SMARTSET APPLICATION AREAS




SMARTSET APPLICATION AREAS


Typically small volumes of SmartSet® 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.

* Solutions to a wide range of issues

Lost Circulation


1
Problem

Partial to total fluid losses encountered while drilling.

2
Solution

  1. Ascertain temperature @ point of loss +/- 5°C.
  2. Pickup BHA.
  3. Spot SmartSet below bit.
  4. Wait then drill though.

3
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


1
Problem

Drilling problems from unstable formation.

2
Solution

  1. Ascertain temperature @ point of application +/- 5°C.
  2. Spot SmartSet acrosszone.
  3. Pick up above plug.
  4. Wait then drill out.
3
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


1
Problem

Water flowing behind casing up through cement to perforations.

2
Solution

  1. Identify zone to be isolated and ascertain temperature.
  2. Set bridge plug below zone.
  3. Perforate casing.
  4. Set retainer above zone.
  5. Sting into retainer, perform leak-off.
  6. Displace / squeeze SmartSet.
  7. Drillout / pressure test.
3
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


1
Problem

Heavy brine / polymers damage reservoir during workover.

2
Solution

  1. Cover production zone with SmartSet.
  2. Perform workover.
  3. Drill out SmartSet.
  4. Re-perforate and / or acid wash to restore oil production.
3
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


1
Problem
Gas migration between production and surface casing.

2
Solution

  1. Isolate zone to be perforated.
  2. Perforate at top of gas zone.
  3. Squeeze SmartSet through perforations and up micro annulus.
3
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.
