Abstract

Teknikker for å detektere et brønnspark i et borehull (1) omfatter opptak av et sett målinger ved hjelp av et sonisk verktøy (22) i borehullet, bestemmelse av borehullets slamlangsomhet ut fra dette sett av målinger, samt å sammenligne slamlangsomheten med et valgt kriterium, hvor da bestemmelsen av slamlangsomheten omfatter bestemmelse av fluidmoduslangsomhet som en funksjon av frekvensen for minst én fluidmodus, og å bestemme slamlangsomheten ut ifra denne fluidmoduslangsomhet.
