Expertise You Can Trust: The Vigil Petrophysics Story
Vigil Petrophysics is founded on 30+ years of expertise in geology, geochemistry, and petrophysics, brought to life through Amanda Reynolds’ dedicated consultancy.
Our firm specializes in integrating diverse datasets – from wireline logs and core samples to fluid and pressure data – to solve complex subsurface challenges. We will ensure you get the most out of the data that you have.
The name “VIGIL” itself embodies our core identity: to be watchful, diligent, and to illuminate data, transforming it from abstract information into a decisive tool for our clients.

Our Collaborative Philosophy
Our experience has shown us the power of integration. For 15+ years, we’ve collaborated cross-functionally in the energy sector with diverse groups, including reservoir engineers, geomechanics experts, geomodelers, and geophysicists.
We understand that the best answers emerge when all data sets align, and critically, when they don’t, exploring the reasons for disagreement often reveals invaluable insights. We approach each project as a partnership, adapting our methods to the available data and the specific questions you need answered, rather than adhering to rigid requirements. We are not fixed on having every possible piece of data; instead, we focus on discerning the geology and subsurface from the available information, even if it’s incomplete.

Driven by Experience, Defined by Insight
Amanda Reynolds brings a rich background spanning geology, geochemistry, and petrophysics.
After starting in geology and earning her Master’s and PhD in geochemistry, she was recruited into the energy sector, learning petrophysics hands-on with mentors at companies like ExxonMobil and ConocoPhillips. This journey cultivated a deep appreciation for data-driven analysis and the challenge of upscaling small-scale data to answer regional questions.
She’s worked in both conventional and unconventional fields and has vast expertise in operational petrophysics, core and fluid lab measurements and workflows, and CCUS. She has worked from early exploration to late-stage development and can alter workflows to suit your needs.
Her expertise includes knowing which tools are appropriate for specific questions and interpreting the resulting data to understand pore space, fluid types, and rock flow properties. This comprehensive understanding allows Vigil Petrophysics to unlock the full potential of your assets and provide the clear answers you need to inform critical decisions.

What Makes Vigil Petrophysics Different?
Our commitment is to provide actionable insights, not just reports. We don’t just present data; we tell the real story hidden within disparate, sometimes contradictory, datasets.
We pride ourselves on helping clients discern subtle but critical differences within zones, enabling informed decisions like optimal well placement. We are among the “good ones” in the petrophysics field, offering applied expertise and timely, precise interpretations.
