HORIZONTAL FRACTURE [11 records]

Record 1 2021-07-14

English

Subject field(s)
  • Oil Drilling
CONT

When sufficient hydraulic pressure is applied through the wellbore against a particular formation, the formation rock fractures along the plane perpendicular to the direction of the least principal stress. A horizontal fracture will be created if fracture pressure is greater than overburden pressure; a vertical fracture will occur if overburden pressure is greater.

Record 2 2021-07-14

English

Subject field(s)
  • Oil Drilling
DEF

The process by which multiple fractures are created along the horizontal section of the wellbore in a series of consecutive operations.

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. "

OBS

The terms "fraccing" and "fracing," short for "fracturing," are pronounced "fracking."

Record 4 2017-08-25

English

Subject field(s)
  • Petroleum Deposits
  • Research and Development (Petroleum Tech.)
DEF

A rock body with low permeability and porosity where hydrocarbons have accumulated.

CONT

... a tight reservoir is a reservoir from which gas or liquids cannot be produced at economic flow rates nor recover economic volumes of natural gas unless the reservoir is stimulated by hydraulic fracture treatment or produced by use of a horizontal wellbore or multilateral wellbores.

French

Domaine(s)
  • Gisements pétrolifères
  • Recherche et développement (Technol. pétrol.)
DEF

Ensemble de roches avec une porosité et une perméabilité très faibles où il y a une accumulation d'hydrocarbures.

CONT

Une accumulation de gaz dans un réservoir compact peut venir d'une très forte réduction de la vitesse de migration.

Spanish

Campo(s) temático(s)
  • Yacimientos petrolíferos
  • Investigación y desarrollo (Tecnología petrolera)
DEF

Formación rocosa de baja permeablidad y porosidad donde se acumulan los hidrocarburos.

CONT

Reservorios compactos (tight). [La] permeabilidad [de la roca] (facilidad de los fluidos para moverse dentro de ella) [...] es tan baja, que no permite el flujo del gas hacia el pozo, aunque no tanto como la de los esquistos y lutitas.

Record 6 2012-03-07

English

Subject field(s)
  • Geology
  • Oil and Natural Gas Extraction
CONT

... horizontal drilling is usually undertaken to achieve important technical objectives related to specific characteristics of a target reservoir [such as] the reservoir rock's permeability, which is its capacity to conduct fluid flow through the interconnections of its pore spaces(termed its "matrix permeability"), or through fractures(its "fracture permeability"), and/or the expected propensity of the reservoir to develop water or gas influxes deleterious to production, either from other parts of the reservoir or from adjacent rocks, as production takes place(an event called "coning").

French

Domaine(s)
  • Géologie
  • Extraction du pétrole et du gaz naturel
DEF

Perméabilité secondaire artificiellement créée par les fractures provoquées dans un milieu rocheux.

OBS

La fracturation est un procédé utilisé dans l'extraction du pétrole pour augmenter, en y pratiquant des fractures, la perméabilité de la couche productrice.

OBS
