ELECTRIC SUBMERSIBLE PUMPS INSTALLED IN SHIELD WELLS AT BIBBLEWINDI MULTILATERAL PILOT Electric submersible pumps (ESPs) were installed in the build section of the shield wells at each side of the Bibblewindi multi-lateral pilot. The build section of the well is the curved section ahead of the lateral well drilled through the target coal seam to intersect the vertical production well. This initiative took early advantage of advancements in ESP design that have improved potential for use of ESP technology in coal seam gas applications. By year end, the additional dewatering capability associated with installation of the ESPs contributed to gas production from the Bibblewindi multi-lateral pilot exceeding 1.5 million cubic feet per day. It is anticipated the gas production rate will continue to climb as water pressure within the Bohena coal seam is progressively brought down from present levels of around 500 metres of head. ● SEISMIC ACQUISITION The Company has received approval for an 88 kilometre seismic survey within the Narrabri Gas Project area, the purpose of which is to: ● provide infill data linking vintage seismic lines to the north and south of the Rosevale area so that drilling opportunities can be firmed up; and ● investigate Permian sedimentary development in the northwestern region of PEL 238. The seismic survey will take place in conjunction with surveys approved for other acreage operated by the Company. Although requisite Government approvals have been secured for the surveys, a final commitment by the Company to undertake work has been delayed while cooperative arrangements are agreed with Local Government and communities. ● DEWHURST PRODUCTION PILOT The Dewhurst lateral production pilot incorporates three parallel lateral wells, each intersecting a single vertical production well and all targeting the Bohena coal seam. Two production wells were operated for a short period during the financial year to collect data for design of an on-site water storage facility. After construction of the water storage facility the Dewhurst Pilot will be operated on a temporary basis to confirm overall water and gas production profiles. Temporary operation will provide data sufficient for gas reserves certification purposes.
This is our reserves upgrade which will be released as part of the independent reserves review in the IER and which Monsters highlighted from the November 2010 announcement...
Now, there is an outside chance, there will be an additional update from Tintsfield in the IER however this is unlikely in the absence of another bidder imo.
