METHODS AND SYSTEMS FOR PERMANENT GRAVITATIONAL FIELD SENSOR ARRAYS

摘要

A gravitational logging method includes obtaining gravitational field measurements from a permanent array of downhole or subsea sensor units. The method also includes inverting the gravitational field measurements as a function of position to determine a reservoir property. A related system includes a permanent array of downhole or subsea sensor units to obtain gravitational field measurements. The system also includes a processing unit that inverts the gravitational field measurements as a function of position to determine a reservoir property.
