Karl Kurz, Anadarko’s COO, said: We are pleased with the results of the drillstem test, which validate the consortium’s updated estimated gross recoverable resources of between 500 million and 1.8 billion barrels of oil. This test confirms the productivity of the large reservoirs in the Jubilee field, and we look forward to working with our partners and Ghana to develop this world-class field.
