Blue Star Helium Ltd (ASX:BNL, OTC:BSNLF) has welcomed progress on the Sammons 315310C well by joint venture partner and AMI operator, Vecta Oil and Gas Ltd on the Serenity prospect in Las Animas County, Colorado.
Vecta advised that the upper Lyons sand has now been fully penetrated between 1,155 feet and 1,238 feet, representing an 83-foot gas column of high-quality reservoir.
The company says the upper Lyons is completely gas-filled with no water encountered during drilling or testing.
Vecta conducted flow testing at various stages throughout the upper Lyons drilling with gas rates (as high as 500,000 cubic feet per day through a 1.25-inch orifice) and flowing pressure increasing since the tests announced on 31 August, as the well was drilled deeper.
Casing set to 1,270 feet
Vecta has now set the Sammons 315310C well’s casing to 1,270 feet in the shale that separates the upper and lower Lyons sands.
This allows the upper Lyons to be preserved for future completion while allowing the lower Lyons to be tested in isolation for more accurate pressure, flow and compositional analysis.
In the short-term, the two companies intend to drill 20 feet into the lower Lyons sand for initial flow testing of the well for pressure and rate analysis and to collect gas samples to determine composition.
The Sammons 315310C well is one of four approved helium wells located in the AMI agreed between Blue Star (50%, non-operated interest), Prospero Oil and Gas LLC (25%, non-operated interest) and Vecta Oil and Gas Ltd (25% operating interest).
