Masirah Oil Limited, which operates Block 50 offshore Oman’s east coast, announced that the Yumna-4 Deep appraisal / exploration well in the Yumna Field had been spudded earlier this week. The well is being drilled by Compact Driller, a medium-class jack-up rig from Shelf Drilling.
Yumna-4 Deep will be a dual-objective directional well. The shallow objective will be to test the eastern extension of the Yumna Field which is productive from the Aruma Formation at about 1,700 metres. After reaching the Aruma, the well will be deepened to the exploration objective which is a structural closure in the Khufai Formation at about 3,000 metres. The Khufai Formation is productive onshore Oman but is under-explored in the offshore area.
Drilling operations for the Yumna-4 Deep well are expected to be completed in about 60 days. The Yumna-4 Deep well will be drilled from the Mobile Offshore Production Unit (MOPU) in the Yumna Field.
