Successful appraisal of Canacol’s Oso Pardo light oil discovery

Canacol Energy Ltd has announced the successful appraisal of the Oso Pardo light oil discovery made by Canacol in 2013 with the Morsa 1 well located on its operated Santa Isabel Exploration and Production Contract in the Middle Magdalena Basin of Colombia, which production tested 832 bpd of light oil.

2014 drilling programme

Charle Gamba, President and CEO of the Corporation, commented "Our drilling programme continues to deliver in 2014, with Morsa 1 marking the successful appraisal of the Oso Pardo light oil discovery that we made within Tertiary aged sandstones on the Canacol operated Santa Isabel contract in 2013. The Corporation also made an important Tertiary sandstone oil discovery at Mono Arana on the VMM2 contract located next door in 2013, and these consecutive oil discoveries prove up a very promising shallow light oil play within the Tertiary sandstones on these blocks that we are aggressively appraising and bringing onto production throughout the remainder of calendar 2014 and 2015. Our assets in the Middle Magdalena Basin are contributing meaningful low decline light oil production and reserves growth to the Corporations diverse portfolio in Colombia. Canacol currently has 6 rigs under contract and is drilling the Pointer 1 oil exploration well on the LLA23 contract in the Llanos Basin, the Palmer 1 gas exploration well on the Esperanza contract in the Lower Magdalena Basin, and development and appraisal wells in the producing Pantro, Capella, and Libertador oil fields located in the Llanos, Caguan - Putumayo, and Oriente Basins respectively."

Morsa 1 well and test results

The Morsa 1 well was spud on 27 May 2014 and reached a total depth of 5944 ft measured depth (ft md) on 19 June 2014 with good oil and gas shows encountered while drilling through the primary Umir sandstone reservoir target. The well encountered a total of 66 ft of net oil pay in 2 separate sandstone reservoirs within the Tertiary Umir Formation with an average porosity of 17%.

The Umir reservoir was perforated from 3504 to 3725 ft md and is currently flowing at a gross rate of 832 bpd of 25° API oil with 0.1% water cut and 160 000 ft³/d of gas using a progressive cavity pump (PCP) over the course of a 9 day flow period.

Santa Isabel E&P Contract: rigging up at Oso Pardo-1.

Forward plans on Santa Isabel

Upon completion of the production test at Morsa 1 the corporation plans to leave the well on long-term production test from the Umir sandstone, subject to the approval of the Agencia Nacional de Hidrocarburos. The rig will spud the Oso Pardo 2 well, designed to test the southwestern extent of the Umir discovery, in the last week of July 2014. Upon the completion of the drilling and testing of the Oso Pardo 2 well, which will take approximately 3 weeks, the corporation plans to use the drilling rig to do a remediation and install a PCP into the Oso Pardo 1 discovery well which was damaged while drilling in order to increase its production rate to levels similar to the Morsa 1 well. The Oso Pardo 1 discovery well has been on long-term production test since September 2013, and in its damaged state is currently producing 120 bpd and 27 000 ft³/d using a jet pump.

Canacol Energy Ltd aims to release more information as and when it is available.
