tubulars above the SET Liner?
• Will the SET Liner be covered up with another
string of pipe (is it used as a drilling liner)?
• Will the SET Liner see production fluids and/or
pressures (is there a tubing string / packer
isolation)?

72. How Does the Well Construction
Engineer Plan a Well??

73. When Approaching Well Construction …
“I will look at the offset wells or surrounding
data and play it safe ….
OR ………
“I will utilize new technology, not to get me out
of trouble, but, to add value to my well!”

74. Well Construction
Openhole operations
Design from the top down:
Many casing strings
Adequate hole size at TD for evaluation / production
Often limited at surface by riser, wellhead or BOP
High risk wells
Design from the bottom up:
What hole size is needed for evaluation or production
Minimize hole and casing sizes back to surface
Lower risk wells

75. Well Construction
Cased hole operations
Design from the bottom up:
Cover up old perfs. / re-complete
Repair damaged or corroded casing
Sidetrack
Extend the bottom of the well
Design from the top down:
But can we put a SET system up hole without losing
access to down hole????

89. Well Rejuvenation
As a result of casing corrosion, formation stress
and unwanted perforations, thousands of wells in
oil producing fields in China have stopped
production.
By using fit for purpose equipment, a very attractive
value proposition is being realized.
Liner lengths ranging from 75 to 260 ft with setting
depths from 1,650 to 10,400 ft are being installed.
