Patent

CA 2482457

A method, apparatus and system for predicting the formation pressure ahead of a bit in a well, which includes using measurements taken in shales and permeable formations at or near the bit together with centroid calculations to improve models predicting what the pressures ahead of the bit will be.

L'invention concerne un procédé, un dispositif et un système servant à prédire la pression de formation en avant du trépan dans un puits. Le procédé consiste à utiliser des mesures prises dans des formations schisteuses et perméables au niveau ou à proximité du trépan, conjointement avec des calculs du centroïde, pour améliorer des modèles prédictifs de la pression en avant du trépan.
