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.
