The El Salto field, located in Venezuela's Monagas state, covers an area of 475 square kilometers. It is operated by Petrodelta, a joint venture between state-owned firm PDVSA (60%), Houston-based company Harvest Natural Resources (20.5%), local firm Vinccler (8%) and Argentina's Pluspetrol (11.6%). The project contains reserves of 110Mb of oil and 39Bf3 of gas, while 3P reserves are estimated at 690Mb of oil and 185Bf3 of gas. The field was discovered in 1936, but it was not until 2003 that it was the subject of an evaluation by Harvest. In 2006, a final agreement to form Petrodelta was signed. Since 2009, the field has been at a development stage and more than 29 wells have been drilled. based on information from January 2014, there are 23 productive wells in the field which produce about 21,000b/d. It is believed that the field has more geological structures that have not yet been explored. As a result, future plans include building more infrastructure to fully develop the asset.
