Saudi Aramco's 2016 oil reserves slip, gas up

KHOBAR, Saudi Arabia (Reuters) — Saudi Aramco said on Thursday its recoverable crude oil and condensate reserves slipped to 260.8 Bbbl at the end of 2016 but its daily crude oil production hit a new record of 10.5 MMbpd.

Aramco's reserves stood at 261.1 B in 2015.

Its gas reserves rose to 298.7 trillion standard cubic feet from 297.6 T, Saudi Aramco said in its 2016 annual review.

The company said it had discovered two new oilfields, Jubah and Sahaban, and one new gas field, Hadidah, all located in the Eastern Province, the main oil region in Saudi Arabia, the world's top crude exporter.

Saudi Arabia's national oil company plans to list a stake through an initial public offering in 2018 which is expected to be the world's biggest IPO.

The review did not make a reference to updates on the IPO process, which is at the heart of Saudi Arabia's economic transformation program.

"For Saudi Aramco, the most notable feature of the Kingdom's transformation will be the future offering of part of the company's shares in local and international stock markets," said Khalid al-Falih chairman of Aramco and Saudi energy minister.

Aramco, which has exclusive rights to explore and develop Saudi Arabia's oil and gas, boosted oil production to a new record of 10.5 MMbpd in 2016, from 10.2 MMbpd in 2015, it said in the review.

Its oil exports rose to 7.6 MMbpd in 2016 from 7.1 MMbpd in 2015. Asia still accounts for the lion's share of Saudi Aramco's exports at 66%, up from 65% in 2015, followed by exports to the United States, whose share dropped to 15.8% from 16.6% in 2015.

Aramco has also raised processing capacity of raw gas to 12 Bscfd.

After raw gas is processed, output of sales gas or methane, used mainly for electricity and petrochemicals, hit a new record of 8.3 Bscfd.

Ethane production, the favourite feedstock for petrochemicals was also higher to 920 MMscfd from 794 MMscfd in 2015.

Saudi Aramco plans to double its gas production to 23 Bscfd in a decade by including "unconventional gas" in the mix and by continuing to develop gas non-associated with oil to help it limit the use of oil in power generation and provide feedstock to the petrochemical industry it is keen to grow.

Its share of chemical production capacity almost doubled to 13,285 ktpy from 7,016 ktpy in 2015 partly thanks to the start-up of commercial operations at Sadara, its joint venture with US Dow Chemical.

Its Wasit gas plant fed by non-associated gas from offshore fields Hasbah and Arabiyah hit full capacity of 2.5 Bscfd. Aramco said more than 40% of non-associated gas now comes from the two fields. Progress continued to be made in the unconventional gas program as the company completed wells in northern Saudi Arabia to deliver 55 MMscfd of gas by year-end 2017 to industrial and electrical power facilities in the Wa'ad Al Shamal industrial city, a phosphate project run by Saudi mining company Ma'aden.

Saudi Aramco has responded to the challenges of the industry by lowering costs of its operations across the board.

As part of technological advancements, it said in the review it implemented new techniques to lower gas production costs such as the use resin-enhanced local sand to fracture a gas well with further trials to follow this year.

Another gas project Midyan is almost complete, it said while on the oil side, the expansion of Arab Light Khurais oilfield to 1.5 MMbpd will be on stream by mid-2018.

Midyan is one of the new gas fields in northwest Saudi Arabia to produce gas for power plants and potentially supply other industries in a region rich in iron ore deposits.

It was discovered in the 1980s and has significant reserves.
