Q

SD Spacer

A

Spacer Used to remove water based mud. For Oil based, a surfactant must be added. Low viscosity so it can achieve a turbulent flow. CFR or bentonite may be added to pump faster and maintain flow patterns.

Tuned Spacer 3
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.
26
Erodability
The measure of how easily a drilling fluid is removed from the wellbore. I.e. TS3 increases erodability when removing problematic material.
27
Expansion Additives
Expand after cement goes static. It promotes bonding and helps with zonal isolation and the formation of micro annuli. Microbond and Super CBL
28
Microbond
Expansion Improves expansion properties in low temps and with weaker cements like cheaper 50/50 poz.

33
What makes Halliburton better.
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
What is the reason we don't use API quality cement
Gives Halliburton the ability to play with additives to change the properties.
35
Dispersants
Thins the slurry and reduces sheer stress by shifting the non Newtonian curve down.
36
Light Weight Additive
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
Heavy Weight Additive
and SG greater than 4. Anything that brigs water into the slurry.
38
Mixability refers to (2 things)
Density | Ability to waterwet particles.
39
Expansion Additives
Improves the bond of cement after it has gone static in the annulus.
40
Super Flush
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
Mud Flush
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
CFR - 3
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
Bentonite
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
D-Air 3000L
Defoamer Does not affect fluid loss, thickening time or compressive strength. Can provide good foam control even in slurries with high yield points.
45
Versaset
Thixotropic Additive Helps control free water and promote high early strength and help control fluid migration.
46
Gilsonite
Lost Circulation Does not shatter when perforated. Can provide higher strength than heavier additives with higher water requirement.
47
Poly-E-Flake
Lost Circulation additive. Also used in the spacer to check for returns or channeling.
48
SCR-100
Retarder. Helps to simplify the design of thixotropic slurries.
49
Foam Cement
- High Quality, Low Density Slurry - Increases the set cement elasticity - Increases liquid state compressibility - Cost Effective - Able to respond to last minute density changes.
50
Poz (Fly Ash)
Made out of burned coal. Helps lighten the slurry and helps its pumping properties. Helps reduce the permeability Helps cement resist sulfate Minimal mixing water and can provide good expansion properties Has a nearly universal economic application to oilwell cementing
51
Cement G
Mountain G. It is a fine grind considered premium cement.
52
Tuned Light
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
Well Lock Resin
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
Barite
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.
55
Clean Spacer 3
Weighting agent - SSA Viscosifier - SA 1015 Consinstant rheo profile with zero hydration period. Used when customers are sensitive to price and want to stay away from TS3. Flat profile along a large shear and temp range.
56
Advantages of CS3
low COGS Improves cleaning at lower velocity predictable rheologies zero hydration time
57
Potential extra costs incurred without proper mud disp
``` Mud Reclaimation Remedial Cementing (Top out, squeeze) Additional Rig time Lack of zonal isolation lawyer fees, bad PR, corrosion problems channeling- gas migration ```

59
What is the difference between Spacer and Flush
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.

65
Are all jobs loaded from the top?
Tuned light is loaded from the back and blended at a lower PSI to prevent the microspheres from collapsing before they are designed to.
