Proppant-laden fluid

Hydraulic properties, that is, friction-loss calculations of proppant-laden fluids or slurries, are very important not only in the design of any hydraulic fracturing treatment but also in real-time monitoring of fracturing treatments. Recent advances (27, 28) in real-time fracture analysis have necessitated an accurate knowledge of bottomhole treating pressure (BHTP). To estimate BHTP, an accurate prediction of friction pressures of fluids in the flow conduit is required. It is possible to obtain the BHTP from the surface pressure with the following equation ... 

Proppants Solid particles in a suspension that is injected into a petroleum reservoir to maintain open fractures that have been artificially induced. The proppant-filled fractures then remain permeable to the flow of fluids. The suspension used for this purpose is sometimes termed proppant-laden fluid. See also Chapter 11.
