Abstract

Oppfinnelsen er en fremgangsmåte og anordning for bestemmelse av en elektrisk egenskap hos en formasjon som omgir et borehull med en måling- under-boring-innretning. Anordningen omfatter en anteimekonfigurasjon (1054) anordnet langs ytieflaten til stabilisator (1033) forbundet med et roterbart vektiør. Stabilisatoren kan være uttrekkbar eller utskyvbar. Typisk er to mottakere og to sendere anordnet med innbyrdes avstand langs vektiørets lengdeakse, med to mottakere innbyrdes atskilt symmetrisk mellom de to sendere. Altemativt kan mottakere og sendere være anordnet med innbyrdes avstand langs omkretsen, eventuelt over flere stabilisatorer. Et flertall av enheter kan brukes. Data kan innhentes med sender-mottaker-enheten holdt i stasjonær stilling eller omkretsmessig roterende. Anordningen kan arbeide i en "tverrstiåler"- konfigurasjon, en langstråler"-konfigurasjon, eller en konfigurasjon der sender spoler og mottakerspoler er orientert ortogonalt med hverandre.
