Standardization of Uncertainty Quantification of Sub-surface Geological Models through a Field's Life Cycle

摘要

Introduction In the E&P life cycle of any field, quantification of uncertainty and its management play an important role for proper development planning. A hydrocarbon bearing reservoir in a field is developed as a result of certain geological processes. Sub-surface geological models are an attempt to best characterize it based on available data and interpretation. In a field's-life-cycle, the amount of gathered data and the interpretation carried out to understand the reservoirs increase exponentially from "Green" to its becoming "Brown". Subsurface uncertainties reduce in this life cycle due to better understanding of the reservoir.
