FLOCCULATED WATER systems are most often used to drill upper hole sections. The main advantages of flocculated water include:
When drilling with flocculated water, polymers are added to the circulating system at surface, usually near the shale shaker. These polymers become attracted to drilled solids, causing them to aggregate. The increased effective diameter of the aggregates promotes rapid settling. The objective of this system is to supply completely clear water to the pump suction.
