Petroleum Prospecting License 436

Kina was granted, on 13th December 2013, a 50% share and operatorship in PPL 436. Kina’s JV partner in PPL 436 is Cott Oil and Gas

Location and Infrastructure

PPL 436 covers an area of 13,362 km2 onshore and is located in the southern foreland of the Papuan Basin in Western Province. It sits to the south east of PPL 435 and is close to the south coast of PNG and has good access via the Fly River.


PPL 436 overlies a complete Papuan Basin sequence with reservoir targets in the Darai, Base Cretaceous, Toro, Imburu, Koi-lange and Magobu. The southern flank of the licence has been affected by the Coral Sea tectonics with large down to the south faults setting up large trapping potential for the aforementioned reservoirs.

A significant oil seep was discovered at Panakawa in 2005. The seep confirmed a steady flow of non-biodegraded oil at an approximate rate of 5 barrel of oil per day at surface. This seep confirms an active oil kitchen very close to or underlying eastern PPL 436.

Previous Exploration

Seismic exploration commenced in the 1970’s with Marathon’s seismic lines along the Fly and Aramia Rivers followed by Texaco’s Morehead and Weam, Marathons Fly River, Conoco’s Aramia, LL & E’s Mata and Daraia, GEDD’s, Gem and Gas , Philips’ Gogodala and Sasol’s Awapa seismic surveys.

In 2009 a large regional aerogravity and aeromagnetic survey was flown by Sasol. Aramia-1 is the only well located within the licence but good well ties are possible from Adiba-1 to in the north east and just outside the licence. Aramia-1 drilled in 1955 without the benefit of seismic interested oil shows and all primary reservoir targets of the Papuan Basin. Morehead 1 and Mata 1 to a thickening depocentre to the south of the Fly River Fault.

Proposed Exploration

Limited seismic data exists within the license area but seismic carried has from the north and west and well data to the east confirms a large basement high underlies the central northern part PPL 436. The presence of the Fly River Fault a large north westerly striking down to basin fault is confirmed by seismic, well and aeromagnetic data. The 2009 aerogravity data confirms a large basement high underlies the Oriomo, Alligator and Sturt leads. Air photo analysis and seismic data correlated from Adiba-1 also indicate a possible north easterly fault trend throwing down to the south. The intersection at the orthogonal fault trends establishes a series of large leads identified in PPL 436. The integrated aeromagnetic and aerogravity coverage over PPL 436 confirms the above architecture. Vintage seismic data is currently being reprocessed to evaluate the very large prospects at Dalbert, Alligator, Sturt and Oriomo.

A proprietary integrated aerogravity and aeromagnetic data set now provides full gravity and aeromagnetic coverage over PPLs 436. Preliminary interpretation suggests two major zones of structural interest: a zone of Triassic basement north of the Fly Fault and an uplifted area of Palaeozoic/Proterozoic basement in the south, separated by a deep sedimentary pile (the Morehead Graben). Areas of primary interest remain the Oriomo High, containing the Dalbert, Alligator, Sturt and Oriomo prospects in PPL 436.

The Oriomo High area of PPL 436 is prospective based on the preliminary interpretation of the aeromagnetic and aerogravity data. It is a focus for oil generated from the east, being up-dip and on the drainage path from the Panakawa oil seep. It has multiple Jurassic and Early Cretaceous reservoir targets all at depths of 1800m or shallower.

KPL is commencing a major reprocessing effort of the existing seismic data base over PPLs 435 and 436. The focus of the reprocessing will be to confirm stratigraphy and thickness of reservoir sequences at Aiambak, Lake Murray East, Dalbert, Alligator, Sturt and Oriomo.
