Abstract: The invention addresses to a flow uniformization process for the entire useful life of a horizontal well, which associates the use of divergent sand containment screens or divergent liner. For the manufacture of divergent liners, flow simulations are carried out via computational fluid dynamics as a function of the dimensions of the horizontal well, outer diameter and length of the liner, static pressure, expected flow pressure, expected oil flow rate, oil viscosity, API degree, planned length for the horizontal well. These simulations simulate the area open to flow along the horizontal section. Additionally, well stimulation methods, scale removers and, optionally, sand containment are used.

Abstract: The invention proposes a tool for flow uniformization in stimulation operations that uses a washing string with divergent perforation, provides a better direction of stimulation and, therefore, a better management of the reservoir. The technology can be applied entirely through the wells area, being addressed to the reservoirs area in the management of reservoirs; wells stimulated in a homogeneous way will have fewer problems of premature cones of water and/or gas, and in the lift and flow area will contribute to improving the guarantee of flow of production from the wells. It can be applied as a technology in the intervention of wells in the phase of restoration of productivity, through operations of injection of acid in the reservoir as well as operations of squeeze of scale inhibitor.
