Abstract: The study is focused on the Northwestern part of
the Darling Basin, and deals with a Stratigraphic correlation
and lithofacies distribution. This study involves correlation of
the regional stratigraphy in the Darling Basin of western New
South Wales that results from deformation of the Devonian
sequences. The interpretation based on well logs and lihological
data. Integrating well and lithological data to correlate the
sequence stratigraphic units, using sequence stratigraphy
approach are the main goals of this study. Analyses of
lithostratigraphic units from well-logs and lithology data were
used to develop a stratigraphic correlation of the northwest
Darling Basin. The stratigraphic boundaries of the intervals
were defined at marked changes in well-log characteristics and
lithology information. Correlation of three wells in the
northwestern part of Darling Basin allowed correlation and
chronostratigraphic subdivision of Devonian sediments. The
lithofacies of three wells Bancannia North-1, Bancanna South-1
and Jupiter-1 have been identified from northwest to
southeast. The lithofacies dominated by sandstone and minor
shale sediments mostly in Lower to Middle Devonian age, red
sandstone, porous sandstone and shale lithofacies (red beds) of
Middle to Upper Devonian sediments. Three stratigraphic
units were identified based on well logs characteristics and
lithofacies namely A, B and C.
