| Summary: | Latih Formation in Berau area mainly composed of sandstone, which in
Tarakan Sub-basin known as Meliat Formation, is believed as a proven reservoir.
In Berau area, which is still part of Berau Sub-basin of Tarakan Basin, Latih
Formation are found in Tanjung Redeb area. A comprehensive knowledge in
characteristic and sedimentology of Latih Formation is expected to also be
applied on Meliat Formation as well, thus leads to a more focused exploration
activity. In order to reach the aim, two traverse lines along the road of Tanjung
Redeb-Sangatta and Tanjung Redeb-Tepian have been measured and analyzed to
identify the lower part vertical succession, with total 190meters thick, of Latih
Formation. Laboratorium analysis includes petrographical (13 samples),
granulometry (6 samples) and paleontological analyses (3 samples). A dominant
composition of arenites with iron oxide of hematit as cement is identified from
sandstone samples under petrographical analysis. Based on granulometry
analysis, sandstone samples has average grain size of medium sand, poorly
sorted, sub-rounded morphology and very equant sphericity. Paleontological
analysis has mentioned that Latih Formation was deposited within mid-neritic to
transitional paleobathymetry during Middle Miocene (N8-N10). Typical of deltaic
depositional environment, with combination of wave and tidal influence, is mainly
identified on the lower part of Latih Formation. |
