The utilization of Malaysian local bentonite as an extender and free water controller in oil-well cement technology

This paper presents the result of experimental studies for Malaysian bentonite from Sabah (Lahad Datu and Tawau areas) application in oil-well cementing as compared to world wide commercially used Wyoming bentonite of USA. Samples were dried, grounded and sieved into particle size of 75μm. The expe...
