| description | The stability of shales rich in clay is deeply affected by its complex physical and chemical interactions with drilling fluids. Thus, these rocks with a high content of clay have shown significant changes, such as swelling or expanding, when placed in contact with aqueous fluids due to the adsorption of polar molecules of water or hydrated ions dissolved inside . These changes may cause the collapse of the rock during the drilling with water-based drilling fluids. For a better understanding of the phenomenon of interaction between the rock and the drilling fluid, this study aims to analyze reactivity of shales from the Bacia do Araripe through its characterization. In order to do so, the shales were characterized by CEC, XRF, XRD and Foster swelling. The results indicated that the shales showed significant values of CEC, FRX composition close to that of smectite, and XRD pattern with characteristic peaks of smectite. Regarding the Foster swelling, the shale that presented the highest CEC (F-IP) also presented the highest value of swelling, indicating that the CEC can be applied as an indicative parameter of the reactivity. |
