Growth Capital for Aspiring Producers

For over 25 years and 150 transactions, BlueRock Energy Partners has fueled oil and gas independents’ growth through flexible capital financing structures. With a group of industry-veteran investors, BlueRock is now poised to take our clients’ business to the next level.

While we remain loyal to smaller independents, BlueRock is now seeking investments in the $5MM-$25MM range, with potential to $50MM. BlueRock targets lower, middle market oil and gas producers seeking growth capital for acquisitions, development plans, and recapitalizations.

Our passion and expertise is providing growth capital for aspiring producers. How can we help you?

The BlueRock Method

Deal Structure: A non-recourse financial production payment via limited term overriding royalty and small permanent overriding royalty after payout.

  • Advantages:
    • Client retains upside and control of project
    • Higher advance rate vs. traditional reserve-based facility
    • Lower capital cost than selling down equity in project
    • No personal or corporate guarantees, Non-recourse project finance
    • No 3rd party engineering reports required
    • Commodity “floor” price protection available
  • What We Look For:
    • Great people.  Experienced industry professionals with Integrity
    • Specific focus, e.g., area, trend or niche
    • Administrative experience
    • Uncomplicated corporate structure
    • Projects with low-risk attractive upside potential


In simple terms, BlueRock provides the growth capital you need, and you provide us with a term overriding royalty interest until we achieve a contractual rate of return.  Once the rate of return is met, the overriding royalty interest is conveyed back to you, and BlueRock may retain a small permanent override in the project.  We require existing production on the lease you want to purchase, or already own.  We can also include any existing production from an outside lease that you would like to include in the transaction.

First, we evaluate the existing production (PDP) based on historical production and lease operating expenses. In addition, we would like to see your own engineering and economics.  If it looks like there is sufficient value to move forward, then we would like to meet with your team for the story and a technical review. 

Yes. However, because you do not control the pace of operations, we'd have to take that into consideration in how the transaction is structured and priced.

There are some significant differences in both how we calculate our advance rate and how we structure our transaction. Banks typically lend up to 60 percent of the existing PDP reserves value, with material financial covenants. They may also give some minimal value for non-PDP reserves. BlueRock typically advances up to 50% more than a commercial bank and gives considerable value to the non-PDP reserves, with no financial covenants.

The results of a sound development plan combined with the existing production should be sufficient to pay the transaction off within 4-6 years, including BlueRock's contractual rate of return. It helps to think of our capital as a better alternative to permanently selling off your equity in the project. Our goal is to give the property back to you along with the remaining upside.

A higher advance rate than a bank, it is non-recourse, no covenants, no personal guarantees are required, and you maintain your interests, upside, and control in the project. The level of cash flow and value you ultimately receive is far greater than if you sold down your working interest to a typical industry partner.

Yes, however the financial structure will be similar to a “DrillCo” type structure, distinct from our traditional production payment structure. We will fund proven reserves development drilling in attractive resource plays, underneath experienced operators. Projects require multiple upside opportunities included in the work plan with a well-developed, transparent drilling schedule.

No. However, in certain situations, BlueRock will require “floor” price protection for our clients’ share of production, which will be provided through our hedging counter-parties and included in our financing package

No. We would like to see your own technical evaluation of the properties as well as your plans for increasing production. If you already have the report, we would be happy to review it as well. Additionally, our team will analyze the project and generate our own engineering and economic projections.

If you are seeking capital for an acquisition, we'll need a purchase and sale agreement or letter of intent from the seller. Make sure to include Well API Numbers, working interest and net revenue interest, purchase statements by well for the past 12 months. Also include the lease operating expenses by category, including non-recurring costs. Give us some background information; describe the project, and what you plan to do with the funds. That should enable us to get started.
