George Boyadjieff is
a leading developer of offshore drilling technology, and has been
awarded more than 50 patents over the past 30 years. He is best known as
the inventor of the Top Drive Drilling system. This system has made a
step-change in drilling efficiency and has been credited with enabling
the construction of many wells previously believed to be undrillable.
The top drive
drilling system rotates the drillstring directly from the derrick and is
permanently connected to the mud circulating system and the traveling
block. This allows drillpipe to be introduced in multijoint stands,
resulting in greatly improved drilling efficiency and safety. Top Drives
also improve operational performance while drilling highly deviated or
horizontal wells and when running casing.
