The usual water cement ratio is 45% (5.2 gal/sack) of dry cement; 500 gal per cementing unit should be provided for priming, testing, and cleaning up. An additional 5130 gal should be provided as a minimum safety margin. Rate of water supply should be based on the rate of mixing cement: usually this is 5-6 bbl/min. for each pumping unit on the job.
