Wellbore trajectory quality management is a key factor while deploying casing and completion strings. Depending on the type of directional drilling driving system, formation drilled, bit steerability and operational procedures, the trajectory can be smooth or very tortuous with significant additional local doglegs. In addition, when the wellbore surveying program is not sufficiently consistent (i.e. wellbore surveys with inadequate MWD survey sampling or Stationary Gyro surveying mode with a low sampling rate), the doglegs can be hidden and become potential difficulties down the track, resulting in ‘traps set open' for tubular running operations. This paper presents a trajectory quality management methodology that enables the anticipation of stuck pipe problems or lock up situations when running casing and/or completion strings. This methodology involves different processes that permit the evaluation of: intermediate doglegs and wellbore tortuosityprecise casing positioning through the wellbore accounting for centralisation programtubular post buckling analysis Robust 3D directional drilling models coupled with 3D stiff string T&D calculations (enhanced tubular string mechanics analysis) and adequate field data management are the key features of this successful approach.
