Curzon Energy Plc announced that workover and clean-out operations have been completed on all five existing wells, which form part of the Phase I development plan, located in the north-west area of the Coos Bay licence acreage. Workover and clean-out operations have been completed on all five existing wells (1-21, 9-21, 15-21, 13-15 and 16-16); Outcomes so far from the workover operations completely correlate with the technical analysis conducted by Curzon in advance of this five well workover programme; Workover operations have removed sand and coal fines in each of the five wellbores; Removal of approximately 120 ft of old pump rods and 180 ft of old tubing from the bottom of well 13-15 during a fishing operation; Upgrading of existing surface infrastructure and testing equipment completed; Extensive well testing to commence shortly; Remain on track to deliver first gas in second quarter of 2018. Following evaluation of this work programme, the company believes that well bore obstructions due to the presence of sand, coal and debris, may have created flow restrictions, in particular from deeper pay completions, resulting in historic test rates below the actual potential of these wells. In parallel with the workover operations, the company has upgraded existing surface infrastructure and testing equipment in advance of an extensive testing programme that will commence shortly in order to determine commercial viability of the CBM Project and optimise a field-wide development plan as part of a larger Phase II commercialisation.
