The choke size has been reduced over this period from 19/64ths to 14/64ths to maintain a wellhead pressure of about 60psi. There has been no evidence of water production to date, according to Impress.

“The purpose of the test is to gain knowledge of the production characteristics of the Mirage Field, to assist in determining ultimate reserves and help in placement of development wells,” the company said.

“The results to date, although early in the test, are encouraging. The well would produce significantly more under artificial lift but the test is being undertaken under controlled parameters to gain the best data to enable efficient development of the field and accurate reserve estimations.”

The partners now plan to spud a Mirage-2 well in July.

Meanwhile operator Victoria Petroleum is sourcing the necessary pump and tank equipment to enable the Ventura well – located elsewhere in the same permit – to be placed on production. Refurbishment of a pump is currently underway and the well should start producing in about 30 days, Impress said.

Partners in PEL 115 are Victoria Petroleum (operator) 40%, Roma Petroleum 20%, Impress Ventures 15%, Entek Energy 12.5%, and Tacnas Pty Ltd 12.5%.
