SOCO International plc
("SOCO" or "the Company")

The Company's majority owned subsidiary, SOCO Vietnam Ltd., announces the preparation for the commencement of drilling of the first Clastics targeted well on Block 9-2 with the imminent spudding of the Ca Ong Doi 2X ("COD-2X") well. The drilling rig is on site after an extended weather delay whilst it was awaiting to be towed from the Te Giac Trang 5X well on Block 16-1, which tested at a total combined maximum flow rate of approximately 16,430 barrels of oil equivalent per day.

The COD-2X well is designed to evaluate the Clastics reservoirs that have been successfully tested on Block 16-1. It is anticipated that this well will take approximately 40 days to drill. Testing, if required, would add several weeks. The spudding of this well will mark the beginning of the most active annual drilling programme in the Company’s history.
