 years.
The 2019 edition of the BP Statistical Review of World Energy reports the total proved reserves of 303.3 billion barrels for Venezuela (slightly more than Saudi Arabia's 297.7 billion barrels).
There are 266.2 billion barrels worth of oil in Saudi Arabia, by far the most of any OPEC nation and the second most of any country in the world.
Without oil, cars may become a relic of the past. Streets may turn into public community centers and green spaces filled with pedestrians. Bike use might increase as more people ride to school or work. The Earth will begin to heal from over a century of human-caused climate change.
Middle East countries could run out of money long before they run out of oil, according to a stark warning issued by the International Monetary Fund (IMF) in a report today. That means the clock is ticking for Gulf oil exporters to fundamentally rebalance their economies.
In total energy consumption, the US was between 86% and 91% self-sufficient in 2016. In May 2011, the country became a net exporter of refined petroleum products. As of March 2015, 85% of crude oil imports came from (in decreasing volume): Canada, Saudi Arabia, Mexico, Venezuela, and Colombia.
The Manifa Drilling Team set a new record in December when it finished drilling the longest well in Saudi Arabia to a total depth of 32,136 ft (± 9.8 km) and completed a horizontal power water injector across the Lower Ratawi reservoir.
In the 1930s, Chief geologist at Casoc and Aramco expat, Max Steineke revolutionised hydrocarbon exploration in the Middle East using structure drilling - which led to some of the first discoveries of oil in Saudi Arabia.
Originally Brent Crude was produced from the Brent oilfield. The name "Brent" comes from the naming policy of Shell UK Exploration and Production, operating on behalf of ExxonMobil and Royal Dutch Shell, which originally named all of its fields after birds (in this case the brent goose).
The earnings of Saudi Arabia's giant oil company have long been a mystery, kept under wraps by the country's government. But on Monday, Saudi Aramco opened its books, revealing that it generated $111.1 billion in net income last year, making it probably the world's most profitable company by far.
The economy of Saudi Arabia is heavily dependent on oil, and is a member of OPEC. In 2016 the Saudi Government launched its Saudi Vision 2030 to reduce the country's dependency on oil and diversify its economic resources.
