SierraCol Energy has interests in the Putumayo basin to carry out exploration activities.

Six blocks:
PUT-8, PUT-9, PUT-36, Mecaya, Terecay and Tacacho.

3D seismic acquisition in the PUT-8 Block was finalised in late April 2021, as well as permitting and socialisation for seismic operations in PUT-9 and Mecaya.

Putumayo

We have exploration interest in six blocks, in association with GeoPark. Our blocks are on trend with the most prolific fields and recent discoveries across the border in the Oriente basin (Ecuador)

Proximity to existing production facilities and evacuation routes, reducing the time to market.

The Putumayo basin is an under-explored area as many discoveries are a one-well field. Structural plays in the basin are very similar to the plays in which important oil accumulations have been found across the border in Ecuador, where there are five giant fields with significant 2P reserves.
