Blake (UK) – Two reservoirs, both in Lower Cretaceous turbidites, with development focused on the main, excellent-quality, stacked channel-sands reservoir, by six horizontal producers and two water injectors. The poorer-quality thin-sheetsands reservoir, though larger, is sparsely developed.
Buchan (UK) – Tight and fractured Devonian fluvial sandstone reservoir. Crestal water injection was largely unsuccessful, but water-cut was still <60% after 40 years’ production.
Chichimene (Columbia) – Two reservoirs, one in good-quality Eocene fluvial sands with recovery of the extra-heavy oil aided by water injection, EPSs and infill drilling. The other, minor reservoir consists of moderate-quality Upper Cretaceous deltaic/estuarine sands, producing heavy oil under aquifer drive.
Heletz (Israel) – Onstream since 1955, this faulted and layered coastal-sandstone, medium-gravity oil reservoir has been produced without pressure support and field life has been sustained by infill and step-out drilling.
Maari (New Zealand) – Offshore development of low-moderate quality, Miocene slope-fan turbidites using horizontal wells recompletions. IR methods include water injection and sidetrack infill drilling.
Vankor (Russia) – Multi-reservoir, supergiant oil & gas field, onstream since 2009, with production from layered, shallow-marine Lower Cretaceous reservoirs through multilateral wells light, aided by water injection and polymer conformance improvement measures.
Covenant (USA) – Lower Jurassic aeolian-dune sandstone reservoir with high N:G, but fault-compartmentalized, producing low-GOR oil under strong aquifer drive.
