Two field pilot tests of immiscible water-alternating gas (WAG) injection are being conducted in Chihuido de la Sierra Negra, the largest oilfield in Argentina. Immiscible gas injection technology was selected because of its attractive incremental oil recovery potential for the two main reservoirs in this field. These are mature, waterflooded, unde...

This paper describes preparations for an air injection pilot into a mature waterflooded light oil reservoir in Barrancas field, Argentina. Primary development started in 1954, with waterflooding beginning in 1967.As the reservoir characteristics are quite similar to economically viable air injection projects in the Williston Basin, the feasibility...

... The main factors influencing the WAG flooding include reservoir wettability, reservoir heterogeneity, reservoir rock and fluid properties, injection techniques, and WAG parameters (slug size and WAG ratio) (Righi and Pascual, 2007). Two of the most important economic parameters affecting the WAG flooding are slug size and WAG ratio. ...
... Other reported successful air injection projects include Chevron-owned W. Heidelberg Gulf and Total owned Handil oilfields in Indonesia (Gillham et al., 1997;Pascual et al., 2005;Duiveman et al., 2005). In China, there have been a few field projects of light oils, including the Baise oilfield (1996), H-12 and M-15 Blocks in Zhongyuan oilfield (2006), Shengli oilfield (2007) (Hongmin et al., 2008;Niu et al., 2011). ...
... Motivated by the success of this field application, the second CO 2 immiscible project in United States was conducted in the nearby Lick Creek Field in 1975, where 7.6 Bscf of CO 2 was injected into a reservoir with a net thickness of 8.6 ft and an oil gravity of 17°API. Over the decades, a considerable amount of CO 2 immiscible projects has been undertaken not only in the United States, but also in China [17][18][19][20], Turkey [21][22][23][24], Trinidad [25], Malaysia [26][27][28][29], Hungary [22,30,31], Argentina [32,33], Canada [21,34,35], and Brazil [36,37]. Currently, more projects are being planned in oil fields in Thailand and China (Yanchang oil field [38], Shengli oil field [39]). ...
