Abstract: In an implementation, guiding a service flow is described. Historical behavior data of one or more users who use a target service is obtained for the target service. The historical behavior data is analyzed to obtain one or more user features. One or more target users are selected from one or more users who do not use the target service based on the one or more user features. Each target user has at least one of the one or more user features. Service flow guiding information is sent to each target user. The service flow guiding information guides each target user to use the target service.

Abstract: A method for calibrating a pump assembly is disclosed. The method includes characterizing a pump of the pump assembly to determine a performance characteristics of the pump. 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 pump can also be calibrated to determine a performance characteristics of the pump at the operating conditions of the second environment. The calibrated pump assembly is then used to draw fluid from a subterranean formation or conduct a formation test.
