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.
