Mailisu Project
The West Mailisu oilfield lies up-dip of the Mailisu IV, Mailisu III and Izbaskent oilfields. These fields produce from Paleogene reservoirs. The Mailisu IV and Izbaskent fields, which were discovered between 1948 and 1972, contained total reserves of 97.5 million barrels (MMbbl) of oil, 45.5 billion cubic feet (Bcf) of associated gas and 323.7Bcf of non-associated gas (all figures in terms of ultimate recovery USGS, 1994) prior to production. Oil in these fields occurs within Paleogene fossiliferous and fractured limestones in anticlinal structures.
A well into one seismic-defined target at East Mailisu in 2009 encountered hydrocarbons, but poor reservoir quality precluded commercial production.
Seismic shot over the East and West Mailisu blocks in mid-2009 is expected to be processed by February 2010.
