The Effect of Adding Palm Oil Fly Ash to the Development of Strength on Oilwell Cement

Abstract

Calcarcous and argillaceous materials are raw materials used in making oilwell cement G with their main chemical compound consists of tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium aluminoferrite. Pozzolanic reactions existed in some of the fly ashes when added with water helps in improving the cement strength when they are added to the cement. Therefore, palm oil fly ash, a locally waste materials is chosen for the study. Chemical analysis according to ASTM C 115 were carried out to determine the composition. Compressive strength tests were carried out according to American Petroleum Institute Specification 10 and were conducted at simulated reservoir condition. The analysis and the results proved that palm oil fly ash is a pozzolan material and can be used to improve the strength development of the oilwell cement.
