摘要： A fluid-impermeable barrier, used to isolate stimulated intervals in a reservoir during a multi-zone fracturing operation, may be removed from the wellbore which penetrates the reservoir using a circulating fluid containing dissolvable solid particulates. The dissolvable solid particulates bridge perforation clusters during clean-out of the wellbore and thus inhibit passage of the circulating fluid into the fracture network through the perforation clusters.

摘要： A packer on a tubing string and diverting material pumped down the tubing string may be used isolate a fracture cluster in a multizone horizontal wellbore that has been previously hydraulically fractured. Once hydraulically isolated, fluid may be pumped down the tubing string to re-fracture the previously fractured fracture cluster in an effort to increase hydrocarbon production from the horizontal wellbore. The tubing string may include a testing device used to determine whether a specific fracture cluster within the horizontal wellbore should be re-fractured. Diverting material may be pumped down the tubing string and positioned adjacent a fracture cluster to hydraulically isolate the fracture cluster during the re-fracturing process. The diverting material may be cleaned out of the horizontal wellbore after all desired fracture clusters along the horizontal wellbore have been individually re-fractured.

摘要： A method of distributing proppant in a spatial arrangement throughout a created or enlarged fracture by pumping into a subterranean formation penetrated by a well multiple stages of fracturing fluid wherein a fluid laden with proppant is pumped into the well and a fluid substantially free of proppant is then pumped into the well; the fluid of the fluid laden with proppant and the fluid substantially free of proppant being the same. Vertically extending pillars are created within the formation. Fluid produced from the hydrocarbon-bearing reservoir is then flowed at least partially through channels between the vertically extending pillars.

摘要： 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 mixture comprising a dissolvable diverter and a proppant. At least a portion of the high permeability zone is propped open with the proppant of the mixture and at least a portion of the high permeability zone is blocked with the diverter. A fluid is then pumped into the subterranean formation and into a lower permeability zone of the formation farther from the wellbore. The diverter 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 mixture has particular applicability in the enhancement of production or hydrocarbons from high permeability zones in a fracture network located near the wellbore.
摘要翻译：井处理流体的流动可以通过使用包含可溶解分支器和支撑剂的混合物从高渗透性区域转移到地下地层内的断裂网络内的低渗透性区域。高渗透性区域的至少一部分用混合物的支撑剂支撑开，并且至少一部分高渗透性区域被分流器阻挡。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，高渗透性区域中的分流器可以在原位储层条件下溶解，并从断裂网络的高渗透性支撑区域产生的烃溶解。该混合物特别适用于在位于井筒附近的断裂网络中增强来自高渗透性区域的生产或烃。
