Bahrain’s new discovery contains 80bln barrels of tight oil

MANAMA: A new discovery off the coast of Bahrain is estimated to contain at least 80 billion barrels of tight oil, the kingdom´s biggest ever find, its oil minister said on Wednesday.

Bahrain said on Sunday it had discovered extensive tight oil and deep gas resources off the west coast of the kingdom.

Independent appraisals by U.S.-based oil consultants DeGolyer and MacNaughton and oilfield services company Halliburton had confirmed Bahrain´s find of "highly significant quantities of oil in place with tight oil amounting to at least 80 billion barrels, and deep gas reserves in the region of 10-20 trillion cubic feet," Oil Minister Sheikh Mohammed bin Khalifa al-Khalifa said.

Tight oil is a form of light crude oil held in shale deep below the earth’s surface that is extracted with hydraulic fracturing, or fracking, using deep horizontal wells. "Agreement has been reached with Halliburton to commence drilling on two further appraisal wells in 2018, to further evaluate reservoir potential, optimise completions, and initiate long-term production," Sheikh Mohammed told a news conference in Manama. He said he was not sure yet how much of the estimated 80 billion barrels was recoverable, but the kingdom aims to attract foreign oil and gas firms to develop the resources.

"The newly discovered resource, which officials expect to be on production within five years, is expected to provide significant and long-term positive benefits to the kingdom’s economy both directly and indirectly through downstream activities in related industries," Bahrain´s National Communication Centre said in a statement.

Sadad al-Husseini, a former senior executive at Saudi Aramco and now an energy consultant, said the discovery was positive news for Bahrain, but more data gathering, evaluation and well testing needed to follow to determine whether there are any future commercial opportunities in the resources.

"Converting resource estimates to reserves is an intense and costly process and not all the resources may ultimately be upgraded to reserves," he said.

"The additional drilling and data gathering will serve to improve the accuracy and reliability of the estimate.
