Resumen:
An appropriate propped fracture is important for oil and gas production (especially in shale formations). The actual proppant placement during fracturing is generally unknown. Any fair prediction of the placement of the proppant may results in significant improvements for the fracture protocol design. We present experimental data on the transport and settling of particles dragged by water through a narrow wedge-shaped vertical fracture. We discuss some basic features of the dynamics of the settlement of the proppant dune and show results on the final placement for different pumping rates and particle sizes. Results are consistent with previous findings by others and confirm that some usual practices in the field are beneficial to maximize the propped volume and minimize arching.
