    Barito Basin The basin is subdivided into a structurally complex northern section,

    dominated by reverse-faulted anticlines, and a southern area characterized

    by undisturbed sediments.

    The northern part of the basin contains all the fields discovered to date,

    including the large Tanjung oil field (725 MMBO in place).

    Proven reservoirs include syn-rift alluvial facies middle-EoceneTanjung

    sands, fluvio-deltaic middle-late Miocene Warukin sands, pre-Tertiaryfractured basement, Oligo-Miocene fractured Berai carbonates.

    The basin has generated significant volume of hydrocarbons, however the

    existing accumulations do not show this big HC volume, leading to a Barito

    Dilemma (Mason et al., 1993; Satyana, 1995). Further exploration requires new ideas to acquire remaining hydrocarbon

    potential.

    Kutei and Makassar Strait Basins (1)

    The Kutei basin is arguably the deepest basin in Indonesia, the

    Tertiary column alone attaining a maximum thickness of about 14 km

    (Allen and Chambers, 1989), and it is 9 km deep in the productive area

    near Samarinda and the Mahakam delta.

    Basement is interpreted (Guritno and Chambers, 1999) to comprise

    Jurassic to Cretaceous oceanic crust and is covered by a thick

    turbidite sequence. The origin of Kutei basin was closely related with rifting in the

    Makassar Strait. Basin development throughout the Neogene was

    dominated by isostatic sag as a result of sediment loading.

    Stratigraphic nomenclature is confusing with a large number ofoperators having developed their own lithostratigraphic schemes.

    Kutei and Makassar Strait Basins (2) The major Neogene deltaic petroleum system has generated over 11

    BBOE in proven reserves. The thick pile of Neogene deltaics provide

    source rocks (delta-top and delta-front coals and shallow marine coaly

    shales) which are both oil and gas-prone, carrier beds (channel

    sands), and Miocene-Pliocene reservoirs of Balikpapan, Kampung

    Baru, and Mahakam formations that include channel and mouth-bar

    sands, and delta-front turbidites.

    All the major oil and gas fields in the Samarinda area are located onSSW-NNE trending, faulted anticlines of the Samarinda anticlinorium.

    Sources for deepwater oil fields like West Seno and Merah Besar are

    deep-marine, lowstand, coaly shales which range in age from early to

    late Miocene (Peters et al., 1999) The latest successes have been in the Makassar Strait area where

    Miocene, lowstand, turbidite fans of slope and basin floor fan deposits

    host significant oil and gas discoveries (like Ranggas, Sadewa,

    Gendalo)Awang H. Satyana (2005)

    Kutei and Makassar Strait Basins (3) Other under-explored potential include :

    large, pro-delta carbonate buildups

    smaller, shelfal, delta-front carbonates (Siemers et al., 1993)

    onshore syn-rift clastics (Guritno and Chambers, 1999)

    Oligocene carbonates toward the basin margin (Kerendan type)

    Tarakan Basin (1) The Tarakan basin represents a passive deltaic margin where the

    Sesayap and other rivers transport fine-grained sediments into the

    northern Makassar Strait. The basin is dominated by a series of NW-SE trending, sinistral

    transform faults and similarly trending anticlines, dividing the basin

    into four sub-basins : Tidung, Tarakan, berau,Muara sub-basins.

    In the offshore region, major north-south growth faults are thedominant structural control on sedimentation (Netherwood and Wight,

    1993).

    The distal, offshore stratigraphy is dominated by abundant deltaic

    clastics, and laterally equivalent, shallow- to deep-marine basinal

    shales and local carbonates.

    Landward paralic intervals contain coals and carbonaceous shales

    which represent a similar HC sources to those of the Mahakam delta.

    Tarakan Basin (2) The whole Miocene has rarely been penetrated. Older

    sediments are encountered to the western and southern parts

    of the basin.

    The is still potential for structural and stratigraphic traps along

    the large Bunyu and Tarakan arches. Some of the best

    opportunities are basinward of large growth faults, on rolloveranticlines where multiple-stacked sands occur. Opportunities

    also be possible in the lowstand fans that spill of the fronts of

    growth faults, such as very recently discovered Aster structure

    (Eni, 2005). Other opportunities include possible sourcing from

    deeper syn-rift sediments and possible large carbonate

    reservoirs in the south of the basin.
