The Rubiales Oil Field is an oil field located in the Llanos Basin, Meta Department, Colombia. It was discovered in 1981 and was first developed, operated and owned by Pacific Rubiales Energy. The field produces heavy oil (11.3-14.5° API gravity) from the C7 unit of the Carbonera Formation.[1] The porosity of the reservoir formation is between 28 and 33% and the permeability ranges from 3 to 5 Darcies.[2] In 2008, 22.817.163 barrels were produced from the field.[3] The total proven reserves of the Rubiales oil field are 4.38 billion barrels (588×106tonnes), and production in 2017 is 132,000 barrels per day (21,000 m3/d).[4]
