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。

摘要： Methods and devices are provided for treating multiple interval well bores. More particularly, an isolation assembly may be used to allow for zonal isolation to allow treatment of selected productive or previously producing intervals in multiple interval well bores. One example of a method for treating a multiple interval well bore includes the steps of: introducing an isolation assembly to a well bore, the isolation assembly comprising a liner, one or more sleeves and a plurality of swellable packers, wherein the sleeves and swellable packers are disposed about the liner; deploying a shifting tool inside the liner, where the sleeves are configured so as to provide open, closed and open to screen positions when actuated by the shifting tool. An open position allows for treatment of the well bore while an open to screen position allows for receiving fluid from the well bore. A closed position re-establishes zonal isolation.

摘要： The present invention is directed to a method for producing gas from a subterranean formation containing a coal seam. The method includes the steps of drilling a substantially vertical well bore into the subterranean formation, which intersects the coal seam and fracturing the coal seam using a hydrajetting tool to produce at least one pair of opposed bi-wing fractures substantially along a plane of maximum stress. One or more horizontal well bores may also be drilled into the coal seam along which the coal seam can be further fractured.

摘要： The present invention is directed to a method of increasing hydrocarbon production in an existing well in a hydrocarbon reservoir. The method includes the steps of forming a substantially horizontal transverse fractured wellbore that intersects the existing well and injecting a fluid remote from the existing well so as to form a fluid front that sweeps the hydrocarbons into the horizontal transverse fractured wellbore. Successive fractures can be sealed to control propagation of the fluid front and delay infiltration of the fluid into the production.
