Calcareous and argillaceous materials are raw materials used in making ordinary portland cement and portland cement class G with their main chemical compound consist of tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium aluminoferrite. Currently, the class G cement used for the oil and gas wells cementing operations is imported from other countries. Therefore, suitability studies of our locally produced ordinary portland cement and blended cement were carried out to overcome this matter. To justify their ability to be used in the oil and gas wells cementing operations, they must comply with the standards set by the American Petroleum Institute (API) interms of their chemistry and physical properties requirements. Chemical analysis according to ASTM C115 were carried out to determine the composition. Compressive strength, free water, thickening time and fluid loss were carried out according to API Specification 10 and were conducted at simulated reservoir condition. Generally, locally produced cement proved chemically and physically to comply within the API Specification and has the possibility to be used for the oil and gas wells cementing operations.
