Sanchez Energy Announces Fourth Quarter and Full Year 2017 Operating Results; Reports 88 Percent Increase in Year-End Proved Reserves; Announces Successful Four Bench Development in Eagle Ford
February 1, 2018 at 7:01 AM EST

HOUSTON, Feb. 01, 2018 (GLOBE NEWSWIRE) -- Sanchez Energy Corporation (NYSE:SN) (“Sanchez Energy” or the “Company”) today announced year-end 2017 proved reserves and operating results for the fourth quarter and full year 2017.  Highlights include:

  • Proved reserves increased by 88 percent during the year to approximately 363 MMBoe, with a reserve replacement ratio of roughly 762 percent in 2017;
  • Fourth quarter 2017 production of nearly 7.5 million barrels of oil equivalent (“MMBoe”), or 81,977 barrels of oil equivalent per day (“Boe/d”), approximately the midpoint of the Company’s 80,000 Boe/d to 84,000 Boe/d guidance for the quarter;
  • Full year 2017 production was approximately 25.7 MMBoe, or 70,320 Boe/d;
  • The Company’s year-end Comanche drilling inventory increased by approximately 800 gross locations through staggered development of the Lower Eagle Ford;
  • A four-zone stack development test of 17 wells was completed at Briscoe Catarina South, in Comanche Area 3, with average per well 30-day initial production rates of approximately 1,252 Boe/d from the two Lower Eagle Ford zones and 675 Boe/d from the two Upper Eagle Ford zones;  
  • The success of the stacked development test at Briscoe Catarina South confirms the Company’s thesis of up to four economic targets in parts of the Comanche acreage; 
  • The Company brought a four well pad on-line at Chupadera Ranch, of Comanche Area 7, that showed Lower Eagle Ford A and Lower Eagle Ford B zones outperforming expectations with an average 30-day initial production rate of approximately 640 Boe/d, 50 percent of which was oil;
  • The success of the Chupadera Ranch wells helps de-risk approximately 100 wells in Comanche Area 7, an area that was not highly valued at the time of acquisition; and 
  • The Company successfully tested a tight cluster completion design, in Comanche Area 5, resulting in wells that are currently producing 30-60 percent more than offset wells.


“Sanchez Energy showed strong reserve growth last year, with an 88 percent increase in the Company’s proved reserves,” said Tony Sanchez, III, Chief Executive Officer of Sanchez Energy.  “Through our acquisition of the Comanche properties and subsequent drilling success, the Company’s proved reserves increased to a record 363 MMBoe at year-end.  Importantly, we achieved a reserve replacement ratio of 762 percent in 2017, in large part due to the expansion of the step-out area from Western Catarina into Central Catarina and identification of a second Lower Eagle Ford target in Comanche.  

“Despite weather-related operational challenges in September and October of last year, the Company delivered solid production during the fourth quarter 2017 of almost 82,000 Boe/d, the midpoint of our guidance, and brought 64 gross Comanche wells on-line during the quarter.  At Briscoe Catarina South, in Comanche Area 3, we successfully completed a four-zone stack development test of 17 wells during the quarter.  The wells showed average 30-day initial production rates of approximately 1,252 Boe/d from two Lower Eagle Ford zones and 675 Boe/d from two Upper Eagle Ford zones.  At Chupadera Ranch, in Comanche Area 7, our initial Lower Eagle Ford A and B appraisal wells exceeded our estimates with an average 30-day initial production rate of approximately 640 Boe/d.  We believe this appraisal confirms the existence of two viable drilling zones, which helps de-risk approximately 100 wells in an area of Comanche that was not highly valued at the time of acquisition.

“Additionally, during the fourth quarter 2017 we began receiving positive results from tests involving a new tight cluster completion design.  During the quarter we brought a total of 9 wells on-line from three pads in Area 5 utilizing the tight cluster design.  The test wells are currently producing 30-60 percent more than offset wells completed with our standard design.  On the pad with the longest production history, the Briscoe Cochina West Ranch 84H and 85H wells have an average per well 30-day initial production rate of approximately 1,060 Boe/d, which is roughly a 50 percent increase to the offset wells which used the standard design.  Although we are far from finished with completion testing, the results from the tight cluster completion design appear to be significant.  We intend to continue to test the tight cluster completion design across other assets and areas of Comanche, in addition to other completion designs that seek to further optimize performance by adjusting frac fluids and other design parameters.

“With our continuing focus on financial discipline and delivering a sustainable business model of organic production growth while spending within cash flow, we have budgeted $420 million to $470 million in capital spending in 2018, which is a reduction of roughly $100 million at the midpoint of guidance when compared to last year.  Despite this reduced spending, we have a very active drilling campaign with an operated rig count of seven rigs and four completion spreads.  We remain on pace to reach production of approximately 90,000 Boe/d within the first half of 2018.”


During the fourth quarter 2017, the Company spud 38 gross (14.3 net) wells and completed 80 gross (35.6 net) wells.

During the fourth quarter 2017, the Company brought on-line 64 wells at Comanche, 8 wells at Catarina, and 13 wells at Maverick.  As of June 30, 2017, the Company had maximized the allowable 30 well drilling bank at Catarina that can be applied towards its current annual drilling commitment period, which extends from July 1, 2017 to June 30, 2018.  As of Dec. 31, 2017, the Company had drilled an additional 10 wells towards its annual 50 well drilling commitment for the one-year drilling period ending June 30, 2018, resulting in 40 wells in total towards the annual 50 well drilling commitment.   

As of Dec. 31, 2017, the Company had 2,165 gross (861.6 net) producing wells with 78 gross wells in various stages of completion, as detailed in the following table:

      Gross   Wells Waiting / 
  Project   Producing   Undergoing
  Area   Wells   Completion
  Catarina   389   4
  Comanche   1,582   71
  Maverick   63   0
  Palmetto   84   3
  TMS / Other   47   0
  Total   2,165   78


The Company’s production for the full year 2017 was approximately 25.7 MMBoe, or 70,320 Boe/d, which represents a year-over-year growth rate of approximately 31 percent.  Despite weather-related completion delays in September and October 2017, the Company’s fourth quarter 2017 average daily production rate was 81,977 Boe/d, which was the midpoint of the Company’s 80,000 Boe/d to 84,000 Boe/d guidance for the quarter.  The Company’s production mix during the fourth quarter 2017 consisted of approximately 34 percent oil, 34 percent natural gas liquids, and 32 percent natural gas.


The Company has hedged approximately 20,000 barrels (“Bbls”) per day of its 2018 oil production and approximately 189,000 million British thermal units (“MMBtu”) per day of its 2018 natural gas production and 10,600 Bbls per day of its 2019 oil production and approximately 48,000 MMBtu per day of its 2019 natural gas production on a consolidated basis.  Additional information on the Company’s hedge positions can be found in the Sanchez Energy Investor Presentation posted at
