    drill collar - Schlumberger Oilfield Glossary

    Drill collars are thick-walled tubular pieces machined from solid bars of steel, usually plain carbon steel but sometimes of nonmagnetic nickel-copper alloy or other nonmagnetic premium alloys. The bars of steel are drilled from end to end to provide a passage to pumping drilling fluids through the collars. The outside diameter of the steel bars may be machined slightly to ensure roundness ...

    Petropedia - What is Horizontal Drilling? - .

    Definition - What does Horizontal Drilling mean? Horizontal drilling can be referred to as the directional drilling of an oil well in a horizontal direction rather than vertical. Since most oil wells are drilled in a vertical direction, horizontal drilling helps in stimulating the well in a different way to extract most of the produce from the reservoir.

    An Introduction to Reverse Circulation Drilling

    Unlike diamond drilling, it compiles sample rock cuttings instead of rock core. The drilling mechanism is most often a pneumatic reciprocating piston called a hammer, which in turn is driving a tungsten-steel drill bit, specifically made to be able to crush hard rock. The hammer is used to remove rock samples which are pushed through the machine with compressed air. When air is blown down the ...
