Question 1. What Is The Function Of Mud?
cool and lubricate the drilling bit
convey slicing from the lowest of the hole to the floor
Drilling mud know as hydrostatic pressure which allow to govern
the formation strain
Clean drill bits ,drilling mud removes reducing from bit teeth which
save you bit ball up scenario
save you formation harm by using using appropriate drilling mud
Transmit hydraulic horsepower to the bit
To keep away from bit to balled up
Question 2. What Is The Functions Of Shale Shaker,desander,degasser,dust Cleaner,deselter And Center Fuger?
Shale shaker: remove massive reducing from dust (74 micron
Desander: do away with sand from mud much less than (seventy four -40micron operating strain (35-45) psi. Potential 500gpm/cone
Deselter : eliminate salt from dust much less than (40 - 20 micron
Working pressure (35-45) psi. Ability 75 gpm/cone
Degasser : eliminate gases from dust.Working strain (35-45) psi
Mud purifier : remove slicing from 20 micron to 7 micron
Center fuger :eliminate reducing from dust much less than 7 micron to 4

Question 5. What Are The Steps To Check On Mud Pump?
Permit to work
Per task protection assembly
Electric isolation and put safety lock in the back of pump
Close discharge valve - open bleed valve -then near suction valve
Check pump and replace parts
Remove equipment from pump region
Open discharge valve-closed bleed valve-open suction valve
Remove protection lock and isolation
Cleen cooling tank and fill it
near work allow

Close paintings allow
Mechanical Interview Questions
Question 13. What Time Of Greasing Crown?
Question 14. How You Can Calculate Mud Tank Size?
Lenth* width* peak =…/5.614 =…. Bbls
Question 15. What’s The Hydro-static Pressure?
Ph is the strain exerted by way of the burden of a liquid on its “field
Ph is the pressure exerted by way of the drilling fluid to offset the strain exerted through the formation fluid
Ph (PSI) = zero.007 * TVD (feet) * Mud wt. (pcf)
Ph (PSI) = zero.052 * TVD (ft) * Mud wt. (ppg)
Sufficient hydrostatic pressure is required to prevent the borehole wall from caving in and to preserve formation fluid from getting into the wellbo

Question 16. What Is The Relationship Between The Water Losses And Filter Cake?
Filter cake growth with water losses boom
Question 17. What Will Happen When Sand Found With Drilling Mud?
Damage in pump elements
Rig down time
Cause bit nozzle plug
Reduce rate of penetration
