2.

What is a HpHT well?
- It has nothing to do with drilling
- Higher Part of The Well
- A well with high Temperatures and Pressure
- Well with high production and long lifetime
Correct Answer

A. A well with high Temperatures and Pressure

Explanation

An HPHT well refers to a well that operates under high temperatures and pressures. This means that the well is subjected to extreme conditions, which can pose various challenges during drilling and production. High temperatures and pressures can affect the integrity of the wellbore and require specialized equipment and techniques to ensure safe and efficient operations.

3.

What can a Kick lead to?
- More Production
- A New Reservoir
- A Blow Out
- Lower Production
Correct Answer

A. A Blow Out

Explanation

A kick in the context of oil drilling refers to the influx of formation fluids (such as oil or gas) into the wellbore. This can occur when the pressure from the formation exceeds the pressure exerted by the drilling mud. A blowout, on the other hand, is a sudden and uncontrolled release of formation fluids from the well. Therefore, a kick can potentially lead to a blowout, making it the correct answer.

4.

Where is the BOP placed?
- In the Reservoir
- Together with the BHA
- Top of the well
- In the CMC
Correct Answer

A. Top of the well

Explanation

The BOP (Blowout Preventer) is placed at the top of the well. This is a safety device used in drilling operations to prevent the uncontrolled release of oil or gas from the well. By placing the BOP at the top of the well, it can quickly and effectively shut off the flow of fluids in case of an emergency or blowout. This location allows for easy access and control of the BOP, ensuring the safety of the well and the surrounding environment.

5.

What is tripping?
- Running Pipe out of hole
- Drilling Operation
- Other word used for fishing operations
Correct Answer

A. Running Pipe out of hole

Explanation

Tripping refers to the process of running the pipe out of the hole during drilling operations. This is done to remove the drill string, which consists of the drill pipe and other tools, from the wellbore. Tripping is an essential part of drilling as it allows for various operations such as changing the drill bit, adding or removing pipe sections, and conducting maintenance or repairs. It is a crucial step in the drilling process and is necessary to ensure the smooth and efficient operation of the well.

The surface casing is used to:
- isolate freshwater zones so that they are not contaminated during drilling and completion
- Connect riser and well head
- To enhance production of hydrocarbons
- Kill well when needed
Correct Answer

A. isolate freshwater zones so that they are not contaminated during drilling and completion

Explanation

The surface casing is used to isolate freshwater zones so that they are not contaminated during drilling and completion. This is important to prevent any contamination of the freshwater sources, ensuring their safety and availability for human consumption and other purposes. By creating a barrier with the surface casing, any potential pollutants or fluids used during drilling and completion processes are prevented from entering the freshwater zones, thus preserving their integrity.

How deep is deep water today?
- 100 ft
- 1000 ft
- 4000 +++ ft
- 200 000
Correct Answer

A. 4000 +++ ft
8.

This equipment is a part of the circulation system on a rig. But what is this?
- Offshore Printer
- VSM Multi-Sizer Shaker
- Topdrive
- Catwalk Machine
Correct Answer

A. VSM Multi-Sizer Shaker

Explanation

The VSM Multi-Sizer Shaker is a piece of equipment that is part of the circulation system on a rig. It is used to separate and remove solid particles from drilling fluid, ensuring that the fluid can be reused and maintaining the efficiency of the drilling process.

ROP is an important factor when drilling, what does it mean?
- Rate of Production
- Rate of Penetration
- Rate of Pressure
- Remote Operated Platform
Correct Answer

A. Rate of Penetration

Explanation

ROP stands for Rate of Penetration, which is a crucial factor in drilling operations. It refers to the speed at which a drill bit penetrates the rock or formation being drilled. The higher the ROP, the faster the drilling process, which is desirable as it saves time and costs. ROP depends on various factors such as the type of rock, drilling equipment, weight on bit, and drilling fluid properties. By monitoring and optimizing the ROP, drilling engineers can improve drilling efficiency and maximize productivity.

What is break even?
- When you produce the same amount of oil and gas
- The price of oil/gas where a project is economically positiv
- The connection place between pipe
- Area where well meets reservoir
Correct Answer

A. The price of oil/gas where a project is economically positiv

Explanation

The correct answer is "The price of oil/gas where a project is economically positive." This refers to the point at which the revenue generated from selling oil or gas equals the total costs incurred in producing it. At this point, there is no profit or loss, and the project becomes financially viable. It is an important concept in determining the profitability and sustainability of oil and gas projects.

Where do we typically find the HpHT wells?
- Offshore Africa
- Oilsands in Canada
- Onshore Shales in America
Correct Answer

A. Offshore Africa

Explanation

HPHT (High Pressure High Temperature) wells are typically found offshore Africa. This region is known for its vast offshore oil and gas reserves, and many of these reserves are located in HPHT environments. HPHT wells are characterized by extreme pressures and temperatures, often exceeding 15,000 psi and 350 degrees Fahrenheit. Offshore Africa offers the necessary geological conditions and infrastructure to safely drill and operate HPHT wells, making it a prominent location for such operations.
