Reservoir Pattern Surveillance of Mature Floods Using Streamlines

Managing mature conventional floods--water polymer CO2 chemical or otherwise--hinges on properly describing well patterns. This book is about demonstrating that there is no better way to do this then using streamlines. Using streamlines for surveillance purposes is an option to keep mature floods operating efficiently and profitably when high-end simulation options are unavailable too expensive to deploy or simply overkill. The starting point for any improvement of an ongoing flood is the proper identification of well patterns and reliable pattern metrics. Where to inject more where less? How much fluid is being lost out-of-zone to the far field or aquifer. Which patterns have historically outperformed and which have underperformed? How much oil is recovered from each pattern for each unit of volume injected into the pattern? Answering these questions with confidence allows setting target rates that improve sweep and reduce fluid cycling.
