Abu Dhabi National Oil Company on Tuesday announced the discovery of Murban oil resources at its onshore block 4, operated by Japan’s Inpex. Block 4 covers an area of 6,116 square kilometres and stretches from Abu Dhabi city to the border with the emirate of Dubai. The exploration well was drilled following a combined onshore and offshore 3D seismic survey. It will now be appraised to further quantify the resources, which are estimated to reach 1 billion barrels of oil equivalent.
Inpex and Jodco operate Block 4 with a 100% interest, but ADNOC has the option to take a 60% stake during a potential production phase of the concession. The block consists of two existing undeveloped oil and gas fields named Ramhan and Hudairiat. It is also close to the onshore oil-producing fields of al-Dabb’iya and Rumaitha, as well as the offshore Umm al-Dalkh field.
Earlier in December, ADNOC revised up its conventional oil reserves estimate by 4 billion barrels to a total of 111 billion barrels. More than half the new reserves are Murban-grade, the company’s flagship light sour crude grade. It also added another 16 Tcf of natural gas, bringing its total gas reserve to 289 Tcf.
