Drilling as per the drilling program can sometimes be disrupted by major issues, such as extreme
to total mud losses (e.g., those happening in cavy formations) and sloughing and swelling of
shale. Such problems may lead to narrowing wellbore diameter due to installation of additional
intermediate casing in the troublesome formation to overcome the problem, more complicated
wellbore designs, extensive loss of drilling time, high cost and finally, shutting off well.
All this can be simply avoided through utilizing Wildcat’s Profile Liner (expandable casing), which
will help you drill any troublesome formation accompanied with high mud losses or sloughing
and swelling of shale without narrowing your wellbore diameter while saving rig time and cost.
Wildcat's profile liner can be considered to be a part of the drilling program as to avoid installing
additional casing while drilling known troublesome formations and reduce expected drilling
time.
