SYSTEM AND METHOD OF DETERMINING AND OPTIMIZING WATERFLOOD PERFORMANCE |
摘要 |
A system and method of map based assessment of waterflood are provided. The method includes generating a water injection influence (WII) map by mapping one or more connectivity parameters derived from a capacitance resistance model; calculating a recovery factor (RF) and pore volumes injected (PVI) for each injector influence region in one or more influence regions defined from the connectivity parameters; determining a maximum of the recovery factor versus the pore volume injected using a curve fit extrapolation; determining a volume of injection water needed or a number of injectors needed based on recovery factor versus pore volumes injected; calculating a voidage replacement ratio (VRR) within each injector influence region; determining a target voidage replacement ratio by selecting an average voidage replacement ratio with a most recent interval of time; and determining a number of infill wells with drilling schedule to maintain the determined target voidage ratio. |
