Project Profile
Location: South-eastern Trinidad, Trinidad and Tobago
Reserves: 805 mmbbls oil in place (2015)
Peak Production: 100 barrels of oil per day (2012 target)
Leni Gas & Oil proceed with the mobilisation of a workover rig to commence field operations on the re-development of the onshore Goudron field in south-eastern Trinidad through its wholly owned subsidiary Goudron E&P Limited (GEPL). The company plans to re-develop the Goudron oilfield in partnership with Petrotrin under the terms of an existing Incremental Production Service Contract (IPSC). Re-development will start with the working over of up to 50 existing wells and will be followed by the drilling of additional wells, the application of new technologies and ultimately through a water flood program. Petrotrin have now granted conditional approval to the assignment of the IPSC and LGO plans to commence field operations imminently. In September 2015, it was proved that the shallow Goudron Sandstone reservoir holds an estimated 343 million barrels (\"mmbbls\") of gross oil in place and represents over 40% of the overall current Goudron Field\'s estimated gross 805 mmbbls oil in place.
The Goudron Field lies between the East Moruga and Beach Marcelle fields in south-eastern Trinidad and has direct access to the Petrotrin oil export pipeline to the Pointe-a-Pierre refinery in western Trinidad. The oil reservoirs generally lie between 300 and 3,500 feet below surface and the oil is low sulphur and has API gravities ranging between 25 and 55 degrees. GOR is variable but generally higher in the deeper Gros Morne (Cruse equivalent) reservoir zones and lower in the overlying Goudron Sandstones. Proven reserves, recoverable using existing wells and a small number of infill wells were initially estimated, by Sorgenia International. Additional possible recoverable reserves have been attributed to hydraulically fractured wells and contingent resources are also attributed to a future potential water flood scheme. LGO has assessed the opportunity for an initial work-over program aimed at improving the production from existing wells and estimates that production can be raised to 400-500 bopd. A work over rig from Altech Services Limited is being mobilised to the field now and is expected to commence operations within May 2012.
