General Concepts

Question 1

What is metallurgy in well engineering?

Answer 1

Metallurgy is the study of metals, focusing on their properties, performance, and how they can be used in well construction to ensure safety and durability.

Question 2

What is corrosion?

Answer 2

Corrosion is the process where metal is damaged by chemical reactions, often caused by oxygen, CO2, or H2S, leading to weakening of equipment like tubing and casing.

Question 3

What is fracture mechanics?

Answer 3

Fracture mechanics is the study of how and why materials crack or fracture, which helps in designing well equipment that can withstand stress without breaking.

Question 4

What is hydrogen sulfide attack?

Answer 4

Hydrogen sulfide (H2S) attack is a type of corrosion that leads to metal cracking, called Sulfide Stress Cracking (SSC) or Hydrogen Induced Cracking (HIC), common in sour gas environments.
