This set of Petroleum Production Operations Multiple Choice Questions & Answers (MCQs) focuses on “Characteristics of Surfactants”.
1. A surfactant has two parts in it.
a) True
b) False
View Answer
Explanation: The statement is true. A surfactant has two parts in it. One part is soluble in oil and another part is soluble in water. The molecule thus is partially soluble in both water and oil. It has both good and bad effects.
2. What do you mean by a surfactant has a stronger affinity for oil?
a) Oil wet
b) Water soluble
c) Oil soluble
d) Water Wet
View Answer
Explanation: The surfactant that has a stronger affinity for oil is also classified as Oil soluble. A surfactant has two parts in it. One part is soluble in oil and another part is soluble in water. The molecule is thus partially soluble in both water and oil.
3. What do you mean by a surfactant has a stronger affinity for water?
a) Oil wet
b) Water soluble
c) Oil soluble
d) Water Wet
View Answer
Explanation: The surfactant that has a stronger affinity for water is also classified as Water soluble. A surfactant has two parts in it. One part is soluble in oil and another part is soluble in water. The molecule thus is partially soluble in both water and oil.
4. Surfactants can alter the wettability of the reservoir rock.
a) True
b) False
View Answer
Explanation: The statement is true. A surfactant has two parts in it. One part is soluble in oil and another part is soluble in water. Surfactants can alter the wettability of the reservoir rock.
5. Consider the following as a surfactant molecule. What is the name of the part A?
a) Water-soluble Group
b) Oil soluble Group
c) Both Oil and Water-soluble Group
d) Both are non- soluble Group
View Answer
Explanation: Part A of the surfactant molecule is known as the Water-soluble Group. The part B of the surfactant molecule is known as Oil soluble Group. The molecule is thus partially soluble in both water and oil.
