Description and Geology

The Mereenie Oil and Gas Field was discovered in 1963 and commenced production in 1984. The hydrocarbon accumulation is contained in an elongate four-way dip anticline that has a length of 40 km and width of more than 5 km. Reservoirs comprise a series of interbedded sandstones of the Pacoota Formation which have been the development focus, as well as the overlying Stairway Sandstone which has produced gas in most wells while drilling and several wells have been completed as gas producers.

More than twenty separate conventional reservoir sands have been identified and correlated across the field, with typical individual net sand thicknesses of less than 5 m.  The Mereenie field has a gross hydrocarbon interval of more than 800 m with a gas cap and an oil rim.
