Goudron Field Update

LGO is pleased to announce that well GY-667 at the Goudron Field in Trinidad has undergone a series of initial production tests after perforating a 44-foot interval in the Lower Cruse Sandstones resulting in a calculated open-hole flow rate of 540 barrels of oil per day ("bopd"). The well is presently producing 40 degree API gravity water-free oil at a rate of 142 bopd through a 7/32-inch choke with a well-head flowing pressure of 420 psi. Higher rates up to over 220 bopd have been successfully tested, however, temporary field-wide production constraints are in place until the additional sales capacity is on-stream in the next week.

Neil Ritson, LGO's Chief Executive, commented:

"The results from GY-667, the Company's first completion in the Lower Cruse reservoir, have far exceeded our initial estimates of 60 bopd. We have yet to confidently locate the thickest zone of Lower Cruse Sandstones and therefore we are excited that a relatively thin interval is producing so prolifically. This is very encouraging for further potential in the Lower Cruse within the field."

The shallower primary Gros Morne reservoir in GY-667, with 219 feet of net oil pay, will be completed for production at a later date.

In addition, LGO confirms that initial production tests have been conducted on GY-666 and GY-668 resulting in a calculated open-hole flow rates of 300 bopd and 330 bopd respectively. Further clean-up work is required on these two wells to optimize flow rates. These wells are currently producing oil with trace water at 34.5 and 29 degree API respectively. Further optimization work will be performed after the new 2,000 barrel sales tank is commissioned.

LGO has now completed the first five of its planned 30 well initial redevelopment at Goudron and the next well, GY-669, is expected to spud imminently.

A summary of the drilling program results to date is given in the Appendix below.

Glossary:

API: American Petroleum Institute

Calculated

open-hole flow rate: A mathematically derived theoretical maximum flow rate that a well could deliver with zero back-pressure at the middle of the perforated interval

pay: A reservoir or portion of a reservoir formation that contains economically producible hydrocarbons. The overall interval in which pay sections occur is the gross pay; the portion of the gross pay that meets specific criteria such as minimum porosity, permeability and hydrocarbon saturation are termed net pay
