Well Tool Having a Removable Collar for Allowing Production Fluid Flow

A system includes a first tubular body, a second tubular body, and a collar. The first tubular body can be positioned in a wellbore. The first tubular body includes a first outer wall defining a first inner area and includes a first opening therethrough. The first opening for forming a first flow path to allow fluid flow between the first inner area and a first outer area of the first tubular body through the first opening during a hydraulic fracturing process and subsequent to the hydraulic fracturing process. The second tubular body can be positioned in the wellbore and longitudinally coupled to the first tubular body. The second tubular body includes a second outer wall defining a second inner area that is fluidly coupled to the first inner area and includes a second opening therethrough. The second opening can form a second flow path to allow fluid flow between the second inner area and a second outer area. The collar is positioned in the second inner area of the second tubular body for preventing fluid flow between the second inner area and the second outer area of the second tubular body through the second opening during the hydraulic fracturing process. The collar can be removed for forming a flow path to allow production fluid to flow between the second inner area of the second tubular body and the second outer area of the second tubular body through the second opening subsequent to the hydraulic fracturing process.
