2013 Year-End Proved Reserves and Wells Drilled

Jones Energy’s year-end 2013 estimated proved reserves increased 4% from year-end 2012 to 89.0 MMBoe, of which 56% were classified as proved developed reserves. Excluding the 15.5 MMBoe reduction in proved undeveloped reserves resulting from the expiration of the Southridge joint development agreement (JDA), proved reserves increased 23% from year-end 2012, and increased 42% in our core Cleveland area. Oil and NGLs (total liquids) increased to 56% of our proved reserve base. Additionally, proved developed reserves increased by 27% to 49.5 MMBoe.

The following tables set forth the Company’s total proved reserves and the changes in the Company’s total proved reserves. These estimates are based on reports prepared by Cawley, Gillespie & Associates, Inc., independent petroleum engineers. Year-end proved reserves were determined utilizing an average 2013 WTI oil price of $96.78 per barrel and an average 2013 Henry Hub spot market natural gas price of $3.67 per MMBtu.

(1) Includes 15.5 MMBoe associated with the expiration of the Company’s JDA with Southridge in the Woodford.

Excluding non-operated wells, the Company spud a total of 86 gross wells in 2013 and completed 63 gross wells before year-end. As of December 31, 2013, the Company had 22 gross wells in various stages of completion and 10 gross wells drilling. The following table provides a summary of the Company’s 2013 operated drilling and completion activity:

Operations Update

Production Update for the Fourth Quarter of 2013

The Company produced 1.7 MMBoe (approximately 18,200 Boe/d) in the fourth quarter of 2013 and 6.2 MMBoe (approximately 17,000 Boe/d) for calendar year 2013, which was within its guidance range for the year of 6.1 – 6.5 MMBoe (16,600-17,900 Boe/d). The percentage of total production composed of liquids for both the fourth quarter and full year 2013 was 53%. Fourth quarter results were negatively impacted by severe winter weather and frack impacts, including production delays tied to a new completion design tested in the Cleveland formation beginning in late 2013. Winter weather continued to impact production early in the first quarter of 2014, however, all operations have returned to normal and all drilling rigs are currently operating as expected.

Update on Completion Techniques in the Cleveland

Jones Energy has completed 20 test wells in the Cleveland using a new completion technique, which has an average of 20 stages (3 clusters/stage resulting in approximately 70 foot spacing between clusters) compared to the prior design of 20 stages (210 foot spacing). The new technique uses a cased-hole design as compared to an open-hole completion in the prior design. The average cost per well of the new design is approximately $4.0 million, compared to $3.1 million using the historical design. All of the 20 wells in the first phase of the test program have been completed and are currently producing hydrocarbons.

Of the 14 wells with 30 or more days of production, 12 have produced at or above historical type curve. Over the next two quarters, the Company will monitor production data on the test wells and undertake additional optimization techniques, prior to making a decision on whether the level of production is significant enough to justify the incremental capital investment per well, and which design to utilize going forward. In the interim, Jones Energy will be employing its traditional open-hole completion technique in the Cleveland, which is the basis for its guidance for the balance of 2014. Going forward, the Company expects its average Cleveland AFE to remain at a best-in-class $3.1 million, which we expect will allow us to continue to generate compelling rates of return in our core play.

2014 Guidance

Jones Energy is projecting 2014 average daily production of 22,000 – 23,000 Boe/d, which would result in over 30% production growth compared to 2013. We plan to invest approximately $350 million in total capital expenditures in 2014, including approximately $310 million for drilling and completion, and $40 million for leasing, workovers and efficiency projects. The Company’s drilling and completion capital expenditures will be largely funded from operating cash flow.

In order to generate growth above its base plan, Jones expects to begin a three well test in the Tonkawa formation in the second quarter of 2014. The Company has also substantially increased its budget and expectations for leasehold acquisition within its core Panhandle operating area, which is prospective for the Cleveland, Tonkawa and other formations. In addition, we are also conducting frack optimization tests in the Woodford, involving more frack stages (16 – 20 vs. current 10 – 14 stages) with the objective of further improving overall economics in this play. The Company is currently running 10 rigs in its core operating areas (8 rigs in the Cleveland and 2 rigs in the Woodford), however, based on a success case for the Tonkawa drilling or Woodford frack tests, we expect to deploy 2 additional rigs in the second half of 2014.

(1) Company is in ethane rejection in the Woodford. Projections assume ethane rejection continues throughout 2014.
(2) Excluding non-cash compensation expense.
