This set of Petroleum Production Operations online quiz focuses on “Introduction to Scale Deposition, Removal and Prevention”.
1. The direct cause of scaling is sometimes pressured drops.
a) True
b) False
View Answer
Explanation: The statement is true. The direct cause of scaling is sometimes pressured drops. Scales are not desirable. If the skin factor is negative then it is favorable otherwise it is not desirable as it decreases the well productivity.
2. One of the primary factors because of which scaling takes is the mingling of compatibility of the two different fluids.
a) True
b) False
View Answer
Explanation: The statement is false. The corrected statement is that “one of the primary factors because of which scaling takes is the mingling of incompatibility of the two different fluids”. So the fluid used in the well should be well compatible.
3. Which of the following is correct regarding the oilfield scale Calcite?
a) One of the many forms of the barium sulfate mineral
b) Oil additives
c) A scale formed from a supersaturated solution
d) Usually formed as an evaporite
View Answer
Explanation: Calcium carbonate, CaCO3. It may be rock (limestone) or a scale formed from supersaturated solution at the site of a chemical or physical upset. Carbonates are more heterogeneous than sandstone rock.
4. Which of the following is correct regarding the oilfield scale Barite?
a) One form of the barium sulfate mineral
b) Oil additives
c) Usually formed as an evaporite
d) A scale formed from a supersaturated solution
View Answer
Explanation: One of the many forms of the barium sulfate mineral. The BaSO4 material is used in drilling mud as a weighting agent. It can produce a slurry of over 20 lb/gal in water. It increases the weight of the drilling mud.
5. Which of the following is correct regarding the oilfield scale Anhydrite?
a) Oil additives
b) Usually formed as an evaporite
c) One form of the barium sulfate mineral
d) A scale formed from the supersaturated solution
View Answer
Explanation: Anhydrite is CaSO4 formation. It is usually generated as an evaporite from a drying lake of trapped seawater. In the sandstone scale, in the log interpretation or formation evaluation anhydrite shows negative porosity.
