THERMO SET®
Thermo-Setting Technology for Well Integrity , Drilling Efficiency
THERMOSET® APPLICATION AREAS
Typically small volumes of ThermoSet® slurry are required to achieve the desired results – often less than one cubic meter for remedial applications. Slurries are mixed at the well site under supervision of a Pluto engineer and pumped downhole using conventional techniques and equipment.
Lost Circulation
Problem
Solution
Result
Problem
Partial to total fluid losses encountered while drilling.
Solution
- Ascertain temperature @ point of loss +/- 5°C.
- Pickup BHA.
- Spot SmartSet below bit.
- Wait then drill though.
Result
Circulation restored. Continue drilling to total depth.
Benefits
- Ideal for carbonates.
- Pumped through the bit and mud motors – no need to pull BHA.
- Liquid to solid in 120 seconds at set point.
- Ready to drill out in 2 hours after placement.
- Withstands 30% contamination without affect on setting characteristics.
Wellbore Stabilization
Problem
Solution
Result
Problem
Drilling problems from unstable formation.
Solution
- Ascertain temperature @ point of application +/- 5°C.
- Spot SmartSet acrosszone.
- Pick up above plug.
- Wait then drill out
Result
A stable zone and gauge hole.
Benefits
- Pumped through the bit – no need to pull BHA.
- Ready to drill out in 2 hours after placement.
- Easy to drill.
- Withstands 30% contamination without affect on setting.
- Leaves gauge hole over treatment length.
Water Flow Shut Off
Problem
Solution
Result
Problem
Water flowing behind casing up through cement to perforations.
Solution
- Identify zone to be isolated and ascertain temperature.
- Set bridge plug below zone.
- Perforate casing.
- Set retainer above zone.
- Sting into retainer, perform leak-off.
- Displace / squeeze SmartSet.
- Drillout / pressure test.
Result
Oil production restored without water.
Benefits
- Can be pumped easily through perforations.
- Easy to drill.
- Set point allows a known calculated squeeze volume.
- Pressure in crease at setpoint indication of job completion.
Temporary Plug to Protect Producing Formation
Problem
Solution
Result
Problem
Heavy brine / polymers damage reservoir during workover.
Solution
- Cover production zone with SmartSet.
- Perform workover.
- Drill out SmartSet.
- Re-perforate and / or acid wash to restore oil production.
Result
Pressure test and resume oil/gas production after drill out.
Benefits
- Can be set with coil tubing (extremely low friction pressure).
- No damage to formation.
- Plug will hold formation pressure.
- Well returned quickly to production.
- Workover rig time minimised.
- No transition / channeling between fluid and set point.
Surface Casing Vent Flow
Problem
Solution
Result
Problem
Gas migration between production and surface casing.
Solution
- Isolate zone to be perforated.
- Perforate at top of gas zone.
- Squeeze SmartSet through perforations and up micro annulus.
Result
- Surface vent gas flow eliminated.
- Drill out and pressure test if desired.
- Perforations shut off with SmartSet.
Benefits
- Low-viscosity, thin slurry with small particle size easy to place in micro annulus.
- Environmentally friendly and non-toxic to ground water.
- Right angle set stops gas.
- Does not dehydrate drilling squeeze displacement.
