The process by which multiple fractures are created along the horizontal section of the wellbore in a series of consecutive operations.  1, fiche 1, Anglais, - horizontal%20multistage%20hydraulic%20fracturing

Record number: 1, Textual support number: 1 CONT

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 1, Anglais, - horizontal%20multistage%20hydraulic%20fracturing

Record number: 1, Textual support number: 1 OBS

The terms "fraccing" and "fracing," short for "fracturing," are pronounced "fracking."  6, fiche 1, Anglais, - horizontal%20multistage%20hydraulic%20fracturing

Record number: 2, Textual support number: 1 CONT

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 2, Anglais, - horizontal%20hydraulic%20fracturing

A rock formation with low permeability and porosity containing an accumulation of oil.  2, fiche 3, Anglais, - tight%20oil%20reservoir

Record number: 3, Textual support number: 1 CONT

The percentage of pore volume ... within the rock is generally less than 30% and in tight oil reservoirs is commonly less than 10%.  3, fiche 3, Anglais, - tight%20oil%20reservoir

Record number: 3, Textual support number: 2 CONT

Tight oil reservoirs typically require the combination of horizontal drilling and multi-stage hydraulic fracturing to establish sufficient fluid flow to achieve economic rates of recovery.  4, fiche 3, Anglais, - tight%20oil%20reservoir
