Blue Star and its partners have much to look forward to after their Sammons 315310C well in the Serenity prospect fully intersected the target Upper Lyons sand.

Where it gets exciting for the joint venture is finding that the entire 83ft (25.3m) high-quality gas column is gas-filled with no water encountered during drilling or testing.

This is encouraging for Blue Star Helium (ASX:BNL) given that flow testing carried out during drilling had returned gas flow rates as high as 500,000 cubic feet per day with flowing pressures increasing as the well was drilled deeper.

Casing has now been set at 1,270 feet in the shale that separates the upper and lower Lyons sands, allowing the Upper Lyons to be preserved for future completion while allowing for the Lower Lyons to be tested in isolation for more accurate pressure, flow and compositional analysis.

Going forward the operator Vectra Oil & Gas will first 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.

More wells to come

Sammons 315310C is drilling on the first of four well locations in the Serenity Area of Mutual Interest, which contains the historical State #3053-36-4 well where wireline log interpretation by the company highlighted the presence of gas in both the upper and lower Lyons formation.

The three follow-up appraisal/development well locations have already been approved.
