Attributes in Oil & Gas: Deciding "Go" or "Not-Go"

In the complex world of oil and gas, effective decision-making is crucial. Attributes, a key concept in this industry, play a pivotal role in evaluating and classifying assets, operations, and projects. But what exactly are attributes? Simply put, an attribute represents a characteristic or property of an object or system, which is assessed based on whether it meets a specific requirement. This "go" or "not-go" evaluation helps determine whether the object or system is suitable for a particular purpose.

Understanding the "Go or Not-Go" Concept:

Attributes are often defined by binary conditions, allowing for a clear and concise assessment. For example, a well's "production rate" can be an attribute, with a "go" condition being "above 100 barrels per day" and a "not-go" condition being "below 100 barrels per day". This simple categorization helps quickly identify wells that meet production targets and those that fall short.

Applications of Attributes in Oil & Gas:

Attributes are applied across various facets of the oil and gas industry, including:

  • Asset Management: Attributes help categorize wells, reservoirs, pipelines, and other assets based on their characteristics. This assists in efficient planning, optimization, and resource allocation.
  • Drilling & Completion: Attributes can be used to assess the suitability of drilling sites, wellbore designs, and completion techniques, ensuring optimal performance and minimizing risks.
  • Production Optimization: Attributes related to production rate, fluid properties, and well pressure help identify areas for improvement and potential bottlenecks, leading to enhanced production efficiency.
  • Risk Assessment: Attributes can help quantify risks associated with various operations, such as environmental hazards, equipment failures, and safety incidents. This allows for proactive mitigation strategies and improved safety protocols.

Key Benefits of Using Attributes:

  • Standardized Evaluation: Attributes provide a consistent framework for evaluating assets and projects, eliminating subjective interpretations.
  • Data-driven Decision-making: Attributes rely on objective data, enabling informed decisions based on real-world observations and measurements.
  • Improved Efficiency: The clear categorization of "go" or "not-go" simplifies decision-making processes and speeds up operational workflows.
  • Enhanced Risk Management: By identifying critical attributes and their potential failures, companies can proactively address risks and minimize potential losses.

Conclusion:

Attributes are a powerful tool in the oil and gas industry, enabling precise categorization, efficient decision-making, and robust risk management. By understanding and applying this concept, industry professionals can optimize operations, maximize profitability, and ensure long-term success. The "go or not-go" framework provides a clear and concise approach to assessing assets, operations, and projects, driving the industry forward with data-driven insights and strategic foresight.

Exercise: Attribute Analysis

Task: Imagine you are a drilling engineer evaluating a potential drilling site. You need to assess several key attributes to decide if it's a "go" or "not-go" decision.

Attributes:

  • Depth to Reservoir: < 2000 meters - "Go", >= 2000 meters - "Not-Go"
  • Reservoir Pressure: > 2000 psi - "Go", <= 2000 psi - "Not-Go"
  • Production Potential: > 500 barrels per day - "Go", <= 500 barrels per day - "Not-Go"
  • Environmental Risk: Low - "Go", High - "Not-Go"

Data:

  • Depth to Reservoir: 1800 meters
  • Reservoir Pressure: 2500 psi
  • Production Potential: 400 barrels per day
  • Environmental Risk: Low

1. Based on the data, determine the "go" or "not-go" status for each attribute.

2. Based on your analysis, would you recommend drilling at this site? Explain your reasoning.

Exercice Correction

**1. Attribute Analysis:** * **Depth to Reservoir:** "Go" (1800 meters < 2000 meters) * **Reservoir Pressure:** "Go" (2500 psi > 2000 psi) * **Production Potential:** "Not-Go" (400 barrels per day <= 500 barrels per day) * **Environmental Risk:** "Go" (Low risk) **2. Drilling Recommendation:** While the depth, pressure, and environmental risk are favorable, the production potential falls below the target. Therefore, I would recommend a "Not-Go" decision for drilling at this site. The low production potential might not justify the investment and resources needed for drilling. Further investigation and analysis could be conducted to explore alternative solutions, such as optimizing the well design or seeking alternative locations with higher production potential.
