US Patent:

47927577, Dec 20, 1988

Filed:

Apr 6, 1987

Appl. No.:

7/035084

Inventors:

William B. Vail - Bothell WA
Paul B. Schwinberg - Seattle WA

Assignee:

ParaMagnetic Logging, Inc. - Woodinville CA

International Classification:

G01R 3320

US Classification:

324303

Abstract:

Nucleons which are chemically bound to oil and water in geological formations possess magnetic moments which align in the earth's magnetic field causing the natural nuclear paramagnetism of the formation. An A. C. magnetic field at the Larmor frequency is repetititively applied to the formation adjacent to a borehole resulting in a repetitive excitation-relaxation process of the nucleons present within an "excitation zone" which results in an amplitude modulation of the paramagnetism within this zone. This physical process results in an amplitude modulation of the earth's magnetic field in the vicinity of the excitation zone of the formation and is called the Paramagnetic Logging Effect (PLE). The PLE may be measured with logging tools in open holes and within cased well bores. The PLE measures the following quantities within a predetermined excitation zone of the formation: amount of oil, amount of water, total fluid volume, the viscosity of oil present, oil saturation and water saturation factors, estimations of the permeability, positions of vertical oil and water boundaries adjacent to the borehole, and the locations of lateral discontinuities of the oil bearing formation.

Abstract:

Methods and apparatus are described to detect, measure, and determine the presence of unknown Groundloop currents flowing through unidentified circuit pathways within the wiring system distributed within a portion of a fuselage of an airplane substantially made from fiber-reinforced composite materials to avoid catastrophic failures of the electrical system within such an airplane.
