AIM: TO DETERMINE SUITABILITY AND CONSEQUENCES OF REUSING MUD AND RECOVERED OIL FROM THERMAL DESORPTION

The purpose of the project arose from an industry query to determine if used mud and recovered oil could be reused.

R.U.M. Consultancy Ltd was the appointed laboratory for this project. Analyses were carried out to determine potential differences between oil based mud at the start of the drilling section compared to mud at the end of the section and recovered oil compared to virgin oil, which included:

- Changes in polynuclear hydrocarbons (PAH) and single ring aromatic hydrocarbons (BTEX) concentrations in the recovered oil and used mud
- Impact on toxicity of increasing concentrations of PAH and BTEX in oil base mud
- Changes in baseline level of PAH and BTEX
- Changes in flash point of recovered oil
