Casing shoes are used for drilling down or positioning the casing
tubes in a borehole.
Surface-Set Diamond Bits:
1: Surface-Set Diamond Bits are set with a singular layer of
natural or synthetic diamond utilizing a hard matrix compound on
the face of the bit. The diamond set design ensures sufficient
overlap to prevent premature wear of the matrix.
2: Surface-Set diamond bits are primarily recommended for use in
drilling relatively soft, abrasive, unconsolidated formations that
are not effectively drilled by impregnated diamond bits. They are
also recommended for use in drilling harder formations where the
available rotational speeds and bit loads are insufficient to use
impregnated diamond bits due to drilling equipment limitations.
Surface-set bits Diamond Grades:
Diamond grade is the most important factor to take into
consideration when selection a surface set diamond core bit, as it
affects bit price and total meters drilled, and therefore obviously
affects cost per meter drilled. Number of stones is also a very
important factor orienting the bit selection too through
determining how well a bit will cut. The natural diamonds utilizing
for surface set diamond bits have been selected carefully, and
precise pattern has also been used to set each diamond on bit
cutting area to ensure proper overlap with a minimum of diamonds to
keep the carat weight (the initial bit cost) as low as possible
