About Us Our Approach Team Portfolio News Contact Lime Rock Resources What We Are Looking For E&P and Oilfield Service Strategies Since 1998, we have helped build high-growth, specialized E&P and oilfield service companies worldwide. LEASE & DRILL ACQUIRE & EXPLOIT MANUFACTURERS CONTRACT DRILLERS SPECIALTY SERVICES DIVERSIFIED Niche Investment Opportunities While the amount of capital we invest is tailored to the opportunity, we generally seek to invest $50 million to $150 million in niche specialist companies to help fund their growth. GEODynamics EnerMech Proven Entrepreneurs We seek partners with a track record of exceeding goals, a proven ability to adapt to changing markets, and a history of managing successful, challenging organizations. Differentiated Growth Plan We seek to back differentiated companies that can grow faster than the industry: oilfield service companies with technological differentiation, a strategy more nimble than its larger competitors, or an offering more sophisticated than its smaller ones; and E&P companies with a geological, engineering, land, and operations edge in finding high-return and often overlooked opportunities. Capstone OiLSERV Local Expertise Whether it’s an E&P management team with a long history operating in a specific basin or a global oilfield service company having deep connections in the markets in which it operates, having local expertise is essential, in our opinion, to long-term differentiation. Commitment to Partnership We bring our value-adding global resources and patient hard work to every investment. We don’t back competing companies, and we don’t charge monitoring or transaction fees to the companies we back. We seek an equal commitment to partnership: company leaders who understand that we can best achieve our shared goals by working hard and by working together.
