Abstract
En detektorenhet (66) og fremgangsmåter som innbefatter en magnetoresistiv sensor (70) innrettet for å detektere uregelmessigheter i veggen (21) til en foringsrørstreng (11) anordnet i et brønnhull (10) er beskrevet. Eksempler på uregelmessigheter innbefatter gap eller mellomrom mellom foringsrør som skyldes foringsrørskjøter, luftgap i foringsrørgjenger i forbindelse med glatte foringsrørskjøter, utvidet foringsrørtykkelse som for eksempel skyldes ytre foringsrørkrager, skadet foringsrør, perforeringer og enten diskontinuiteter eller deformasjoner i foringsrøret. Detektorenheten og fremgangsmåtene detekterer forstyrrelser i jordens magnetfelt forårsaket av uregelmessighetene. Detektorenheten genererer hovedsakelig intet magnetisk eller elektromagnetisk felt slik at andre brønnhullsinstrumenter ikke blir påvirket av dens nærvær.
