Abstract
Official abstract text for this publication.
Systems and methods are provided for determining a property, e.g., density, of a geological formation based on Einstein's theory of gravitation. A gravitational potential difference is determined between two positions of the geological formation by measuring a frequency shift of radiation travelling from a source to an absorber of a differential gravimeter. The differential 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system for determining a property of a geological formation, the system comprising: a component disposed about a downhole tool, the component to measure a frequency shift of gamma radiation travelling from a first position of the component to a second position of the component, the frequency shift resulted from a gravitational potential difference between the first position and the second position, which correspond to respective positions of the geol…
