ARTIFICIAL LIFT [7 fiches]

Fiche 1 2007-08-17

Anglais

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

A method of lifting oil from the bottom of a well to the surface by the use of compressed gas.

CONT

Many oil wells do not have a formation pressure high enough to push the oil... to the surface. In these cases, some artificial method for lifting the oil to the surface must be installed. [A] method, called gas lift, uses the buoyancy of a bubble of gas in the tubing to push the oil to the surface.

OBS

The gas is pumped into the hole and at the lower end of the tubing it becomes a part of the fluid in the well. As the gas expands, it lifts the oil to the surface.

Terme(s)-clé(s)
  • gas lifting
  • gas lift method

Français

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

Procédé d'exploitation des puits de pétrole par injection de gaz provoquant l'allégement par émulsion de la colonne d'huile.

CONT

[...] la plupart des puits ne sont pas jaillissants et on doit avoir recours à un procédé d'extraction artificielle : pompage, ascension par poussée de gaz, etc.

CONT

Extraction de pétrole par injection de gaz.

OBS

allègement : Cette graphie, puisée des Rectifications de l'orthographe recommandées par le Conseil supérieur de la langue française, est attestée dans le Petit Robert (2004).

Fiche 2 2005-02-15

Anglais

Subject field(s)
  • Petroleum Technology - Equipment
  • Photoelectricity and Electron Optics
CONT

Production optimization solutions consisting of well-site computer hardware, desktop analysis software, fiber-optic intelligent-well technology used in the oil and gas industry to remotely monitor and optimize downhole conditions and well production.

CONT

eProduction Solutions, Inc. is the world leader in production optimization solutions for flowing wells and all forms of artificial lift. The company provides advanced fiber optic intelligent well technology with well site and desktop intelligence as well as control systems for onshore and offshore production. eP provides hardware and software solutions for comprehensive production operations optimization including real-time monitoring, controlling, designing, and analyzing production oil and gas wells and facilities.

OBS

intelligent well technology: Technology that combines sensors and remote control to detect production problems and solve them without costly well intervention.

OBS

Optimizing reservoir performance with intelligent well technology. ... IWT is a key building block of real time reservoir management. By placing sensors and control valves at the reservoir face, teams of petroleum engineers can monitor reservoir and well performance in real time, analyze data, make decisions and modify the completion without physical intervention, to optimize asset performance.

OBS

... with advancements in material science, electronics, and data acquisition and processing, we have seen the use of sensors in oil well production turn in to what is now being referred to as "smart-well technology." With sensors located downhole (below ground), above ground, in the storage tanks, and even on the pump motors to detect low frequency vibrations that can indicate potential wear, "smart" is exactly what these wells are becoming. ... There are a variety of sensors currently used for downhole monitoring ranging from fiber optic to acoustic to quartz crystal sensors.

OBS

De nouvelles méthodes géophysiques et analytiques seront testées : [...] capteur à fibre optique pour l'enregistrement des déformations dans le forage; contrôle permanent des fluides chimiques dans les puits et diverses sources; réseau permanent d'électrodes dans les puits cimentés pour la surveillance de l'écoulement des fluides [...]

OBS

Les chercheurs d'ISIS utilisent un matériau plus solide et doté d'une durée de vie plus longue que les matériaux conventionnels pour la construction d'infrastructures. À ce matériau, ils ajoutent des réseaux de capteurs à fibres optiques et des faisceaux laser ce qui leur permet de surveiller en tout temps les tensions et les contraintes exercées sur les structures [...] La technologie «intelligente» d'ISIS peut également servir à recouvrir ou à rapiécer les structures de béton existante afin d'améliorer leur rendement et leur durabilité.

Fiche 3 2003-11-13

Anglais

Subject field(s)
  • Petroleum Deposits
OBS

Oilfields, after a certain production period, are then called mature fields. Mature fields are those where the recovered oil fraction is close to the final recovery factor. Its mature phase is generally accompanied by an increasing production of water or gas, plus the aging of surface and subsurface equipment. To revitalize mature fields, a series of technologies is developed to increase the final recovery factor through treatments on a field (the so-called tertiary petroleum recovery) or well (stimulation, recompletion, treatments and logging) scale, in addition to optimizing the techniques relating to oil lift, its surface flow and treatment.

OBS

Many mature gas fields also have a fairly significant production decline, especially when development drilling has come to an end. These mature fields can be revitalized in many ways. In some instances, efforts are focused on the reservoir with further drilling to drain potentially unswept hydrocarbons with infill wells or horizontal laterals. The horizontal drilling might be from new wellbores or wells that are currently temporarily abandoned or near their economic limit. With the increase in horizontal-well activity, there is an abundance of new technology with advances in gravel-pack design, underbalanced drilling with coiled tubing, and coiled-tubing fracturing. Besides these production improvements, operators are revamping both downhole and surface facilities to help breathe new life into older fields. Advances are taking place in the areas of artificial lift, intelligent-well completions, expandable tubulars, and others.

Anglais

Subject field(s)
  • Oil Production
DEF

Any method used to raise oil to the surface through a well, after reservoir pressure has declined to the point at which the well no longer produces by means of natural energy.

CONT

Sucker-rod pumps, hydraulic pumps, submersible pumps, and gas lift are the most common methods of artificial lift.

Subject field(s)

By giving a cognitive enhancer, with minimal side effects, to people without a mental deficit, they may end up with cognitive credit, i. e. smarter. Some elements within the scientific establishment continue to deny the potential of cognitive enhancers. They believe that the optimal brain cannot be improved upon by throwing in, a "chemical spanner". But optimal memory can be improved, for example, by employing "mnemonics", which is as "artificial" as a chemical lift from a pill. Would they also resist cognitive enhancement by other artificial methods such as food-a "chemical spanner" if ever there was one-and education? The United States Congress has declared the 1990s the "Decade of the Brain". Smart drugs will, if regulated, treat a recently officially recognized disease, the Age-Associated Memory Impairment(AAMI)-a noticeable mental decline due to the normal ageing process. A futures analyst, Decision Resources, predicts that smart drugs could benefit 600 million people this decade, including 60 million people with AAMI, 20 million students who want to improve scholastic performance, and 270 million people hoping to improve their efficiency at work(Suppl. The World in 1994).

OBS

See "cognitive enhancer".
