Descriptive vs. Prescriptive: Navigating the Language of Oil & Gas Instructions

In the intricate world of oil and gas operations, precision in communication is paramount. This extends not just to the technical details of procedures, but also to the very language used to convey them. Two key terms, "descriptive" and "prescriptive," play a crucial role in this communication, dictating the level of detail and clarity required for specific instructions.

Descriptive Instructions: Painting the Picture

Imagine a painter describing the nuances of a landscape – the colors, textures, and overall mood. Descriptive instructions in oil and gas operate similarly, focusing on providing a broad overview of a process or task. They emphasize the "what" and the "why," offering insights into the goals and context without delving into the granular "how."

Here's what descriptive instructions typically provide:

• Purpose and objective: The overall aim of the procedure, highlighting the desired outcome.
• Context and background: Information surrounding the task, including its relevance and potential implications.
• General principles and guidelines: Broad overarching principles and guidelines to be followed, offering a framework for decision-making.

Examples of Descriptive Instructions:

• "During well stimulation, ensure optimal fluid distribution to maximize reservoir contact."
• "Conduct thorough inspections of pipelines and equipment to prevent potential leaks and safety hazards."
• "When dealing with hazardous materials, prioritize safety procedures and adhere to strict handling protocols."

Prescriptive Instructions: A Step-by-Step Guide

In contrast, prescriptive instructions function like a recipe, providing a detailed, step-by-step guide for completing a task. They focus on the "how," offering precise, actionable steps to ensure consistent results.

Here's what prescriptive instructions typically include:

• Specific procedures: Detailed step-by-step instructions for each action.
• Quantifiable measurements: Precise values for quantities, pressures, and other relevant variables.
• Equipment and materials: A complete list of necessary tools and materials.
• Safety protocols: Explicit safety guidelines and emergency procedures.

Examples of Prescriptive Instructions:

• "Connect the pressure gauge to the wellhead, ensuring a tight seal using a wrench with a torque setting of 100 ft-lbs."
• "Open the valve slowly until the pressure reaches 500 psi, then monitor the flow rate using the digital meter."
• "In case of a gas leak, activate the emergency shut-off valve and evacuate the area immediately."

Choosing the Right Approach:

The choice between descriptive and prescriptive instructions depends heavily on the specific context and the audience.

• Descriptive instructions are ideal for:
  • Training new personnel.
  • Providing general guidance.
  • Setting the stage for more detailed procedures.
• Prescriptive instructions are best suited for:
  • Executing specific tasks with precision.
  • Ensuring consistency and compliance.
  • Providing clear guidance for complex procedures.

The Importance of Clarity and Consistency:

Regardless of the level of detail chosen, clarity and consistency are vital. Ambiguity can lead to errors, misinterpretations, and even accidents. In the high-stakes world of oil and gas, clear communication is not just a good practice, it's a crucial safety measure.

By understanding the difference between descriptive and prescriptive instructions, industry professionals can ensure that information is communicated effectively, minimizing confusion and promoting safety and efficiency throughout the entire process.
