Abstract
Det er vist et sanntidstelemetrisystem for bruk med et boresystem innbefattende en rotasjonsventil (28) som styrer tilførselen av borefluid eller -slam til et brønnverktøy. Systemet omfatter mottak av data som skal overføres, omkoding av dataene som en varighet, og styring av rotasjonsventilens (28) rotasjon, slik at rotasjonsventilen (28) roteres for nevnte varighet med en forutbestemt rotasjonshastighet for å bevirke dannelse av trykksvingninger eller -bølger i borefluidet eller -slammet.
