Paper Number: SPE-165097-MS
... strong initial results is the use of dipole sonic logs to determine closure stress. From closure stress, formation breakdown pressures can be determined, which are used to design more effective treatments and place them more efficiently in the well and reservoir, where breakdown pressures are lower...

... to soften the formation by 23% and 58%. The post-immersion values predict that total embedment of proppant at maximum anticipated closure stress of 13,900 psi should not exceed 40% of the diameter of a grain of proppant. The results suggest that high-strength proppants should be used in sufficient...

... in addition to the length of conductive fracture. In order to have sufficient conductivity after fracture closure, the fracture face must be non-uniformly etched by the acid while the strength of the rock is still maintained at high levels to withstand the closure stress. A systematic experimental study...

...-temperature, high-flow rate wells. Additives included in the liquid resin system can eliminate fracturing fluid interference and permit good consolidation properties to be achieved without any formation closure stress. Results of this work demonstrate the difficulty in designing fracturing treatments...

... charge, wettability, and proppant tackiness, greatly influence fines migration into a proppant pack, regardless of the proppant sizing criteria used. API conductivity measurements performed with realistic pressures, closure stresses, and flow rates were used to confirm micromodel observations...
