Bass Oil Limited provided an update on its recent production optimisation program. Bass mobilised a wireline unit to the Company's Worrior and Padulla fields in late November to perform a series of low-cost zone changes and pump refurbishments. As a result of that program production has increased 30% from 80 bopd to 105 bopd. Worrior production optimisation program: The wireline intervention program consisted of retrieving and refurbishing the jet pumps in Worrior wells 4, 5 and 7 and Padulla wells 2 and 3. The production increase to its currently level of 105 bopd was recorded when these wells were returned to production and the processing facility stabilised. Worrior Jet Pump expansion: The Worrior field has only one pump providing power fluid to the jet-pumped wells at present. As a result, only three wells, Worrior's 4, 5 and 7 have been on pump. The remainder, wells 2 and 6
are on natural flow. Existing infrastructure at the Worrior facility can accommodate up to three pumps operating in parallel to provide power fluid to increase production from the wells. Bass is planning to recommission a second pump as soon as replacement parts become available from the supplier. This additional power fluid will be deployed to return the remaining wells to artificial lift which should result in a further increase in production. Worrior workover program: Bass is planning a two well workover program scheduled to commence in late January 2023, the current timing is based on Workover Rig availability. The first, is a workover of the Worrior 11 well to return it to production. The well is currently shut- in. Bass previously identified attic oil potential in the McKinlay zone in this well that has never been produced. This zone is assessed as capable of delivering 200 to 300 bopd initial production on pump. The second workover will be performed on Worrior 8 to repair a suspected tubing leak. The well is also currently shut in. The well will then be returned to production.
