摘要： Provided embodiments relate to introducing a water-drainage-rate-enhancing agent into a subterranean formation to enhance gas production following a relative-permeability-modifier treatment to decrease undesired water production. An exemplary embodiment provides a method of treating a subterranean formation such that initiation of gas production is enhanced following the treatment, the method comprising: introducing a relative-permeability modifier into at least a portion of the subterranean formation such that the relative-permeability modifier reduces permeability of the portion to aqueous fluids; and introducing a water-drainage-rate-enhancing agent into at least a portion of the subterranean formation. Another exemplary embodiment provides a treatment fluid comprising a carrier fluid, a relative-permeability modifier, and a water-drainage-rate-enhancing agent.

摘要： Methods for the completion of subterranean well bores in a multilateral well system are provided. More particularly, methods are provided for the sealing of junctions between lateral well bores and a parent well bore. The sealants used in accordance with the methods provided generally comprise any sealing composition which can be placed within a subterranean formation, and injected a sufficient distance into a region of the formation surrounding a junction between a first well bore and a second well bore in fluid communication with the first well bore, so as to prevent the undesired entry of formation fluids into either well bore in the region surrounding the junction.

摘要： A proactive conformance method for a well includes selecting a well either in a completion phase or early in a production phase of the well and performing a conformance treatment on the well in the completion phase or early in the production phase. The conformance treatment preferably is performed before the well is completed (i.e., sometime during the completion phase between the well having been drilled and the well being placed in production), such as after running open hole logging or before setting casing. Another preferred aspect is the use of magnetic resonance imaging, such as using magnetic resonance imaging to analyze the well to determine where unwanted mobile fluid is in a reservoir intersected by the well. Such a well is completed in response to using the magnetic resonance imaging, including treating the well to confine at least part of the unwanted mobile fluid determined to be in the reservoir.
摘要翻译：井的主动一致性方法包括在完井阶段或在井的生产阶段早期选择井，并在完井阶段或生产阶段的早期对井进行一致性处理。一次性处理优选在井完成之前（即，在钻井和井被投入生产之间的完井阶段期间的某个时间）进行，例如在开孔测井之后或在安装壳体之前。另一个优选的方面是使用磁共振成像，例如使用磁共振成像来分析井，以确定在与井相交的储层中的不期望的移动流体的位置。响应于使用磁共振成像而完成这样的井，包括处理井以限制确定为在储层中的不需要的流动流体的至少一部分。
