Exhibit 99.1

Good afternoon,

For your convenience, we have attached a new investor presentation for SandRidge Energy which was filed on December 13, 2017 as a Form 425 for both SandRidge and Bonanza Creek.  This presentation will be used by SandRidge in meetings in the coming weeks with investors to discuss the benefits of our proposed transaction. In addition to providing significant new information regarding the combined company, the presentation includes the following new information regarding Bonanza Creek:

·On December 6th, 2017 Bonanza Creek entered into a new gathering and processing agreement with Cureton Front Range LLC

·We are excited about this new agreement as it provides a third independent gas processor connected directly to RMI (DCP and Sterling being the other two) and will help us to further manage the high line pressures that are currently impacting operators in the DJ Basin

·Once fully in service, the Cureton arrangement should provide us with improved flexibility to ensure the flow of our production

·Multiple RMI interconnects with multiple independent midstream companies will allow us to optimize our system and move gas to areas of lower pressure, which also relieves stress on oil production should any of the processors become capacity-constrained in the future

·Under the contractual schedule, Cureton will be connecting to the RMI system via a high pressure pipeline in late 2Q 2018 and will be building a new 60  MMcf/d cryogenic processing plant with an expected in-service date in 2H 2018

·We will also benefit from higher realizations under this new contract than from those with our existing providers

·Bonanza Creek has dedicated approximately 30,000 net acres to the agreement with no minimum volume commitment

·We continue to be pleased with the results of the 4 DUCS completed in June and July this year

·Initial EUR estimates and economics for these wells are presented in the SandRidge presentation as ~500 MBOE and ~60% IRR. See the slide presentation for pricing and cost assumptions

·We have recently brought online 5 more wells (2 SRLs and 3 XRLs) that utilized an enhanced completion design and look forward to sharing these results with you in the near future

·Additionally, we have completed drilling 4 of the 8 planned XRL wells on our French Lake acreage to the south and plan to begin completions operations during 2Q18

·The SandRidge presentation also includes a number of pro forma projections for Bonanza Creek and the combined company.  These include projections developed by SandRidge related to Bonanza Creek’s assets that were disclosed in the S-4, which was filed on Monday

Please contact me if you have any questions.  We appreciate your continued support.

Sincerely,

James Edwards

Instead, these internal reserve estimates as of December 31, 2017 are based on NYMEX future strip prices as of December 5, 2017 (approximately $50.77 - $56.65 per Bbl for WTI and approximately $2.82 - $2.89 per MMBtu for Henry Hub through 2022).

Setting the record straight

Responding To Activists’ Objections Notwithstanding inaccurate and misleading claims about the transaction Acquiring Bonanza Creek Makes Strategic and Economic Sense Complementary, development ready assets ~970 proved and unproved locations 230 PUDS 30-60% IRRs at strip pricing Bridges the gap between mature cash flow producing assets and emerging assets Reduces reliance on Mississippian Lime (production goes to less than 60% from 80% of total production) Expands our Niobrara position, which considerably improves our risk profile The Acquisition is Accretive and Value-Enhancing Acquisition is immediately accretive +15% accretive to 2018 cash flow per share +4% accretive to net asset value per share, while significantly reducing risk At least $20MM in identified annual G&A savings Further cost reductions available through operational synergies and renewed focus on cost efficiencies 29

Responding To Activists’ Objections Notwithstanding inaccurate and misleading claims about the transaction 30 Results in 15% accretion to 2018 CFPS Maintains leverage at or below 1.9x over next three years New credit facility borrowing base of $700MM with more favorable terms >$300MM of pro forma liquidity Cash/Stock Mix Results in Accretion with Prudent Level of Leverage The Acquisition is Fairly Priced Only a 17.4% premium over announcement trading price Compares favorably to per share valuation ranges implied by recent trading, comparable company multiples and net asset value 8% premium over bankruptcy valuation Misleading reports of a 75% premium are based on deeply discounted valuation in connection with a rights offering, which in no way reflects the public market valuation immediately prior to the transaction

Responding To Activists’ Objections Notwithstanding inaccurate and misleading claims about the transaction 31 The Acquisition Delivers Shareholder Value Strategic combination achieves a better long-term risk-adjusted return for our shareholders than our standalone plan Increases in market cap to over $1B More investor attention Additional research coverage Higher trading volume with better shareholder liquidity The Acquisition is Consistent with Strategy Reduces the Company’s risk profile Provides drill-ready assets to complement our ongoing North Park and NW STACK delineation Opportunistic acquisitions that complement existing assets and drive long-term shareholder value
