A quick search on AI integration in oil and gas yields various case studies, including Amazon’s Quantiphi, an AI-driven tool used across multiple industries. One blog post highlights Quantiphi's effectiveness in extracting information from lengthy P&IDs. In this report, we aim to achieve similar results by identifying instruments, equipment, and piping using OpenAI’s ChatGPT 4.0.
Documents Generated Using ChatGPT
Some of the documents that can be generated using ChatGPT 4.0 include:
Line List
Equipment List
Instrument List
Equipment Datasheets
Process Flow Diagram (PFD) Summary
Providing ChatGPT with a specific format and required information helps reduce conversation time and increase efficiency. You can create any document you need, as long as you have the appropriate format and the necessary P&ID information. In this report, we focus on creating a Line List using information extracted from a P&ID. Instructions and prompts are detailed in the following sections.
Technology Used by ChatGPT in P&ID Data Extraction
ChatGPT combines deep learning, natural language processing (NLP), and Python integrations to efficiently extract and organize P&ID data:
Transformer Architecture: ChatGPT’s transformer model enables it to understand engineering contexts and patterns in text, allowing accurate identification of piping lines, tags, and equipment.
NLP Capabilities: Built-in NLP techniques help ChatGPT interpret structured prompts and extract specific components from P&IDs, handling technical language effectively.
Python API Integration: Python is used to automate interactions with ChatGPT, enabling users to streamline prompt management, retrieve responses, and format outputs for engineering documentation.
External Document Processing Tools: ChatGPT integrates with tools like PyMuPDF and Tesseract OCR to process PDFs or image-based P&IDs, converting these formats into readable text for extraction.
Through this setup, ChatGPT simplifies data extraction from P&IDs, reducing manual work and enhancing documentation workflows for engineers.
Instructions and Prompts
Below are instructions on how to generate a Line List with routing from a P&ID using ChatGPT.
Initial Prompt Setup:
Copy and enter this prompt into ChatGPT 4.0:
less
Copy code
"You are a process engineer with the following core capabilities:
Extracting and analyzing information from provided P&IDs,
Generating detailed and accurate documents based on the requested format and specifications."
Identifying Specific Elements:
Customize the prompt depending on the required information:
css
Copy code
"Review each page of the provided document thoroughly.
Identify all the [Equipment Name] and their tags associated with the [Process Name].
Once identified, cross-check each entry a couple of times by locating it in the P&ID to ensure accuracy."
Sample prompt for identifying lines in a system:
css
Copy code"Review each page of the provided document thoroughly.
Identify all the piping lines and their tags associated with the system.
Once a line is identified, cross-check it by locating it in the P&ID to ensure accuracy."
Note: Attach the P&ID when entering this prompt.
