From Mountains to the Sea: Every Great Discovery Starts With a Journey
Introducing the Neftex® Source to Sink
‘Source to sink’ is the appreciation of the complete sedimentary system, from initial erosion of hinterland lithology, to drainage, and, eventually, to deposition. At the highest level, it requires knowledge of a wide range of controlling factors, such as tectonics, uplift, erosion, climate, and sea level fluctuations. However, at the fundamental level, the key questions that should always be asked include: ‘Where has this package of sediment come from?’ and ‘How did it get here?’
Answers to these sediment provenance questions are complex but powerful factors in determining the quality of hydrocarbon systems within a basin. To help explorationists assess these key considerations Halliburton has developed new Source to Sink maps, available within the Neftex Insights® portfolio. These enable geoscientists to obtain a rapid, first-pass assessment of the potential quality and extent of sediments being derived from eroded hinterland within each drainage basin, at discrete time intervals. Users can visualize paleo-drainage basins and paleo-river networks as well as calculate the maximum depositional limit for sediments. An assessment of the quality of the hinterland material available for erosion within each drainage basin can be made and used as a proxy for sediment quality (Figure 1).
