Poplar CO2-EOR Update

DENVER, CO -- (Marketwired) -- 09/22/14 -- Magellan Petroleum Corporation ("Magellan" or the "Company") (NASDAQ: MPET) today provided an update on the status of the Company's CO2-enhanced oil recovery ("CO2-EOR") pilot (the "Pilot") at Poplar Dome. 

The Company has been continuously injecting volumes of CO2 into the B-2 zone of the Charles Formation through the EPU 202-IW well (the "Injector Well") since August 29, 2014. Since then, downhole pressure in the Injector Well has remained stable and above the minimum miscibility level, which is the minimum pressure necessary for CO2 to become soluble in oil and thereby aid in the recovery of additional oil volumes. 

J. Thomas Wilson, President and CEO of Magellan, commented, "Though preliminary, these results are in line with our understanding that CO2-EOR is viable at Poplar. Our ability to inject CO2 in the reservoir and maintain pressure above the minimum miscibility level is very encouraging and potentially indicative that (i) CO2 is beginning to sweep oil out of the reservoir; (ii) the injected volumes of CO2 are not escaping through fractures or 'thief zones'; and (iii) in a full-field development scenario, the field will not have to be significantly re-pressurized to achieve minimum miscibility, potentially resulting in substantial time and cost savings relative to other CO2-EOR projects. As we continue to inject CO2, we expect to gain a greater understanding of the potential incremental oil volumes that CO2-EOR could yield. I look forward to updating shareholders regularly on the progress."

The Company plans to continue the continuous injection of CO2 into the B-2 zone through at least the first quarter of calendar 2015, when the Company expects to be in a position to quantify incremental recoverable volumes of oil from this zone. Thereafter, the Company will begin the evaluation of CO2-EOR on other zones in the Charles Formation, including the B-1 and A zones. During the fourth quarter of calendar 2014, the Company plans to open the four producer wells for production. The initial primary production from these wells will provide a baseline against which the Company can measure the impact on production of CO2 injection.

The Company began initial CO2 injection through the Injector Well in March 2014 and then paused injection during the spring and summer to optimize well completion and surface facility design. For further detail on developments related to the Pilot since March 2014, please see the description of the Pilot in the Management Discussion and Analysis section of the Company's fiscal year 2014 annual report filed on Form 10-K with the U.S. Securities and Exchange Commission on September 18, 2014.
