Title:
SYSTEMS AND METHODS USING TANDEM GRAVIMETER
Document Type and Number:
WIPO Patent Application WO/2013/096391
Kind Code:
A3
Abstract:
Systems and methods are provided for determining a property, e.g., density, of a geological formation based on Einstein's theory of gravitation. A tandem-structured gravimeter uses two gamma radiations emitted to two directions to determine a gravitational potential difference between two positions of the geological formation. The gravimeter can be a part of a downhole tool. The gravitational potential difference determined can be used to determine the property of the geological formation.
