Petrominerales Ltd. (PMGC), the Calgary-based oil producer with most of its operations in Colombia, rose the most in eight weeks after saying it was able to produce oil from a test well.
The shares advanced 10 percent to 11,280 pesos at 1:17 p.m. in Bogota, set for the biggest gain since June 18. It was the biggest advance on the Colcap equity index, which was little changed.
Petrominerales said in a statement today that a test of its Taya-1 well produced 5,218 barrels of oil per day.
The oil explorer has lost 23 percent this year, the biggest decline on the Colcap.
