As co-chair of the firm’s finance department, Dewey Gonsoulin leads a team that effectively and efficiently represents commercial lenders, mezzanine lenders, corporate borrowers and other financial institutions in all types of financing transactions.

For more than three decades, Dewey has devoted a significant portion of his practice to energy financing. He is widely recognized for his expertise in upstream finance and also has extensive experience in oilfield service and midstream pipeline financings. Dewey focuses primarily on credit facilities in the upstream energy sector, including traditional borrowing base credit facilities provided by senior bank lenders to independent producers as well as more complex mezzanine and development financing transactions.

Dewey is a frequent speaker and writer on topics related to upstream oil and gas reserve-based financings. Along with Senior Partner Jason Fox, Dewey co-authored “Reserve based finance – A tale of two markets” for Oil and Gas Financial Journal (2014). This four-part series is a testament to both Dewey’s and the firm’s knowledge of this sector of the industry.

In periods of economic downturn, Dewey works alongside the firm’s restructuring practice, serving as lead transaction counsel on numerous workouts and restructurings involving energy companies. Partnering with his major banking clients, he has been instrumental in assisting clients with reserved based loans, senior secured revolving credit facilities and other financing arrangements pertaining to both foreign and domestic assets.

Dewey’s extensive experience, deep knowledge, and collaborative approach make him a valuable asset to clients looking for effective and efficient representation in complex finance transactions. His work has earned him recognition in several of the leading legal directories, including Chambers USA, in which he has been ranked in Texas Banking & Finance every year since 2006. The directory notes that Dewey “boasts a strong finance practice, regularly acting on behalf of lender-side clients engaging in the oil and gas space” and that he “is a trusted adviser and expert on all relevant subject matters for RBL lenders.”

He is also recognized in IFLR1000’s Financial & Corporate and M&A Guide (2018-2023), and he has been recommended by The Legal 500 United States in Banking and Finance Law for the last 19 years (2006-2024).

In addition to chairing the firm’s finance department, Dewey has served in various other leadership roles within the firm over the years, including serving on its management committee. He currently serves as one of firm’s two hiring partners for the Houston office.
