Production Update, Goudron Field

LGO today announces an update on production from the initial work over program at the Goudron Field in south-eastern Trinidad.

Wells GY-190, GY-245 and GY-254 have been successfully worked over and returned to pump production after clean out, removal of accumulated sand and minor repairs. Initial production results fully match expectations with the combined rate from these three wells in excess of 30 barrels of oil per day (bopd). Well GY-245 alone is currently producing at an average rate of 17 bopd. Optimization of the pump configurations is continuing and higher production rates are likely once the work is completed.

The fourth well, GY-63, is presently pumping after being cleaned out and production in the last 24 hours totaled over 40 barrels of oil. A stabilized production rate is expected in the next few days. The final planned well, GY-246, has been entered and bailing of sand to clean the oil producing zone has commenced.

These five wells have been selected to gain practical experience of the field conditions and are part of the larger well intervention program covering approximately 50 wells over the first 12 months of operations. The total cost of the five well program is estimated at US$40,000.

Assignment of the Goudron Incremental Production Service Contract (IPSC) to the LGO wholly owned subsidiary Goudron E&P Limited has been approved in principle by the Trinidad and Tobago State oil company, Petrotrin, and the formal documentation is being processed.

Neil Ritson, LGO's Chief Executive, commented:

"This work over program has gone entirely to plan and confirms our expectation that existing wells will be capable of producing at average rates of at least 10 bopd. After under a month we have been able to raise the production level substantially. Once formal assignment is complete we will embark on the wider program and start planning to drill new state-of-the-art wells."

Competent Person's Statement:

The information contained in this announcement has been reviewed and approved by Neil Ritson, Chief Executive Officer and Director for Leni Gas & Oil Plc who has over 35 years of relevant experience in the oil industry.
