30-06-08 India's Oil and Natural Gas Corp (ONGC) and GAIL (India)'s equity in two gas rich offshore blocks in Myanmar have been cut following Myanmar's national oil company exercising its "step-in" rights in the fields, gas from which will be sold to China.
ONGC had a 20 % stake and GAIL a 10 % stake in the A-1 and A-3 offshore blocks, where independently certified reserves are put at 4.53 tcf.

South Korean trading company Daewoo International Corp was the operator with 60 % stake and Korean Gas Corp (KOGAS) had the remaining 10 %.
However, as per the production sharing contract for the field, Myanmar Oil and Gas Enterprise (MOGE) had a "step-in" right to take 15 % stake once discoveries are made.
