Leni spuds seventh Goudron Field well onshore Trinidad

29th October 2014

Leni Gas & Oil (LGO) that well GY-670, the seventh of its planned 30 new development wells at the Goudron Field in Trinidad, and the second well from the third drill pad, was spudded yesterday and is drilling ahead in the Goudron Sandstones at a depth of approximately 220 feet

The final section of the well, which was drilled in 8.5-inch hole, has now been successfully cased to TD and the well is ready for completion as a production well

Well GY-670 is planned to test the Goudron and Gros Morne Sandstone reservoirs to a total depth (TD) of at least 3,100 feet TVDss (equivalent to 3,305 feet measured depth (MD)) and will be deviated approximately 600 feet northwest from the surface location.

"Well seven is now underway and we are analysing the results of well number six, GY-669, which is another successful well with considerable net pay,” said Neil Ritson, LGO's chief executive.

“Reservoir pressures of up to 2,580 psi were measured near TD; the highest we have yet seen, and this may have major benefits for future production from this part of the field."

The sixth new Goudron well, GY-669, reached a TD of 3,505 feet MD and has been electric logged.  The well was drilled to a depth slightly less than prognosed since it was considered that all sand-prone intervals had been penetrated at that location.  The final section of the well, which was drilled in 8.5-inch hole, has now been successfully cased to TD and the well is ready for completion as a production well.

A total of over 400 feet of net hydrocarbon pay have been identified in GY-669.  Analysis of the electric logs is not yet complete however the presence of higher than previously identified reservoir pressure near the base of the well suggests a different fault block has been penetrated than in earlier wells.   Age dating of the intervals penetrated by the well is also on-going in order to ensure the correct identification of the boundary between the Gros Morne and underlying Lower Cruse reservoirs, and the attribution of the identified pay intervals to the appropriate formations.

The completion of GY-669 will be undertaken when Well Services Rig 20 is moved from the drill pad; which is currently anticipated to occur in late 2014.
