“…In unconventional oil/gas extraction, Ba, both in produced water and as barite scale, is a known problem [1][2][3][4][5] . Over the decades research regarding Ba in conventional and unconventional systems have focused on mitigation of barite scale [6][7][8][9][10][11] . In the case of shale, scale damage is particularly deleterious because it occurs in pore spaces and microfractures within the shale matrix 12 , permanently destroying production.…”

“…which occurs at the beginning of fluid injection was not investigated 13 . Other researchers have also tested the leachability of Ba from shale samples and found that a significant amount of Ba in the rock is stable unless extremely harsh chemical extractants not found in unconventional extraction are used 9,14 . Besides Ba release from the general shale matrix (small barite grains, associated with pyrite, bound to clays, etc.…”

“…A laminar flow is considered, as the imposed velocity value is low. As the temperature dependency of the kinetic coefficient k r is not available in the literature, it is taken as constant . The saturation concentration

Modelling of solid formation by heterogeneous reactions through a multicomponent transport model of diluted ionic species: Simulation of barite fouling in a geothermal heat exchanger

et al. 2020

A general model is proposed in order to describe the growth of a deposit by heterogeneous reactions. The hydrodynamics in the fluid is described by a multicomponent transport model for ionic species diluted in a solvent and heat transfer is taken into account in both liquid and solid domains. The boundary condition at the interface where the reaction takes place is described thoroughly. It involves the reaction kinetics and gives access to the velocity of the interface, ie, the mass rate of the solid deposit. The model is then applied to the case of barite crystallization in a heat exchanger. The liquid phase is therefore composed of two ionic species Ba2+ and SO42− diluted in water. The solid phase is modelled as a homogeneous barite deposit. The fully dynamic CFD simulation of the model is made using Comsol Multiphysics, in a cylindrical pipe. The solid growth is analyzed over time and space in terms of the relevant variables of the model.
