Brazil’s OGX expects each production well from the Gaviao Real field in the onshore Parnaiba basin to produce around 700,000 cubic metres per day of natural gas, writes Fabio Palmigiano.
OGX started drilling the first development well at Gaviao Real in Block BT-PN-8 in September, using the Queiroz Galvao-owned QG-1 land rig.
“Additional data obtained from the drill stem test carried out at the GVR-1D well indicates that the well has a production potential of up to 3.5 million cubic metres per day in absolute open flow, but we intend to produce around 20% of that from each well,” said OGX exploration & production director Paulo Mendonca.
In May, OGX declared commercial two natural gas discoveries in the north-east Parnaiba basin — the California and Fazenda Sao Jose accumulations were renamed as Gaviao Azul and Gaviao Real.
Output from the two fields is earmarked to begin in the second half of 2012, rapidly ramping up to a gross flat production rate of 5.7 MMcmd by 2013.
