A method for MWD and/or LWD (100) wherein a plurality of pressures are measured at a plurality of locations along the drill string (155) to include the drill pipe with at least one pressure measured along the drill pipe wherein at least one downhole parameter condition (175) is detected based on at the least one measured pressure (150) with steps for using the computer and the computer programs and the computational systems (180) for detecting at the least one downhole condition.
L'invention concerne des procédés, des programmes informatiques et des systèmes permettant de détecter au moins un état de fond de trou. Les pressions sont mesurées en une pluralité de points, le long du train de forage. Le train de forage comprend une tige de forage. Au moins une des pressions est mesurée le long de la tige de forage. Au moins un état de fond de trou est détecté en fonction, au moins partiellement, d'au moins une pression mesurée.
