Desilter Quiz

Instructions: Choose the best answer for each question.

1. What is the primary function of a desilter?

a) To remove large rocks and debris from drilling fluid. b) To separate water from drilling fluid. c) To remove very fine particles, or silt, from drilling fluid. d) To add chemicals to drilling fluid.

Answer

c) To remove very fine particles, or silt, from drilling fluid.

2. How does a desilter work?

a) By using a magnetic field to attract and remove silt. b) By filtering the drilling fluid through a fine mesh screen. c) By using centrifugal force to separate silt from the fluid. d) By chemically reacting with the silt to dissolve it.

Answer

c) By using centrifugal force to separate silt from the fluid.

Desilter Exercise

Problem:

A drilling crew is experiencing problems with their drilling fluid, leading to reduced drilling efficiency and potential equipment damage. Analysis reveals an excessive amount of silt in the fluid. They need to implement a solution to remove this silt.

Task:

  1. Identify the appropriate equipment: What specific equipment can help the drilling crew remove the silt from their drilling fluid?
  2. Explain the reasoning: Why is this equipment the best choice for this situation?
  3. Outline the steps: Briefly describe the process of using this equipment to solve the problem.

Exercice Correction

**1. Identify the appropriate equipment:** A desilter. **2. Explain the reasoning:** Desilters are specifically designed to remove very fine particles like silt from drilling fluid. This is crucial for improving the quality of the fluid and preventing issues caused by excessive solids. **3. Outline the steps:** * The drilling fluid is pumped into the desilter. * The desilter uses centrifugal force to separate the silt from the fluid. * The cleaned fluid is then returned to the drilling operation. * The collected silt can be disposed of or processed further.
