This study shows how artificial intelligence helps fix maintenance issues in oil and gas factories, tackling problems like frequent breakdowns, wasted time, or rising repair bills. Instead of guessing when machines fail, it uses smart systems - like random forest models and combined learning methods - that learn from past records, live signals from IoT gadgets, plus advice from makers to plan fixes just in time. In harsh areas where gear such as spinning pumps or heat changers runs nonstop under
