Swedish producer Tethys Oil said its share of oil production from two onshore operations in Oman, before the government’s take, was more than 12,400b/d in August, about 5% increase from July levels, United Press International reported.

Tethys Oil, the largest onshore license holder in Oman, has a 30% interest in Block 3 and 4 in the Sultanate, with partners Mitsui E&P Middle East at 20% and operator CC Energy Development S.A.L at 50%. The company’s share of production in the oil blocks amounted to 1.09m barrels in the second quarter of 2016, compared with 848,939 barrels in the corresponding period of 2015, according to Reuters.

Oman, the largest oil and gas producer in the region that’s not a member of the Organization of Petroleum Exporting Countries (OPEC),  produced more oil this decade than during the last, thanks in part to enhanced oil recovery techniques, or processes that use steam, gas or chemical injections for further well stimulation. Furthermore, Oman exports around 375bcf/y of natural gas and is a key energy supplier to the Asian economy.
