Tuned Spacer 3

A

Great Suspension properties
More accurate yield points across a wide range of temps.
Cost effective
Oil & water based muds
The rheology profile is flat across the board which promotes a wide tamp range and better displacement efficiency by providing a uniform flow velocity. No wait time as visc develops early. No CFR or bentonite needed as that would remove density.

33
Q

What makes Halliburton better.

A

Many additives are available to the whole market. WHat makes Halliburton better is the service quality and the unique developed solutions. The options Halliburton can provide are wide and vertically intergrated.

34
Q

What is the reason we don’t use API quality cement

A

Gives Halliburton the ability to play with additives to change the properties.

35
Q

Dispersants

A

Thins the slurry and reduces sheer stress by shifting the non Newtonian curve down.

36
Q

Light Weight Additive

A

Anything that will soak up water. Bentonite soaks up water(most economical way) and gilsonite takes water out. Poz comes from flyash which is basically burning coal with a SG of 2.35
Foam, nitrogen and tuned light.

37
Q

Heavy Weight Additive

A

and SG greater than 4. Anything that brigs water into the slurry.

38
Q

Mixability refers to (2 things)

A

Density

Ability to waterwet particles.

39
Q

A

Improves the bond of cement after it has gone static in the annulus.

40
Q

Super Flush

A

Reactive Fluid Flush used before primary cement operations.
Works with all water based mud and is good in low temperatures (cold weather)
When used in a “double strength” design, superflush spacer can also alleviate minor lost circulation during primary cementing.
- Helps improve mud displacement and cement bonding
-Controls Fluid Loss
- Helps prevent lost circulation and slurry migration.

41
Q

Mud Flush

A

Dispersant for clay particles and as a water wetting surfactant to chemically remove drilling mud and leave all downhole surfaces water wet.

User friendly and cost efficient.

42
Q

CFR - 3

A

Friction Reducer

reduces viscocity and improves rheological properties. as a result, turbulent flow can be achieved at lower pump rates which results in reduced friction pressure.

43
Q

Bentonite

A

Light Weight

When in water, swells to 10 times its original volume. Used to decrease slurry weight and increase volume. Makes a thick paste that also helps control lost circulation.

44

51
Q

Cement G

A

Mountain G. It is a fine grind considered premium cement.

52
Q

Tuned Light

A

LMS (Lightweight Micro Spheres) - Glass or crystal hollow beads that crush under a certain pressure once they begin to be displaced. That causes the density to increase once the LMC crush.
Creates competent cement down to 7.3 lb/gal
Provides fast strength development which will redice WOC time.
Provides lower permeability

53
Q

Well Lock Resin

A

For enhanced wellbore integrity assurance, WellLock resin delivers a casing to casing barrier in the form of a chemical packer.
The elasticity is designed to withstand pressure fluctuations. and casing expansion and contraction. Pumped ahead of cement. The resin leaves a film that increases cement casing properties 6 fold.

54
Q

Barite

A

Heavy Weight Additive for Mud and Cement. 85 lb added/ sk will produce a slurry weight of around 19lb/gal. Used to hold back high formation pressures and remove mud out of the hole.

59
Q

What is the difference between Spacer and Flush

A

Their yield point design. Spacers have a consistant yield point at many temps and shear rates. The yield point should exceed the mud’s yield point.

61
Q

Size of small silos

A
