GlobalSantaFe's Adriatic VI drilling rig has spudded the North Tano 3X appraisal well in the offshore Ghana North Tano Field (Block Tano Shallow). The North Tano 3X well will be drilled as a deviated well targeting Cretaceous sands at approximately 2000 meters subsea. The drilling and potential testing of the well is estimated to take approximately two months and the total cost including testing is budgeted to be USD 31 million.

The North Tano Field was discovered in 1970, 12 km from the shore in 54 meters water depth. It is a gas field with an oil rim, penetrated by 3 wells, testing up to 8.3 mmscf/d and 300 - 900 bopd of light oil.

InterOil has a 31,75% working interest in Tano Shallow and has the same interest as the operator Tullow Oil. The remaining JV partners include Thani Ghana (22%), Sabre Oil (4.5%) and the Ghana National Petroleum Corporation (GNPC) with 10% carried interest.
