Sample Background of the Study Impact of Injection Well Fractures on Well Injectivity and Reservoir Sweep in Water Flooding and Enhanced Oil Recovery
Impact of Injection Well Fractures on Well Injectivity and Reservoir Sweep in Water Flooding and Enhanced Oil Recovery Study Background Most water injection wells in waterflooded reservoirs have fractures that increase as the time passes. These fractures can have a considerable effect on the reservoir performance. Moreover, a single well model that predicts the length of injection well fractures by modeling fracture growth due to fracture face plugging and thermal stresses is coupled with a reservoir simulator to simulate injection wells that have fractures that dynamically grow with time (Neretnieks, 2007). The relative importance of the injected water quality, formation permeability, injection rate and the temperature of injected water on the rate of fracture growth are demonstrated. The single well model accurately accounts for all the physics of fracture growth at the injector while the reservoir sim...
