The best information in your pocket about Drilling problems interview
    Sometimes we need a lot of interview questions to be always ready for the interview
    This exam was in one of the personal interviews of one of the oil companies,and we collected many responses that you can read now 
    and benefit from.

    What is this? How can we prevent this from happening again?


    The First Contestant:
    Adjacent wells or field experience should clearly dictate the change of some of the mud properties, specially from water base to oil base mud to prevent the clay balling of your bottom hole assembly and bit !!

    The second Contestant:
    0.75 saw dust sacks a connection add TKPP "is a highly soluble, more environmentally friendly, low sodium" over circulation until 100 m from TD when rope starts to slow down smoke the bit on bottom with a fresh water and saw bust sweet work pipe a couple times after sinking it drill around 80  m/hr

    The Third Contestant:
    Normally why touching such formation, we change the drilling fluids properties like adding oil to drill fluids.

    The Fourth Contestant:
    This happened because they drilled into a formation containing clay with water-base mud instead of oil-base mud.

    Fifth Contestant:
    Lots of pump and well coated drill string with proper lubricants to keep it from binding to the assembly is all you can hope for.

    Sixth Contestant:
    Not much you can do to prevent this from happening on your trip out of the hole through clay sections. Normal in many parts of the world.

    The seventh Contestant:
    Turn your fresh water off in the mud tanks, raise your PH as high as you can get it and pump a lot of PHPA"A class of water muds that use partially-hydrolyzed polyacrylamide (PHPA) as a functional additive" sweeps, run low gallons per minute and as much rate of penetration as you can get! 

    Eighth Contestant:
    Soap sticks on connection and PHPA"A class of water muds that use partially-hydrolyzed polyacrylamide (PHPA) as a functional additive" sweeps. Kick up the RPM and hope that you can keep those junk slots clean or you’ll be pulling for low ate of penetration when in reality you’ve got a green bit. 

    Ninth Contestant: 
    Soap/sap helps in the beginning but it will overtake. With aggressive drilling programs these days the faster you drill the lesser the whole cleaning. Before you know it it’s swabbing out of the hole with sticky drag. 

    Tenth Contestant:
    Soap SAPP "Abbreviation for sodium acid pyrophosphate, a sequestering agent used to treat cement contamination and a deflocculant "Deflocculants are substances which prevent flocculation by increasing zeta potential and therefore the repulsive forces between particles" for low-temperature water muds" polymers if it’s sticking to the shaker screen it’s sticking to the bit the pipe and you are taking a chance of plugging the flow line soap lots of soap

    Eleventh Contestant:
    Bit balling: treat with additions of soap to help prevent sticking and concentrated sweeps of walnut hulls, various sized calcium carbonate, and sometimes lignite.

    Twelveth Contestant:
    Pump lots of saw dust helps prevent mud rings and balled up bits.
