Abstract

En fremgangsmåte samt utstyr for å avverge eller nedsette til minimal påvirkning uønskede utborings-hendelser under en boreprosess er angitt. Boreriggens tilstand detekteres, fortrinnsvis automatisk, basert på måledata på overflaten og/eller nedihulls. Én eller flere uønskede utboringshendelser blir detektert ved å korrelere de opptatte måledata med den detekterte tilstand. Det fastlegges et boreriggtiltak som avverger eller nedsetter til minimal virkning en detektert uønsket utboringshendelse. Endelig blir utboringsprosessen overlagret av beordret utførelse av tiltaket. Den algoritme som brukes ved detektering av den mest sann-synlige boreriggtilstand er fortrinnsvis sannsynlighetsrettet i sin art, og er enda mer foretrukket basert på partikkelfiltreringsteknikker.
