HEAT
HEAT is a powerful 1D forward-modelling tool designed to predict heat-flow, geothermal, maturation, and horizon-temperature history at well or pseudo-well locations. By inputting a 1D stratigraphic section, users can quickly generate depth-scaled temperature profiles and source rock maturation predictions (vitrinite reflectance). These results can be calibrated against present-day down-hole temperature and maturation measurements for accurate geological insights.
Key Features
1D Whole-Lithosphere Thermal
Model
The following geological constraints are incorporated in Heat's calculations:
- Tectonic history, the thermal consequences of multiple rifts.
- Whole-lithosphere thermal perturbation through time, a consequence of the tectonic history.
- Crust & lithosphere thinning, can be considered as uniform with depth or depth-dependent.
- Burial history, defined by input stratigraphy and lithology, with compaction incorporated
- Lithologically-controlled thermal conductivities within the sediment fill
- Radiogenic heat input from both the crustal basement and the sediment fill
- The thermal consequences of igneous intrusion into the basement or sediment fill
Quantify Heat-flow
History
Heat-flow history for both the top-basement and top-sediment interfaces is
predicted, spanning the full time history of the input stratigraphy.
Vitrinite Reflectance &
Temperature Calibration
Predicted values of vitrinite reflectance and temperature
can be calibrated against down-hole measurements.
Maturation index (%VR) and temperature can be overlaid as a backdrop to the complete burial
history of the stratigraphic sequence.
Fast &
efficient
Input of stratigraphy is intuitive, simple and easily integrated with
parameters controlling tectonic and geological history. The calculation engine is optimised so
that models run in seconds, making iteration rapid and straightforward.
Easy to use
Designed to be used by all geoscientists who wish to investigate the thermal consequences of the
processes which generate extensional basins and continental margins.
