Tethys Oil begins drilling operations on Block 49 onshore Oman

AdobeStock 181961238Oman's Tethys Oil has commenced the drilling operations of exploration well Thameen-1 on Block 49, planned to be drilled to a depth of about 4,000 m below ground

Primary target is the Late Ordovician Hasirah Sandstone layer at a depth of 3,500 m (TVD). A secondary target is the Mid-Ordovician Saih Nihayda Sandstone at a depth of 3,700 m (TVD). In addition, the well will also investigate the shallower Gharif Sandstone

“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,” said Magnus Nordin, managing director of Tethys.

Block 49 is an onshore block that covers 15,439 sq km in the South West of the Sultanate of Oman within the Governate of Dhofar. The drill site is located within the northern part of the block, at Marsudad village in the Wilayat of Muqhsin. Tethys Oil, through its wholly owned subsidiary Tethys Oil Montasar Ltd, has signed a contract with Abraj Energy Services SAOC for the provision of the Abraj-204 drilling rig. 

Tethys Oil entered into a farmout agreement with EOG Resources (EOG) in November 2020, whereby EOG acquired a 50% 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% of the licence interest.
