Tethys Oil Oman Onshore Ltd. received fiscal metering equipment for the extended well test on the Al Jumd discovery in the northwestern corner of Block 56 onshore Oman. The equipment is at the hook up point, and installation is ongoing. Commissioning and first oil are expected before Mar. 24.
The extended well test has a planned duration of 3-6 months with the objective of establishing recoverable resources volumes and optimal production rates.
Production rates during the test are expected to vary due to test considerations and data-gathering objectives. Initial export production is expected to be about 400 bo/d and shortly thereafter increase to 800 bo/d. The oil will be transported about 15 km by truck from the production facility at Al Jumd to Simsim, where the oil will be unloaded and measured by the fiscal meter before transfer into the national pipeline system.
Production and operating costs relating to the extended well test are not included in the scope of Tethys Oil’s production and financial guidance for 2023.
Tethys Oil acquired 2,000 sq km of 3D seismic in 2022, covering more than a dozen leads identified on legacy 2D seismic. Processing has been completed and delivered to the company which has started interpretation. The objective of interpretation is to identify mature drillable prospects ahead of exploration drilling planned to start fourth-quarter 2023.
In early 2022, Tethys Oil drilled the horizontal Al Jumd-2 with positive results and an initial flowrate of about 700 bo/d. Following the positive results of Al Jumd-2, the appraisal program was expanded by an additional two wells, Al Jumd-3 and -4, in third-quarter 2022. Al Jumd-2, -3, and -4 were drilled in the structure’s northwestern, northeastern, and southern areas, respectively, and cover a large portion of the discovery.
Tethys Oil is operator of Block 56 (65%) with partners Biyaq Oilfield Services (25%), Intaj LLC (5%), and Medco Arabia Ltd. (5%) (OGJ Online, Oct. 28, 2020).
