... concentration is reached, the carbonate reacts with calcium, resulting in the precipitation of calcium carbonate (CaCO 3 )( Larsen et al., 2008 ). Abstract Addressing sand production in oil and gas wells is a major challenge, and various methods have been devised to tackle it. However, many...

..., under high temperature, pressure, and salinity conditions (Crabtree et al., 1999; Kamal et al., 2018 ). Calcium carbonate scaling presents a particular challenge for scale control, as it is sensitive to pressure and temperature variations ( Blue et al., 2017 ; Cosmo, 2013 a; Du & Amstad, 2019...

... Abstract Inorganic scale is a relevant cause for production losses in offshore operations. In the development of pre-salt fields calcium carbonate crystallization, especially when the flow is submitted to abrupt depressurization, often cause problems in reservoir selectivity and production...

... injection into the annuli. Biomineralizing fluids were then pumped into the well, where they formed crystalline calcium carbonate in the micro annuli. After 1.5 days of treatment, the injection rate dropped by several orders of magnitude. Subsequent monitoring by a state regulator determined surface...

To seal these fractures, which are sometimes a few microns or less, a new form of micro- or nano-sized sealant is required in addition to the conventional calcium carbonate/graphite particle blend. High-pressure, deep wells in Kuwait often experience severe drilling complications across...
