By GlobalDataDrilled last year, the first SM71 well logged 151ft of oil pay in four zones.
Independent reserve assessment prepared by Collarini Associates attributed a total of 2.271 million barrels equivalent net to Byron on a 2P basis to SM71 F1 well, with a majority procured from D5 Sand.
The secondary target of the SM71 F2 is the B65 Sand, which lies above the D5 sand, where the well will test the prospective resources attributable to it.
Collarini attributed 2.042 million barrels of oil and two billion cubic feet of gas net to Byron from the B65 Sand.
The drilling programme is expected to take less than 30 days, while production is expected to start from January next year.
Byron Energy holds a 50% working interest in South Marsh Island Block 71 with the operatorship, while Otto Energy owns the remaining 50% working interest.
