The stock of Calgary-based Solana Resources slid slightly Thursday despite the company reporting “exceptional” test results at its first Los Aceites well in Colombia’s Llanos Basin.

The Los Aceites-1 exploration well flowed on average over 5,000 barrels of 40-degree API oil per day from 10 feet of well perforations, the company said.

Solana’s net of 2,800 bpd was given context by acompany statement about Colombian oilfields: “Llanos Basin fields,in Solana's experience, are usually characterized by limited reserves, high initial production rates (500 bpd to 2,000 bpd) and quickly increasing water cuts.”

The good test means the compamny will now “revisit” the mapping of the Los Aceites prospect with a view to establishing potential field limits. Another well may be in order.

The Guachiria block is subject to a 13 percent royalty with Ecopetrol S.A. above what the government gets.
