Our Team

Borehole Image Specialists. We are an LLC formed by 3 former employees of a larger borehole interpretation company. We offer a greater level of customer service than is possible from larger companies. Let us show you the difference!

Roger Reinmiller

Roger Reinmiller started working in Oil & Gas consulting straight out of college. After receiving a B.S. degree in Industrial Engineering from Northern Arizona University in 1976, Roger was hired by Dresser Atlas as an Open Hole Field Engineer. Thus began a professional association – with Dresser Atlas and its many incarnations (including Western Atlas and Baker Atlas) – that lasted 30 years. Roger’s experience ranged from Log Analyst to Business Development Manager for Technology and Geoscience – U.S. Land. After Baker, Roger worked for 10 years as Western Regional Manager and Vice President of Operations for Fronterra Geosciences. When Fronterra closed the Denver office in 2016, Roger initiated Borehole Image Specialists, LLC. As a consequence of his vast experience, Roger has expertise in all of the multitudinous facets of data acquisition from drilled wells with special expertise in borehole image log analysis and interpretation.

Before working in borehole image analysis, Ron was an Assistant Professor of Geology, at Earlham College in Richmond, Indiana, teaching Physical Geology, Historical Geology, Environmental Geology, Mineralogy, Sedimentology, Aqueous Geochemistry and Hydrogeology. Before teaching, Ron worked as a hydrogeologist cleaning up contaminated aquifers and delineating drinking water supplies in Vermont. Ron has a B.A. in Geology from Colgate University and an M.S. in Geology from the University of Vermont. Ron spent several years pursuing a Ph.D. in uranium hydrogeochemistry at Texas A & M University. Ron is a Licensed Professional Geologist in the State of Indiana (LPG #2139).  Ron is the 1st Vice President of the Rocky Mountain Association of Geologists for 2023, where he is in charge of the Publications Committee.

When not looking at image data, or chasing his 5 children around, Ron enjoys visiting outcrops, crafting homebrew, playing guitar, and watching and playing ice hockey.

Dan Martin
Senior Geologist, M.S.

Dan Martin is a geologist who has worked in the Oil and Gas business since 2006. During this time, he has worked with every facet of resistivity and acoustic image logs including; structural interpretation, facies analysis, and the integration of image logs with geomechanical studies.

Dan started his career doing field mapping and image log evaluation in the Sandino Basin of Nicaragua, and in the years since then he has analyzed and interpreted geological data from sedimentary basins all over the world. In North America he has analyzed hundreds of wells in the Permian, Mid-Continent, Rocky Mountains, Appalachian, and Fort Worth Basins.

In 2016 Dan, along with several colleagues, started Borehole Image Specialists with the goal of providing excellent solutions tailored to the fast-paced and ever-changing Oil and Gas business.

Dan has M.S. and B.S. degrees from Brigham Young University. For his Master’s thesis, Dan mapped the complex geology of Capitol Reef National Park.

When not doing geology, Dan enjoys the usual list of outdoor activities; camping, hiking, rock climbing, and skiing. He also enjoys reading poetry and World War 2 Spy novels.
