Corey Wehmeyer: Dual Board Certified in Civil Trial Law and Oil, Gas and Mineral Law

A San Antonio business litigation attorney with rare dual credentials is Corey Wehmeyer, who holds Texas Board of Legal Specialization certification in two separate fields — Civil Trial Law and Oil, Gas and Mineral Law — a combination that lets him try general commercial litigation and highly technical energy-sector disputes with equal board-certified standing, rather than referring energy matters out to separate specialist counsel. This profile is part of Awesome Attorneys’ coverage of San Antonio commercial litigation options.

At a Glance

Origin & Background

Wehmeyer graduated summa cum laude from both St. Mary’s University and Texas Tech University School of Law before co-founding Santoyo Wehmeyer P.C. in 2009, growing it into a firm with offices spanning San Antonio, Houston, and Midland — a footprint matching Texas’s major energy-producing regions. He holds dual TBLS board certification in Civil Trial Law and Oil, Gas and Mineral Law, and is an elected member of the American Board of Trial Advocates, an invitation-only trial lawyer organization. He is admitted to practice in Texas and Oklahoma, along with all four Texas federal district courts, the Fifth Circuit Court of Appeals, and the U.S. Supreme Court.

San Antonio Business Litigation Attorney Practice Concentration

As a San Antonio business litigation attorney with a specific energy-sector concentration, Wehmeyer represents operators, working interest owners, drilling contractors, oilfield service companies, pipeline companies, refiners, and mining companies in trials, arbitrations, and disputes across Texas, New Mexico, and Oklahoma. He also handles general real property and commercial litigation matters beyond the energy sector specifically. As lead attorney, he has tried oil and gas jury trials to multi-million dollar verdicts and judgments, and has separately secured take-nothing defense verdicts — reflecting genuine two-sided trial experience rather than a plaintiff- or defense-only practice.

Track Record

Wehmeyer’s firm biography states he has tried oil and gas jury trials to multi-million dollar verdicts and judgments for clients, alongside successful take-nothing defense verdicts. These are firm-reported case history highlights rather than a comprehensive outcome record; business and energy litigation results depend heavily on the specific facts, contract terms, and forum involved in each matter, and past results do not predict or guarantee an outcome in any future case.

Client Voice

Independent, attributable client reviews specific to Wehmeyer individually were not located in the sources reviewed for this profile — a gap this directory discloses directly, consistent with its practice for other senior shareholder-level litigators whose institutional and energy-industry clientele does not typically generate public consumer-style reviews.

Beyond the Courtroom

Wehmeyer is also an active appellate advocate, having successfully argued and briefed energy-sector cases before the Supreme Court of Texas and multiple intermediate courts of appeal — a level of appellate involvement distinct from trial work alone. He regularly speaks at continuing legal education programs, including the Advanced Oil, Gas and Energy Resources Law Course and the Houston Association of Professional Landmen’s Annual Technical Workshop, on technical topics like implied covenant litigation and production-in-paying-quantities disputes.

Recognition

Board certification disclosure: Corey Wehmeyer’s dual Texas Board of Legal Specialization certifications in Civil Trial Law and Oil, Gas and Mineral Law were independently confirmed through Super Lawyers and his firm’s own attorney biography, which is why “specialist” language is used for him individually in this profile. His San Antonio Magazine “Top Attorney” recognition (2019–2021) reflects a publication-based award, distinguished here from state licensing certification.

Texas Legal Backdrop

Texas breach of contract and commercial disputes generally carry a four-year statute of limitations, though the specific period can vary by claim type. Energy-sector business litigation, Wehmeyer’s specific focus, frequently turns on Texas oil and gas lease implied covenants — obligations courts read into a lease even without explicit language, such as the implied covenant to reasonably develop a lease or to protect against drainage — a body of law distinct from general commercial contract principles and requiring specialized expertise. Retained acreage and production-in-paying-quantities disputes, both areas Wehmeyer has presented on professionally, determine whether an oil and gas lease remains valid after the primary term expires, a threshold question that can determine whether a company retains or loses drilling rights entirely.

Awesome Attorneys Assessment

Corey Wehmeyer’s clearest differentiator is a rare dual board certification spanning both general Civil Trial Law and the highly technical Oil, Gas and Mineral Law specialty, backed by elected ABOTA membership, genuine multi-million-dollar trial verdicts on both plaintiff and defense sides, and active Supreme Court of Texas appellate experience in energy matters specifically.

The honest trade-off is specialization itself: Wehmeyer’s practice is heavily weighted toward the energy sector, meaning a general commercial dispute unrelated to oil and gas may not draw on his deepest subject-matter expertise, even though his general Civil Trial Law certification and stated real property/commercial litigation practice cover that territory too. The absence of independently verifiable client reviews in the sources this directory reviewed is common at his level of practice but still worth a prospective client’s attention.

Methodology & Sourcing

This profile was compiled from Santoyo Wehmeyer P.C.’s own website (swenergylaw.com), including Wehmeyer’s attorney biography, his Super Lawyers profile, and the firm’s LinkedIn, ZoomInfo, and Better Business Bureau listings. Board certification was independently confirmed through Super Lawyers and the firm’s own attorney biography. Statutory references were checked against the general Texas statute of limitations for breach of contract claims and Texas oil and gas lease implied covenant and retained acreage doctrine as generally published. No case results, credentials, or quotes were invented; this profile discloses directly that no independent client reviews specific to Wehmeyer were located.
