In this field case the adaptive inflow ,control, system (AICD) 2 7/8’’ is installed as a secondary completion inside 4 ½’’ liner with multi-stage frac for inflow ,profile, regulation, water breakthrough prevention and ,control, of proppant ,backflow,. In this case AICD limits the production rate for the each interval on a predetermined level.

The calibrated microscale properties (Tables 1 and 2 are used as input parameters in the model shown in Figure 2.Numerical modeling of fracture closing and ,fracturing fluid, flowback is then calculated. Figures 9 and 10 plot the profiles of a proppant pillar at two different closing stresses, 20.7 MPa and 41.4 MPa, respectively. The height of the proppant pillar is 6 mm, and the diameter is 10 mm.

Backflow, must be applied cautiously (i.e., in stable formations). It was established in the Soft Formations Workshop that ,backflow, in unconsolidated formations is undesirable. Access to lower permeability formations may be encouraged if a ,backflow, rate is established to remove perforation or other completion damage/debris.

Frequent monitoring and ,control, of pH is essential for maintaining adequate levels of free residual chlorine. Above a pH of 8.0, chlorine effectiveness is greatly reduced. Proper ,control, of pH will maintain the effectiveness of chlorination and minimize corrosion. Bromine is an effective oxidizing biocide.
