The situations in the field are various, which is a challenge in both design and logistics for drilling mud treatment and management. After the core treating process such as solid-liquid separation, it is essential to combine some different operational modules to fulfill the rapid and full handling. The following section will briefly discuss the on-site and off-site treatment/management based on chemical separation according to previous experience.
Mineralogy of Cuttings
Drill cuttings are particles of crushed rock produced by the grinding action of the drill bit as it penetrates into the earth. Drill cuttings range in size from clay-sized particles (~ 2 μm) to coarse gravel (> 30 mm) and have an angular configuration. Their chemistry and mineralogy reflect that of the sedimentary strata being penetrated by the drill.
