Paper Number: SPE-195233-MS
... to 11. This reduction in total loads was achieved through the integration of components to their respective trailer systems, rather than assembling the components piecemeal. To facilitate the transport of loads without exceeding legal load dimensions, system trailers employ integrated hinge systems...

... substantial changes in hydraulic fracture conductivity and also in the nano-Darcy rock permeability in the near wellbore region. The reduction of nano-Darcy permeability is a function of pressure, time and distance from the hydraulic fractures. According to our results, the best reservoir management practice...

.... Anionic polymers are sensitive to polyvalent ions like calcium and iron, which can be found in hard groundwater, produced water, and flowback water. These ions can electrostatically crosslink the polymers, reducing friction reduction performance or even precipitating the polymers and potentially causing...
