Spudded on September 5, Landsowne-1 was drilled from a surface location about five kilometres south of the Agincourt Platform with a bottom hole objective location about 2.8 kilometres north-east of the surface location.
The Lansdowne structure lies in a similar geological setting to the previous successful oil discovery at Artreus-1, and good reservoir sandstones were intersected at the top of the Double Island and Flag Sandstones.
“The Lansdowne-1 well came in close to prognosis and the reasons for failure of the well to find hydrocarbons are uncertain at this time,” junior partner Tap Oil said.
The Ensco 67 drilling rig is now scheduled to move to the Kultarr prospect in permit WA-334-P. But if the weather forecast is unfavorable the rig will to move to the Kew prospect in the Harriet Joint Venture permit TL/9.
The Harriet partners are: Apache Northwest (operator and 68.5%), Kufpec Australia (19.3%) and Tap Oil (12.2%).
