Title (EN) METHOD FOR PRODUCING HEAVY CRUDE OIL
(FR) PROCEDE DE PRODUCTION DE PETROLE BRUT LOURD
Abstract: front page image
(EN)Oil treatment processes and an oil treatment facility (10) for improving the properties of heavy crude oil with respect to production, transportation, refining, and product market value. The basic process comprises injecting heavy crude oil with a liquid that is volatile and/or miscible with the oil, the liquide preferably being hydrocarbon condensate. The injected liquid reduces the viscosity and density of the heavy oil. When injected into oil at or near the lower end of the well (12), the hydrostatic head is reduced, and hydraulic losses associated with lifting the oil to the wellhead (14) are also reduced. When injected into a stream of heavy oil prior to oil/water separation (30, 50), the settling velocity of droplets of oil or water is increased.
(FR)Procédés et installation (10) de traitement de pétrole permettant d'améliorer les propriétés de pétrole brut lourd du point de vue de la production, du transport, du raffinage et de la valeur de marché du produit. Le procédé de base comporte l'étape consistant à injecter dans le pétrole brut lourd un liquide volatil et/ou miscible avec le pétrole, ce liquide étant de préférence un condensat d'hydrocarbure. L'injection de ce liquide permet de réduire la viscosité et la densité du pétrole lourd. Lorsque ce liquide est injecté dans le pétrole à l'extrémité inférieure du puits (12) ou à proximité de celle-ci, la pression hydrostatique est réduite ainsi que les pertes hydrauliques associées à l'extraction du pétrole en direction de la tête de puits (14). L'injection de ce liquide dans un flux de pétrole lourd avant séparation (30, 50) pétrole/eau permet d'accroître la vitesse de sédimentation des gouttelettes de pétrole ou d'eau.
