ABSTRACT

The Akimengah Basin is situated at northern Merauke Ridge that separates it from the Arafura Basin to the south. The area comprises the Arafura Platform to the southwest and foreland belt complex to the north is included the basement high of southern flank of Irian Jaya Fold Belt, which comprises flat-laying Middle Jurassic to Cenozoic sediments on a block faulted basement of Paleozoic to Triassic sediments. The structure of Akimeugah Basin is represented by its tectonic provinces consisting of folded and faulted sediments platform. From south to north is Arafura Platform, Foreland Fold Belt, and Basement High on the southern flank of Central Range of Papua (Irian Jaya Fold Belt). Total thickness of sediments on Akimeugah Basin is
approximately 10,000 m comprising a platform sequence of Paleozoic and Mesozoic clastic sediments, which are overlain by Tertiary limestone and young Cenozoic clastic deposits. Primary traps on Akimeugah Basin are considerably divided into 3 main systems that are located in Arafura Platfom, Foreland and Basement High. Those systems include structural trap (anticline, drag fault, ramp anticline, fault anticline and tilted block),
stratigraphic traps (reefal buildup and pinch out) and combination (structural and stratigraphic traps).
This paper will discuss about the interpretation of structural setting and stratigraphic control on the Akimeugah Basin area and surrounding to hydrocarbon exploration concept. It comprises regional tectonic setting, stratigraphy and depositional setting, and hydrocarbon prospects on the basin.
