MICROEMULSION SLUG [4 records]

Record 1 2008-01-23

English

Subject field(s)
  • Oil Production
CONT

In each flood a 5% PV microemulsion slug was injected into a 4 ft x 1-in x 1-in Berea core initially containing discontineous residual oil and 1% NaCl.

French

Domaine(s)
  • Production pétrolière
CONT

Le coût essentiel de l'opération provient du polymère, utilisé en bouchon de l'ordre de 10 à 30 % du volume des pores du réservoir.

Record 2 2001-11-06

English

Subject field(s)
  • Chemical Engineering
  • Oil Production
CONT

In each flood a 5% PV microemulsion slug was injected into a... Berea core... All slug compositions used 15% surfactant with varying amounts of oil...

French

Domaine(s)
  • Génie chimique
  • Production pétrolière
OBS

Utilisation de micro-émulsions. [...] Ce procédé [...] consiste a utiliser des émulsions eau-huile dont la phase continue est extrêmement divisée [...] L'intérêt [...] de ces fluides tient dans la possibilité de passage continu depuis la micro-émulsion dans laquelle l'huile est phase continue, au cas inverse de la micro-émulsion à phase continue d'eau.

Record 3 1988-01-23

English

Subject field(s)
  • Oil Production
CONT

As mixing progresses, the maximum surfactant concentration in the microemulsion slug decreases and eventually exits the miscible region; i. e., slug breakdown occurs and the locally miscible flood becomes an immiscible displacement.

French

Domaine(s)
  • Production pétrolière
CONT

La taille du banc de solvant pur ne cesse de décroître au fur et à mesure du balayage. Il y a lieu d'éviter que la largeur de ce banc ne s'annule avant la percée du mélange H-S au puits de production, car cela signifierait que C et H sont entrés en contact; or C et H ne sont pas miscibles. Quand un tel incident se produit, on dit qu'il y a «rupture de miscibilité».

OBS

Dans le texte ci-dessus H = huile, S = solvant, C = fluide de chasse non miscible avec H.

Record 4 1988-01-23

English

Subject field(s)
  • Oil Production
CONT

Healy and Reed(1974) conducted a series of constant-rate... core floods to determine if the nature of the external phase affects displacement efficiency. In each flood a 5% PV microemulsion slug was injected... there appears to be no obvious advantage attributable to either oil-external or water-external surfactant slugs.

French

Domaine(s)
  • Production pétrolière
CONT

L'intérêt essentiel de ces fluides tient dans la possibilité de passage continu depuis la micro-émulsion dans laquelle l'huile est phase continue, au cas inverse de la micro-émulsion à phase continue eau.
