# Petroleum Production Operations Questions and Answers – Mechanical Methods of Sand Control

This set of Petroleum Production Operations Multiple Choice Questions & Answers (MCQs) focuses on “Mechanical Methods of Sand Control”.

1. What is the mechanical method of sand control?
a) Use of resin
b) Use of chemical
c) Use of Gravel or Screen
d) Use of special fluid

Explanation: The main purpose of the Mechanical Method is to hold the formation sand in place so basically gravel packs and screens to hold the gravels or simply screens are used for this purpose.

2. Sidewall cores are good for formation sand size analysis.
a) True
b) False

Explanation: The statement is true. Sidewall cores are good for formation sand size analysis. In the development Design criteria, formation sand size analysis is the very first stage for a better understanding of the size of the sand.

3. Sieve analysis provides ¬grain size distribution on______ basis.
a) Percentage
b) Number
c) Percentile
d) Production

Explanation: Sieve analysis provides ¬grain size distribution on a Percentile basis. Sand grain size distribution varies through a particular sand body and certainly from one genetic zone to another.

4. A uniformity coefficient is determined by comparing the 40 percentile with 90 percentile.
a) True
b) False

Explanation: The statement is true. A uniformity coefficient is determined by comparing the 40 percentile with 90 percentile. The formula of the uniformity coefficient is C= D40/D90.

5. If the uniformity coefficient is less than 3 then what does it signify?
a) Sand is uniform and is described by D10 size
b) Sand is non-uniform and is described by D40 size
c) Sand is very non- uniform and is described by D70 size
d) Sand is uniform and is described by D40 size

Explanation: A uniformity coefficient is determined by comparing the 40 percentile with 90 percentile. When the uniformity coefficient is less than 3 then it signifies Sand is uniform and is described by D10 size.
