The advanced Chemistry Basin Model project has been operative for 18 months. A number of tasks are reported on. The first task is to Develop a database of additional and better maturity indicators for paleo-heat flow calibration. The second task is to Develop maturation models capable of predicting the chemical composition of hydrocarbons produced by a specific kerogen as a function of maturity, heating rate, etc.; assemble a compositional kinetic database of representative kerogens. The third task of the project is to Develop a 4 phase equation of state-flash model that can define the physical properties (viscosity, density, etc.) of the products of kerogen maturation, and phase transitions that occur along secondary migration pathways. The fourth task of the project is to Build a conventional basin model and incorporate new maturity indicators and data bases in a user-friendly way. The fifth task of the project is to Develop an algorithm which combines the volume change and viscosities of the compositional maturation model to predict the chemistry of the hydrocarbons that will be expelled from the kerogen to the secondary migration pathways. The sixth task of the project is to Develop an algorithm that predicts the flow of hydrocarbons along secondary migration pathways, accounts for mixing of miscible hydrocarbon components along the pathway, and calculates the phase fractionation that will occur as the hydrocarbons move upward down the geothermal and fluid pressure gradients in the basin. The seventh and final task for the project is to Integrate the above components into a functional model implemented on a PC or low cost workstation.
