Sam Masur’s practice is concentrated in the areas of oil and gas litigation, general commercial litigation, oil and gas titles, oil and gas and oil field service company acquisitions and divestitures, and general business acquisitions and divestitures.

In both Louisiana state and federal courts, Sam litigates oil and gas and general business contract disputes involving oil and gas leases, overriding royalty interest agreements, joint operating agreements, and distribution agreements and partnership and limited liability agreements. He has participated in such actions in Louisiana, Texas, Oklahoma, and Arkansas. Sam has successfully defended several oilfield environmental claims and toxic tort claims related to ambient air quality, and has prosecuted a major oil and gas fraud case involving theft of corporate assets and breach of fiduciary duty by corporate officers. He has also successfully defended a publicly traded company in seven class action suits that sought to enjoin a board recommended take-private merger. Additionally, he has handled products liability litigation involving propane explosions.

Beyond his litigation practice, Sam represents clients in the start-up phase of their new businesses and manages asset-based and stock-based acquisitions and divestitures for exploration companies, chemical companies, oil field service companies, allied health businesses and minor league sports franchises. He negotiates and drafts the complex purchase and sale agreements for those transactions, and provides advice on corporate and financing matters to those clients.
