Chemical Engineering In the future I would like to become a chemical engineer. I really enjoy chemistry and hands on work “Chemical engineering is the application of chemistry to large scale industrial systems.” (Chemical engineering). I enjoy helping build different things like skateboards‚ ramps and‚ fixing parts on different things. When I took the sixteen personality quiz it said I was a virtuoso. The virtuoso likes hands on work and exploring ideas which I think fits my personality perfectly

Reservoir engineering is a branch of petroleum engineering that applies scientific principles to the drainage problems arising during the development and production of oil and gas reservoirs so as to obtain a high economic recovery. The working tools of the reservoir engineer are subsurface geology‚ applied mathematics‚ and the basic laws of physics and chemistry governing the behavior of liquid and vapor phases of crude oil‚ natural gas‚ and water in reservoir rock. Of particular interest to reservoir
