Brian M. Shahan, Partner

Brian Shahan focuses his legal practice primarily on oil and gas law in Texas and New Mexico, especially in the Midland, Delaware, and Eagle Ford Basins. Brian advises clients on all aspects of oil and gas transactions, including preparing original drilling and division order title opinions for oil and gas operations, conducting due diligence for asset acquisitions, analyzing leases and pooling/unitization agreements, and drafting curative documents.

A native Texan, Brian grew up in Sherman. Prior to joining RashChapman, he gained valuable experience in the oil and gas field as a landman working in South and West Texas. Brian now uses his landman background in his current legal practice, providing clients with straightforward, practical solutions.
