Operated by Pan Orient Energy (Siam) Limited, Sea Oil Public Company ("the Company") reported the exploration and production updates as follows. L53-DD9 appraisal well was drilled during October-November. Oil was discovered in 4 main intervals (AA, BB, CC and DD) with a total vertical thickness of 29 meters. The CC sand interval is 18.4 m. thick vertically, much thicker than all other producing sands within the DD structure. The L53-DD9 well is within the existing production area and can be put onstream after completion within the next 10 days. Other planned appraisal wells have been postponed to mid-February 2021. The recently drilled L53-DD8 have been put onstream but will be turned into water disposal well to inject water produced from all producing wells within the DD structure. This will significantly save operating expenses from water production treatment and truck delivery to dispose in wells in other distant areas. Other currently suspended wells L53-DD4 and L53-B1 for workovers will be put on production by the end of 2020. Under the current world oil price, the Joint Venture has held up drilling program but instead, focused on field development and production to enhance the overall performance and the annual reserve assessment of the entire Block L53/48 at the year-end.
