This set of Petroleum Production Operations Multiple Choice Questions & Answers (MCQs) focuses on “Carbonate Acidizing”.
1. The objective of acidizing limestone and dolomite wells is to remove damage near the wellbore.
a) True
b) False
View Answer
Explanation: The statement is true. Acidizing is a type of well stimulation to increase the flow by changing the flow characteristics or the environment of the porous media. It minimizes the formation damage near the wellbore in the limestone and dolomite.
2. What is the full form of EGMBE?
a) Ethylene Glue Monobutyl Ether
b) Ether Glycol Monobutyl Ethylene
c) Ethylene Glycol Monobutyl Ether
d) Ether Glue Monobutyl Ethylene
View Answer
Explanation: The full form of EGMBE is Ethylene Glycol Monobutyl Ether. This is used in the After Flush stage. This is mainly used to make the surface water wet and to displace away from the wellbore.
3. Which of the following is incorrect regarding the chelating agent?
a) Alternative to HCl in deep reservoirs
b) Used to remove scales
c) No need for iron control agents
d) Need for corrosion inhibitors at medium and high pH
View Answer
Explanation: The incorrect statement among the mentioned statements is “Need for corrosion inhibitors at medium and high pH”. The corrected statement is “No need for corrosion inhibitors at medium and high pH”. While using the chelating agent there is no need for iron control agents.
4. Suspending materials are not beneficial because insoluble fines are always released by acidizing.
a) True
b) False
View Answer
Explanation: The statement is false. The corrected statement is suspending materials are beneficial because insoluble fines are always released by acidizing. Suspending agents are used in the oil and gas industries are the substances using which the solid substances can be held in suspension.
5. Which of the following statement is not correct regarding carbonate acidizing?
a) The effectiveness of the fracture depends only on conductivity
b) Chelating agents are used to removing scales
c) A large number of fines during fracturing may not increase the production rate
d) The full form of EGMBE is Ethylene Glycol Monobutyl Ether
View Answer
Explanation: The incorrect statement among the mentioned statements is “The effectiveness of the fracture depends only on conductivity”. The corrected statement is “The effectiveness of the fracture depends on conductivity and penetration”. Dynamic ething tests can be an effective means for calculating the probability of an increase in production.
