摘要： Formation testing systems and methods may inject fluids into a formation to initiate fractures and facilitate measurements of various formation properties. In accordance with certain disclosed embodiments, the injection tools are further provided with nuclear magnetic resonance (NMR) sensors to monitor the injected fluids and provide measurements of near-borehole fracture orientations and volumes. Contrast agents and/or magnetic resonance imaging (MRI) techniques may be employed. The fluid injection may occur via an extendible isolation pad, via a fracturing jet, or via an injection port in an isolated region of the borehole. The systems may employ pressure monitoring in conjunction with the NMR sensors to further enhance estimates of formation and fracture properties.

摘要： Disclosed systems and methods provide well creation in a single trip. Some system embodiments include: a casing string having a distal end with a latch assembly; and a drillstring latched within the casing string by the latch assembly, the drillstring having at least one tool for perforation and stimulation. A pressure while drilling tool and one or more packers may be provided in the drillstring to further enable the stimulation operation. Prior to perforation, the casing string is cemented in place via a cement valve, and the drillstring is unlatched and raised to the desired completion position. The perforation and stimulation process can be repeated to provide multiple completions. The drillstring can be removed from the borehole or seated in place to control production. Logging instruments can be included for steering and/or use in making completion decisions.
摘要翻译：公开的系统和方法在单次旅行中提供良好的创造。一些系统实施例包括：具有具有闩锁组件的远端的套管柱; 以及通过闩锁组件锁定在套管柱内的钻柱，钻柱具有至少一个用于穿孔和刺激的工具。可以在钻柱中提供钻孔工具和一个或多个封隔器的压力，以进一步实现刺激操作。在穿孔之前，套管柱通过水泥阀胶合到位，并且钻柱被解锁并升高到期望的完成位置。穿孔和刺激过程可重复提供多次完成。钻柱可以从钻孔中移除或安置就位以控制生产。可以包括测井仪器用于转向和/或用于完成决策。

摘要： A disclosed downhole optical imaging tool includes a light source and a camera enclosed within a tool body having at least two sidewall windows. A first window transmits light from the light source to a target region in the borehole, while a second window passes reflected light from the target region to the internal camera. The target region is spaced along the borehole away from the second window in a direction opposite the first window. In some embodiments, this configuration is provided by angling the first and second windows with respect to the sidewall, or by shaping the windows to cast and receive light from a “forward” direction. Some tool embodiments include motion and/or orientation sensors that are employed by a processor to combine separately captured images into a panoramic borehole image. It can be employed during drilling operations employing air or a substantially transparent liquid as a drilling fluid.
