ANL has developed capabilities to develop novel phosphate cements for deep well applications. ANL approach consists of, 1) using thermodynamics and predicting solubility of range of oxides and minerals and then determining whether a particular material is suitable for formation of cements, 2) using differential thermal and X-ray diffraction analyses to test the suitability, 3) to produce cement at an elevated temperature in air and confirming results of the previous two steps, and then 4) testing the cement in oil well conditions and modifying the process to comply with American Petroleum Institute’s guidelines for pumping cements. In this report, the approach is summarized and with the example of alumina, it is shown that this material may be one most suitable for development of the deep well cement. We recommend that this material be considered for development as phosphate cement for deep wells.
