Rain Oil & Gas’s goal is to build a portfolio of leasehold and non-operated positions and to realize the portfolio’s full value through the creation of partnerships with proven operators in each basin. With over 50 years of combined experience, Rain has successfully negotiated and acquired over 250,000 acres and participated on projects for more than 200 completed oil and natural gas wells. In total, Rain Oil & Gas has participated in transactions that total more than $500,000,000.

Rain Oil & Gas utilizes data-driven strategies that are complimented by relationship cultivation in order to identify assets for acquisition & divestiture at prices that are equitable for all parties involved in each transaction.
