Zur LanganzeigeZusammenfassung
The fracturing process can be divided into three stages: creating a crack, maintaining it in an open state, and pumping the fracturing solution from the well.
In order to create a crack in the formation, it is necessary to increase the rock breaking factor. This is achieved by pumping a certain solution into the formation at a rate faster than the one at which the formation could accept. The pressure of the injected liquid is increased until the compressive forces in the formation increase and the rock does not break [1, 2].
When a crack appears, proppant is added to the solution, which is carried into it by the flow of liquid. The concentration of proppant will increase until it provides a good crack seal. When the process is complete, the pressure is reduced, the proppant holds the fracture open and conducts reservoir fluids.
