31 questions and answer about drilling well control, collected from IWCF course.
Perforating Is probably the most important of all completion functions in cased holes. Adequate communication between the wellbore and all desired zones, as well as isolation between zones, is essential to evaluate and to optimize production and recovery from each zone. The objective of perforating a well is to establish communication between the wellbore and […]
