Quality Racking Mat

Quality Rental Tools

Old vs New

Safety• Reduced slips & falls!

– #1 cause of lost time accidents!

• Reduced hand injuries!– Significant to Shell’s hands-free initiative!

• Reduced eye & skin injuries!– Loose boards result in chemical splash to

eyes and skin.

Quality Rental ToolsCase Study: Mat 3 – Mat 4Mat 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 mashingof polypropylene material) and no structural damage to mat grid

8 ½” collars 4 stands, 5 ½” HT-55 hevi-weight 7 stands, approximately 180stands 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 weighttotal = 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 15minutes up to 1 hour for deeper trips. Over the 5 ½ month period, this equatesto approximately 2-3 days of rig time saved.

o Deepwater applications: @ a day rate of $500K/day on drill shipapplications, 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.

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 PipeAverage Cost of SBM = $250.00/bblResults in a savings of $4,500.00 per trip16 trips = $72,000.00 savings during the drilling operation

•3 well drilling program would result in a total savings of $226,000.00

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

Cost Savings – RecutsDrilling

– Current recut rate of 15%– Average recut cost for premium connections is $800.00– QRT Racking Mats will reduce recuts by at least 50%– Result in a savings on a 30,000ft operation of $85,600.00– Yearly cost savings of $214,000.00

Completions– Current recut rate of 50%– Average recut cost for premium connections is $800.00– QRT Racking Mats will reduce recuts by at least 50%– Result in a saving on a 30,000 operation of $285,600.00– Yearly cost savings of $714,000.00

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
