Operational Update

Waterflood

During the first quarter the Company continued to expand its waterflood development by both extending the waterflood area through delineation drilling and activating additional waterflood patterns at ECN. As of March 31, 2008, a total of 28 patterns were active injecting a total of 16,700 barrels of water per day compared to 11 active patterns injecting a total of 7,550 barrels of water per day at year-end 2007. Water injection in the ECN field now effectively replaces all of the fluid production from the developed waterflood area. Waterflood response to date has been confirmed in many of the patterns more rapidly than initially anticipated, with time to initial response two to four months ahead of original Company estimates. This favourable trend will be further monitored and analyzed as the majority of the injection patterns at ECN have been on injection for less than six months.

Steamflood

A second steam injection cycle has been completed on wells CoHS-14 and CoHS-15. Information gathered from the first steam injection cycle allowed Petro Andina to optimize both the steam generator performance and wellbore injection operations to ensure that higher quality steam, and therefore more energy, entered the reservoir. Injection behaviour on both wells during the second steam cycle remained as expected and no operational issues related to either injection or formation damage have been identified through two steam injection cycles. CoHS-14 is in the early phases of flow back and the well is reacting as predicted by technical modeling. The production phase of CoHS-15 commenced on March 12th and the oil production from the well has been gradually rising to a rate exceeding 350 bopd at a 10 percent water cut. The "hot oil" production rate is approximately two times the initial production rate of similar conventional producing wells and approximately three times the rate of stabilized conventional producing wells. Steam injection into the third steamflood well, CoHS-16 has commenced and it is expected that a 30-day injection cycle will be completed on this well. A fourth well has been added to the pilot phase so that, after steam injection at CoHS-16 is completed, steam injection will commence into CoHS-4. The Company is currently evaluating the results from the pilot and it is expected that a decision regarding expansion of the pilot project will be made sometime in mid-year 2008.

Pipeline

Pipeline installation operations are now substantially complete. Plans for a drilled crossing were replaced in favour of using a suspended crossing on an existing bridge. Options exist to use or replace an existing line within the current structure as part of the maintenance program or to add an additional deck that would provide for future expansion of the structure. Pre-commissioning work is underway. In parallel with work on the bridge, contractors are finishing modifications to the receiving facility at Repsol-YPF's Puesto Hernandez complex. The 50 percent working interest pipeline will have initial gross capacity of 40,000 bbls/d, enabling it to transport all of Petro Andina's current production, as well as accommodate anticipated production additions.
