Abstract:As the petroleum industry builds long-term production histories in major liquid-rich unconventional resource (UCR) plays, development geologists and engineers have come to realize the production GOR, petroleum type, and ultimate recoveries do not always match the predictive petroleum system models. Early studies suggested the UCR petroleum systems neither require traditional petroleum traps nor major migration systems, but simply an organic-rich source within the optimal maturity window.
