Top DrivesTop DrivesTop DrivesTop Drives

+ Use of longer stands in the derrick (3 instead of 1 joint)

+ Quickly engage the pumps or the rotary while tripping pipe

+ Back reaming

+ Washing and reaming

+ Decease possibility of “stuck pipe”

+ Less joint connection has to made

+ Well control improvement

- Most frequently reason for

NPT

- Higher Dayrate

- Derrick capacity reduced

- Lack of experience of rig

crew

- More wear on drilling line
