London-listed Amerisur Resources has gained full control and operatorship of the Put-8 block in Colombia, writes Julia Martinez.

The company exercised its right of first refusal after joint venture partner Vetra E&P proposed selling its 50% interest in the block, making an estimated $19.1 million acquisition.

The agreement must first be approved by Colombia’s National Hydrocarbons Agency (ANH).

Chief executive John Wardle said the block has been a prime part of the company’s Putumayo portfolio since it acquired Platino Energy in 2016.

The block sits adjacent to Amerisur’s Platanillo field, which hosts the company’s Oleoducto Binacional Amerisur (OBA) area.
