The wells are operated by partner Baja Oil and Gas which reported an initial flow rate of 330 barrels of oil per day from the Stanley-1 well, while the Stanley-2 well flowed between 130 to 135 barrels oil equivalent per day.
"These initial flow rates are a demonstration of the excellent production from multiple stacked reservoirs at Stanley,” said John Barr, Mosman chairman.
“Mosman will soon receive cash flow from these wells as they can be produced using existing production facilities.
“Further low cost Stanley development wells will be considered in due course.”
Barr added: "Stanley wells add to the production from our existing projects at Welch, Arkoma, and Strawn.
"Mosman is also encouraged by the start of drilling of the Dukas exploration well by Santos Limited in the Northern Territory of Australia.”
