Abstract
A fracturing method comprises: pumping a first stream of liquefied petroleum gas and gelling agent with a first frac pressure pump; pumping a second stream of lubricated proppant with a second frac pressure pump; combining the first stream and the second stream within a wellhead into a combined stream; pumping the combined stream into a hydrocarbon reservoir; and subjecting the combined stream in the hydrocarbon reservoir to fracturing pressures. A fracturing apparatus comprises: a first frac pressure pump connected to a first port of a wellhead; a second frac pressure pump connected to a second port of the wellhead; a frac fluid source connected to simply a stream of frac fluid comprising liquefied petroleum gas to the first frac pressure pump; a gel source connected to supply a gelling agent into the frac fluid; and a proppant supply source connected to supply lubricated proppant to the second frac pressure pump.
