Which of the statement is true about Pneumatic drilling fluids
Key to this-A, B, C, D
EXPLAINATION::
Pneumatic fluids are like air, gas or foam type
Because of their low density they impart low pressure to formation, loss circulation problem is usually very low.
Air, being less reactive to reservoir fluid or formation, formation damage is also very low.
Fire occurs when Fuel+O2+ spark source
Corrosion occurs when, electrolyte+O2+metal present in the system.
In both of the above cases O2 or oxidation type environment may be generated because of air used as pneumatic drilling mud.
Fire will be created if reservoir gases as a kick within explosive limit comes in contact with O2in presence of spark.
Corrosion may also happen because of producing reservoir water reaction with metallic tubing/equipment in presence of O2 from pneumatic drilling mud.

๐โHow to overcome the foamy crude phenomenon inside Seperatorsโ
๐There are many ways to overcome this phenomenon in oil and gas separators, such as installing Defoaming Plates which are inclines parallel plates which are to close to each other, when foamy crude flows through these plates, oil droplets are collected when hitting these plates and the gas is liberated. Provide additional surface area, which breaks up the foam and allows the foam to collapse into the liquid layer but some resources say that Installation of defoaming plates to combat foam is normally not effective and may even be counterproductive. โฆ๏ธFoaming in the vessel is minimized by decreasing the downward liquid velocity, for instance by increasing the diameter of the separator vessel. We can also use foam depressants or defoamers, these chemicals are rather expensive, we can also reduce or break foam by other means such as heat or centrifugal force.
