Title:
METHOD FOR MEASURING DENSITY CHANGE OF UNDERGROUND MATERIAL USING GRAVIMETER
Document Type and Number:
WIPO Patent Application WO/2015/152521
Kind Code:
A1
Abstract:
Disclosed is a method for measuring density change of an underground material. In order to measure density change of an underground material, a borehole is formed on the top portion of the underground material which is subjected to measurement; and a first gravimeter and a second gravimeter are respectively installed on the outside and inside of the formed borehole. Subsequently, density change of the material which is subjected to measurement is calculated on the basis of a first gravity change and a second gravity change measured using the first gravimeter and the second gravimeter. According to the method for measuring density change of an underground material, it is possible to accurately measure density change of an underground material which is subjected to measurement, such as oil, gas, etc. stored in an underground reservoir, and carbon dioxide, injected into underground storage.
