RE: What about the gas?25 Sep 2023 12:10
Bubble point can be massive problem in Oil base muds. Oil is compressible in the mud. Water based muds are basically non compressible. Can not compress water.
In oil base muds the gas can hide till bubble point and then by Boyles Law expands rapidly. Usually around 1000 feet from surface and hits very fast on a land rig or Jack up. The BOP has to be shut in as soon as the kick is noticed. If not!!!!
