GAILLE PLLC is an energy transactions boutique with national and international reach, including representation of matters in Africa, Asia, and South America.


GAILLE PLLC offers large firm quality and experience paired with boutique client attention. Handling a wide variety of commercial matters, we concentrate on two areas:

Global Energy Projects. GAILLE PLLC represents energy companies, investors, and governments in domestic and international exploration, production, gathering, and pipeline matters, including mergers and acquisitions, project development transactions, EPC contracts, private equity investments, and joint ventures.

Outside General Counsel. GAILLE PLLC serves as “outside general counsel” to energy companies lacking their own in-house legal departments. In doing so, we serve as a trusted, on-call counselor and advisor to business owners, managing all of their legal matters.


GAILLE PLLC takes a client-focused approach that is tailored to achieving each client’s goals and needs through cost-conscious, efficient representation. We offer a unique perspective on efficiency due to our founder’s experience as a consumer of legal services. This enables GAILLE PLLC to better design solutions that reflect the cost and value equations of each client, and more specifically, each matter. We understand the importance of value and quality, and we endeavor to deliver both along with personalized attention.


Recognizing that clients benefit from flexible fee arrangements, GAILLE PLLC considers alternatives to traditional fees. In addition to highly competitive hourly rates, we offer flat and success fee arrangements, among other options.


GAILLE PLLC’s founder is an Adjunct Professor of Management at Rice University’s Graduate School of Business and a Lecturer in Law at the University of Chicago Law School. As a global thought leader, he is the author of three energy textbooks, five peer-reviewed articles in the Energy Law Journal, and is frequently invited to speak on topics of law and the energy industry. Our founder previously practiced law with Vinson & Elkins LLP and Occidental Petroleum Corporation and was the CCO, General Counsel, and Corporate Secretary of a NASDAQ-listed exploration and production company.


GAILLE PLLC’s offices are located on the 12th floor of the San Felipe Plaza tower, in Houston’s Galleria-area.
