DEF

[A] polymer [which is a] film containing nine billion pores per square inch.

CONT

The Gore-Tex membrane is a patented composite of two unique polymers. The first polymer, expanded polytetrafluoroethylene(ePTFE)... The second polymer is an oleophobic("oil heating") material...

OBS

Each pore [of the film] is 20,000 times smaller than a raindrop, but 700 times larger than a molecule of water. It is completely impervious to rain, snow and sleet and allows perspiration vapor to pass through.

French

Domaine(s)
  • Éléments et composés chimiques
  • Matières plastiques
  • Textiles artificiels et synthétiques
DEF

[Polymère consistant en] une pellicule comptant neuf milliards de pores au pouce carré.

CONT

Le ePTFE (polytétrafluoroéthylène expansé) est obtenu par frittage du PTFE [polytétrafluoroéthylène] suivi d'un extrusion et d'un étirage. Ce procédé de fabrication particulier confère au matériau souple ePTFE une structure alvéolaire ouverte, composée de deux entités de base, le nodule et la fibrille.

OBS

Chaque pore [de cette pellicule] est vingt mille fois plus petit qu'une goutte de pluie, mais 700 fois plus large qu'une molécule d'eau. Il bloque parfaitement la pluie et la neige, tout en permettant la diffusion de la vapeur de transpiration.

Subject field(s)
  • Chemistry
  • Oil Production
CONT

The injected slug is formulated with three or more components. The basic components (hydrocarbon, surfactant and water) are sufficient to form the micellar solutions. A cosurfactant fourth component (usually alcohol) can be added.

CONT

Improved cosurfactants help surfactant/polymer flood performance. In the earlier system designs, simple alcohols... were used... Ethoxylated alcohol use... shows much promise as an improved cosurfactant. These chemicals have resulted in improved oil recovery and allow slugs to be tailored for higher salinity and temperature.

French

Domaine(s)
  • Chimie
  • Production pétrolière
CONT

Pour obtenir une microémulsion avec des gouttelettes de 100 angströms il faut [...] diviser par dix mille la tension interfaciale de départ. En ajoutant un simple tensioactif ce serait impossible. [...] C'est pour cela qu'il faut recourir le plus souvent à un deuxième tensioactif. Ce «cotensioactif» est d'autant plus efficace qu'il est partiellement soluble dans l'eau et dans l'huile, comme certains alcools.

Record 24 2000-05-30

English

Subject field(s)
  • Oil Production
CONT

The polymer flooding technique involves the addition of a thickening agent(polymer) to the injected water to increase its viscosity [thus yielding] two benefits : 1) [it] reduces the total volume of water required to reach the ultimate residual oil saturation and 2) increases swell efficiency due to improved mobility ratio.

French

Domaine(s)
  • Production pétrolière
OBS

Le passage d'une solution de polymères à travers un milieu poreux entraîne une réduction rémanente de mobilité à l'eau [...] Par contre la mobilité à l'huile reste à peu près inchangée.

Record 25 2000-05-30

Subject field(s)

CONT

Among other properties of polymer flooding that enhance the oil recovery is the existence of inaccessible pore volume... They argued that inaccessible pore volume would have a favourable effect... as polymer response would be left by the production well sooner than expected.

Sodium-based dechlorination processes can be used to decontaminate mineral oil containing up to a few thousand parts per million PCBs... the sodium reagent reacts with the chlorine atoms on the PCB molecule to form sodium chloride, and the biphenyl part of the PCB molecule polymerizes to form a non-chlorinated polymer(polyphenylene) ;the mineral oil is unchanged. Sodium chloride and polyphenylene are the wastes from this process.

CONT

A stabilized oil bank will build up ahead of the slug.... this oil bank will flow with a certain mobility. The surfactant slug's mobility should be less than the oil bank mobility. Likewise, for efficient displacement the mobility control polymer should be less mobile than slug and oil banks. Loss of mobility control in the fluid sequence will cause fingering and reduced displacement efficiency.
