The Ogarrio oil field, a mature onshore oil field located in the state of Tabasco in Mexico, is undergoing a $450m expansion to increase its production capacity by 30%.

The expansion project is being jointly carried out by Deutsche Erode (DEA) and Pemex. DEA was granted 50% license share as well as the operatorship of the Ogarrio oil field by the Mexican National Hydrocarbons Commission (CNH) in a 25-year farm-out agreement in October 2017.

The remaining 50% ownership of the oil field is held by Pemex.

The contract license agreement for the Ogarrio oil field development was officially signed between CNH, DEA, and Pemex in March 2018.

Ogarrio oil field location and site details

The Ogarrio oil field is located 107km west of Villahermosa in the state of Tabasco, Mexico, and covers a surface area of 156km².

The onshore oil field is situated in the Pilar Reforma-Akal geological province within the Southeast Basin of Mexico.

Ogarrio oil field discovery and reserves

Discovered in 1957, the Ogarrio oil field was developed with more than 527 wells, out of which approximately 100 are currently active.The field is estimated to contain 54 million barrels of oil-equivalent (Mboe) of proved reserves.

The main reservoirs of the field comprise Miocene and Pliocene rocks of Neogene Paleogene ages. The average reservoir depth of the field is 2,600m.

The oil resources of the Ogarrio field have an API gravity of 37° and are classified as high-quality light crude oil.

The field also contains gas resources, which were estimated to be 1.16 billion cubic feet (bcf).

Ogarrio oil field expansion details

The 100 active wells on the Ogarrio field are currently capable of producing 12,500boe of hydrocarbon resources a day, including 7,700 barrels of oil and 29 million cubic feet (mcf) of gas a day. The expansion will expand the field’s production capacity by 30%.

The already existing wells will undergo an extensive workover campaign, while ten new wells are planned to be drilled, as part of the expansion project.

The workover campaign will involve the replacement of certain existing wells with fresh well completions for increased oil  production.

Secondary oil recovery technique involving water flooding and gas injection in one part of the field will be also employed to enhance oil recovery from the ageing field.

DEA plans to complete a technical feasibility study for water flooding as well as the drilling of new production wells at the Ogarrio field by 2020.

The Ogarrio field produced 10,000boed of oil and gas in March 2018, which is expected to be increased to 13,000boed by 2020.
