Swedish energy firm Tethys Oil says it is making headway with its appraisal of the Al Jumd discovery in Block 56 in the southeast of the Sultanate of Oman.
The Stockholm-headquartered firm, which has a sizable portfolio of upstream assets in Oman, said its appraisal programme has commenced with the recent spudding of the Al Jumd-3 well targeting the northeastern area of the Al Jumd discovery.
This will be followed by the Al Jumd-4 well, which will appraise the southern area of the discovery.
The purpose of the two additional wells is to establish resource volumes and determine optimal well productivity levels. The wells will be drilled with the same Schlumberger drilling rig 279 that was used to drill the three preceding wells on the Block earlier in 2022 and, like Al Jumd-2, both wells will be completed with a progressive cavity pump (PCP), Tethys Oil said in a statement.
In 2020, the vertical Al Jumd-1 well flowed at a rate of 100 barrels of oil per day during testing while the horizontally drilled Al Jumd-2 flowed at an initial rate of 700 barrels per day when tested earlier this year. Later in the third quarter 2022, Al Jumd-3 and -4 together with Al Jumd-2 will undergo an extended well test, the company noted.
In the southwest of the Al Jumd area, Tethys Oil is pressing ahead with testing operations of the exploration/appraisal wells Sarha-3 and Sahab-1. Testing of the exploration well Sahab-1 has also recently commenced.
So far, the well has only flowed water as the well is cleaning up following significant mud losses during drilling. Testing and evaluation of these wells will continue throughout the third quarter 2022, it added.
Tethys Oil currently holds interests in Blocks 3&4, Block 49, Block 56 and Block 58 in the Sultanate of Oman.
