Abstract: Most directional well drilling problems detected in Brazil, and also verbally reported by service companies abroad, occur during tripping operations. A comprehensive research program was undertaken to study this problem. The work is summarized in this paper, and shows the development of a field analysis procedure that proved to be reliable and thus translates into significant cost savings. The field data was obtained using an in house mud logging offshore unit and service companies' drilling sensors. The analysis was performed using the new developed method - Two Stage Type Curve Matching: an alert hook load expert system, followed by a pseudo fabrication factor `signature' analysis. Field results showed this to be useful for early borehole detection.
