Sundance Energy Australia Limited Provides Operations Update

DENVER, June 28, 2017 -- Sundance Energy Australia Limited (ASX:SEA) (NASDAQ:SNDE) (“Sundance” or the “Company”), a U.S. onshore oil and gas exploration and production company focused in the Eagle Ford in South Texas, reported initial production rates on its four operated  Eagle Ford wells that have begun production in the second quarter.

Grace Ford, COO, commented “we are very pleased with early results from our 2017 development program.  Our generation 5 completion design which focuses on perforation proficiency is generating higher initial production rates which we believe will translate to higher ultimate recoveries and better economics.  In addition to higher production rates, the two new Dimmit wells we brought online saw first oil approximately 30 days earlier than previous wells.  While we have seen some delays caused by tightening in the onshore US service market, so far we have been able to offset these minor delays with improved well results.”

The Company recently acquired approximately 3,200 net acres in its core McMullen area for $5.8 million adding approximately 21 gross (19 net) lower-lower Eagle Ford (“LLEF”) locations and 17 gross (16 net) upper-lower Eagle Ford (“ULEF”) locations.  The new additions bring the Company’s McMullen area LLEF inventory to 128 gross (107 net) remaining locations and its ULEF inventory to 149 gross (126 net) remaining locations.  Approximately 17 of these new locations are considered to be proved reserves adding approximately 6.5 mmboe to our proved reserve base.  To fund the lease acquisitions we have deferred drilling one well.

Eric McCrady, CEO, commented “we are very excited to build our McMullen area drilling inventory with these lease additions in our core project area which are contiguous with our existing acreage position.  At an average price of ~$1,900 per acre we have replaced the locations we are drilling as part of our 2017 development program and extended our inventory.  We anticipate the proved component of these leases will add over $40 million to our proved PV10 based on 1 June 2017 NYMEX strip oil prices.”
