Commentary

The introduction of ANH and de-escalation in the conflict with FARC should have kickstarted exploration, but concerns on the licencing process has been a significant headwind.

Lower Magdelena

Description

The LMB was principally formed during the Campanian, following the collision of the northeast-migrating Farallon plate and a subduction zone developed beneath Colombia uplifting the Central Cordillera, producing east-directed thrusting and a foreland basin. Subsidence resumed in the Mid-Late Eocene and the thrust front advanced eastward through the LMB region. The LMB was first isolated during the Mid-Late Eocene-Miocene during uplift of the Eastern Cordillera, producing west-directed thrusting and reactivation of the Central Cordillera structures. Antithetic sinistral faults which are parallel to the Santa Maria fault have not been documented but may account for the sinistral offsets observed between the Middle Magdelena Basin and the LMB.

Summary

The Basin has been extensively explored, although new discoveries continue to be made leveraging modern technology.
