SC DrillTech ROC™ — Retention-on-Cuttings Toolkit
Turn one retort reading into a number you can defend.ROC™ takes the gravimetric weights from a single cuttings sample and back-calculates exactly how much fluid is leaving the rig on the solids — then audits the mass balance and checks it against the discharge limit automatically. When someone asks "how do you know we're losing that much?", you have the method, the math and the paper trail.WHAT YOU GET ROC Calculator — retention by wet weight and dry weight from a simple gravimetric (retort) sample.
