Abstract: The method allows employing proppant surface modification with the emulsified treatment material for proppant delivery deep into far-field fracture zone during operations of hydraulic fracturing or heterogeneous proppant placement via proppant aggregation. In the case of gravel packing operations, to maintain the circulation of the proppant slurry for homogeneous proppant settling to the desired wellbore location. The emulsified treatment material can be degradable of non-degradable in downhole conditions.

Abstract: A method is given for fracturing a formation, in particular far-field in a tight formation, in which at least a portion of the proppant is crushable in situ at some point during pumping, during fracture closure, or at higher stresses experienced later during fracture closure. The closure stress or hydrostatic stress is estimated, then a proppant is selected that is at least partially crushable at that closure stress, and then the fracturing treatment is performed with at least a portion of the total proppant being the selected crushable proppant.

Abstract: A method includes identifying one or more stress regime types along at least a portion of a borehole, where the stress regime types are selected from a normal stress regime, a thrust stress regime and a strike-slip stress regime, and selecting reservoir access locations along the borehole based on the type of stress regime identified along the borehole.

Abstract: A method of treating a subterranean formation includes providing a plurality of cased wellbores penetrating a subterranean formation, where the plurality of cased wellbores is fluidly connected with a common treatment fluid source. Flow-through passages are then formed at a first zone within each wellbore of the plurality of cased wellbores, and the subterranean formation is treated by pumping a treatment fluid through the flow-through passages formed in the plurality of cased wellbores at a pressure sufficient to treat the subterranean formation. In some cases, the flow-through passages are a cluster of perforations. A fluid pressurizing system may be disposed between each of the wellbores and the common treatment fluid source.
