7th Annual Sucker Rod Pumping
Workshop
Renaissance Hotel
Oklahoma City, Oklahoma
September 27 - 30, 2011
Fishing Fiberglass Rods in the
21st Century
Mike Poythress – Technical Manager

Fiberglass Sucker Rods
Lighter and stronger than steel
Reduces operating costs
Requires smaller size pumping units
Capital costs are reduced
Non-corrosive
Reduces down-time
Increases production – when available

Fiberglass Sucker Rod Manufacturing
Each rod has about 250 “rolls”
Each “roll” has about 400 strands of glass
fibers
Resin holds glass strands together and
forms the shape of the rod
Approximate rod composition
75% Glass fibers
25% Resin

Fiberglass Sucker Rod End Fitting
End fitting has Patented Wedges on ID
Tension applied to rod causes wedges
to be compressed between the rod and
the end fitting

Fiberglass Sucker Rod End Fitting
Epoxy is loaded into end fitting
Epoxy sticks to rod, not end fitting
Dries in about 60 minutes
Every rod is pull tested during
assembly
1.25” rods pulled to 40,000psi

Fiberglass Sucker Rod Design
Typically 40% to 60% of string is
Fiberglass
Bottom of string is steel to provide
weight
Increases downhole stroke
Some strings are “Glass and Bars”
80% Fiberglass
20% Sinker bars
24 month warranty

Fiberglass Sucker Rod Limitations
Temperature Limitations
Standard FSR 180º F
High Temperature FSR 250º F
At bottom fiberglass rod – not bottom of
well

“Hot Oil-able?”
Estimated 20% – 30% of FSR wells get
Hot Oiled
Annulus for routine paraffin removal
Tubing prior to pulling pump
180º max
Recommend a steel rod / pony rod
As with any hot oil job...don’t hot oil
today and expect to pull rods tomorrow

“You can’t fish ’em”
Permian Basin - In excess of 10,000 wells
August 2010 – July 2011
Averaged more than 15 new installs per
day in Permian Basin
FY 2011
72 Fishing Jobs
65 Caught
90.3% Success Rate
Sept. 27 - 30, 2011
2011 Sucker Rod Pumping Workshop
19
“You can’t fish ’em”
Utilize a 36’ to 40’ pump barrel
Drop down over rod part and latch onto next
upset
Challenges to catch fish
When pump is stuck in tubing
When tubing is parted
Shear tools are run on about 70% of all
installs
Some Operators choose Back off / On Off
Tools

Deviated & Horizontal Wells
Mold on Rod Guides can be installed on
fiberglass sucker rods
Not snap on guides
Rod rotators
Not a standard practice, but some
Operators choose to run in some
circumstances

FSR Case Studies
Pioneer Natural Resources study increased
production 209%, improved failure rate by
192% and reduced power consumption by
20% - 30%
ConocoPhillips study increased lift capacity
by 300%, reduced downhole failures by 85%
and reduced power consumption by 10% –
20%
