Abstract
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.
