is hoped that the benefits of the API system of classification and specification will be realized and that the system will find wide acceptance and use by all who are concerned with the cementing of oil and gas wells, Portland cement is a hydraulic product made by burning and grinding a mixture of calcareous and argillaceous materials, such as limestone and clay, limestone and shale, limestone and marl, chalk, and clay, or limestone and iron blast furnace slag Although portland cement is primarily a construction product, it is usedextensively also in oil-well cementing operations, Test procedures and specifications for the performance of various types of portland cement in construction work ale maintained by the American Society for Testing Materials (ASTM) ASTM tests are made-quate for determining the performance of cements in wells because they are made under conditions dissimilar to those encountered in oil-well cementing operations The literature reveals that this fact has been recognized since the early use of portland cements in wells 1. /MK /F 4 22 0 obj /P 300 0 R /Type /Annot 237 0 obj /Rect [111.121 359.222 407.817 377.272] endobj /Type /Annot << << TECHNICAL DATA

needed for various well conditions, The API specification discussed in this paper contains a set of physical and chemical requirements constituted specifically to cover those properties needed in the cementing of oil and gas wells It includes also a system of classifying and identifying portland cement In terms related to well-cementing operations The system provides for seven classes of portland
