Project Profile
Value: undisclosed
Location: 60 kilometres from Kulsary, Atyrau oblast, northern Spain
Reserves: 104 mmbbls STOIIP P50
Area: unknown
Production: 196 bopd
Start-up year: 2011
The Ayoluengo field contains 104 mmbbls STOIIP P50 and LGO estimates that between 10 and 20 mmbbls of additional oil recovery is possible using existing technology if deployed in the wells available for injection and production. Reservoir studies and geological correlations incorporating the results of the recent intervention program will be combined with a more detailed reinterpretation of the reprocessed 3D seismic to determine the initial phase of gas injection, which could start as early as the second quarter of 2012. Eight of the 53 wells available were investigated during the well intervention and work-over program carried out between April and July 2011. The company has studied the results with a view to planning further work on some of those wells and on other wells with similar characteristics. Leni Gas & Oil remains confident that the ultimate recoverable reserves in the field will be best produced through the implementation of secondary and tertiary recovery techniques with the preferred EOR scheme considered to be a nitrogen flood.
In 2014, the production in the Ayoluengo Field in northern Spain has in overall terms been rising in recent months with 157 bopd reported for 2 December. Recent clean outs on two wells have led to their return to production levels of approximately 20 bopd per well and it is expected that an additional 5 wells will be reworked progressively over the coming months. Production from Ayoluengo Field on 12 November reached a recent high of 196 bopd when well Ayo-40 was swabbed back into production after mechanical removal of scale and an acid wash.
