摘要： This disclosure presents systems to enable downhole bi-directional communications using a long length of fiber optic cable located within or partially within the internal diameter of a set of lower pipe segments and communicatively coupled to one or more upper pipe segments that utilize pipe cable attached to the outside diameter of each of the upper pipe segments. The long length of fiber optic cable and the one or more pipe cables from the upper pipe segments allow for communication coupling between downhole tools and surface equipment and surface computing systems. In some aspects, the pipe cable attached to the upper pipe segments can be protected from wear using clamps, collars, cages, and other protectors. In some aspects, an optical signal generator and modulator, e.g., a light source, can be located downhole proximate the downhole tools, uphole proximate one of the upper pipe segments, or proximate the surface equipment.

摘要： This disclosure provides a method of determining a pore throat size distribution of reservoir rock, comprising injecting a set of different-sized probe particles through a portion of reservoir rock and measuring retention volumes or times of each of the different-sized probe particles eluting from the portion of reservoir rock. This disclosure also provides a testing apparatus comprising a probe tube for receiving a set of different-sized probe particles in an elution fluid returning from a portion of reservoir rock and an analytical module connected to receive the elution fluid from the probe tube. The module includes a flow cell to receive the elution fluid from the probe tube, a radiation source positioned to direct a radiation beam though a window of the cell into the eluting fluid in the cell, and a sensor for detecting portions of the radiation beam that have interacted with the different-sized probe particles such that retention volumes or times each of the probe particles of one size class can be distinguished from all other size classes of the set.

摘要： The present disclosure relates to methods and systems for using elastocaloric materials in subterranean formations. A variety of downhole packages, for example, electronic packages and instrumentation packages, are utilized in subterranean formations during hydrocarbon exploration and production operations. Downhole packages are typically designed to operate below a maximum temperature. When a downhole package is placed in the subterranean formation, its temperature may increase as a result of the natural temperature of the subterranean formation in which it is being used. Additionally, many of these downhole packages used downhole generate heat during operation which may raise the temperature of the downhole package. Reaching or exceeding the maximum temperature of a downhole package may result in ineffective operation and/or complete destruction of the downhole package. As a result, the downhole package may need to be frequently replaced. Furthermore, additional steps may be needed to ensure the temperature in the subterranean formation does not exceed the design temperature of the downhole packages and/or to cool downhole packages prior to being introduced into the subterranean formation.
摘要翻译：本公开涉及用于在地下地层中使用弹性热材料的方法和系统。在油气勘探和生产作业期间，地下地层采用各种井下封装，例如电子封装和仪器套件。井下封装通常设计为在最高温度以下运行。当井下套件放置在地下地层中时，其温度可能由于其所使用的地下地层的自然温度而增加。另外，在井下使用的这些井下封装中的许多在运行期间会产生热量，这可能会提高井下封装的温度。达到或超过井下包装的最高温度可能导致无效操作和/或完全破坏井下包装。因此，井下套件可能需要经常更换。此外，可能需要额外的步骤以确保地下地层中的温度在引入地下地层之前不超过井下包装的设计温度和/或冷却井下包装。

摘要： Methods for determining a density of a fluid are provided. The method can include passing the fluid through a conduit, measuring a vibration of the conduit by distributed acoustic sensing via a fiber optic cable coupled to the conduit, and generating a vibrational signal indicative of the measured vibration. At least a portion of the vibration of the conduit can be produced by the fluid passing therethrough. The method can also include measuring a temperature of the conduit and generating a temperature signal indicative of the temperature. The method can further include calculating the density of the fluid passing through the conduit by using the vibrational signal and the temperature signal.

摘要： A subterranean formation can be monitored using motion data. For example, a series of time-lapsed images of a well site can be received by a processing device. Motion data can be extracted from the series of time-lapsed images. The motion data can correspond to a difference between images in the series of time-lapsed images. Changes to a surface of the well site can be determined based on the motion data. Features of a subterranean formation of the well site can be determined based on the changes to the surface.

摘要： Disclosed are telemetry systems and methods that employ a plurality of electromagnetic transceivers disposed outside a well casing string at a corresponding plurality of depths along the casing string. Each transceiver includes one or more toroidal inductors circumferentially surrounding the casing string and inductively coupled thereto to allow signal transmission between transceivers via currents induced in the casing. In some embodiments, signals are relayed via a chain of transceivers to facilitate indirect communication between a surface facility and other transceivers located too deep for direct communication to the surface.
