Objectives
On completion of this module you will be able to:
•Describe the four primary kick-off methods
•Explain where and why each method is preferred
•Design a BHA for each type of method
•Select appropriate Bits for the chosen technique
•Work as a second hand on a kick-off operation

What is a Kick-off
A kick-off is the deflection of wellbore
while maintaining control of Azimuth,
Inclination and DLS.

Kick-off Methods
The following are methods of Kick-off:
•Jetting deflection
•Whipstock deflection
•Motor deflection
•Rotary Steerable deflection

Jetting
Jetting is the utilization of hydraulics to wash a pocket
beneath and to the side of the bit to cause deflection.
Jetting was, until recently considered redundant.
However with the increased requirement to exit
mature platforms where clearances between wells
are too tight to utilize anti-collision practices with
steerable motor systems, jetting has become the only
economic alternative.

Jetting Bits
Two cone jetting bits like this
one from RBI
®
are
available but rarely seen
in the field:

Jetting Bits
Conventional roller cone bits
are commonly used for
jetting and are adequate
for the task :

Jetting BHA
BHAs for jetting need to be designed on the principles of
conventional “Rotary Build BHAs”:
•Jetting Bit (oriented)
•Near Bit Full Gauge Stabilizer
•Orientation Sub (UBHO) (dependent on measurement
tool)
•Up to 3 Drill Collars ( 12” to 26” hole) or (MWD + 2
DCs)
•String Stabilizer (optional, as is gauge if present)
•Transition string, jars etc. as required

Jetting Procedure
The steps to follow are:
1.Orient BHA prior to commencing (Scribe or
survey)
2.Come on bottom using maximum flow rate
(>500’/sec)
3.Spud for +/-6’ (2m)
4.Rotate remainder of double at reduced flow
rate.
5.Survey (if retrievable tool or use cont. D&I if
MWD)
6.Adjust orientation and distance spudded as
required

Whipstocks
Whipstocks are highly effective tools designed to
provide lateral displacement from the well-bore.
They do not give very large changes in dogleg but due
to the fact that what is provided is done in a very
small change in MD. They generate high DLS
values.
Though whipstocks are a niche market tool their range
and diversity is on the increase.

Whipstocks
Whipstocks come in five primary types:
•Open Hole Retrievable Whipstocks
•Open / Cased Hole Cemented Whipstocks
•Open Hole Packer Whipstocks
•Cased Hole Mechanical Set Whipstocks
•Cased Hole Hydraulic Set Whipstocks
