Tethys Oil encounters hydrocarbons on Block 49 onshore Oman

Swedish oil company Tethys Oil has made hydrocarbons discovery at the Thameen-1 exploration well located on Block 49 onshore Oman.

The firm has drilled the exploration well Thameen-1 to its final total depth and completed wireline logging operations.

Following drilling, the well has encountered hydrocarbon shows in Hasirah Sandstone, which is the primary target.

In an effort to assess the well, the company plans to start a well testing programme within three weeks, with an aim to flow the discovered hydrocarbons to surface.

Tethys Oil managing director Magnus Nordin said: “This is not a discovery yet, but we are very encouraged by the progress so far and it is great news for the overall prospectivity of the block. Now we have to be patient for another three weeks as we await the test results.”

Covering an area of 15,439 km², the Block 49 is in the South West of the Sultanate of Oman. The block was awarded to Tethys Oil in 2017.

Tethys Oil Montasar, a wholly owned subsidiary of Tethys Oil, operates the Block 49. It also owns a 50% stake in the exploration and production sharing agreement covering the block.

In November 2020, Tethys Oil signed a farm-out agreement with EOG Resources’ wholly owned subsidiary EOG Resources Oman Block 49 for the onshore Block 49.

Under the agreement, EOG Resources agreed to acquire a 50% stake in the exploration and production sharing agreement covering Block 49.

EOG will also have the option to increase its stake to 85% and take over the operations of the block.
