... 2012 ). The well trajectory definition is one of the first and one of the most critical decisions taken in the life of an oil/gas well. Except drilling the wellbore, all other operations of an oil or gas well can be redone/improved to remediate any error or ineffectiveness. However, once the well...

... placement, since critical data - distance to boundary, geometry of the remote reservoir top and fluid changes in transition zones - were available in real time. In all wells the trajectory was maintained within the zone of interest by taking the proactive, real-time decisions while drilling. The integration...

This example shows the situation of transient cuttings transportation over whole trajectory of the well, considering a rate of penetration of 10 m/h and a fluid flow rate of 0,0221 m 3 /s (350 gpm), without cuttings, initially. The simulation shows the bed build...
