C&C Reservoirs is excited to introduce several new additions to the Digital Analogue Knowledge System (DAKS). Aimed to improve overall user experience and functionality, these new features will help facilitate simple, repeatable analysis and benchmarking of global E&P assets.

Release Highlights:

Ain Zalah Field (Iraq) – Located in the Zagros Mountains, this field has an EUR of 295 MMBO and recovery factor of 20% with the oil trapped in a compressional anticline. Production has been intermittent and by 2021 the field was producing at 3871 BOPD.

Akal Field (Mexico) – Situated on the Campeche Shelf, this is the largest field in the Cantarell Complex. The field has an EUR of 14.6 BBO and recovery factor of 46% with the oil trapped in an overthrusted duplex. Initially peaking in 1982 at 960 MBOPD from 50 wells. Implementation of infill drilling, facility expansion and nitrogen gas injection led to a secondary plateau of 2001 MBOPD in 2003-05.

Daqing Field - Xingbei Unit (China) – Onstream since 1966, the unit has a STOIIP of 3947 MMBO and an EUR of 2424 MMBO (61.4% RF), trapped in a heavily faulted inversion anticline. Phased infill drilling, polymer and ASP flooding, acidization, hydraulic fracturing, and artificial lift all contributed to the high recovery factor.  

Gudong Field (China) – Onstream since 1985, the field has a STOIIP of 1851 MMBO and an EUR of 686 MMBO (37% RF) trapped in a broad, faulted, buried-hill draping anticline. Step-out, infill, and horizontal drillings have all been implemented here, along with chemical and thermal EOR methods at various scales to improve recovery.

Margarita-Huacaya Field (Bolivia) – Located in the Chaco-Tarija Basin, this field has EURs of 3355 BCF and 107 MMBC, for gas and condensate recovery factors of 51% and 22%, respectively. A two-year plateau of 636 MMCF/ day and 23,500 BCPD in 2015-16 was achieved with 11 producers. Subsequently offtake began a steady decline and in 2023 production was 424 MMCF/day and 11,200 BCPD.

Okume Complex (Equatorial Guinea) – Hidden in the Rio Muni Basin, group of 5 fields holds a total EUR of 309 MMBO with recovery factor of 24%. Oil pools are stratigraphically trapped in turbidite channel-levee and overbank complexes within two submarine canyons, with over half of the STOIIP in the Elon Field. By end-2021 249 MMBO had been produced.
