Our Legacy

Big 4 Services is your trusted partner for comprehensive downhole cementing solutions in the oil and gas industry. Based in Vernal, Utah, and deeply rooted in one of the most active basins in the country, we deliver high-performance cementing services that enhance well integrity, safety, and operational efficiency.

Cementing the future, honoring the past—that’s more than our slogan; it’s the heart of who we are.

Our story began in 2001, when industry veteran Blinn Tenney—after 25 years with Halliburton—founded Big 4 Cementing in Vernal. His commitment to quality and innovation quickly earned the business a reputation for excellence. In 2007, the operation was acquired by ProPetro Services, giving our team the opportunity to expand and refine our expertise across key basins like the Bakken and the Permian.

On November 1, 2024, the Vernal operation came full circle—reclaimed by the people who built it. Big 4 Services, LLC was formed by family, rooted in legacy, and driven by the same team that helped shape its success. We’re proud to once again be an independent, locally operated company—one with unmatched experience, deep community ties, and a renewed vision for the future.

What sets Big 4 Services apart is our unique combination of technical strength, agility, and local presence. We operate with fully staffed and highly trained crews, supported by in-house engineering and lab capabilities that allow us to respond quickly and effectively to client needs. Safety, efficiency, and reliability are not just priorities—they are the foundation of everything we do.

We are proud to support the Rocky Mountain region and bring the same level of expertise and commitment to every wellsite. Our team is equipped to handle even the most technical casing jobs, challenging squeeze operations, and complex plug and abandonment projects—delivering results where precision and performance matter most.

Our leadership team brings decades of hands-on industry experience:

• Beau Tenney, CEO – Beau has led operations at both Big 4 Cementing and ProPetro Services, where he served as Vice President of Cementing until returning to lead Big 4 Services in 2024.

• David Searle, Operations Manager – Starting with ProPetro Services in 2011, David worked his way up through the ranks, earning a reputation for strong leadership and operational excellence.

• Karl Chapman, Account Manager – Also joining ProPetro in 2011, Karl developed deep client relationships and a thorough understanding of the field, helping ensure successful outcomes for every job.

At Big 4 Services, we honor our legacy while embracing innovation. Our mission is simple: to deliver reliable, cost-effective, and environmentally responsible cementing solutions that keep your operations running strong—now and into the future.
