To estimate a state of a natural resource in pipeline equipment during extraction in an oil field, provided is an apparatus including a data acquiring section that acquires measurement data, measured by a measurement device, indicating a state of a natural resource that is a fluid flowing through an extraction network for extracting the natural resource; a state estimating section that estimates the state of the natural resource at least at one location differing from a location where the measurement device is provided in a flow path of the extraction network, using the measurement data and a model of the extraction network; and a margin calculating section that calculates a margin until flow path blocking matter is generated in the extraction network, based on the estimated state of the natural resource.

Apparatus, method, and program for estimating a state of a natural resource to be extracted

A data collection device includes a data collector configured to collect data from a device that outputs data, a time stamp adder configured to add a time stamp to the data collected by the data collector, a data storage configured to store the data to which the time stamp is added by the time stamp adder, a timing generator configured to generate a timing at which the data stored in the data storage is transmitted to a data server communicably connected via a first network, a request information acquirer configured to acquire request information for requesting transmission of the data, the request information being transmitted from the data server, and a data transmitter configured to transmit the data stored in the data storage to the data server based on the timing generated by the timing generator and in accordance with the request information acquired by the request information acquirer.
