An important activity in characterizing natural reservoirs of petrochemicals is constructing models of rock physics, which represent how properties of rocks result in observable characteristics. This model-centric approach contrasts with an analysis-based approach, which reasons backwards from observables to rock properties. The process used in the model-centric approach consists of:
ConocoPhillips sought to develop a tool that would implement this model-centric approach, and also provide:
Enthought developed Converge, which provides a highly flexible visual programming environment for developing forward models for seismic petrophysical analysis. Expert users can define dataflows by connecting ‘chips’ that represent transformation functions.
These functions can be combined graphically to meet the needs of the modeling problem, without writing code. However, if a novel function is needed, the user can write a script for it and turn it into a chip to use the dataflows. In this case, writing of script code is limited to small, reusable modules, rather than entire models. Converge’s optimization feature provides inversion capability for tuning models.
ConocoPhillips scientists are able to create predictive models for natural reservoirs of petrochemicals rather than being limited to retrospective analyses of observable characteristics.
