“…The filtration and particle concentration along the injection induced fractures were visually inspected and pressure information were used to analyze the impact of filtration and fracture growth on the injectivity. Shumbera et al (2003) reported a prolonged period of good injector performance without any injectivity decline by applying a frac-pack completion in a Gulf of Mexico (GoM) water injection project. In other GoM field cases without frac-packs, reported by Sharma et al (2000), the injectivity declined quickly and was affected by reservoir conditions or changes in water quality.…”

The filtration of solids in the injection water in a frac-pack is the primary factor which controls the injectivity decline in fracpacked water injection well completions. The injectivity may decline rapidly or much more slowly depending on the degree of frac-pack filtration. The widening and lengthening of frac-packs and the associated loss of sand control are affected as well. However, there is no experimental data for the filtration coefficient in high velocity flows in frac-packs. In this research, the filtration coefficients were experimentally measured in high velocity flows encountered in frac-packs. The solid concentrations and pressure drops across proppant pack sections were measured to properly utilize filtration theory and permeability decline models. The filtration coefficients were measured at various flow rates and for different proppant sizes. Our experiments show that at high fluid velocities, the filtration coefficient is significantly lower than that estimated from prior correlations that are based on low velocity filtration.Our experimental results were used to obtain new empirical correlations for filtration coefficients at high flow rates in fracpacks. The experimental coefficients were used as the primary input into a well injectivity model. The proper estimation on the filtration enabled us to analyze the impact of injection rates and proppant selection on injector performance, i.e., predict longterm injection well behavior. The effect of particle filtration in the frac-pack and its effect on injector performance was captured accurately for the first time. The empirical correlations together with a model for frac-pack growth in the injection well allowed us to accurately estimate fracture dimensions and the long-term water injectivity of frac-packed injectors. These results can be used for frac-pack design, proppant selection and specification of injection water quality.

“…Perkins and Gonzales (1985) focused on thermoelastic stress changes caused by the injection of cold water and its impact on fracture growth. Suarez-Rivera et al (2002) investigated experimentally the fracture propagation caused by injecting various types of particle suspensions into large blocks of rocks. The concentration, shape, size, and compressibility of particles greatly affect the fracture-growth rate and leakoff behavior in their study.…”

The filtration of solids in the injection water in a frac pack is the primary factor controlling the injectivity decline in frac-packed waterinjection-well completions. The injectivity may decline rapidly or much more slowly, depending on the degree of frac-pack filtration. The widening and lengthening of frac packs and the associated loss of sand control are affected also. However, there are no experimental data available for the filtration coefficient at high velocities that are typical in frac packs. In this research, the filtration coefficients were measured experimentally in high-velocity flows encountered in frac packs. The solid concentrations and pressure drops across proppantpack sections were measured and correlated with earlier filtration theory and permeability-decline models. The filtration coefficients were measured at various flow rates and for different proppant sizes. Our experiments show that at high fluid velocities, the filtration coefficient is significantly lower than that estimated from prior correlations that are based on low-velocity filtration.We have developed new empirical correlations for filtration coefficients at high flow rates in frac packs. The improved filtration coefficients were used as the primary input into a well-injectivity model. The proper estimation of the filtration enabled us to more accurately analyze the impact of injection rates and proppant selection on injector performance (i.e., predict long-term injection-well behavior). The effect of particle filtration in the frac pack, and its effect on injector performance, was captured accurately for the first time. The newly presented empirical correlations coupled with a model for frac-pack growth in the injection well allowed us to estimate accurately the fracture dimensions and the long-term water injectivity of frac-packed injectors. These results can be used for frac-pack design, proppant selection, and specification of injection-water quality.Effect of Frac-Pack Filtration on Injectivity.
