Warren Resources Announces 2014 Production, Updated 2015

• Production increased 77% year-over-year in 2014
• 2015 Capital Budget reduced to approximately $21 million

NEW YORK, Jan. 26, 2015 (GLOBE NEWSWIRE) -- Warren Resources, Inc. (Nasdaq: WRES ) today announced expected total production volumes for the full year 2014 and updated its capital budget and production guidance for the full year 2015.

While year-end audited financials are not yet complete, Warren estimates production for the full year 2014 grew 77% year-over-year to approximately 22.8 billion cubic feet of equivalent ("Bcfe"), approximately 70% of which is natural gas. This production growth is primarily attributable to increased volumes resulting from the acquisition of the Marcellus assets in the third quarter of 2014.

With the ongoing volatility in commodity and capital markets, Warren is revising its 2015 capital budget lower to approximately $21 million from the Company's preliminary $80 million budget released in early December 2014.

The Company is now budgeting $13 million in the Marcellus to drill and complete two Upper Marcellus wells in 2015 and for associated facilities. Drilling was completed on the first Upper Marcellus well, the Mirabelli 11H, in late January in the northeast portion of the Company's acreage position and completion operations are expected to commence in early March. The second well, the Ruark 11H, is planned in the center of the acreage block, with completion operations expected to commence in early May. Completion operations on two lower Marcellus wells were concluded in January, with initial production expected in mid-February.

In addition, Warren has reduced its facilities and infrastructure budget in California to $8 million and suspended CBM drilling and completion activity in Wyoming, eliminating approximately $20 million of capital previously allocated to that program. As mandated by federal permit restrictions and lease stipulations, drilling on federal lands in the Atlantic Rim, where the bulk of Warren's 2015 program was planned, cannot commence until after August 1 ^st . Therefore, Warren has ample time until then to re-evaluate the decision to suspend activity should conditions improve.

Warren is updating its full year 2015 production guidance to reflect the reduction in planned drilling and completion activity. For the full year 2015, Warren expects total production volumes to range between approximately 33 Bcfe to 36 Bcfe, a projected 52% increase over 2014, at the midpoint. Warren expects natural gas volumes to comprise approximately 84% of total production in 2015.

"The revised 2015 budget reflects the flexibility Warren has as operator of essentially all of its assets, enabling the Company to adjust development activity to account for fluctuations in the commodity price environment," said Lance Peterson, Interim CEO. "The reduction in capital expenditures in conjunction with a strong asset base, where approximately half of Warren's reserves are in long-life waterflood and CBM assets, positions the Company well to ride out the current commodity price volatility and return to growth when conditions stabilize. Even with reduced drilling and completion activity in 2015, the two Upper Marcellus wells planned for this year offer the opportunity to prove-up the formation and add reserves organically."
