Management Team

Peter Flanagan

CEO and Founder

The launch of Ubiterra marks Mr. Flanagan’s fourth company providing software solutions for the oil and gas industry.  He was also CEO for his two prior successful software companies: Parallel Geosciences, formed to provide processing and storage of seismic data for its oil and gas clients, and Reflection Software, creator of the SeisVision 3D seismic interpretation solution with attribute analysis, mapping tools, and other applications. Both solutions continue to be utilized by oil and gas companies around the globe today. Mr. Flanagan later co-founded Transzap, a cloud-based transaction accounting internet service for the oil and gas industry.   Transzap was later purchased and re-named Oildex, which today serves over 1,000 oil and gas clients as the dominant accounting transaction service in the industry.  Most recently, he shared the Society of Exploration Geoscientists (SEG) 2018 Cecil Green Enterprise Award with former Parallel Geoscience Corporation partners Daniel and Robin Herold.  Peter started his career as a geophysicist at BP Amoco in Denver, Colorado, in 1983 after earning his MS degree in Geophysics from the University of Arizona.

Nancy Hamilton


Ms. Hamilton serves as Ubiterra’s Chief Financial Officer where she is responsible for all finance and accounting functions as well as corporate legal and administrative matters.

Ms. Hamilton’s career includes merger and acquisition experience, Treasury and IT systems management and HR with various companies, many of them start-ups, some where she was COO.  In helping those companies grow, she provided guidance for global growth strategy, raising capital, corporate structure and governance. She has also been responsible for the financial and SEC compliance necessary for taking a company public (Intrado: NASDAQ), managing the subsequent Investor Relations efforts and eventual exit strategy.

In addition to being on Ubiterra’s Board of Directors, she is a member of the advisory committees for Exum Instruments. She holds a B.S. degree from Regis University in Denver, Colorado.

Dutch Thompson

Vice President of Operations

Mr. Thompson leads the company’s operations, product development and software application testing, job responsibilities he also held earlier when with Landmark Graphics and Geographix, both start-ups designed to help mid-sized and smaller oil and companies process and manage their seismic data.  While at Geographix, he provided technical and sales support for its SeisVision suite of data management tools.

Mr. Thompson’s oil and gas experience includes a wide variety of assignments across the globe, including Denver, Houston and Cairo, Egypt when with BP Amoco for nearly two decades.  Mr. Thompson met Peter Flanagan when both worked at BP Amoco, and they have worked together on several successful start-ups since.   Mr. Thompson holds a B.S. degree in Geology from Colorado State University as well as a degree in Civil Engineering from Colorado University.

Rachel Stocking

Director of Sales and Marketing

Ms. Stocking leads the sales and marketing initiatives for Ubiterra, leveraging insights gained from a decade in oil and gas.

Leading with a love for helping humans, science, and oil and gas, Ms. Stocking focuses on listening to clients and serving their specific needs. Her appreciation for oil and gas started in the Long Beach Oil Field, where she served as community relations and government affairs for an oil and gas operator, Signal Hill Petroleum. That initial role led her to discover her excitement for geoscience and engineering. Sales and marketing became the vehicle that allowed her to “geek out,” as she puts it, on technical tools that help drive the industry toward making better decisions, and better wells. She has successfully sold reflection seismology services for NodalSeismic, microseismic services for Spectraseis and ESG Solutions, and an electromagnetic frac fluid tracking tool for Deep Imaging. Her genuine caring spirit combined with her ability to understand technical concepts and communicate their value, make her an invaluable asset to her teams.

Ms. Stocking holds a B.S. degree in Journalism and Spanish from California State University, Long Beach.

He received his master’s degree from the University of Kansas in 2012, and his undergraduate degree from University of Arizona in 2010.  Andrew is a member of RMAG (Rocky Mountain Association of Geologists)
