Record 4 1999-09-30

English

Subject field(s)
  • Oil Drilling
CONT

Most horizontal wells have targeted crude oil reservoirs. Its successful employment ... has encouraged testing of it in many geographic regions and geologic situations. The technical objective of horizontal drilling is to provide economic benefits by exposing significantly more reservoir rock to the well bore surface than can be achieved via drilling of a conventional vertical well. ... Horizontal bore hole length grew rapidly and horizontal displacements have now been extended to over 8,000 feet. Some wells have featured multiple horizontal bores. ... Based on curvature rate, the most commonly used classification for types of horizontal wells are as follows: ultra-short radius, short radius, medium radius and long radius.

OBS

rw: the letter "w" is subscripted.

Key term(s)
  • wellbore radius
  • radius of a well

French

Domaine(s)
  • Forage des puits de pétrole
CONT

[Géométrie des puits horizontaux.] Le rayon de courbure de la partie de trajectoire qui relie la section verticale à la section horizontale dépend de plusieurs facteurs : - le déplacement horizontal recherché entre la localisation en surface et l'entrée dans le réservoir, - la position verticale du début de la déviation («kick-off point»), - la longueur de drain horizontal à forer, - les contraintes de complétion. D'une manière générale les longs rayons de courbure, supérieurs à 250 mètres, permettent de forer de plus longues sections horizontales et facilitent la complétion. Les longs rayons de courbure sont surtout utilisés pour les puits de développement alors que les courts rayons s'appliquent essentiellement aux opérations de recomplétion.

Record 5 1994-04-20

English

Subject field(s)
  • Aeronautical Engineering and Maintenance
CONT

Bend allowance depends on four factors: (1) The degree of bend, (2) The radius of the bend, (3) The thickness of the metal, and (4) The type of metal used. The radius of the bend is generally proportional to the thickness of the material. Furthermore, the sharper the radius of bend, the less the material that will be needed for the bend.
