The company said the well has reached total depth and encountered one hydrocarbon-bearing sand, having an estimated 3 to 3.5 metres (10 to 12 feet) of net gas pay.
Production casing will be set prior to suspending the well for future completion. It was drilled to 1082 metres total vertical depth in 42 metres of water.
Petsec has 100% of the well, located 105 kilometres (65 miles) south of Cameron Parish, Offshore Louisiana in the Gulf of Mexico.
Petsec is expecting to drill a second well from this same location, the Vermilion 258 #G-7 well, which is expected to spud within the next 2 – 3 days.
