Range has announced that the QUN 160 development well in Trinidad that spudded on 9 November 2016 was successfully drilled to a total depth of 2140 ft on 22 November 2016. The well was originally planned to be drilled to 2600 ft, however it was decided not to drill below 2140 ft as the main target (Upper Cruse formation) had been encountered at this depth and drilling of the additional footage would have contributed to an increase in drilling cost with little to no benefit.
During drilling, hydrocarbon sands and oil shows were encountered between 1084 and 2045 ft. The production testing is expected to commence at the beginning of December and is proposed to be completed in two stages, at depths between 1012 to 1271 ft (Lower Forest formation, stage 2) and between 1794 to 1963 ft (Upper Cruse formation, stage 1).
Range has also advised that the GY 218 SE well (renamed GY 681 well) located in the Beach Marcelle field successfully spudded on 1 December 2016. The well is drilling ahead to a total depth of 4500 ft, expected to take approximately four weeks to reach target depth. The primary target of the well is the Lower Gros Morne formation located below 3500 ft. Any success with the well is expected to open up other development opportunities for that reservoir and add to the geological knowledge of the area.
The GY 681 well is the last well from the five-well campaign to be drilled this year. The well is being drilled by RRDSL* using the 2000 m rig, which has been granted all necessary regulatory and government approvals in November 2016.
