Canacol Energy has made a discovery in the Chontaduro 1 well, its second gas discovery in recent weeks in Colombia’s Lower Magdalena Basin.
The exploration well was drilled to a total depth of 9,625ft and contained 123ft of true vertical depth of net gas pay zone with an average porosity of 21% in the primary Cienaga de Oro (CDO) sandstone reservoir, Canacol said in a press statement.

The company said: “The CDO reservoir was perforated over a 279ft MD Interval and the well tied into the Jobo gas treatment facility. The well started at a production rate of five million standard cubic feet per day (MMscfpd) for two hours at a choke 29/128” and a THP (tubing hanger pressure) of 2,290psi (ponds per square inch).
“The rate was increased to 8MMscfpd for another two hours with the choke at 30/128. The rate was increased increments of 1MMscfpd over a period of five hours and the choke until it reached 12MMscfpd. The choke at the final rate was 36/128 and a THP of 2,260psi. The well continues to produce at a rate of 12MMscfpd over the past 29 hours with a stabilised THP of 2,260psi,” it added.
The wells sit in the VIM21 exploration and production contract, which is wholly owned by Canacol. The contract covers 27,410 acres.
In March 2024, Canacol made the Pomelo 1 discovery in VIM21. The well was drilled to a total depth of 12,276ft and has an average porosity of 21% in the primary CDO sandstone reservoir. Last year, Canacol also made the Lulo gas discovery. This was drilled to a total depth of 8,434 ft and 207ft of net pay zone gas was discovered.
