Many people ask us every time about well control but many of them understand that well control is when the rigs are burn. This is not the right concept.
Well Control is a situation when hydrostatic pressure in a wellbore is less than formation pressure therefore reservoir fluid will come into a well. If a well control situation is not taking care of properly, it will result in blow like you can see in the VDO below.
The short VDO, only 1 minute and 34 seconds, clearly show that what will be happening if the well cannot be control.
This is another example of blow out.
