Well-control revision
Practical preparation for IWCF Level 3 and Level 4
The Well Control app helps drilling and wellsite personnel revise the technical subjects commonly developed during IWCF Level 3 and Level 4 preparation. Practice covers well-control fundamentals, pressure calculations, kick warning signs, shut-in response, influx analysis, volumes, capacities, MAASP, well-kill methods and subsea well control.
Questions reinforce calculations and principles, while the glossary explains terminology in operational context. Quick Fire supports rapid recall. Real Incidents and Operational Scenarios connect technical knowledge with decisions, consequences and lessons from well-control events.
Complements formal training. It does not replace it.
Well Control is an independent educational and revision aid. It does not provide certification and must not replace accredited training, company requirements, approved well programmes, operational procedures or professional judgement. Read the Educational Disclaimer.
Frequently asked questions
About Well Control.
Does the app provide IWCF certification?
No. It supports preparation and ongoing knowledge retention, but it is not an official IWCF product and does not replace accredited training or formal certification.
Who is the app intended for?
Drilling engineers, drilling supervisors, wellsite supervisors, operations personnel, workover supervisors, completions supervisors and others working toward or maintaining Level 3 or Level 4 knowledge.
What makes Quick Fire different?
Quick Fire uses a short countdown to strengthen rapid recognition and recall. It is intended as a focused knowledge exercise, not a simulation of authority to make live operational decisions.
What is included beyond question practice?
A 747-term glossary, guided glossary learning, terminology challenges, interactive reviews of 10 real incidents and 40 branching operational scenarios.
Which platforms are supported?
Well Control is being developed for iOS and Android.
