The company told the market today that the 9-inch casing will be perforated tomorrow morning, after which it will production test the gas charged zones of the Epenarra structure.
The decision to production test this formation was based on strong indications of a significant gas accumulation in drilling, electric logs and core sample interpretation.
Heron-2 is a follow-up to the Heron-1 well drilled by ARCO in 1972 which intersected a 52m gas-bearing column in the Darwin Formation (a fractured carbonate reservoir) within the 1200 square km mapped closure of the large Epenarra structure.
The exploration well reached a gas-charged zone in the deeper underlying Elang-Plover horizon.
