WELL CONTROL for the Rig-Site Drilling Team
INTRODUCTION
INTRODUCTION
The objective of this manual is to provide a good understanding of the
fundamentals of Well Control that can be applied to most Well Control operations.
In all cases, minimising the kick volume and closing the well in is our first priority.
We have tried, as far as possible, to avoid using specialist terms and iconography.
This manual describes industry recognised standards and practices and basic Well
Control procedures. They differ from our advanced Well Control methods which
tend to be well, formation, or rig specific. The manual covers the guidelines found
in API 16E, API 53 and API 59 along with the International Well Control Forum
syllabus. It also covers the basic requirements for IADC WellCap Certification at
all levels.
All Well Control principles rely upon an understanding that good planning and
early recognition and close in, is the best form of Well Control. Not all kicks are
swabbed kicks, many wells are drilled into unknown formation. It is recognised
that equipment can fail despite all the correct procedures being followed. This is
why you will find the equipment section comprehensive and useful for general
trouble shooting ideas.
