The Company is pleased to provide an update on the results of the production testing following almost six weeks of operation. This production testing at Nyanda-4 is the first production test of the Reid's Dome Beds within (and in the region of) PL 231.
As advised, dewatering commenced on
Along with the early success at Nyanda-4, further recent successes at both Aldinga East-1A and Serocold-1 have led the Company to commence planning for this year's pilot testing program.
To this end the Company has engaged
The results of this exercise reconfirmed that gas flow rates have been very positive and increased steadily as the water level in the well has been reduced, although rates were previously overstated.
As at
The water level in the well continues to be slowly lowered and gas flows continue to increase in a linear trend as dewatering progresses. Currently at 702 m from surface, the fluid level remains above the level of the lower coals and sands in the well, and further increases in the gas flow rate are therefore expected. Total depth of Nyanda-4 is 1,200 m.
The volumes of water produced from the well continue to be at the lowest end of the range of water production from coal seam gas wells, indicating a minimal water management task.
Given these exceptionally high flow rates for a well that is not aided in de-watering with a sentinel well and has only been in production for less than 6 weeks, the Company will be designing this year's programme to maximise the geographical extent of the
The audit confirmed that, apart from the calibration of the Nyanda-4 meter, all other results remain unamended.
In other news, workover activities to complete the Serocold-1 well have been finalised, and surface facilities for the production test are now being installed. It is anticipated that the production test of the well will commence by the beginning of next week.
Further updates will be provided as further results become available during the coming weeks.
