“…Proven and candidate Incised Valley Fill (IVF) of very thick amalgamated channel sandstones that may correspond with the LST sequence boundaries in the onshore fields. The G053B IVF(Butterworth et al, 2001), and the I4200 IVF in this study have been observed from seismic and wells.…”

“…Due to limited well penetration in the Middle Miocene deep-water play, the 2D seismic data is considered key important tool in this study. The usage of seismic data (Malecek et al, 1993;Butterworth et al, 2001;Saller et al, 2008;Yoga et al, 2009;Pratama-Laya et al, 2014) is very helpful to define termination features such as incision, clinoforms, and geomorphology of the shelf, slope, and basin floor (Figures 2 and 3).…”

“…The geometry of G053B IVF feature demonstrates 3 km wide and 45 m thick well developed amalgamated channel sandstones. This IVF system requires a fall in relative base sea level of more than 50 meters in providing a topographic low due to lowstand incision that associated with sedimentary bypass to the deep-water setting at this sequence boundary (Butterworth et al, 2001).…”

Massive exploration effort in the study area was conducted in 1996-2014 when deep-water drilling campaign found significant oil and gas discoveries but yet to optimally reach the middle Miocene deep-water sandstone reservoirs. Outcrops, well bores and 2D-seismic data had been incorporated in this study. Datum age from several taxon indicators have been utilized to correlate and unify various markers across the study area into four key biostratigraphy markers: M40, M45, M50, and M65. These four markers are at that point tied to the 2D seismic data in the act of the main horizons in conducting the seismic stratigraphy analysis over the study area not reached by wells. Identifying candidate of sub-regional sequence boundaries onshore and offshore that correspond with relative sea-level drops are the main result of this study. These results were integrated to generate the deep-water fan facies of the middle Miocene's gross depositional environment (GDE) maps, which generally show prograding succession easterly in the various shelf-breaks shifting laterally. The angle of slope and the horizontal length of the shelf-to-slope breaks significantly change from the Middle to Late Miocene until Recent time.Keywords: GDE, deep-water fan, Middle Miocene, Kutei, North Makassar.

“…The sandstone's litho facies is further subdivided into four classifications: 1) cross-bedded fluvial sandstones (FLU_SX and DC_SX), 2) massive distributary channels (DC_SM), 3) bioturbated distributary channels (DC_SB), 4) bioturbated with mud/clay drapped bars (DF_SC). These are illustrated in the Figure 6, as well as the detailed core-description, core photos, and welllog types (modified from Butterworth et al, 2001;Lambiase et al, 2017;Riadi et al, 2018).…”

As we may all be aware the oil and gas wellbores offshore Kutei and North Makassar have not optimally penetrated the objective strata, which is the Middle Miocene’s deep-water reservoirs. Therefore, evaluating the quality of these reservoirs with onshore dataset then comparing them with the proven Late Miocene’s deep-water producing reservoirs had been very fundamental. The study focuses on the assessment of QFL and sandstones litho-facies based on the rock samples from conventional-core and side-wall core, and well-logs data from forty wells onshore and offshore. These rock samples are bounded by the key biostratigraphy intervals of M40M33, M45M40, M50M45 (Middle Miocene), and M65M50, M66M65, M70M66, M80M70 (Late Miocene). Subdivisions of the reservoirs considered the sandstone litho facies, NTG ratio, sorting, and grain size, to come up with five groups in the Middle Miocene deltaic facies: FLU_SX, DC_SX, DC_SM, DC_SM, and DF_SC; and four groups in the Late Miocene deep-water facies: SSWS, MSWS, SSPS, and MSPS. Core-based porosity and permeability further explain the relationship between the reservoir quality with the sandstones’ composition and litho facies, and concluded that high-energy depositional system is mainly associated with the FLU_SX, DC_SX, SSWS and MSWS being the reservoir with best quality. Oppositely, the DF_SC, SSPS, and MSPS are classified the reservoir with worst to none quality. A cross plot between core-based porosity and maximum burial depth is able to postulate the relational trend of decreasing reservoir quality with deeper depth.

“…This also excludes the need to invoke multiple sealevel changes for the literally hundreds of other sharpbased channel sandstones encountered in the Badak Field. Only one sandstone to date, in the Sanga Sanga PSC, the G053B Sand in the Nilam Field (Butterworth et al, 2001), is a convincing example of an incised-valley fill.…”

The Sanga Sanga PSC in the Kutai Basin of East Kalimantan is host to several gas and oil fields with hydrocarbons principally reservoired in Miocene fluvio-deltaic channel sandstones. Limestones form only a subordinate lithology in this area and carbonate development is restricted both temporally and spatially. The thickest and most extensive limestones are in the uppermost G interval of the Badak Field where several discrete horizons of limestones are interbedded with shales, sandstones and coals. Limestones exhibit an overall thickening upwards trend although individual limestones often display strong lateral variations in thickness and are notably absent from some wells. These limestones do not form reservoirs whereas laterally adjacent sandstones display similar production characteristics to carbonate-free intervals immediately above and below. An extensive blanket of thick shale in the basal F interval overlies this limestone bearing succession.
