Cement Lab Equipment Flashcards
What OS Program Does Halliburton Use For Tracking Weigh-UPs and Specfic Blend Information
I-Facts
What Does The Scanner Program Do
- Scans In Test Requests
- Checks % Tolerance for Weigh-Ups
- Provides Process Assurance If Multiple Weigh- Ups Are Needed
What Are Weigh Up Tolerances
1% Under 10 Grams
.1% Over 10 Grams
What Does The Viscometer Do
Ofite Viscometer Tests The Yield Point and the Plastic Viscosity of The Cement Blend
What Are The Viscometer Readings
3,6,30,60,100,200,300,600
What is Yield Point
The force required to get a fluid in motion, UOM= LBS per 100 square feet (300 Reading - The PV)= YP
What is Plastic Viscosity
The force required to keep a fluid in motion, UOM= CP or centipoise (The 600 reading - 300 reading) = PV
What Does Rheology Mean
Rheology Is The Study Of The Deformation and Flow of Materials Typically In A Viscoelastic State
What is A Atmospheric Consistometer
Atmospheric Consistometer performs basic consistency measurements on cement slurry samples, or conditions (shears), under elevated temperatures (up to 200 Degrees F or 93 Degrees C) at atmospheric pressure.
What is The Function of An Atmospheric Conistometer
Atmospheric Consistometer prepares (conditions) a cement slurry for free fluid (free water), static fluid loss, and other tests.
What is the HPHT Consistometer
The High-Pressure, High-Temperature (HPHT) Cement Consistometer is a device used to measure cement slurry viscosity or consistency under elevated pressure and temperature conditions.
What is the Purpose of the HPHT Consistometer
Its primary function is to determine the maximum available pumping time of a cement slurry before the slurry reaches an un-pumpable consistency before setting.
What is Halliburton’s Max Pump Thickness Before Cement Slurry Is Unpumpable
70 BC
What is API Standard for Max Pump Thickness Before Cement Slurry is Unpumpable
100 BC
What Does UCA Stand For
Ultrasonic Cement Analyzer
What Is A UCA Used For
The Ultrasonic Cement Analyzer (UCA) is a device
used to perform nondestructive compressive-strength tests on cement slurry samples
What Does The UCA Test Determine
The UCA System conducts these tests under simulated downhole pressure and temperature conditions to determine the initial set time and the wait-on-cement (WOC) time of a
slurry sample.
What Is The Initial Set Time
The initial set time is the time required for a freshly
mixed cement slurry to reach a compressive strength of 50 psi
What is WOC (Waiting On Cement)
The WOC time is the time required for the slurry to
reach a compressive strength of 500 psi. This test helps to determine how much time should be allowed for the slurry to set during one stage of a cementing operation before the next stage can begin.
How Does The UCA System Work
In a compressive-strength test, the UCA System
applies an ultrasonic (high-frequency sound) pulse to a cement slurry sample and measures the length of time required for the sound wave to travel completely through the sample. As the cement hardens, the wave travels faster and takes a shorter time to reach the other end of the sample.
What Is The Free Fluid Test
Free Fluid Test Determines If There Is Particle and Fluid Separation In The Cement Blend. Chaneling Can Also Be Seen In This Test
What Does A Fluid Loss Test Simulate
Fluid Loss Test Assembly provide a reliable way to
measure fluid loss characteristics of an oil well cement.
What Happens When There Is Poor Filtration Control
Oil well cements that have poor filtration control can
lead to a complete failure of the cemen tingoperation. In addition, the invasion of filtrates into producing zones causes formation damage, which can greatly reduce the production potential of a reservoir.
What Does A Fluid Loss Test
Fann’s Fluid Loss Testers measure fluid loss of cement slurries, drilling fluids, and fracturing fluids under elevated pressure and temperature conditions.
