bypass

 

The original wellbore had to be abandoned before

its final usage. This wellbore is being drilled as a different

wellbore, but one which has the same target as the one that was

abandoned.

initial

 

This is the first wellbore that has been

drilled, or attempted, in a given well.

redrill

 

The wellbore is being redrilled.

reentry

 

The wellbore is being reentered after a period

of abandonment.

respud

 

The wellbore is part of an existing regulatory well.

The original borehole did not reach the target depth. This borehole

required the well to be respudded (drilled from a different surface

position).

sidetrack

 

The wellbore is a deviation from a given wellbore that produces a different borehole from the others, and whose bottomhole differs from any previously existing wellbore bottomholes.

unknown

 

The value is not known. Avoid using this value. All reasonable attempts should be made to determine the appropriate value. Use of this value may result in rejection in some situations.
