This paper submits the monitoring methodology applied to horizontal wells associated to the First polymerized water injection pilot project, developed in Zuata Principal Field from Hugo Chavez Orinoco Oil Belt (Venezuela). Zuata Principal is a mature field of unconsolidated sands of deltaic and fluvial sedimentary environments, saturated with extra heavy crude of API gravity between 8.5 to 9.5, and viscosities between 2000 to 5000 cp at reservoir conditions. The basic units of production construction (Clusters) are mostly made of horizontal wells perforated in a radial pattern, which operate under the artificial lifting method of progressive cavity pump (PCP). The pilot project was developed in a deltaic environment.
