... in many shale formations, the fracing process is repeated a number oftimes in isolated segments along the length of the wellbore. This is multistagefracing, which increases the well' s production by stimulating a larger portion of the underground formation. The multiple stages set for fracing may be along vertical or horizontal wellbores, and in new or existing wells.  10, fiche 1, Anglais, - multi%2Dstage%20hydraulic%20fracturing

Using mechanical means or fluid pressure, each segment of the horizontal wellbore is isolated and fractured individually. Frac fluid is pumped from the surface at a predetermined and constantly monitored rate to the "toe," the farthest isolated segment in the horizontal section. When the fracture is created, proppant-laden fluid is pumped into the fracture to keep it open. Once complete, the process is repeated for each segment in the wellbore, working back towards the "heel."  1, fiche 2, Anglais, - horizontal%20multistage%20hydraulic%20fracturing

Horizontal hydraulic fracturing is accomplished by drilling vertically to the depth of the shale formation, which is generally found between 0.6 – 1.5 km below the surface. When the gas-containing shale is intercepted, the drill bit is maneuvered to travel horizontally through the center of the formation for a distance of up to 1.6km. Water, biocides, surfactants, sands, and other chemicals are forced into the borehole under extremely high pressure to induce fractures in the shale that allow gas to rise to the surface for collection ...  1, fiche 3, Anglais, - horizontal%20hydraulic%20fracturing
