Abstract

NMR-spinnekkosignaler samles inn nede i hullet. En partiell minste kvadraters metode brukes til å bestemme parametere for en parametrisk modell av den T2-fordeling som har utgang som stemmer overens med målingene. Modellparametrene telemetreres til overflaten, hvor egenskapene til formasjonen rekonstrueres.
