Steaming of wells in the Sacacual sand reservoir of the Santa Barbara field, Monagas State, E. Venezuela, began in Dec. 1964. At that time some 20 wells were producing 1,075 bopd of 16$ to 19$ API naphthenic-base oil with a viscosity range of 120 to 510 cp at the prevailing 85$F reservoir temperature. Net productive intervals range from 40 to 250 ft. The sands dip sharply, resulting in a span of productive depths from 200 ft to 1,150 ft. Original oil-in-place in Meneg's portion of the reservoir is 70 million bbl. A gravity drainage primary recovery of 5.54 million bbl was anticipated. A 25 MMbtu/hr steam plant was installed, along with a distribution network of insulated lines. Within 9 mo., offtake had been boosted to 3,500 bopd, prompting the addition of 11 new outlets. Estimated primary recovery attributable to the new wells is 1.67 million bbl, although these outlets would have been uneconomical to drill if they could not have been steamed. (16 refs.)
