    FAQ:

    1. What is drill casing?

    Casing is a large diameter pipe that is assembled and inserted into a recently drilled section of a borehole. Similar to the bones of a spine protecting the spinal cord, casing is set inside the drilled borehole to protect and support the wellstream.


    2. Why is overburden important?

    Because of the higher temperatures at deeper depths, the overburden rock in a petroleum system sits on top of the source rock and aids in its thermal maturation. A heating rat's pace of burial is determined by the age and thickness of the overlying rock, which also affects it.

    3. How far can you directional bore?
    What are the minimum and maximum lengths of crossing? Maximum lengths and hole diameters are determined by project specific geotechnical conditions however effective outside range for heavy rig horizontal directional drilling is 3,000 m
