The company encountered an oil column of about 149 meters with about 48 meters of net pay in the Albian section and a column of 59 meters with net pay of 23 meters in the Aptian section, both in carbonate reservoirs.

The drilling of the OGX-31 well, also known as the Osorno prospect, was concluded at a final depth of 3,786 meters.
