Drilling and completing wells quite often encounter unexpected events during routine operations. Troubles occur that many times are easy to resolve while other times are more difficult and can completely turn the plan upside-down. Adapting the course of action to still meet well objectives involves many factors and individuals, incorporating innovative techniques and new technologies without compromising safety or environmental implications. This paper will discuss four case histories, which are examples of how well completion programs were modified due to unexpected events in order to salvage the well’s production potential. Coordinated teamwork between drilling, production, reservoir, and geoscience personnel to establish a revised plan in a timely manner, responding to operation/reservoir complications, is the key to success. Some of these creative alternatives were derived based upon specific well characteristics and are uncommon in normal operations. However, by sharing these techniques, others may be able to benefit from GUPCO’s key learning’s and respond to complications in their own operations.
