The formation and migration of thermogenic gasses and condensates in carrier reservoir systems

Objective

The overall goal of this project is to substantially improve our understanding of the factors governing, on the one hand, the origin, alteration and destruction of light hydrocarbons in petroleum reservoirs, and on the other the phase behaviour and flow characteristics of gas as a function of rock and fluid properties.

The outcome will be a quantitative geochemical inventory of precursors, products and rates of chemical change which can be directly applied to petroleum reservoir evaluation and the prediction of oil versus gas occurrence in geologically hostile drilling environments.


This project will determine the kinetics of oil to gas cracking for major primary crude oil types and distinguish the so-formed gases and condensates from those generated directly from source rock organic matter. Kinetic predictions will be tested using geologically well defined case histories. The influence of various polar compound types, water and pressure on the rate of crude oil cracking in reservoirs will be examined. Microscopic and macroscopic process descriptions of convective gas migration from deep geological structures will be developed, end-values of mobile/immobile phase saturations in carrier and reservoir systems monitored. Input functions and parameters for basin and reservoir migration modelling will be defined using petrophysical laboratory measurements.
