Rig Matting Uses

8'x40' rig mats | Alberta

Rig Mats

1. Matting uses besides drilling

* Access roads

* Creek crossings

* Campsites

* Completions

* Walkways

* Tank Farms

* Sensitive Soils

* Land Sale Commitments

* Preference by land owners

* Staging areas

* Helicopter pads

* Protection of subsurface structures ie. irrigation lines and pipeline crossings

2. Well Site Lease Construction Options

*Dirt/gravel

*Dirt/geotextiles

*Swamp matting

-Swamp mats otherwise referred to as access mats, 3ply mats, and interlocking mats.

-8′ X 14′ – Size of each mat.

-3000 lbs – Approximate weight of each mat

-Interlocking finger system used to join matting.

-Consists of 3 layers of 2” X 8 “ boards usually bolted together.

*Rig matting

-Constructed using steel framed, wide flange structural beam welded frame with grade 2 or better spf wood members.

-Interlocking availability with some manufacturers

-Rig matting is typically used under rig substructure camp platforms, walkways, pipeline crossings

-8 X 40 rig mats 7800 lbs

3. Advantages of Matting

*Reduce lease size if there are no stripping piles required.

*Safer operations by creating level and stable work surfaces.

*Better work morale with cleaner operation and improved work ethic.

*Decreased towing required, preventing vehicle and machinery damage.

4. Inclement Weather

*Eliminates effects of unpredictable weather, ie.  rain, snow, chinooks

*Extending the drilling season allowing working through spring break resulting in faster production

5.  Environmental Management

*Solid waste handling – Dealing with invert cuttings, the use of matting reduces the total volume being treated or land-filled.

*Reduction in fluids used help rigs stay cleaner and reduces rig wash generated.

*Long term liability reduction by eliminating admixing of soils.

*Decreases ground disturbance.

*Reduces the reclamation certification timeline.

6. Improving Emergency Access

*Decreases response time for spill response, pipeline breaks, or incidents.

7. Additional Planning Requirements when using Matting

*Snow removal may be required but caution required as to not damage matting,

*Contamination from spills may limit future use.

*Cleaning considerations due to frozen mud and solids.

*Extra matting may be required for overlapping, corners, turnarounds, pullouts, and breakage.

*Having internal company co-ordination required from drilling to completions helps reduce cost.

*Trucking option consideration, winch trucks, super b’s, tridems.

*How level is the installation surface

-Undulations can make it difficult to install mats

-Matting can be used to level a lease but not recommended

-Matting with increase surface strength by spreading out the weight

8. Installation surfaces Characteristics

*Extreme muskeg.  Greater than 10 feet in depth.

*Moderate Muskeg. Less than 10 feet in depth

*Low soil stability.  Silty soils, sand, etc…

*Frozen surface frost retention.

*Water – not recommended safety and environmental may become an issue

9. Installation and Handling Techniques

*Preplan layout

*Equipment options, wheel loaders with forks and grapple.

*Trac Hoe with Mat grapple

*Skid steer for composite matting

*Proper treatment of mats will reduce maintenance costs,.

*Frozen ground may damage boards when removing them.

*Damaged mats should be set aside to be repaired.  If the structure integrity of the mat is compromised, the mat is not worth fixing.

10. Maintaining Mats

*Having a good maintenance program will increase the mat lifespan.

*Regardless of renting or owning you will have to pay for maintenance.

*Having one company look after your mats reduces maintenance costs and helps control inventory.

*Using tracked equipment on mats may increase maintenance costs.

11. Questions to ask when renting or purchasing mats

*What type of mat is best for your application; Swamp Mats, Steel mats, Laminated mats

*Sizes and weights of matting

*Expected service life

*What is the base cost

*Volume discounts available

*Deliverability time frame

*FOB point

*Matting project history, references and pictures

12. Cost Estimates

*Trucking cost to location, Tridem or super B’s

*Installation cost

*Accumulated Rental cost

*On-going costs, mat movement/maintenance

*Removal cost, pickup and trucking

*Cleaning costs

*Repairs and replacement
