This set of Petroleum Production Operations Multiple Choice Questions & Answers (MCQs) focuses on “Scale Prevention”.
1. A ____ completion is used where the producing formation lacks sufficient consolidation to withstand the friction caused by fluid flow from the formation to the wellbore.
a) Barefoot
b) Dual
c) Barefoot
d) Gravel pack
View Answer
Explanation: A Gravel pack completion is used where the producing formation lacks sufficient consolidation to withstand the friction caused by fluid flow from the formation to the wellbore. The main purpose of the Mechanical Method is to hold the formation of sand in place so basically gravel packs and screens to hold the gravels or simply screens are used for this purpose.
2. Scale inhibitors can’t prevent scaling in oil and gas wells.
a) True
b) False
View Answer
Explanation: The statement is false. The corrected statement is that Scale inhibitors can prevent the scaling process of an oil and gas well. Scale inhibitors are mainly chemicals that are pushed down the well.
3. Bullheading is a constant bottom hole pressure method.
a) True
b) False
View Answer
Explanation: The statement is true. Bullheading is a constant bottom hole pressure method. Bullheading is one of the well control methods that are utilized in some events of the oil and gas industry to control the well.
