16
Q

What Is A UCA Used For

A

The Ultrasonic Cement Analyzer (UCA) is a device

used to perform nondestructive compressive-strength tests on cement slurry samples

17
Q

What Does The UCA Test Determine

A

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.

18
Q

What Is The Initial Set Time

A

The initial set time is the time required for a freshly

mixed cement slurry to reach a compressive strength of 50 psi

19
Q

What is WOC (Waiting On Cement)

A

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.

20
Q

How Does The UCA System Work

A

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.

21
Q

What Is The Free Fluid Test

A

Free Fluid Test Determines If There Is Particle and Fluid Separation In The Cement Blend. Chaneling Can Also Be Seen In This Test

22
Q

What Does A Fluid Loss Test Simulate

A

Fluid Loss Test Assembly provide a reliable way to

measure fluid loss characteristics of an oil well cement.

23
Q

What Happens When There Is Poor Filtration Control

A

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.

24
Q

What Does A Fluid Loss Test

A

Fann’s Fluid Loss Testers measure fluid loss of cement slurries, drilling fluids, and fracturing fluids under elevated pressure and temperature conditions.

25
Q

What Does The Multiple Analysis Cement System Do

A

The Multiple Analysis Cement System (MACS II®) is an instrument that performs static gel strength (SGS) tests on cement slurry samples. Rapid static gel development (short transition time) indicates good gas migration control.

26
Q

How Does The MACS II Work

A

The MACS II accepts a sample of cement slurr and applies a controlled set of temperature, agitation, and pressure parameters that simulate the down-hole conditions of a well. During testing, it monitors, controls, and records these parameters to form a data set. This data can then be analyzed to assist in predicting the performance of cement slurry in a well.

27
Q

What Does The MACS II Determine

A

Zero Gel Time/Transition Time

SGS/Time

28
Q

What Is Zero Gel Time

A

zero gel time is from 0 to critical static gel strength

.

29
Q

What Is The Transition Time

A

Transition time is determined by the critical static gel strength to 500 lb/100ft2

30
Q

What Is Halliburton’s Expectations for Cement Slurry Transition Time

A

30 Minutes

31
Q

What Is API Standards For Cement Slurry Transition Time

A

45 Minutes

32
Q

What Is The Chandler Model 4207D Cement Cube Crusher

A

4207D Compressive Strength Tester is an automatic, digitally-controlled, hydraulic press. It is designed to test the compressive strength of standard two-inch cement cubes in exact compliance with API Spec 10A.

33
Q

What Does The Cement Cube Crusher Test

A

The unit is used in research and field laboratories involved in quality assurance, and strength testing of cement blends.

34
Q

What is Free Fluid Loss Halliburton Standard for Surface and Intermediate Casing

A

Less Than 300 CM3/ 30 Minutes

35
Q

What is the Free Fluid Loss Halliburton Standard for Production Casing

A

Less Than 100 CM3/ 30 Minutes

36
Q

What is the Free Fluid Loss Halliburton Standard for Liners

A

Less Than 50 CM3/ 30 Minutes

37
Q

Horizontal Wells

A

Less Than 50 CM3/ 30 Minutes

38
Q

What % Free Fluid Separation Does Halliburton Want To See In A Free Fluid Test

A
