The studied Abu Dhabi onshore field, characterized by over 60 producing horizontal wells, has undergone extensive hydrocarbon recovery through miscible techniques for more than 15 years. The field’s recent expansion includes delineation wells drilled to appraise potentially separate oil pools to the west and confirm structural integrity and reservoir continuity. This study leverages oil-fingerprinting technology and geochemical data to evaluate fluid connectivity between the main field and stepout wells.
Field Background
The main field’s horizontal-well production is assisted by water-alternating-gas (WAG), CO2-WAG, and CO2 enhanced oil recovery. The WAG has been operational for 15 years.
