A blender apparatus is disclosed having a chassis, a mixer positioned on the chassis, and a transfer pump positioned on the chassis. The mixer has a mixer housing defining a first mixer inlet, a second mixer inlet, and a mixer outlet. The first mixer inlet receives a liquid component, and the second mixer inlet receives a dry component. The mixer pressurizes at least the liquid component within the housing and discharges the liquid component through the mixer outlet at a first pressure above hydrostatic pressure. The transfer pump has a pump housing defining a pump inlet, a pump outlet and is devoid of an inlet configured to receive a dry component through a gravity feed. The transfer pump receives the liquid component through the pump inlet, pressurizes the liquid component within the pump housing, and discharges the liquid component through the pump outlet at a second pressure above hydrostatic pressure.
