Real Time Stratigraphy (RTS) is a novel development of a widely used basin and field scale correlation algorithm (INPEFA) that detects stratigraphic discontinuities and trends by distinguishing these from orbitally forced climatic changes in stratigraphic data. This allows for the development of a high resolution correlation.

Well placement in heterogeneous carbonates where rock quality is defined by variations in rock and pore textures and not mineralogy can be challenging. This often relies on the use of multiple LWD tools or techniques that require the use of cuttings with significant delay in decision making and cost efficiency.
