| Summary: | The main objectives of this research are: (1) to find an alternative for oil well cementing system by using Microwave Incinerated Rice Husk Ash (MIRHA) geopolymer, (2) improve strength of oil well cementing system (3) introduce a green technology of oil well cementing system (4) make use of the fly ash and rice husk ash produced in industries. MIRHA was found to provide a competitive strength compared to the Portland cement in other application than oil well cementing. Therefore in this research, MIRHA is used to produce suitable geopolymer cement that can be used for oil well cementing system. Six models of geopolymer cement using MIRHA have been developed throughout this research in order to find the most ideal to be used in oil well cementing system in terms of its compressive strength. The ideal geopolymer cement in this research should provide competitive strength as given by the API cement classes used in oil well cementing system. Oil wells cement analysis, slurry preparation and compressive strength factors have been taken into consideration throughout the development of this research to ensure its successfulness.
Geopolymer sample B in this research has shown impressive compressive strength for 24hours curing at 80„aF which is 2085.64 psi. This is 76.01% improvement of compressive strength compared to API cement class G and 95.91% improvement of compressive strength compared to API cement class H with the same curing time and temperature. Other than that, geopolymer samples A, C and D also has shown improvement in compressive strength. Therefore, we can say that MIRHA geopolymer have better compressive strength than API cement class G and H and thus, MIRHA geopolymer can replace API cement classes G and H in oil well cementing system as basic cement from surface to 8000ft of depth. All of the research¡¦s objectives were successfully achieved. Detailed results can be found throughout this paper. |
