This set of Petroleum Production Operations Multiple Choice Questions & Answers (MCQs) focuses on “Hydraulic Fracturing – Frac Job Design”.
1. Which of the following is correct regarding the Disinfectants?
a) Known as gelation chemicals
b) Prevent a build-up of minerals in the inner wall
c) Used to lower the surface tension
d) Used to limit the growth of microbes
View Answer
Explanation: The disinfectant offers complete microbiological sterilization. Some Disinfectants kill several types of microorganisms. Disinfectants used in the well additives kill more germs than sanitizers.
2. Which of the following is correct regarding the Surfactants?
a) Prevent a build-up of minerals in the inner wall
b) Known as gelation chemicals
c) Used to lower the surface tension
d) Used to limit the growth of microbes
View Answer
Explanation: The Surfactants are compounds that lower the surface tension (or interfacial tension). It can alter the wettability of the rock surface. But engineers have to design the surfactant in a manner that it makes the surface water wet.
3. Which of the following is correct regarding the Thickeners?
a) Prevent a build-up of minerals in the inner wall
b) Known as gelation chemicals
c) Used to lower the surface tension
d) Used to limit the growth of microbes
View Answer
Explanation: A thickening agent that also known as a thickener it is a substance that can increase the viscosity of a liquid without too many changes in its other properties. It is used in the oil and gas industry for special treatment of the well.
4. Which of the following is correct regarding the Scale inhibitors?
a) Prevent a build-up of minerals in the inner wall
b) Known as gelation chemicals
c) Used to lower the surface tension
d) Used to limit the growth of microbes
View Answer
Explanation: Scale inhibitors are the type of chemicals that prevent the build-up of minerals in the inner wall. They inhibit the scaling or the process of deposition of scales. Scale can reduce productivity significantly in oil and gas wells.
5. Which of the following is correct regarding the HCl?
a) Used at some sites to reduce the pressure when shale is cracked first
b) Known as gelation chemicals
c) Used to lower the surface tension
d) Used to limit the growth of microbes
View Answer
Explanation: The correct statement regarding the HCl i.e. Hydrochloric acid is that it is used at some sites to reduce the pressure when shale is cracked first. HCl is acidic in nature and it has low pH.
