ABSTRACT OF THE DISCLOSURE A method for heating recovered crude oil at the site of recovery thereof and injecting at least a portion of such heated crude oil back into the oil formation in order to reduce the viscosity of oil remaining in the oil formation, the invention facilitates recovery of the remaining oil and renders the oil more easily handled through pumping operations. Apparatus according to the invention particularly provides for solar heating of a working fluid circulating through a closed heat exchange coil disposed within a crude oil storage tank located in proximity to one or more operating wells and normally used for temporary storage of oil pumped from the wells. Heat energy carried by the working fluid in the closed coil is transferred to the crude oil within the storage tank, the heated crude oil being then pumped back into the oil formation to heat the remaining oil in the formation, the viscosity of the remaining oil being reduced to allow a greater total recovery of the oil in the formation.
