    Abstract: The flow of well treatment fluids may be diverted from a high permeability zone to a low permeability zone within a fracture network within a subterranean formation by use of a divert system comprising dissolvable diverter particulates and proppant. At least a portion of the high permeability zone is propped open with the proppant of the divert system and at least a portion of the high permeability zone is blocked with the diverter particulates. A fluid is then pumped into the subterranean formation and into a lower permeability zone of the formation farther from the wellbore. The diverter particulates in the high permeability zones may then be dissolved at in-situ reservoir conditions and hydrocarbons produced from the high permeability propped zones of the fracture network. The divert system has particular applicability in the enhancement of production or hydrocarbons from high permeability zones in a fracture network located far field from the wellbore.

    Abstract translation: 井处理流体的流动可以通过使用包括可溶解的转向颗粒和支撑剂的转向系统从地下地层内的断裂网络中的高渗透性区域转移到低渗透性区域。 高渗透性区域的至少一部分用转向系统的支撑剂支撑开，并且高渗透性区域的至少一部分被转向颗粒物堵塞。 然后将流体泵送到地下地层并进入距离井筒更远的地层的较低渗透性区域。 然后可以将高渗透性区域中的转向颗粒溶解在原位储层条件下，并从断裂网络的高渗透性支撑区域产生的烃溶解。 转向系统特别适用于在距井身远场的裂缝网络中增强来自高渗透性区域的生产或碳氢化合物。

    Abstract: Relatively low strength and/or relatively low density, but ductile materials may be folded or crumpled and finely divided to give proppants for introduction into hydraulic fractures, where the folded or crumpled structure of the proppants gives relatively increased strength relative to the relatively low strength and/or relatively low density of the materials. Materials not previously considered suitable for proppants may be considered when structure or configured in this manner. Similarly to the case where crumpled paper within a cardboard box keeps it from collapsing, the folded or crumpled material spontaneously develops structural rigidity at relatively low volume fractions without a specific externally imposed design. The folded or crumpled proppants may also be used alone or together with conventional proppants for sand control in gravel packs or frac packs.

    Abstract translation: 相对较低的强度和/或相对较低的密度，但是延性材料可以折叠或折皱并细分，以提供用于引入水力裂缝的支撑剂，其中支撑剂的折叠或皱缩结构相对于相对低的强度给出相对增加的强度， /或相对低密度的材料。 当以这种方式结构或配置时，可以考虑以前不被认为适合于支撑剂的材料。 类似于纸板箱内的皱巴巴的纸不会塌陷的情况，折叠或折皱的材料在没有特定的外部设计的情况下以相对低的体积分数自发地发展结构刚度。 折叠或皱缩的支撑剂也可以单独使用或与常规支撑剂一起使用，用于砾石充填或压裂包装中的沙尘控制。
