Title: Hydraulic fracturing with a refractory proppant combined with salinity control

Patent ·
OSTI ID:5323000

This patent describes a method for controlling fines or sand in an unconsolidated or loosely consolidated formation, or reservoir which method additionally improves heat transfer. It comprises: placing at least one wellbore in the formation; hydraulically fracturing the formation via the wellbore via a fracturing fluid which creates at least one fracture; placing a fused refractory proppant consisting essentially of silicon carbide or silicon nitride into the fracture which proppant gravel packs the fracture while providing for increased heat transfer into the formation; determining the critical salinity rate and the critical fluid flow velocity of the formation or reservoir surrounding the wellbore; injecting a saline solution into the formation or reservoir at a velocity exceeding the critical fluid flow velocity and at a saline concentration sufficient to cause the fines or clay particles to be transferred and fixed deep within the formation or reservoir without plugging the formation, fracture or wellbore; and producing via a thermal oil recovery method a hydrocarbonaceous fluid from the formation or reservoir at a velocity such that the critical flow velocity is not exceeded deep within the formation, fracture or wellbore.
