This document summarizes the benefits of Quality Rental Tools (QRT) racking mats: 1. QRT racking mats reduce slip and fall injuries, hand injuries, and eye and skin injuries for rig workers by providing a non-slip surface and containing drilling fluids. 2. Case studies found that QRT mats saved rig time through faster pipe cleaning and reduced repairs, saving up to $1.5 million per day for deepwater rigs and up to $450,000 per day for shelf rigs. 3. User feedback found that QRT mats reduced connection refacing repairs by 50% or more, saving up to $214,000 per year for drilling operations

6. Clean Threads
QRT
• Reduces exposure to
hand injuries!
Less handling of pipe
for cleaning and
doping.
• Requires less power
washing.
Resulting in less
contaminated water
requiring disposal.
• Reduction in recut cost.
Due to zero embedded
trash.

Case Study: Mat 3 – Mat 4
Mat Specifications
• Mat 3: SIZE 7’6” X 6’ 10”
• Mat 4: SIZE 6’9” X 6’ 11”
• Interlocked polypropylene grid
Application data
• Case study based upon both mats in deepwater semisubmersible rig
applications, with exposure to most extreme drilling conditions (recorded)
• Mat 3 is on driller’s side of rotary table; Mat 4 is on opposite side of rotary
table
• A 30” bit with a 12” motor has been placed on mats, equaling approximately
25,000 pounds of total weight with minimal impact observed (minor mashing
of polypropylene material) and no structural damage to mat grid
• 8 ½” collars 4 stands, 5 ½” HT-55 hevi-weight 7 stands, approximately 180
stands HT-55 drill pipe.
o Total weight of collars, hevi-weight and drill pipe (Mat 3) =
350,000 pounds (mat 4 holding the remainder) Tubular weight
total = over 500,000 lbs
• Both mats in operational use 5 ½ months, with approximately 150 trips made.
Only minor adjustments needed during subsequent rig shut-down
• Client testimony indicates a time savings on cleaning and re-doping from 15
minutes up to 1 hour for deeper trips. Over the 5 ½ month period, this equates
to approximately 2-3 days of rig time saved.
o Deepwater applications: @ a day rate of $500K/day on drill ship
applications, a cost savings of $1M to 1.5M
o Shelf applications: @ a day rate $150K/day on jack-up applications,
cost savings up to $450,000.
Repairs
• Client reported low repair ratio on HT-55 connections. 1,238 connections
with 63 repairs needed (6%)
Fluids
• 14.5 Synthetic base mud. 14.0 calcium bromide. No pitting reported.

10. User Feedback:
Since installing the racking mats on Nabors 623, we have seen a noticeable
decrease in the number of reface repairs on our pin end connections. Also
have been recovering an average of 30 bbls of OBM per trip out of the hole on
our deeper jobs in Jefferson and Hardin Co. The rig floor stays cleaner and
less of a slip hazard with all the OBM from the ID of the drill pipe being
contained and transferred back to the active system.
Prior to installing the racking mats we had an average reface repair rate of
33% (221 pins – 72 reface repairs) on our 4” XT-39 DP.
Our recent numbers are 11.5 % (190 pins – 22 reface repairs) and 15% (78
pins – 12 reface repairs) on XT-39 and 2-7/8” WT-23.

Cost Savings - Containment
•Drilling fluid treatment and conditioning.
•Reclaiming SBM, OBM or WBM.
•Reduction in fluid contamination and treatment of 18 bbls per
trip.
1/32” = 0.10 bbls/stand of 6 5/8” 34# Drill Pipe
Average Cost of SBM = $250.00/bbl
Results in a savings of $4,500.00 per trip
16 trips = $72,000.00 savings during the drilling
operation
•3 well drilling program would result in a total savings of
$226,000.00

12. Cost Savings – Disposal
• Reduced disposal cost due to total
recovery.
• At $20.00 per bbl disposal cost, averaging
5 bbls per day – daily savings of $100.00.
– $100.00 day
– $3,000.00 month
– $36,000.00 year

14. Cost Savings - Rig/Labor
• Client experience has show a reduction in make-up of from 15
minutes to 60 minutes per trip, depending on depth.
• At a savings of just 41.5 minutes per trip the savings over one
year period:
• 20,000ft / 120ft = 166 stands
• 166 x 15 seconds = 2,490 seconds per trip
• 2,490 seconds = 41.5 minutes per trip
• 150 trips per year = 6,225 minutes = 103.75 hours = 4.33
days
• Deepwater @ $1,200,000.00 per day - $5,196,000.00
• Shelf @ $150,000.00 - $649,500.00
