    • Systems, methods and devices for evaluating a condition of a downhole component of a drillstring. Methods include estimating a value of a tool parameter of the component at at least one selected position on the drillstring; and using the estimated value to evaluate the condition of the downhole component. The estimating is done using a trained artificial neural network that receives information from at least one sensor that is positionally offset from the selected position. The method may further include creating a record representing information from estimated values of the tool parameter at the at least one selected position over time. The at least one selected position may include a plurality of positions, such as positions at intervals along the component, including substantially continuously along the component.
    • 用于评估钻柱井下部件状况的系统,方法和设备。 方法包括在钻柱上的至少一个选定位置处估算部件的工具参数的值; 并使用估计值来评估井下部件的状况。 估计是使用训练的人工神经网络完成的,该网络从位置偏离选定位置的至少一个传感器接收信息。 该方法可以进一步包括随时间创建表示来自至少一个选定位置处的工具参数的估计值的信息的记录。 该至少一个选定位置可以包括多个位置,诸如沿着该部件间隔的位置,包括沿该部件基本上连续的位置。

    • A method of processing data generated from an energy industry or oilfield operation includes: receiving a data set representing parameter values generated during at least a portion of the operation, the parameter values including values of a plurality of parameters relating to the operation; dividing the data set into a plurality of data subsets, each data subset including values for multiple parameters; determining a measure of similarity between data in each subset relative to data in one or more other subsets; displaying a map of the data set in at least two dimensions, the map including a visual representation of each subset positioned relative to a visual representation of the one or more other subsets based on the measure of similarity; and analyzing the map to estimate a condition associated with the operation.
    • 一种处理从能源工业或油田作业产生的数据的方法包括:接收表示在至少一部分操作期间产生的参数值的数据集,所述参数值包括与所述操作相关的多个参数的值; 将数据集划分成多个数据子集,每个数据子集包括多个参数的值; 确定每个子集中的数据与一个或多个其他子集中的数据之间的相似度的度量; 在至少两维中显示所述数据集的映射,所述映射包括相对于所述一个或多个其他子集的视觉表示定位的每个子集的视觉表示; 并分析地图以估计与该操作相关联的状况。

    • A system and a method for communicating data between a downhole tool and a surface controller is provided that comprises a rotating drill string (20) extending a borehole (26) and having a downhole telemetry module (72) disposed proximate a bottom end thereof and transmitting a first signal across a telemetry channel. A surface telemetry module is disposed proximate a top end of the rotating drill string and is adapted to receive the first signal transmitted by the downhole telemetry module across the transmission channel. The surface telemetry module has a radio frequency transmitter disposed therein for transmitting a second signal related to the first signal. A stationary communication module has a radio frequency receiver adapted to receive the second signal.
