  • CEMENTING - cu

    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.

  • yield - Schlumberger Oilfield Glossary

    A term used to specify the quality of a clay according to the number of barrels of 30-cp viscosity mud that one ton of the clay would produce. Although seldom used today, clays were classified as high-, medium- or low-yield bentonites. A "good" bentonite produced at least 85 bbl of mud per ton. High-yield clays produced 30 to 50 bbl/ton, and low-yield clays produced 15 to 30 bbl/ton.
