10 Questions
What factor is the risk of failure related to in cement systems?
Ratio of cement tensile strength to Young’s modulus
How does the usage of flexible particles like rubber or thermoplastics affect cement flexibility?
Improves flexibility
Which type of gas migration occurs before the cement has set?
Short-term gas migration
What can uncontrolled gas migration during cementing lead to?
Risk to equipment and personnel
What is the best way to prevent long-term problems related to gas migration?
Properly addressing gas migration in the initial design
What phenomenon is gas migration during cementing referred to as?
Immediate gas migration
Which zones should gas migration prevention be particularly considered for?
Zones with pore pressure greater than 13 ppg
What can the cost of remediating a gas migration problem far exceed?
Costs of active prevention
How can foamed cement enhance flexibility?
By showing improved flexibility
What does the ratio of cement tensile strength to Young's modulus indicate about the cement's resistance to failure?
Higher ratio means less resistance to failure
