Okay, let’s tackle this. So Derek Rupp has a mix of technical skills like Autocad, Pro Engineer, and Solidworks, which are in demand in the oil and gas industry. He also has experience in project management and technical drawing, which are valuable skills. Location is Tulsa, Oklahoma, which is a smaller market. Considering his skills and experience, I’m estimating his hourly rate to be around $125, which is on the lower side of the industry average for a professional with similar skills in the US. Some oil and gas professionals with similar skills can charge $200-$300 per hour, but Derek’s experience and skills suggest a lower rate.
