Basin Modeling

We carry out regional 1D maturity modeling studies designed to develop a regional model for geological and thermal history that can make accurate predictions at untested locations, and to improve our understanding of the geological history. Difficult phenomena, such as thermal events and other changes in heat flow, and reconstruction of events during unconformities are of particular interest for this geologic analysis. We strongly believe that the geological learning that one acquires in the process of building and optimizing a set of 1D models is often the most valuable product of such a study, and we therefore emphasize careful and integrative model building. We use our proprietary Novva software for our 1D modeling.

The results of the 1D modeling can be used in a number of additional and more-traditional ways: to predict the precise level of hydrocarbon generation and cracking at each location; to help locate sweet spots in unconventional or hybrid plays; and to define the effective kitchen and migration pathways in conventional plays.

We carry out proprietary studies of this type routinely for clients in areas where they have a current commitment, or in areas under evaluation for possible investment. Studies normally include a mixture of calibration wells that aid in the geological reconstruction and learning, and pseudowells that allow us to predict maturity beyond or between well control. Pseudowells are often located in the deepest undrilled parts of a basin, or in deepwater offshore locations that are now becoming of interest.

We are able to use the data in 1D models created with Novva as the foundation for building 3D models to simulate migration. We work in collaboration with our StratoChem partners in providing 3D migration output using Trinity® software to model migration.

Ro values can be measured directly, or can be obtained by conversion of other thermal indicators, such as TAI, CAI, and Mean Ea.

The small highlighted area has been defined by a combination of the calculated TR values and the local economic criteria for successful unconventional exploration. These and similar maps can also be used to define effective kitchens for conventional and hybrid plays.
