Canacol Energy Ltd. Announces Oil Discovery at Oso Pardo 1 Exploration Well in Colombia
The well penetrated the Lisama sandstones as anticipated at 3,390 ft md with good oil and gas shows while drilling, and drilled through the Umir Formation with similarly good oil and gas shows in two separate oil filled sandstone intervals at 3,665 and 3,800 ft md respectively. Petrophysical evaluation of the openhole logs acquired indicate 88 feet of oil pay with these Tertiary sandstones: 60 ft of oil pay within the Lisama sandstones with an average porosity of 25%, and 28 ft of oil pay within two separate Umir sandstones with an average porosity of 16%. However, while drilling the Tertiary section, the Corporation encountered technical problems that compromised the integrity of the wellbore. The appropriate corrective measures were taken but it was decided not to proceed with the drilling of the deeper Cretaceous shales.
Jotain positiivista ja jotain negatiivista. Tiedotteessa ei valitettavasti tarkemmin eritellä ongelmaa.
