A detailed geometry of sandstone reservoirs in slope turbidite channel – levee complexes is described.This architecture can be used as a good model in subsurface in the turbidites of Kutei basin hydrocarbon fields and/or other areas in Indonesia.Precise measurements of different architectural elements of the complexes are carried out in field outcrops. Sedimentary structures and architectural elements have been interpreted in a bigger stratigraphic scale.Recently open outcrops in the lower Kutei basin have been interpreted as slope turbidites. Some of these outcrops have been previously described as slope turbidites. The new outcrops show channellevee complexes. The sandstone bodies are mostly constituted by mass flows and debris flows which pinch out in short distance to thin bedded turbidites and silt shale alternations. This is interpreted as the lateral transition from proximal to distal levees. Channels are filled in general by thick mass flow deposits.The channel-levee complexes in slope turbidites are described in outcrops in the lower Kutei basin. They show the relationship between turbidite stratigraphy and the occurrence of channel-levee complexes. Sedimentary structures described give a good understanding of slope geometry, turbidite current load, shelf geometry and the nature of sediment input. The channel-levee complexes observed can be very good models for subsurface turbidite settings.Keyword: Lower Kutei basin, Samarinda, Lower to Middle Miocene, slope turbidites, channel – levee complexes, reservoir geometry, reservoir model
