The Company

HD Petroleum Evaluations is a consulting company focused on helping our clients protect their property while maximizing the value of their assets.  Leases, royalty statements, and other agreements are not standard across the industry, making it difficult for mineral owners to understand if they are making decisions which result in maximizing the value of their assets. 
 
HD Petroleum Evaluations was created by Ryan Howrish and Darrell Depper.  Ryan and Darrell have over 40 years of combined industry experience working for Oil & Gas companies, in the areas of: Reservoir Engineering, Asset Evaluation, Mineral Land, Field Development Planning, and Asset Management.
 
Our experience and unique approach help our clients make informed decisions, resulting in maximum value from their assets.
