Bubbles morphology, frequency and rising velocity in yield stress fluid under downward gas injection
Chemical Engineering Journal Advances, 2023 Mixing in a reactor can be achieved mechanically or by the injection of a gas. This can be done by injecting a gas towards the bottom of the tank. The induced flow recirculation and then the stirring quality depends on the bubbles morphology, rising ...

Impact of organophilic clay on rheological properties of gasoil-based drilling muds
Journal of Petroleum Exploration and Production Technology, 2020 In this study, the impact of VG69 organophilic clay on the rheological properties of gasoil-based drilling muds (invert emulsions) was investigated. The flow curves of gasoil-based drilling muds as a function of the dose of VG69 organophilic clay were ...
