Some Interview Question Mohd Zeeshan Khan

Explain what is well logging? A well log is used for graphical representation of any drilling condition or subsurface features that come across while drilling, which is used for the evaluation of the well.

List out the methods used for well test analyses? Various methods for well test analyses are Pressure drawdown tests Pressure build up tests Type curve analysis Pulse tests and Interference Drill stem and wireline formation Gas well tests

Mention what are the different types of well logging? Resistivity logs Spontaneous potential logs Gamma ray logs Neutron logs sonic porosity logs

What is the importance of drilling muds? The drilling muds are used for • Lubrication purpose and for cooling of the drill bit and pipe • It removes the cuttings that come from the bottom of the oil well • Prevent blowouts by acting as a sealant

What is the drill-stem testing? Lowering a device into the drill hole to measure the pressures, it will reveal whether reservoir rock has been reached.

What is Proppant and what is the use of it? A proppant is a solid material, which is treated with sand or ceramic materials. It is used to keep the induced hydraulic fracture open.

Some Interview Question Mohd Zeeshan Khan Explain the term desander and desilter? Desander is a centrifugal device used for removing sand from drilling the fluid to avert the abrasion of the pumps. While Desilter is a centrifugal device used to remove the slit or very fine particles.

Explain what is wellbore storage? When the oil well is shut-in, there is continue flow of fluid into the wellbore. This flow of fluid is referred as wellbore storage.

Explain what is a blowout preventer? Blowout preventer is installed on the top of the well and is used to control the back pressure produced by oil during the drilling process.

Explain what is annular blowout preventer? Annular blowout preventer is usually a large valve, installed above the ram preventers, it forms a protective seal in the annular space between the pipes and well bore. It seals the annulus between the Kelly, drill collar and drill pipe.

What is API gravity? API means American Petroleum Institute; it is the main association for the oil and natural gas industry in U.S. The API denotes about 400 corporations in the petroleum industry and helps to set the standard for production, refinement and distribution of petroleum product.

How API is calculated? API is nothing but the ratio of its density compare to other substance like water to check the standard of the oil. The formula to check API is API gravity = (141.5/ Specific Gravity) – 131.5

What are your career goals?  Since I am a fresh graduate, I believe in the importance of growth and skills enhancement.  I want to be really skillful and fine educated engineer with pretty good practical skills.

Some Interview Question Mohd Zeeshan Khan

How do you handle stressful situations?  Based from my experience I just being calm.

Where do you see yourself in 5 years?  I see myself having taken part in many projects and have experienced many ups and downs. I see myself having been promoted 3 times and on progress to become the chief reservoir engineer.  I hope to see myself finishing my master and getting more experience in my field of study.  I see myself as a drilling engineer specializing in well control and having kept my crews as safe as possible.  I see myself having extensive knowledge of the operations of this company and that I have made a significant impact in the company's goals.

What is the drill-stem testing? A drill stem test (DST) is a procedure for isolating and testing the pressure, permeability and productive capacity of a geological formation during the drilling of a well. The test is an important measurement of pressure behavior at the drill stem and is a valuable way of obtaining information on the formation fluid and establishing whether a well has found a commercial hydrocarbon.

Do you work well under pressure? Uncomfortably but work through it with excellent time management skills.

What is well logging? A well log is used for graphical representation of any drilling condition or subsurface features that come across while drilling, which is used for the evaluation of the well. What is your greatest weakness? And your greatest strength? Oral communication; written communication.

Why are you the best candidate for us? Experience and Impeccable career record.
