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

SOCO is an international oil and gas exploration and production company, headquartered in London traded on the London Stock Exchange and a constituent of the FTSE 250 Index. The Company has interests in Vietnam, Yemen, Thailand, the Republic of Congo (Brazzaville) and the Democratic Republic of Congo (Kinshasa) with production operations in Yemen.

The Company's majority owned subsidiary, Comeco Petroleum, Inc. ("Comeco"), through which the Company holds a 16.785% net working interest in the East Shabwa Development Area in Yemen ("ESDA"), announces that the KHA 1-16 produced over 8,400 barrels of oil per day ("BOPD") when tested against a 70/64 inch choke. The well was drilled on the eastern most 3D seismic parameter as part of the continuing appraisal and development of the Basement reservoir in the Kharir Field.

The KHA 1-16 spudded on 5th June 2006 and reached a total depth of 3,298 metres measured depth. The objective of the well was to evaluate reservoir development in the eastern extension of the structure as currently mapped. Success with this well extends the Kharir field to the east beyond the current 3D seismic.

Ed Story commented:

"This is significant to the Basement reserves in the Kharir Field that continue to increase. The consortium will evaluate the results of this well to decide upon the approach to accessing the further extension of the eastern part of the Kharir field."
