EP Energy Provides Operational Update — Increases Wolfcamp Type Well EUR and Economics

HOUSTON, TEXAS, July 31, 2014—EP Energy Corporation (NYSE:EPE, “EP Energy”) today provided an update on its growing oil programs.

Key highlights include:

·            Increased Wolfcamp Type Well EUR to 450 MBOE, with significant improvement to well economics

·            Ongoing enhancements to completion designs in all three of its oil programs contributed to stronger than expected production growth in 2Q 2014

·            Record oil production of 53.3 thousand barrels per day (MBbls/d) in 2Q 2014 - A 60 percent increase in oil production from 2Q’13 and a 10 percent increase from the first quarter of 2014

“I’m excited to announce we are seeing tangible improvements across all our capital programs” said Brent Smolik, chairman, president, and chief executive officer of EP Energy Corporation.  “We’ve updated our Wolfcamp type well economics as a result of continued improvement in our combined B/C well performance and on-going completion optimization.  In the Eagle Ford and Altamont, recent results from new completion techniques have generated meaningful improvements in production rates that enhance these programs as well.  The single largest driver of higher net asset value for our business is increased efficiencies across our inventory of over 5,600 future drilling locations(1).   It is especially gratifying to see these improvements impact our reported production results.”

(1) As of December 31, 2013 pro forma for 475 drilling locations from the April 2014 acquisition.

Updated Wolfcamp Program

EP Energy has updated the type curve for its entire future drilling inventory of 3,375 Wolfcamp A, B and C drilling locations as summarized below:

(1) Pretax rates based on $90/Bbl (WTI) and $4.50/MMBtu (HH).

(2) As of December 31, 2013 pro forma for 475 drilling locations from the April 2014 acquisition.

Production Volumes Continue to Grow

EP Energy’s net oil production from its continuing operations in the second quarter of 2014 was 53.3 MBbls/d, an increase of 60 percent from the second quarter of 2013 and 10 percent compared to the first quarter of 2014.  All three of the company’s oil programs contributed to the growth.  Production by product is highlighted below:

Note: all information in the table above is from continuing operations.  During the second quarter of 2014, the company reclassified certain of its Arklatex and its South Louisiana Wilcox assets as discontinued and all information above excludes volumes associated with those assets and other assets classified as discontinued operations.

Higher Production Rates

In the Wolfcamp, the updated type curve reflects the results of the combined B/C development and ongoing completion optimization, including tighter frac stage spacing and higher sand concentrations.  This design is expected to generate a pretax NPV that is 43 percent higher than the previous type curve, with a modest 5 percent increase in our estimated well cost.

In the Eagle Ford the company is using enhanced completion designs across its full acreage block, with excellent results and growing oil volumes across its entire position in LaSalle County.  These design changes are not expected to increase per well costs compared to our previously published type well.

In the Altamont field the company is realizing the benefits of optimized well completions and production operations.  During the second quarter the company drilled three of its top 12 all-time wells for a program that dates back to its acquisition in 2001.   These results have been accomplished with well costs equal to, or below, our previously published type well.

EP Energy maintains a $2 billion capital investment budget for 2014, before acquisitions, and remains focused on its three core oil programs in Eagle Ford, Wolfcamp and Altamont.
