Processing of Wellbore Anti-collision Signal Based on Empirical Mode Decomposition

An investigation of electromagnetic anti-collision real-time measurement for drilling cluster wells

“…Vibration monitoring is a series of methods which prevents wellbore collisions, mainly divided into two categories: casing vibration monitoring, and Measurement While Drilling (MWD) vibration monitoring (Guan et al, 2010;Liu et al, 2012Liu et al, , 2013. The casing vibration monitoring method measures the vibration signal of the well casing head on the ground.…”
