The study consisted of a comprehensive sucker rod/tubing wear assessment and a statistical production performance assessment of approximately 160 vertical, directional and slant heavy oil wells on primary production. The influence of well offset, local curvature variation and equipment type on well productivity and servicing costs were quantified to provide economic information for use by operators in improving the performance of existing wells and in optimizing the future design and completion of directional wells.

The evaluation clearly showed that wells drilled in compliance with the survey interval guidelines recommended by C-FER had substantially less curvature variation and experienced fewer wear-related and operational problems.
