About Subsurface Consultants & Associates
For more than 35 years, SCA has helped organizations strengthen subsurface capability across the global upstream energy industry.
Building Capability.
Strengthening Decision Quality.
Today, SCA operates as the Subsurface Capability Engine, integrating advisory, capability development, expertise placement, and strategic partnerships into a continuous approach that improves decision quality where risk, uncertainty, and value converge.
We support operators, national oil companies, independents, and energy organizations in more than 50 countries.
Our Foundation
SCA was founded in 1988 in Lafayette, Louisiana, by respected geoscientist Daniel J. Tearpock.
Dan recognized that the industry needed more than technical advice. It needed practical methodologies that could improve how subsurface professionals interpreted data, evaluated opportunities, and made critical decisions.
That vision led to the publication of Applied Subsurface Geological Mapping, which became one of the industry's most influential technical references and established the foundation for SCA's consulting and capability development approach.
Built on Proven Expertise
What began as a small consulting practice in Louisiana has grown into a global organization supporting upstream energy companies across the world.
Over the past three decades, SCA has expanded from technical consulting into an integrated capability model that combines:
Advisory
Capability Development
Expertise Placement
Strategic Partnerships
Today, that model is known as the SCA Capability Engine.
Why We Exist
The upstream industry is facing a growing capability challenge.
Experience is declining.
Technical complexity is increasing.
High-quality subsurface decisions have never been more important.
We believe organizations need more than individual experts or one-time consulting engagements.
They need capability that is built, applied, and sustained.
That belief drives everything we do.
What We Do
SCA helps organizations improve subsurface decision quality by integrating:
Advisory and Consulting
Capability Development
Expertise Placement
Strategic Partnerships
Rather than delivering isolated services, we embed capability into real decision environments where it creates lasting organizational value.
