Record 1 2021-07-14

English

Subject field(s)
  • Oil Drilling
CONT

A hydraulic fracture is formed by pumping the fracturing fluid into the wellbore at a rate sufficient to increase the pressure downhole to a value in excess of the fracture gradient of the formation rock. The pressure causes the formation to crack, allowing the fracturing fluid to enter and extend the crack farther into the formation. To keep this fracture open after the injection stops, a solid proppant, commonly a sieved round sand, is added to the fracture fluid. The propped hydraulic fracture then becomes a high permeability conduit through which the formation fluids can flow to the well.

Domaine(s)
  • Forage des puits de pétrole
OBS

La fracture hydraulique se forme dans une formation rocheuse après que celle-ci ait subi une opération de fracturation hydraulique.

Record 2 2021-07-14

English

Subject field(s)
  • Oil Drilling
CONT

During the hydraulic fracturing process, some of the fracturing fluid may leave the fracture and enter the targeted formation adjacent to the created fracture (i.e. untreated formation). This phenomenon is known as fluid leak-off. The fluid flows into the micropore or pore spaces of the formation or into existing natural fractures in the formation or into small fractures opened and propagated into the formation by the pressure in the induced fracture.

French

Domaine(s)
  • Forage des puits de pétrole
DEF

Phénomène se produisant lorsque le liquide de fracturation hydraulique s’écoule de la fracture principale et s’infiltre dans une autre partie de la formation ou dans un autre réseau de fractures.

Record 3 2002-01-22

English

Subject field(s)
  • Oil Drilling
DEF

An operation designed to loosen or break up tight formations which contain oil or gas, thus causing such formations to have more permeability and greater production.

OBS

This operation involved the injection of a mixture or blend of crude oil and sand into the producing formation under high pressure by means of pressure pumps, followed by injections of rubberized nylon balls to seal off the fractured formation.

French

Domaine(s)
  • Forage des puits de pétrole
DEF

Fracturation hydraulique utilisant de l'huile brute comme fluide de fracturation et du sable comme agent de soutènement de la fracture créée.
