In order to separate the gas effectively in the drilling, so an efficient degasser is essential to the safe and productive drilling operations. Since gas is practically insoluble in water, it is relatively easy to detect and remove. By comparison, gas is easily soluble in oil-based muds to detect and remove it are both more difficult. Regardless of the composition of the gas encountered, gas existing in the mud can decrease efficiencies in rig pumps, centrifugal pumps and associated operational equipment. The goal is to “Keep the pumps operating”.
Atmospheric separation relies on impact, turbulence, agitation or a combination of these techniques to separate gas from the fluid. It possesses few moving parts and have low initial cost. But their efficiency is limited and they may not be suitable for all conditions.
Differently, vacuum degasser has more moving parts and higher initial cost. This is due to the vacuum pump and attendant components primarily. They are, however, much more efficient. Because gas volume is inversely proportional to pressure, gas bubbles in the fluid is more rapid under pressure. By combining impact and turbulence these features with low pressure, modern vacuum degassers proves fast and highly effective in the aspect of separating dissolved gas.
As the purification equipment of oil & gas drilling fluids solids control system, vacuum degasser actually is used to remove little invaded gas in drilling mud. It will be set between shale shaker and mud cleaner/desander. Vacuum degasser separates the gas that migrates into the drilling fluids by the function of vacuum pump and vacuum tubular tank. If the gases have not been separated from the drilling fluids, it may cause well kick, and increase the total financial cost and time spent on the drilling project. If there is no gas migrating into the drilling fluids, the vacuum degasser would work as a big mud agitator, to enhance the shearing rate of the drilling mud.
