Branding for NAFTOLCHEM

A friend of mine asked me to create a logo for their company.
Naphtolchem is a company, founded by engineers with vast experience in the oil and gas production area. Naphtolchem offers numerous well stimulation solutions and necessary engineering support.
This is the result. In my head I simplified the word "solution" to a "mixture" and wanted to make things mix together to be in the middle. That's how I came up with the idea and my client loved it at the first glance.
