This might be 20 or 30 times—but a process that typically takes only a few days to finish. STEP 6: Production and Fracking Fluid Recycling. Once fracking is completed, production begins. Oil and natural gas flows up from the well bore and fracturing fluid is then recovered and recycled and used in other fracking operations.
