    • Automated monitoring and management of well tests of hydrocarbon wells in a production field. Routing of the output of a well to a flow meter, separated from the output from other wells in the field is detected by a computer system such as a server. Measurement data including the flow as measured by the flow meter, and also other measurements such as temperatures and pressures contemporaneous with the flow meter measurements, are acquired by the computer system; a stable period is identified, over which the flow test measurement data are considered valid. Upon completion of a specified duration or upon a change in the flow environment, the computer system notifies the user of the completion of the flow test. The flow test results can be used to modify predictive well models, with the modification dependent on validation by the user. The system can also plan and schedule future flow tests.

    • A method and system for estimating reservoir pressure in a hydrocarbon reservoir from downhole pressure measurements of producing wells is disclosed. Pressure measurements are obtained from wells in the production field over time, and communicated to a server that applies the pressure measurements for a well to a model of that well. The server operates the model using the pressure measurements to determine an operating mode of the well. Upon detection of a change in operating mode indicative of an abrupt change in flow at the well, such as corresponding to a shut-in event, additional downhole pressure measurement data is acquired until a steady-state condition is reached. The pressure measurements are used to determine a reservoir pressure, which is transmitted to a responsible reservoir engineer or other user. Modification of the determined reservoir pressure value by the user can be received, and the stored reservoir pressure and well model are updated accordingly.
    • 公开了一种用于从生产井的井下压力测量值估计烃储层中的储层压力的方法和系统。 压力测量是从生产领域的井中随时间获得的,并传达给将井的压力测量值应用于井的模型的服务器。 服务器使用压力测量来操作模型,以确定井的操作模式。 在检测到表示井的流量突然变化的操作模式的变化(例如对应于关闭事件)时,获取额外的井下压力测量数据,直到达到稳态条件。 压力测量用于确定储层压力,其被传送到负责的储层工程师或其他用户。 可以接收用户对所确定的储层压力值的修改,并相应地更新存储的储层压力和井模型。
