Paper presented at the SPE Production and Operations Symposium, March 1–5, 2015
Paper Number: SPE-173633-MS
.... Also the effect of factors is studied, such as injection pressures, fracture spacing, and parallel well distances, on simul-frac results. With a lot of calculated graphs, the paper concludes that, for a homogeneous and isotropic rock, the two fractures form a simul-frac will propagate toward each other...

The elements of straddle packers have relatively modest anchoring requirements, because injection pressure is applied between the elements which causes...
