“…After the chemical treatment is injected into the rock from the well, post-treatment fluid is typically used to clean-up the well and as a result the finite volume of treatment fluid is displaced by the post-treatment fluid, and forms an annulus some distance beyond the well. Talaghat, Esmaeilzadeh & Mowla (2009) describe how it is difficult to obtain a uniform front of the injected chemical owing to the time-constraint of injecting the treatment as quickly as possible, since the well is unproductive during such interventions. Any break-up or fingering of the treatment fluid might lead to regions in which the treatment fluid is unable to form a competent bond designed to prevent sand production.…”

We examine the stability of a system with two radially spreading fronts in a Hele-Shaw cell in which the viscosity increases monotonically from the innermost to the outermost fluid. The critical parameters are identified as the viscosity ratio of the inner and outer fluids and the viscosity difference between the intermediate and outer fluids as a fraction of the viscosity difference between the inner and outer fluids. There is a minimum viscosity ratio of the inner and outer fluids above which, for each azimuthal mode, the system is stable to perturbations of that mode at any flow rate. This condition is directly analogous to the result for a single interface. Below this minimum ratio, the system may be stable at any flow rate early in the flow. However, once the inner radius reaches a critical fraction of the outer radius, this absolute stability ceases to apply owing to the coupling of the inner and outer interfaces. We determine the maximum flow rate, as a function of time, in order that all modes remain stable due to the effects of interfacial tension. These criteria for stability are then used to select the viscosity of the intermediate fluid so that a fixed volume of the intermediate and then inner fluid can be added to the system in the minimum time with the system remaining stable throughout. The optimal viscosity for this intermediate fluid depends on the relative volume of the inner and intermediate fluid and also on the overall viscosity ratio of the innermost fluid and the original fluid in the cell, with the balance being to suppress the early time instability of the outer interface and the late time instability of the inner interface. We discuss application of this approach to a problem of injection of treatment fluid in an oil well.

“…The resulting glass can be dissolved in water, steam and much pressure, to make liquid sodium silicate. Sodium silicate solutions, also called water glass, have, according to the SiO 2 /Na 2 O molar ratio, many diversified industrial applications, such as sealants, deflocculants, emulsifiers and buffers in abrasive, casting industries… These solutions are also used as reactants during the formation of geopolymers [1,2] and as binder for the consolidation of sand to prevent or inhibit sand movement with the fluids produced from hydrocarbon-bearing earth formations [3,4] or to form a core binder hardened when gassing with CO 2 in the sand cast process. The agglomeration of sand by sodium silicate solution is also used in fuse technology [5,6] as a filler material.…”
