Produced Water: 2018 #74

Problem 74: The following statement is most FALSE: 

(A) Chlorine is the most common chemical biocide used in oilfield surface water-injection systems.
(B) Moderate pressure seawater service most commonly uses FRP though sunlight can degrade...
(C) A solid/liquid hydrocyclone cannot remove both primary & secondary solids from surface water.
(D) Surface-water injection is an attractive option as...very little environmental impact or concern. 

Produced water has many potential questions; the Guidebook has a good summary. My recommendation: take an hour and read the referenced HS section with an eye to areas that seem non-intuitive or are unfamiliar to you.

For more information on the above selection options such as biocide, FRP, and water injection, see HS3 P168, P179, P163, and P159 and help clarify this fairly confusing subject.

  1. I did find (c) in GB 7PRD13. Why C is the most false one? Any mistake in GB?

    1. I don't get you; I just looked in the Guidebook 7 PRD 13 (V3) and it says "A solid/liquid hydrocyclone CAN remove both primary & secondary solids from surface water."

      And if you look at the references listed in the GB you can see this is merely a quote from HS P163.

  2. Can you please post the solution to #73? I don't see the solution on 13 Res 11. Thanks.
