How do we report usage and discharge of drilling fluids to the EEMS database?
Water based mud systems (WBMs): Water based muds (WBMs) containing <5% water-immiscible liquid should be reported as individual component products. Organic phase mud systems: Oil based muds (OBMs), synthetic drilling fluids (SMs) and emulsified water based muds containing >5% v/v water-immiscible liquid should be reported as made-up mud systems i.e. as shipped offshore. This should include any additional whole mud made up offshore. Additives and contingency chemicals put into the mud on the drilling rig should be reported separately.
