Tethys Oil starts drilling activity on Block 49
Swedish energy company Tethys Oil last week announced that the drilling operations of its exploration well Thameen-1 on Block 49 onshore Oman has commenced.
The well is planned to be drilled to a depth of about 4,000m below ground and drilling operations are expected to last about 45 days, the company said in a statement on its website.
“We are delighted to have started drilling operations on Block 49. The Thameen-1 well is designed to penetrate several potentially hydrocarbon bearing rock layers. We have three defined targets, but we will analyse all data from the well to increase our understanding of the potential oil plays in the block, conventional as well as unconventional,” Tethys Oil’s managing director Magnus Nordin said.
Tethys Oil said its primary target for exploration well Thameen-1 is the Late Ordovician Hasirah Sandstone layer at a depth of 3,500m. A secondary target is the Mid-Ordovician SaihNihayda Sandstone at a depth of 3,700m. In addition, the well will also investigate the shallower Gharif Sandstone.
The drill site is located within the northern part of Block 49 at Marsudad village in the Wilayat of Muqhsin. Block 49 is an onshore block that covers 15,439 sqkm in the South West of Oman within the Governate of Dhofar. Tethys Oil, through its wholly owned subsidiary Tethys Oil Montasar Ltd, has signed a contract with Abraj Energy Services for the provision of the Abraj-204 drilling rig.
Tethys Oil entered into a farmout agreement with EOG Resources in November 2020, whereby EOG acquired 50 per cent interest in the exploration and production sharing agreement covering Block 49. The agreement is subject to government approval. Tethys Oil AB, through Tethys Oil Montasar Ltd, is the operator of the Block and holds 50 per cent of the licence interest.
