METHOD FOR PREDICTING OF HYDRAULIC FRACTURING AND ...

A method of predicting hydraulic ,fracturing, and associated risks of hydraulic ,fracturing, operation is proposed. The methods use the mathematical simulation which allow to predict the geometry of a hydraulic fracture and location of fluids, propping agents (proppant), fibers and other materials therein. Reconsidering the ,fracturing, design allows to remedy the possible risks (overflash, screen ...

The ,fracturing, takes place at the start of the wellbore's life cycle. The injected ,fluid, is often water, and it usually contains various chemical additives and a proppant, like sand, to keep the fractures open so oil and gas can flow to the well. For more information on hydraulic ,fracturing, fluids, see FracFocus.ca.
