Abstract

Spinn-ekko-signaler blir innhentet nedihulls med NMR. Prinsipalkomponentanalyse anvendes for å representere signalene ved en vektet kombinasjon av prinsipalkomponentene, og disse vektene blir telemetrert til overflaten. Ved overflaten blir NMR-spinn-ekko-signalene gjenopprettet og invertert for å bestemme formasjonsegenskaper. 1Spin echo signals are obtained downhole by NMR. Principal component analysis is used to represent the signals by a weighted combination of the principal components, and these weights are telemetry to the surface. At the surface, the NMR spin echo signals are restored and inverted to determine formation properties. 1
