Abstract: Formation testing which may involve circulating mud in a pipe string from a mud pit through a port in the pipe string to a downhole diverter sub, wherein the pipe string is suspended in a wellbore extending into a subterranean formation, operating a downhole pump to pump formation fluid from the formation, wherein the formation fluid comprises gas, and mixing the pumped formation fluid with circulated mud such that a proportion of the pumped formation gas in the circulated mud is maintained below a threshold value.

Abstract: Collecting temperature data at a plurality of locations along a wellbore, performing thermo-mechanical simulations of a drill string in response to mud circulation wherein the drill string comprises a tool string suspended in the wellbore from a pipe string, determining changes in length of the pipe string due to temperature changes, positionally fixing the tool string at one of the locations, and adjusting the length of the pipe string based on the determined change in length of the pipe string. Positionally fixing the tool string may comprise lowering the drill string a side entry sub of the drill string is proximate a top end of the wellbore wherein the side entry sub is configured to allow a wireline cable to enter a bore of the drill string, positioning the side entry sub above a blow-out-preventer, and closing the blow-out-preventer around the drill string below the side entry sub.

Abstract: Flowline pressure equalizer systems, methods and/or apparatuses for use on a downhole tool are provided. A pressure equalizer may be provided in communication with two flowlines. The pressure equalizer may use equalizing chambers and equalizing pistons to regulate pressure in one or both flowlines. Further, one or more flow routing modules may be interchangeable to further alter the flow scheme between the flowlines. Different plugs may house various flow routing configurations such that the plugs may be installed and/or removed in the tool string automatically or by a user.
Abstract translation: 提供了用于井下工具的流线压力均衡器系统，方法和/或装置。 可以提供与两条流线连通的压力均衡器。 压力均衡器可以使用均衡室并均衡活塞以调节一条或两条流线中的压力。 此外，一个或多个流动路径模块可以是可互换的，以进一步改变流线之间的流动方案。 不同的插头可以容纳各种流动路径配置，使得插头可以自动地或由用户在工具串中安装和/或移除。

Abstract: A method, according to one or more aspects of the present disclosure, for calibrating a pump assembly includes characterizing one or more pumps of the pump assembly to determine one or more performance characteristics of the one or more pumps. The method may also include calibrating a sensor associated with a displacement unit of the pump assembly. Calibrating the sensor may include calibrating the sensor under operating conditions of a first environment and under operating conditions of a second environment. Under the operating conditions of the second environment, the one or more pumps can also be to determine one or more performance characteristics of the one or more pumps at the operating conditions of the second environment.
Abstract translation: 根据本公开的一个或多个方面，用于校准泵组件的方法包括表征泵组件的一个或多个泵以确定一个或多个泵的一个或多个性能特征。 该方法还可以包括校准与泵组件的位移单元相关联的传感器。 校准传感器可以包括在第一环境的操作条件下和在第二环境的操作条件下校准传感器。 在第二环境的操作条件下，一个或多个泵还可以在第二环境的操作条件下确定一个或多个泵的一个或多个性能特征。

Abstract: A tool is to be used within a wellbore including a wall and extending into a formation with formation fluid. The tool includes a packer expandable against the wellbore wall with ports included within the packer to enable formation fluid to flow into the tool from the formation. The ports are arranged in a first port configuration optimized based upon a first predetermined formation property.
