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.

Hybrid LPG frac

A vapor hood for a proppant blending system, with a proppant entrance port to receive proppant, the proppant entrance port having a one way valve to allow the flow of proppant but prevent the backflow of vapor when the proppant is not entering the vapor hood.

Proppant blender

An apparatus and related method for fracturing a formation penetrated by a well comprises a frac pressure pump, a frac fluid source, and a proppant supply source. The frac pressure pump is connected to the well. The frac fluid source is connected to supply a stream of frac fluid to the frac pressure pump. The proppant supply source has a proppant receiver, a positive displacement pump, and at least an inlet into the proppant supply source. The at least an inlet is connected to one or more liquid hydrocarbon sources to supply liquid hydrocarbons to proppant in the proppant supply source. The positive displacement pump is connected to pump proppant into the stream of frac fluid before the frac pressure pump. Fluid lines connecting the frac pressure pump, the well, and the frac fluid source have isolation valves spaced so that the volume of fluid containable between any set of neighboring isolation valves is less than or equal to 500 L.
