A new gas-processing plant was commissioned in Saih Nihayda in 2005, and another one is due in 2008 for PDO's newest gas field in Kauther. With the addition of those two processing plants, nearly one-third of the hydrocarbon energy that PDO supplies will come from natural gas—the fuel that has a central role in the Government's economic diversification plans. Faced with oil prices above $100 a barrel and sinking field capacities, PDO was one of the many companies to introduce in-site combustion, an enhanced oil recovery technique involving lighting fires within the reservoirs, in 2008. In 2010, the company announced the discovery of three new oil- and one gas field. Since 2010, PDO has been working on the Miraah Solar Project, a 1,021 megawatt solar thermal facility, which is to be used in EOR from 2017/2018 onwards. In 2011, a series of strikes and protests took place in Oman that also involved hundreds of PDO workers demanding higher wages. Since the decline of natural production capacity, PDO has invested heavily to keep up and try to increase production again. Having to rely on marginal wells and enhanced oil recovery techniques more and more, the overall quality of oil is getting heavier and drifting down said the director of Purvin & Gertz, an international energy consulting firm, in 2011. In 2013, a team of members from Manpower Ministry and Oman's Trade Union Federation found nearly 50 labor law violations and mistakes in safety norms during an inspection at PDO's Fahud facilities. In 2014, P. Mohamed Ali, the former managing director of Galfar Engineering and Contracting, was sentenced to three years in jail for bribes made to PDO. In the same year Juma Al Hinai, the former head of the tender committee at PDO, was also charged with bribery and sentenced to three years in jail, including a fine of 600,000 rials. He was banned from public office for 20 years. Subsequently, the head of PDO warned all contractors to adhere to anti-bribery and -corruption policies. In 2016, PDO launched a $3.4 billion loan program with HSBC bank. In the same year, PDO signed a contract with GE Oil & Gas to provide Progressive cavity pump (PCP) equipment and related services from late 2016 onwards. In 2017, following many years of reconstruction and oilfield optimization, PDO confirmed a new combined oil, gas and condensate production record (1.293 million barrels of oil equivalent
