EVALUATION OF DRILL BIT PERFORMANCE TAKING INTO ACCOUNT THE IN SITU STRESSES

EVALUATION OF DRILL BIT PERFORMANCE TAKING INTO ACCOUNT THE IN SITU STRESSES

PETRÓLEO BRASILEIRO S. A. === O presente estudo descreve uma correlação entre o desempenho obtido por brocas de perfuração e o estado de tensões atuante na formação rochosa localizada imediatamente abaixo do fundo do poço. Os dados de desempenho de brocas de seis poços perfurados na costa marí...
