Alberta Energy Regulator Approves Application for HCSS Demonstration Project on Deep Well’s Lands

EDMONTON, ALBERTA–(Marketwired – Aug. 27, 2013) – Deep Well Oil & Gas, Inc. (and its subsidiaries Northern Alberta Oil Ltd. and Deep Well Oil & Gas, Inc. – “Deep Well” or “Company”) (OTCQB:DWOG) is pleased to announce that the Alberta Energy Regulator (“AER”, formerly known as the Energy Resources Conservation Board or ERCB) has approved an application previously submitted by the Company to the AER for development using Horizontal Cyclical Steam Stimulation (“HCSS”), planned for the thermal recovery project on one half section of land located at section 10-92-13W5 near Sawn Lake, Alberta. This approval is related to lands presently owned 90% by Deep Well. MP West Canada SAS, a wholly owned subsidiary of Saint-Aubin Energy (owned 1/3 by Maurel et Prom and 2/3 by MPI, two listed companies based in Paris, France), in addition to the previously announced SAGD project, has the option to participate for up to a 45% working interest in this HCSS project by committing an additional US$110,000,000 of funding.

In September of 2009, Deep Well applied to the AER for a commercial bitumen recovery scheme to evaluate one of our wells for potential development using cyclical steam stimulation (“CSS”) on one of our vertical wells. In October of 2010, this application was approved by the AER. In February 2012, Deep Well filed an application with the AER to modify its previously approved CSS application to use an HCSS recovery process instead of vertical well CSS.

The modification of Deep Well’s production plan arose from reservoir modeling by DeGolyer and MacNaughton Canada (“D&M”). These models showed the results of thermal recovery using Horizontal CSS optimized the recovery factors for certain areas of Deep Well’s reservoir.

This AER approval for Deep Well’s planned thermal recovery project near Sawn Lake on one half section of land located at section 10-92-13W5 is the approval that was needed before significant work could begin.
