TURN RADIUS [16 records]

Subject field(s)

  • Road Transport
  • Rail Transport
CONT

In connecting straight(tangent) sections of roadway with a horizontal curve, several options are available. The most obvious of these is the simple circular curve, which is just a curve with a single, constant radius. Other options include reverse curves, compound curves, and spiral curves. Reverse curves generally consist of two consecutive curves that turn in opposite directions. They are used to shift the alignment of a highway laterally. The curves used are usually circular and have equal radii.

Record 2 2021-07-14

English

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

A medium turn radius well has at least one section with a build rate angle of between 6° and 20° per 100 ft in the rotary mode, and as much as 35° per 100 ft in an oriented mode, in reaching horizontal. The radius of curvature ranges from about 160 up to 1000 feet.

CONT

Medium-radius wells are appropriate for areas that could benefit from horizontal drilling, but where long-radius methods are either unnecessary or impractical, as would be the case when lease boundary restrictions limit the well course. They are particularly applicable for re-entry wells, reef reservoirs, fractured reservoirs and reservoirs with potential for gas or water coning.

OBS

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.

French

Domaine(s)
  • Extraction du pétrole et du gaz naturel
OBS

Contrairement aux puits verticaux, les puits horizontaux ont une productivité qui est très peu sensible au diamètre du trou. Pour les puits à long rayon de courbure et donc à longue section horizontale (300 m et plus), le diamètre généralement utilisé est de 8,5 pouces. Les puits à faible rayon de courbure, qui nécessitent l'utilisation de garnitures de forage articulées sont forés en plus petit diamètre, 4 pouces généralement.

  • Surveillance and Formalities (Air Transport)
  • Operations (Air Forces)
OBS

If an airport is listed as accredited, U. S. DoD [United Sates Department of Defense], Jeppesen or host nation approach plates may be used. However, criteria used in the development of instrument procedures can be different therefore a review for details such as turn radius, leg lengths, descent gradients, etc. is required. Also, if a commercial FLIP [flight information publication](e. g. Jeppesen, etc.) is used, a comparison review to the host nation's FLIP product should be conducted. Note that some airports may have special accredited status even though the nation is listed accredited.

French

Domaine(s)
  • Aides à la navigation aérienne

OBS

Lorsque l'aéroport se trouve dans un pays classé sous la catégorie «avec accréditation», on peut utiliser les cartes d'approche du DoD [Department of Defense (Département de la défense)] des États-Unis, de Jeppesen ou du pays hôte. Cela dit, il se peut que différents critères aient servi à l'élaboration des procédures d'approche aux instruments. Il faut donc vérifier certains éléments précis comme les rayons de virage, les longueurs de parcours et les pentes de descente, entre autres. De plus, avant d'utiliser une FLIP [publication d'information de vol] commerciale (Jeppesen, etc.), on doit en comparer le contenu à celui de la FLIP du pays hôte. Il est à noter que certains aéroports situés dans un pays «avec accréditation» peuvent porter la mention «avec accréditation spéciale».

Contrairement au scooter électrique à trois roues, le modèle [à] quatre roues est réputé pour son excellente stabilité, grâce à son très bon centre de gravité. Il convient parfaitement aux personnes de forte corpulence. Ce type de scooter électrique permet d'emprunter des routes accidentées ainsi que les chemins en pente raide ou ayant un peu de relief. Sur ce point, le scooter électrique à quatre roues est plus sécurisant que le modèle trois roues.
