Amerisur Resources plc (OTCMKTS: ASUXF) is a London-based upstream oil and gas exploration and production company with a portfolio of onshore assets in Colombia’s highly prospective Llanos basin. The company focuses on the identification, appraisal and development of oil prospects and fields, and holds interests in several licences that span both the Guama and Quifa areas. Amerisur’s business model centers on delivering sustainable production growth through measured field development and disciplined capital allocation.
Amerisur’s core operations are located in eastern Colombia, where its flagship Gibraltar oil field commenced production in 2015. The company also holds interests in satellite discoveries such as Achala Norte and Cravo Este, enabling it to leverage existing infrastructure to fast-track production from new reservoirs. Crude oil is sold under multi-year offtake agreements to regional refiners and exporters, providing stable cash flow to support ongoing exploration activities.
Since its founding in 2005, Amerisur has grown through strategic acreage acquisitions, farm-in agreements with major energy companies and the application of advanced seismic and drilling technologies. This growth has been underpinned by partnerships with local service providers and a commitment to operating safely and responsibly in sensitive environments. Over the years, Amerisur has invested in community engagement, infrastructure improvements and environmental management programs to strengthen its social licence to operate in Colombia.
Amerisur is led by an experienced management team and board of directors with deep expertise in Latin American upstream oil and gas markets. Under the guidance of Executive Chairman Tim Wetheridge and the senior leadership group based in London and Bogota, the company continues to pursue value-accretive exploration prospects, optimize production performance and unlock further resource potential across its Colombian asset base.
