who is grit
Who is Grit?

Private Technology, Manufacturing and

Service Company with 3 Divisions

  • A-Fire Burners – conventional, natural drafted, flame arrested, burner systems
  • Cold Weather Technologies – new indirect heating process
  • Grit Fabricating – containment, metals fabrication, treating, and solids handling

Associated with Sand Control Systems

– Tank Cleaning and Sand Handling Systems

our roots are in heavy oil
Our roots are in heavy oil.

Most of our products have been developed for, or derived from, the heavy oil industry.

what does the grit fabrication shop do
What does the Grit fabrication shop do?
  • Specialized steel fabrication and manufacturing.
  • Engineered steel secondary containment systems.
  • Steel fencing systems. custom roll forming line
technology research and development
Technology research and development
  • The fabrication shop is the home for most of the Grit R&D
  • Much of the revenue from sales is reinvested in technology development
plasma cutter
Plasma cutter
  • Plate cutting capability up to 10ft W x 24ft L.
  • Plate thickness cutting capability – 18ga material to 1-1/4 inch plate.
  • Cutting accuracy to within 0.010 of an inch.
  • Cutting repeatability to within 0.005 of an inch.
water jet cutter
No “heat affected zone” - effectively minimizing the impact of the cut on the inherent structure or properties of the material.

Narrow cut, and a pressure of 87,000 psi

Can slice through a thickness of up to 8”

Can work with a wide range of materials, from steel to plastics.

Water jet cutter
roll form mill
Grit Roll Form Mill

Grit has a large roll form mill capable of molding panels from material as thick as 10 gauge

Roll-form mill
custom fabrication and engineering work
Custom fabrication and engineering work
  • Hydraulic Equipment
  • Various custom made devices and systems
secondary containment
Secondary containment
  • Grit G-55 Secondary Containment Systems
  • Grit has designed a secondary containment system that specifically addresses legislation and guidelines on environmental spill protection.
grit fabrication
Grit fabrication
  • Various breaks and benders,
  • Welding services,
  • Hot tapping,
  • Sand blasting and painting.
fabricating sand management and solids handling equipment
Fabricating sand management and solids handling equipment
  • Grit builds sand management equipment for Sand Control Systems and others
  • Grit are expert at solids management.
  • Systems are in place around the world for managing produced sand, catalyst, and other solids
environmental protection system
Environmental Protection System
  • Grit Industries Inc. has designed a secondary containment system specifically for the oil industry.
  • The G55’s modular design can be configured to many shapes and is well-suited for space-restricted installations.
  • The system is self-supporting, free-standing and virtyally maintenance free.
advantages of g 55 secondary containment
Advantages of G-55 Secondary Containment
  • Engineered and tested design with a full range of sizes, heights and layouts available,
  • Available in 12 and 14 gauge galvanized steel panels,
  • Requires a minimum of fasteners for assembly,
  • Both top- and base-mount liner attachments are available complete with all necessary hardware and sealant, and
  • Four inch wide top flange helps eliminate accidental injury.
mpt what is the mechanical production treater
MPT: What is the Mechanical Production Treater?
  • 45‘ heat exchanger (condenser) between well and tank
  • 10” flowtube inside a 14” shell
  • Auger/mixer/separator slowly turning in flowtube (≈ 1rpm)
  • Heat supplied by the Heat Driven Loop
  • Gas separated prior to the tank
  • Chemical injection upstream of treater
mpt first pilot in lashburn area well
Pilot test in “problem high sand, foamy well”

30 m3/d @ 30% (2.5%)

Unable to heat past 60º

Short loads due to foam

Sales cut 25-30%

Sales cut 2% solids

High solids cut required delivery to a more distant facility

MPT: First pilot in Lashburn area well
mpt pilot 1 lashburn area well results
Significant device modifications during test – a learning process

Tank is now consistently over 80º

Foam problems resolved

Sales cut 0.4 – 1.5%

Sales cut trace solids

Fuel Consumption = 84% of conventional system previously in use

Oil to nearby facility

Dependable

Fluid Thermal Efficiency – 58% versus immersion tube efficiency of 32%

MPT: Pilot 1 Lashburn area well - Results
mpt second pilot in lone rock area
Pilot test in good well

20m3/d @ 30% (trace)

Whole purpose of test was to determine if the device could consistently treat clean in a single tank

MPT: Second pilot in Lone Rock area
mpt second pilot in lone rock area1
Consistently treats clean (<0.5% BS&W) in single tank

Has been dependable and easy to operate but has had some problems with wet gas on location

MPT: Second pilot in Lone Rock area
mpt encana provost
MPT: Encana Provost

Plant Evaluation Trial

  • 2 MPT’s installed at a field header on a test/interim basis while waiting for a cleaning plant to be completed
  • Test ran for ≈ 90 days
  • Typical Oil – 74 m3/d
  • Typical Water – 65 m3/d
  • Average input W/C - 46%
  • Demulsifier at 130 ppm
  • The MPT consistently produced clean oil from sales tank

MPT: Encana Provost process layout

Mechanical Production Treaters

mpt ccs and cnrl slop management
MPT: CCS and CNRL slop management
  • Slop treating facilities
  • Continuous once through process
  • Cleaning slop and/or cavern material to less than 0.5% by volume
  • Current rate is 35 m3/d (40% - 5% sand)
mpt why does it work
MPT: Why does it work?
  • Very efficient heat transfer.
  • Good chemical distribution
  • Short vertical travel distance for oil, water, and sand droplets while in flowtube
  • Removes the gas prior to the tank (reduced turbulence in tank)
  • No firetube related convection in the tank
  • Augured tank cleaning reduces cleaning turbulence
  • 10” flow tube reduces fluid velocity entering the tank
  • Quiescence in tank
