The La Cira Infantas fields have attractive reservoir and fluid characteristics with an average formation depth of 2,900 ft, average porosity of 22%, average permeability of 1.370 mD, and recovery factor of approximately 22% – with plenty of running room.
The Middle Magdalena assets have five major production facilities and over 1,600 active wells.
Middle Magdalena
La Cira Infantas is the oldest and among the best understood clusters of fields in Colombia. It has been in production since 1918, with a total historical cumulative production of approximately 900 mmboe.
La Cira Infantas Field is a large scale waterflood, enhanced oil recovery project. In the area we also operate the Bolívar licence, in which we hold 100% WI

In La Cira Infantas our focus has been on water injection selectivity to increase production, while in Teca-Cocorná cyclic steam stimulations have been maintained, exceeding production targets.
In addition, we are evaluating opportunities and assessing best strategies for development plans in the Bolívar Block.
Oil from La Cira Infantas is sold to the Barrancabermeja refinery, which is designed to operate with crude oil based on production quality similar to our La Cira Infantas production, making our crude a first choice for the refining operation.
La Cira infantas
The La Cira Infantas field is located in the Middle Magdalena basin; the block includes two fields: La Cira and Infantas, corresponding to two structural closures with La Cira being located to the north and Infantas to the south of the block. The Infantas field was the first oil field discovered in Colombia in 1918, followed by La Cira a few years later.
La Cira Infantas is the largest field in Colombia with a total OOIP of 5,257 mmboe and cumulative production of around 900 mmboe.

SierraCol Energy and its partner Ecopetrol are carrying out an enhanced recovery project in La Cira Infantas. Since 2009, wehave conducted an intensive drilling campaign with more than 1,300 wells drilled.

The field complex is a faulted anticline cut by a Paleocene-Eocene age east verging system of thrust faults known as the Infantas thrust. Established production is confined to the footwall closure (west) side of the Infantas thrust in Eocene to Miocene age fluvial-lacustrine sands of the Esmeraldas, Mugrosa and Colorado formations. The field is approximately 12 miles long by 4.5 miles wide.
In addition, the Infantas East field was discovered in 2017. We are currently delineating the accumulation and acquiring additional information for the development plan.
Teca-Cocorná
The Teca-Cocorná contract is located in the west of the Middle Magdalena basin (Middle Magdalena heavy oil belt), approximately 70 miles south of the Barrancabermeja Refinery. The field was discovered in 1963. Productive intervals are fluvial, Miocene aged sands hosting 12° API oil.

Since 2018, drilling activity has been performed in the field to test the concept of continuing steam stimulation in the A&B sands.
Bolívar
SierraCol Energy operates the Bolívar contract, which covers 20,300 acres.
It includes the Catalina field that was originally discovered in the 1950s and then partially redeveloped in the late 1990s, but that is currently inactive. The Catalina field has two proven reservoir levels, and we are planning to reactivate this field.
SierraCol Energy holds 100% of the interests in this block.
