Since the beginning of the petroleum industry, stratigraphy has been essential to understand the sedimentary processes through a range of scales, from reservoirs and their depositional architecture to basin filling.

 

The Uniformitarian Principle - in other words, sedimentary processes observed in the present are similar to those processes in the past - can be applied to their understanding; in addition of being a highly predictive tool.

 

With only a few exceptions, almost all hydrocarbons are generated or trapped in sedimentary rocks.  Establishing their temporal and spatial relationship is essential to properly identify and quantify oil and gas accumulations.

 

The stratigraphic analysis includes a wide spectrum of time and spatial scales, ranging from the identification of sedimentological characteristics, facies and associated processes in outcrops, well log characterization, and the interpretation of bounding stratigraphic surfaces in a reservoir and interpretation of the elements of system tracts and depositional sequences up to the infill of a basin.

 

In this context, not only a correct stratigraphic description and interpretation is essential, but also to accurately assess the main variables that control the process through sedimentary flow simulations and S2S (source to sink) modeling, involving not only sedimentary deposits but also their source.

 

At each scale, identification and understanding of sedimentary processes allows predicting what might occur beyond the sampling point or time interval under analysis. Such predictability transforms stratigraphy, from grain scale to basin analysis, into a key tool both for analyzing new exploration ventures as well as development optimization.
