During drilling, numerous gas shows were recorded over 220m of the Lower Silurian, Ordovician and Cambrian shales and a further 450m of gas shows were recorded in the middle and upper Silurian shale.
The strongest gas shows were encountered in the Ordovician shale, and the gas shows consisted of mainly methane, with a small percentage of ethane and propane.
The Ordovician shale interval in the Wytowno #1 well is approximately 83m thick and represents a thicker section than seen in previous wells drilled in updip, structurally higher positions.
This suggests an increasing thickness trend that may continue into deeper portions of the basin, the company said.
