Strip Over: A Critical Technique in Oil & Gas Production

Strip over is a crucial term in oil and gas operations, encompassing two distinct yet related practices:

1. Strip Over as a Recovery Method:

In this context, strip over refers to a secondary recovery method aimed at maximizing oil production from existing wells. This technique involves injecting a fluid, typically water or gas, into the reservoir to push remaining oil towards the wellbore. This process is often employed after primary recovery methods, like pumping, have become less effective.

Here's how it works:

  • Injection: Water or gas is injected into the formation through an injection well located strategically near the producing well.
  • Displacement: The injected fluid displaces the remaining oil in the reservoir, pushing it towards the producing well.
  • Extraction: The oil, now mobilized by the injected fluid, flows through the producing well and is extracted for processing.

Benefits of Strip Over:

  • Enhanced Oil Recovery (EOR): Strip over significantly increases oil recovery rates, leading to more efficient use of the reservoir.
  • Increased Productivity: By mobilizing trapped oil, the method boosts the producing well's output.
  • Reservoir Management: Strip over helps maintain reservoir pressure, preventing premature decline in production.

2. Strip Over as a Wire Installation Method:

Less commonly, strip over also refers to a wire installation method utilized in the oil and gas industry. This involves using pipe to guide and protect wires during their installation, primarily in situations where wires need to be laid along long distances or through challenging terrain.

Here's how it works:

  • Pipe Preparation: A dedicated pipe is prepared to serve as a conduit for the wires.
  • Wire Installation: The wires are carefully inserted into the prepared pipe, providing them with a protective barrier.
  • Installation: The pipe with the installed wires is then laid along the desired route, protecting the wires from damage.

Benefits of Strip Over for Wire Installation:

  • Protection: The pipe shields the wires from harsh environmental conditions and physical damage.
  • Durability: The method ensures the longevity and reliability of the wire installation.
  • Ease of Installation: Utilizing pipe simplifies the installation process, making it efficient and less labor-intensive.

In summary:

Strip over is a versatile term with two distinct applications in the oil and gas industry. Whether it's used to maximize oil recovery through injection or to protect critical wiring, it plays a vital role in ensuring the efficient and safe operation of oil and gas facilities.

Incorrect. Strip over helps in managing reservoir pressure and optimizing oil extraction.

2. In the context of oil recovery, what is injected into the reservoir during the "Strip Over" process?

a) Chemicals

Answer

Incorrect. While chemicals are sometimes used in enhanced oil recovery, they are not the primary fluid injected in strip over.

b) Water or Gas

Answer

Correct. Water or gas are typically used to displace the remaining oil in the reservoir.

c) Oil

Answer

Incorrect. Oil is what is being extracted, not injected.

d) Heat

Answer

Incorrect. While heat can be used in some EOR techniques, it's not the primary method in strip over.

3. Which of the following is NOT a benefit of using "Strip Over" for wire installation?

a) Protection from environmental factors

Answer

Incorrect. The pipe acts as a shield against environmental damage.

b) Increased installation time

Answer

Correct. Strip over simplifies installation, making it faster and more efficient.

c) Durability of the wire installation

Answer

Incorrect. The pipe enhances the longevity and reliability of the wiring.

d) Ease of installation

Answer

Incorrect. The use of pipe makes the installation process simpler and less labor-intensive.

4. What is the primary role of the pipe in the "Strip Over" method for wire installation?

a) To increase the conductivity of the wires

Answer

Incorrect. The pipe's role is to protect the wires, not enhance their conductivity.

b) To provide structural support for the wires

Answer

Incorrect. While the pipe provides some support, its main function is protection.

c) To act as a conduit for the wires

Answer

Correct. The pipe guides and protects the wires as they are installed.

d) To amplify the signal carried by the wires

Answer

Incorrect. The pipe's role is purely mechanical, not related to signal amplification.

5. The "Strip Over" method for oil recovery is primarily used:

a) As a primary recovery method

Answer

Incorrect. Strip over is a secondary recovery method, employed after primary methods become less effective.

b) As a tertiary recovery method

Answer

Incorrect. Strip over is considered a secondary recovery method.

c) As a secondary recovery method

Answer

Correct. Strip over is a secondary recovery method designed to increase oil recovery after primary methods.

d) For exploring new oil deposits

Answer

Incorrect. Strip over is used to maximize recovery from existing wells, not for exploration.

Exercice Correction

Advantages:

  • Enhanced Oil Recovery (EOR): Strip over significantly increases oil recovery rates, potentially extending the life of the oil field and maximizing resource extraction.
  • Increased Productivity: By mobilizing trapped oil, the method boosts the producing well's output, leading to higher revenue.
  • Reservoir Management: Strip over helps maintain reservoir pressure, preventing premature decline in production and improving overall field management.

Challenges:

  • Cost of implementation: Setting up the necessary infrastructure for injection wells, monitoring, and equipment can be costly.
  • Injection fluid availability: Ensuring a continuous and reliable source of water or gas for injection may be challenging.
  • Environmental concerns: The potential for groundwater contamination or land subsidence must be carefully considered and mitigated.
