Abstract
The growth of injection hydrofractures in transient linear flow in a low permeability, soft rock is discussed. Seventeen waterflood injectors in section 12 of the Middle Bedridge diatomite, three steam injectors in section 29 of the South Belridge diatomite, as well as forty four injectors in the Lost Hills I waterflood have been analyzed. A simple mass balance of hydrofracture growth during fluid injection, attributed to Carter, is corrected, extended to the case of variable injection pressure, and presented in simplified form. The growth of fracture area at constant injection rate is expressed in terms of two field parameters, the early `injection slope' in linear transient flow, and the average injection rate.
