Union Jack Oil plc announced initial results of the modelled flow rate analysis by RPS Group ("RPS") and the fluid analysis carried out on fluids produced to surface during the West Newton Extended Well Test ("EWT") programme carried out in H2 2021. Independent study by RPS Group indicates initial average potential production rates of up to 35.6 million cubic feet of gas per day ("mmcfd") (5,900 barrels of oil equivalent per day "boepd") from a horizontally drilled well situated in the gas zone, based on the data from West Newton A-2 well. Study also indicates initial average potential production rates of 1,000 barrels of oil per day ("bopd") from a horizontally drilled well situated in the oil zone based on data from West Newton A-2 well.

Fluid analysis confirms that hydrocarbon liquids recovered to surface are low specific gravity, low viscosity, light oil or condensate with an API ranging from 45.9 to 49 degrees, and that gas recovered to surface is good quality with high heat content.
