Swedish-based international energy firm Tethys Oil has lined up a substantial slate of activities to unlock the hydrocarbon potential of its expanding portfolio of oil and gas assets in the Sultanate.
The Stockholm-headquartered companies operates three of the five blocks in its portfolio, with the remaining two represented by the combination of Blocks 3&4 are operated by CC Energy Development Oman Branch (CCED).
Block 56, located in the southeast of Oman, is planned to be the subject of a three-well drilling campaign during 2021 aimed at further evaluating the Al Jumd area in the north western part of the Block continues. Work on maturing leads to prospects in the Al Jumd area (which includes the Al Jumd discovery) has been completed, Tethys Oil said in his half-yearly report released here on Tuesday. The procurement of equipment and services for the drilling campaign is ongoing. Drilling will aim to establish the commerciality of the Al Jumd discovery as well as confirm the overall productivity of the area. The first well is planned to be drilled in the fourth quarter 2021, it said.
In addition, planning and tendering of a 3D seismic survey in the central area of the Block is also well underway. Final negotiation with a seismic contractor is ongoing. The central area holds a number of attractive leads identified on legacy 2D seismic that warrant further investigation and require more detailed data, it stated.
In Block 49, in the southwest of the Sultanate, the company drilled the Thameen-1 exploration earlier this year. While no flows were recorded at the surface, logs indicated a gross hydrocarbon column of close to forty metres in the primary target, the Hasirah Sandstone.
“The results confirm a decent porosity but a low permeability. Stimulation will most probably be needed in order to try and flow the well, and an unconventional approach could be considered,” the company said.
In Block 58, the company’s most recent acquisition, a new seismic survey is planned for the second half of 2021. In addition, 3D image quality enhancement is planned to be performed on legacy 3D seismic.
Non-operated Blocks 3&4, in which Tethys Oil has a 30 per cent working interest, the exploration well Safi-1 was spudded and reached its final depth in the second quarter of 2021. The exploration well Suhail-1, located between the Erfan and Anan discovery, will be spudded in August 2021. Suhail-1 is targeting the producing Khufai and Buah layers, but will also investigate a new possible stratigraphic trap in the Buah layer.
Significantly, Tethys Oil expects total investments in oil and gas properties of $47 million for 2021, of which investments in Blocks 3&4 are expected to amount to $32 million. The focus of the work program on Blocks 3&4 is continued development drilling, upgrading infrastructure with a focus on asset integrity and debottlenecking, continue the gas utilisation project and the drilling of exploration wells.
The work programme on Block 49 is expected to amount to less than $5 million (following the closing of the EOG farmout) with the main target to complete drilling, testing and evaluation of Thameen-1 exploration well. The work programme on Block 56 is expected to amount to $5 million (on 65 per cent basis including carried interest following completion of the farmin) and is centred on evaluating the Al Jumd area by drilling up to three wells and planning of a 3D seismic acquisition in the central area of the block.
The work programme on Block 58 is expected to amount to $5 million with a focus on reprocessing legacy 3D seismic data and acquiring new 3D seismic, it added.
