Q

What is Squeeze Cementing

A

Process of applying hydraulic pressure to force or squeee cement into perforations and force filtrate water to create a solid mass known as a rope

Q

What is A High Pressure Squeeze

A

Surface pressure+displacement fluid hydrostatic pressure+ cement slurry hydrostatic pressure= total bottom hole pressure greater than formation fracture pressure

Q

What is A Hesitation Squeeze

A

Concerned with gel strength development, false indication of squeeze pressure, difficulty reversing out, high pump pressure coule cause formation breakdown

Q

Why is Pressure Applied on Annulus During Squeezes

A

To protect the casing from collapsing and to keep the packer set and in place

Q

What are Two Types of Squeeze Method Placements and Definition

A

Packer- Isolates casing above therefore higher squeeze pressure can be applied. Pressure needs to be applied in order to prevent casing collapse

Q

Causes for Cement Slurry Failure

A

Contaminated material, incorrect volume of mixing water, incorrect amount of chemicals

17
Q

Causes of Cement Channeling Failure

A

Failure to centralize pipe, move pipe during the cementing job, circulate mud before cementing job

18
Q

Definition of Densitometer

A

Devise installed on pumping truck manifold to measure the density of fluids

19
Q

What Does The Recirculating Densitometer Do

A

Regulates the ADC

20
Q

Purpose of A Vacuum Breaker

A

The relieve negative pressure

21
Q

What are some features of Super Seal II High-Port Up-Jet Float Shoe

A

Improves mud displacement, provides excellent filter cake removal, up jets 60% of fluids volume

22
Q

Reasons for Multi-Stage Cementing Equipment

A

Hydrostatic pressure too great for formation/casing, separate different types/blends of cement, or there is a limited pump time

23
Q

What is a Poppet Valve

A

Most popular type of valve in the Halliburton Float Equipment, 2 3/4 and 4 1/4 sizes are available for the SSII

24
Q

What is HMS Procedure for Cementing

A

Obtain casing/drill pipe burst/collapse pressures and safety factors to calculate max allowable pressure, not exceeding 80% of rated value of new pipe, obtain body yield strength of casing/drill pipe, do not exceed 56% of rated value of new pipe.
