Completion design analysis: A case study for water control in Villano field,Ecuador

摘要

Agip Oil Ecuador(AOE)operates Villano field,in a tropical rainforest in Pastaza Province of Ecuador.The field was discovered in 1950 by Shell Global.Production began in May 1999.Since 2000,the field has been operated 100% by AOE.The development was completed in six phases,which included the construction of facilities,flowlines and well pads,and the drilling of production and water disposal wells(WDW).The field produces approximately 12,900 bopd and 204,000 bwpd,which is 100% re-injected.The water disposal is in the Hollin formation,below the oil-water contact.The producing wells are horizontal with 1,500 to 2,500 ft of open-hole length.However,oil production is constrained by the maximum fluid handling capacity.
